Form Controls
What Are Form Controls?
Form Controls are objects which you can place onto an Excel Worksheet which give you the functionality to interact with your models data.
You can use these controls on worksheets to help select data. For example, drop-down boxes, list boxes, spinners, and scroll bars are useful for selecting items from a list. Option Buttons and Check Boxes allow selection of various options. Buttons allow execution of VBA code.
By adding a control to a worksheet and linking it to a cell, you can return a numeric value for the current position of the control. You can use that numeric value in conjunction with the Offset, Index or other worksheet functions to return values from lists.

Where Are Form Controls?
Form Controls are located on the Developer Tab under Insert Form Control.
PS: If you do not have developer tab, learn how to enable it.
You will notice 2 types of Form Controls, being Form Controls and Active X controls.
This post will only be dealing with Form Controls. The Active X controls, similarities and differences will be discussed towards the end of the post.
How Do I Insert a Form Control
To Insert a Form Control goto the Form Control Menu and click on the Form Control you want to insert.
Now click on the worksheet in the location you want your form control.
Don’t worry about the location or size you can change those later.
What Are The Different Form Controls?
There are several types of Form Controls offering a range of interactivity from a simple display through to interactive controls which allow multiple selection or interactive selection of values.
| Control Name | Description | Function |
| Button | Push Button | Executes a macro |
| Check Box | Allow selection of non-exclusive options | Multiple On/Off options |
| Combo Box | Drop Down selection Box | Select items from a Drop down list |
| Group Box | Layout element which groups common elements | Nil |
| Label | A Text label | Can be static or linked to a cell |
| List Box | Fixed selection box | Select items from a list |
| Option Button | Allow selection of exclusive options | Exclusive Single On/Off option |
| Scroll bar | Allow Horizontal or Vertical scrolling | Increases or decreases a cells value by a fixed amount |
| Spin Button | Increment/decrement a value by a fixed amount | Increases or decreases a cells in steps by a fixed amount |
These are discussed individually below
Form Control Types
Button (Form Control)
The Button Form Control is as its name suggests simply a Button.
Pressing the Button allows execution of a macro.
The Button has no other controls.
Button Text
You can right click on the button and change the buttons Text (Edit Text) and enter the text you want displayed on the button.
The Button’s text can be linked to a cell, select the Button, In the formula Bar enter a link to a cell. eg: =$C$3 and accept. The Button’s text will now change as the contents of the cell C3 change.
You can change the Text Style including Font, Color and Text Direction using the Format Control (Ctrl 1) option.
Assign Macro
Right click on the Button and select Assign Macro
The Assign Macro dialog will pop up.
Select the macro you want to assign to the button.
Label (Form Control)
The Label Form Control is also as its name suggests simply a Label.
The Label will display text either fixed or from a linked cell
You can right click on the button and change the buttons text (Edit Text).
The Button’s text can be linked to a cell, select the Button, In the formula Bar enter a link to a cell
eg: =$C$3 and accept. The Button’s text will now change as the contents of the cell C3 change.
Unlike the Button you cannot change the Text Style, Font, Color or Text Direction.
Typically a label is put in front of another Control to explain or add a title to the control.
Labels would rarely be used on a Worksheet as a label as they have limited text format properties.
Users would be better served using either cell text or a Text Box where full text formatting is allowed.
Labels come into use when setting up custom Dialog Forms which are used by VBA applications for custom data entry or other uses.
Check Box (Form Control)
The Check Box form Control allows selection of a number of non-exclusive options.
That is any number of Check Box controls may be implemented and they independently be on or off and have no relationship to each other.
The Check Box Form Control returns the value indicating its status, either True (selected) or False (not selected), to a linked cell.
To link a Format Control to a cell, Right Click the Format Control and select Format Control…
Option Button (Form Control)
The Option Button form Control allows the selection of an exclusive option from a number of alternatives.
That is only one Option Button Form Control may be selected at a time, the remainder are automatically turned off.
The Option Button Form Control returns the value of the Option Button indicating its status to a linked cell.
In the Example above the Option Buttons are linked to cell E2.
You only need link one Option Button to cell E2, Excel automatically links the remaining option buttons to teh same cell.
Selecting a Different Option Button automatically deselelects the other Option Buttons and changes the linked cells value
List Box (Form Control)
The List box allows the selection of one or more items from a list.
The list is sourced from a Range of cells in the above case it was F2:F17.
The List Form Control returns an Index Number or position of the selected item to the Cell Link, 5 in the example above.
The Input Range and Cell Link are setup by Right Clicking the control and select Format Control…
The Number of items visible in the list box is determined by the size of the list box
If there are more items than will fit in the list box then a scroll bar is automatically added to the list box to enable there selection.
Combo Box (Form Control)
The Combo Box allows the selection of one or more items from a drop down list.
The Combo Box use is similar to the list box except that it has a drop down selection list instead of a fixed length selection list.
The list is sourced from a Range of cells in the example below it was F2:F17.
The List Form Control returns an Index Number or position of the selected item to the Cell Link B10, 9 in the example below.
The Input Range, Cell Link and size of the Drtop Down Box are setup by Right Clicking the control and select Format Control…
Spin Button (Form Control)
The Spin Button is a simple toggle button that allows the increase or decrease of a linked cells value by a certain pre-defined amount.
The Cell Link and Lower, Upper Limits and Step Size parameters are setup by Right Clicking the control and select Format Control…
The Lower, Upper Limits and Step Size must be Integers. If you want to increase a cell by fractional amounts you will need to for example set the range from 0 to 1000 in steps of 1 and then devide the linked cell by 10 which will give a Range of 0 to 100 in steps of 0.1
Scroll Bar (Form Control)
The Scroll Bar Form Control often referred to as a Slider is a simple linear slider that allows the increase or decrease of a linked cells value by sliding a bar either left/right or up/down.
Scroll Bars can be placed either Horizontally or Vertically by dragging the corner.
Scroll bars are incremented by the Step Size by clicking the ends of the bars or dragging the slider or by a Page Jump Size by using Page up[/down or clicking either side of the slider bar.
The Cell Link, Lower, Upper Limits, Incremental Change and Page Change parameters are setup by Right Clicking the control and select Format Control…
The Lower, Upper Limits, Incremental Change and Page Change must be Integers. If you want to increase a cell by fractional amounts you will need to for example set the range from 0 to 1000 in steps of 1 and then devide the linked cell by 10 which will give a Range of 0 to 100 in steps of 0.1
Group Box (Form Control)
The Group Box Form Control isn’t really a Form Control at all, as it allows no interactivity.
What it is used for is grouping similar controls so that functional groups of controls can be maintained and the users flow is directed around a form.
Using the Form Controls
General Use
The use of the information from a form control is limited by your imagination.
Typical uses are
- Selecting items for a chart
- Selecting data sets
- Moving data sets
- Adjusting values in a model
As described in each of the above Form Controls is that the Form Controls do not return a value directly from a list, they all return either a number or an index number relative to the position of the item in a list.
Examples of all the Form Controls and examples of their use can be found in the attached file:
Excel 2003 Examples or Excel 2007+ Examples
or
Have a browse through the dashboards presented during Dashboard Week
or
For some Extreme Examples of Spreadsheet Interactivity using Form Controls and a little bit of VBA code:
Running Macros
Apart from the Button Form Control whose only purpose is to Run Macro’s, all Form Controls can be linked to a Macro.
This is done by Right Clicking on the Form Control and selecting Assign Macro.
It is worth noting that the macro is only executed after the control is released.
EG: If you have a macro linked to a Spin Button, If the Spin Button is held down and hence repeatedly increments its value, the macro will only be executed after the control is released.
Moving and Resizing Form Controls
You can move and resize form controls as with all other worksheet Objects.
Select the form control by right clicking on it
Use the handles to resize or drag the edges to move the controls
Hint: You can use Alt while dragging or resizing to snap the control to cell boundaries.
3D, Printing & Locking Form Controls
You can lock Form Controls as well as enable them to be printed or not
Right Clicking the control and select Format Control…
Use the Size, Protection and Properties Tabs as required.
The 3D option enables a 3D version of the Control instead of a flat control, which can add a bit of sparkle in some instances.
Limitations of Form Controls
Form controls offer a limited set of functions but do those functions very well.
Limitations are Form Controls:
- Form Controls can only increase or decrease by integer numbers
- Form Controls only return the index of an item in a list
- Form Controls have limited format properties (Font, Color etc)
What are the Active X Controls
Active X controls are like Form Controls on Steroids in that they have a much wider range of properties than Form Controls.
They also have much better ties to VBA in terms of programmability and have a number of events that can be accessed programmatically.
The main limitation of Active X controls are that they use a Microsft Active X component. This means that if you are sharing your workbook with an Apple Mac user using Excel for Mac these functions wont be available as Active X isn’t avilable on that Platform.
Workbooks with Form Controls will happily work on a an Apple Mac.
Other Controls Available in Excel
A number of other Excel objects can be used to add interactivity to your worksheets.
Shapes
These include:
- Shapes
- Charts
- Text Boxes
- Word Art
All these can have macro’s linked to them which effectively act the same as a Button Form Control without the moving button effect.
A stunning example of using Text Boxes was recently posted at: The Grammy Bump Chart
Where the Artists Stats Box (Top Left of Chart) is using several Text Boxes linked to cells to show the Selected Artsists Statistics.
HyperLinks
Inserting Hyperlinks at stratgic locations throughout worksheets provides a great way to simplify navigation around pages and between pages

Hi Chandoo, I need you help in the following problem.
I'm trying to get a direccion from a found result. With this dirreccion I will want the before cell value. For example, If result of a find is 38 localized in cell $C$2, I need to get previus value (cell $B$2 ), maybe Andrés.
Do you know some way to do that?
Thank you for you help.
Hi Chandoo
Thanks for this. One thing though: In my pre-2007 version of Excel, the COUNTIF function doesn't recognise a semicolon (;), but requires a comma.
Is the semicolon an Excel 2007 thing?
Jair... I am not sure I understand what you want. what do you mean by Dirreccion?
@Lincoln: I am sorry, often I forget that I am using European version of excel where the delimiter is ; instead of ,. I have corrected the formula now.
Thanks for this nice tip, i used to do a find all after filling every new items which was cumbersome.
Do you know a way to extend this validation search to other tabs/sheets ?
Thanks for you attention. I'm trying to get of value continue from a found value. Let me show a example:
Name Years
John 35
Maria 28
Teresa 32
If I search the max years, the result is 35, but I need that result to be John. Do you know how I can do it?
@Subbu.. you can easily extend the validation to other sheets by pasting the data validations. See the latest article here: http://chandoo.org/wp/2009/10/28/copy-data-validations/
@Jair.. you can use the large() or small() formulas to do this. for eg. =index(A1:A3,large(B1:B3,1)) will get you the name of the person with highest "years". More help here: http://chandoo.org/excel-formulas/large.html
Hi, I don't know if I'm using bad the formula or its performance is diferent for my Office version. Large() formula return the value in the cell, in my example 35. The index() formula use a range, row and column. I'm using the large() as number of row, and it is bad because into the range don't have row 35. This is my perception. What do you think?
Hi, I going to prove, with this solution by JLD http://jldexcelsp.blogspot.com/2008/07/extraer-direccion-de-celda-en-matriz.html
Hello,
I am trying to attempt data validation in Excel Mobile, but the DV tool isnt available. I want to prevent duplicates is all, any advice on acheiving this in Excel Mobile? Thanks..
@Jair... my french aint that good. it starts at "merci" and ends at "beau coup".
Anyhow, you need to merge the large with vlookup to do this. I am not sure if you have solved the problem. Otherwise let me know with details and I can write the formula in comments.
@Chad... I have never used excel mobile, so I have no idea. May be they have not implemented data validations in excel mobile.
Any excel mobile users out there?
Hi Chandoo, the proposed solution by JlD is interesting. He created a macro to get values when the matrix is not one dimensional, how on my problem. This fuction for me.
I would like to share you my work, how can I upload?
@Jair.. sorry for such a delayed reply.. you can upload the files to skydrive and link them here. Or you can email them to me at chandoo.d @ gmail.com and I will upload them somewhere. But it could take forever if you email files to me as I am a bit lazy.
[...] Day 31: Advanced Data Validation Tricks in Excel – Part 2 [...]
Hi,
Can you help me in Microstrategy?
Br,
Moin
really wonderful article. I feel it is implementing Primary Key concept into spreadsheets.
Hi article on data validation. Excel is a very versatile platform to work with and we use it for all kinds of data tabulation. In fact this must have been the most rudimentary data management tools I must have worked with and knowing such tips only adds functuionality to our user experience. Great article. looking forawrd to read more.
Hi Chandoo,
Thanks for such a nice idea.
I tried copy paste the data into the validated area, but the pop-up msg (warning msg) doesn't came. Is it something that we need to update the data manually each time,.
Do we have any option where we can bulk upload the number and it throws a warning message that the data already exits and do we want to continue with this ?
Please do reply me.
Thank you.
Regards,
Vasanth.
It was really useful chandoo...thanks a lot...
Tried this in excel 2010 and it did not work?
Could the newer excel have changed that much?
@Leo
It works fine in Excel 2010
The formula used above =COUNTIF($B$4:$B$11,B4)<=1
only applies to the range B4:B11
Did you adjust the range to your data?
This page helped me accurately to find solution of my question. thanx
we want to prevent duplicate entries in three columns combined, using data validation, i.e. say, column A has first name and Column B has middle name, Column C has last name. the first name can be duplicate, middle name can be duplicate, last name can be duplicate, but not all three at the same time.

Hi, I've tried above validation method to prevent duplicate value from entering into the cells. It's work, when user key in the data into the selected range. However, it's not working when user copy-&-paste the info into the same range.
Please advice. Thanks.
Hi Chandoo,
Does it work in Excel 2007?
Please Reply
thanks chandoo........
it does not work when data is copy pasted...any solution for this??
hi i m shaloo and i want to know in excel if i write duplicate no.then it says or show about we are write duplicate no.
Hi Chandoo
I've tried using this with a Named Range, which is actually a column in a Table as DV wont accept a table reference, and it wont work.
Also tried using Offset to specify the Named Range, but that wont work either.
Is it possible to use Named Ranges with DV?
Thanks
Kris
I have tried the above formula on a table column. The Error box does not pop up, there is only the small ! next to the cell with the duplicate. The column I am working with is formulas that produce a date. Is the reason it doesn't work that the cells contain formulas rather than data?
The formula works but only if I enter data in cell above it. So for example, if I have "123" in B11 it does not allow me to enter "123" in B10, B9, B8, etc. But I can still enter "123" in B12. Please help! 🙂
Great tip.. thanks a lot
I have 21 years of experience working as data entry assistant. I constantly read several blogs to keep myself up-to-date with the advances in data entry profession. I really enjoyed this blog post. From my several years of experience, I agree with you 100% when you say, “ We all know that data validation is a very useful feature in Excel. You can use data validation to create a drop-down list in a cell and limit the values user can enter. ”
Keep blogging. I will come here again.

Hi,
This is really very helpful.
Thank you
how can i assign two validation on a single cell
one is for list validation (means the data should be from that range)
second i want to prevent them from repetition
how can i do this ?
P7 to P506 have GR# which are for list
