I'm looking for VBA code to have TextBoxes maintain the formatting that the ControlSource has on the actual spreadsheet. I've searched throughout Chandoo but haven't been able to find any VBA code or if there are properties on the TextBox that will do this.
Controls with linked cells as TextBox do just that: as they're linked to a cell they always displays it cells content. And in this work, content, is the key: they stick to the contents and not to the format that might have been applied to the cell. so I'm afraid you'd have to use a helper cell formatted as text and link this to the control.
