I have a small problem that has been annoying me for some hours.
In my WinForms (.NET 3.5) application I create some ComboBoxes (DropDownStyle = DropDown) in a TableLayoutPanel at runtime and fill it with strings. The ComboBoxes are configured to resize automatically (Anchor = Left | Right).
The problem is that whenever the ComboBoxes are resized (i.e. the dialog is resized), the editbox portion of the ComboBox gets selected/highlighted entirely. In my opinion this creates a very confusing effect for the customer which I want to avoid.
The problem doesn't appear if the ComboBox has a fixed size.
Also note that changing the DropDownStyle is not an option - I need the possibility to enter text manually.
I already tried messing around with overriding the OnPaint method, which didn't quite work. I also tried clearing the selection in the ComboBox.Resize event, which worked in a way, but seemed like a very ugly solution - there was a lot of flicker, intentionally selected text became deselected and I would have to add the event handler to each and every ComboBox on my dialog.
Is there a better solution to this problem?
Thank you in advance.
Regards, Andy
