Question

I have one windows form file that each time I open it in Visual Studio it increases the size of the controls within the designer file. If I save the form, close it in the editor, and open it again, then the controls are all a little larger than before. I can see that the size properties on the controls are all increasing within the designer file.

Can anyone explain to me how to fix this behavior?

Answer 1

To elaborate on my comment, when the designer loads/saves your form, it is going to call the getters/setters on the public properties of your Form and the Form’s controls.

This means that if you’ve overridden a property of the form, and accessing/setting said property has a side effect of resizing a control, that size adjustment will be reflected in the designer. Then when you save the form, that new size is persisted to the designer-generated code. Each time you reopen the form, this adjustment would occur.

This would also apply to event handlers for properties that are being set within the designer-generated code.
