Keep size when AutoSize is turned off

I have a form which initialy sizes itself to its contents (a UserControl placed on location 0, 0) by setting AutoSize to true and AutoSizeMode to GrowAndShrink.

After initialization, I want the form to take control and turn off AutoSizing and make the UserControl Dock.Fill.

The problem is that when turning off AutoSize, the form regains its previous size instead of keeping its current size. I can store the Size before turning off AutoSize, and restore it afterwards, but you still get sizing events (you could see the form flicker).

Is there any way to have a form keep its current size and not have any sizing events fired when turning off AutoSize?

Solution

  • Try setting the MinimumSize property of the form before turning off the AutoSize property:

    this.MinimumSize = this.Size;
this.AutoSize = false;
