Loss of Focus issue with PopupControlContainer

[Dave Sausville]

I''ve noticed that when using a PopupControlContainer, the main dialog losses focus when one of the controls within the popup has focus. This causes an extremely ugly flicker (main app title bar goes grey) as focus shifts from my main app, to the popup, and then back to the main app. This issue is easy to see in your own PopupControlContainerDemo project.

Is there anyway to prevent this flicker?

Thanks,
Dave Sausville

Hi Dave,

Sorry for the inconvenience caused. This behavior is by design of PopupControlContainer. PopupControlContainer acts as a separate container and hence form lose its focus when controls inside PopupControlContainer receives focus.

Mano

Hi

You can achieve through the show method of the popupcontrol.But the problem is you should handle the closing operations explicitely using the hide method.

to show popup

Point p=this.popupControlContainer1.ParentControl.Location;
p.Y=p.X+this.popupControlContainer1.ParentControl.Height ;
popupControlContainer1.Location=p;
popupControlContainer1.Show();

you can use the leave,validated events for closing the popup

good luck

Using 3.2.1

Thanks for the .Show() suggestion but that didn''t work. I replaced the my ShowPopup() with your suggestion, but the popup did not display.

Hi

sorry . there is some mistake in the line

p.Y=p.X+this.popupControlContainer1.ParentControl.Height ;

so please change to

p.Y=p.Y+this.popupControlContainer1.ParentControl.Height ;

Best of luck
