resize events on windows form

[Tarren]

Hi:

I am trying to get access to the event after a window has been resized. The
events I have been using SizeChanged and Resize all fire after any pixel
size change.

What I am trying to achieve is after the window has been dragged to a new
size (or maximized/restored) then I redraw the images within the form.

If I do it on Resize, then it tries to redraw as the form is being resized,
which is not what I want. Is there some way I can get to the event and fire
only after they are done resizing?

Thanks.

Set a flag (boolean variable) to true in the Resize event. Then, in
the MouseUp event, check the flag. If true, reset to false, and
perform your resizing code.

thanks! I will try that out

Why you recommend so sophisticated solution ?

Form has ResizeEnd event which is designed for this. So your trick is not
required.

I was not familiar with the ResizeEnd event.

If nothing else, it would be a good exercise to do. Helps to
understand form event handling.

Yes. Handle the ResizeEnd event instead of Resize or SizeChanged.

Note that if you're handling this in the form class itself, you should
override OnResizeEnd instead. The documentation states "The
OnResizeEnd method also allows derived classes to handle the event
without attaching a delegate. This is the preferred technique for
handling the event in a derived class."
