    resize event handler

    Hi,

    I have an event handler that gets called whenever my panel is being resized.
    Since a lot of painting is going on whenever my component is being resized,
    I would like to paint my component only when the last resize event has been
    received; in other words, when the user has released the left mouse button.

    Anyone has any suggestions on how to implement this?

    thanks
    LK

      Why don't you handle the Paint event instead and do your painting
      there?

          Because even the paint event gets called several times before the user is
          done resizing the component. If it got
          called just once after the resizing was done, that would
          be just what I wanted.

              Yes, but you might not have to draw everything every time. Check the
              ClipRectangle property of the PaintEventArgs, and only paint the parts
              within that area.
