Is it possible to avoid Focus on SplitContainer?

Question

The WinForm SplitContainer gets the focus when it's dragged or clicked, while the Splitter does not. The side-effect of this, is that dragging a SplitContainer bar fires Leave/Validate on other controls, and I need to avoid this.

I already tried setting TabStop and CausesValidation to False, but with no success.

Is there a way to stop the SplitContainer from getting focused? (not a big deal, I can still use the old Splitter, but I lose some nice VS properties...)

Filini,

The only time that the splitcontainer would have focus is when you are actually moving the splitter. So I would so something like this in your validating and leave events.

private void Button_Leave(object sender, EventArgs e)
{
    if(SplitContainer.ContainsFocus)
        return;
}

I reproduced your issue and when I added the above it still calls the event of course, but the code execution doesn't occur because the SplitContainer has focus while you are moving the splitter.

Hope that helps.
