The custompanels load inside of a splitcontainer at runtime. When the user clicks on the custompanel, it should reduce to half the size but with only 4 specific textboxes. How can I do this? To recap: I need the custompanel to reduce to 4 textboxes from 10 when the user clicks on it. Thanks in advance for any help.

SplitContainer itself, as far as I can tell, is not an option; it will raise an exception unless used in Visual Studio’s Designer.My implementation would look roughly like this, except that I’m not receiving the necessary mouse events. I’ve tried event handlers, On* overrides and overriding WndProc in the user control itself, the
