problem with custom control creation

Question

Hi I created a custom control that inherits from textbox in a dll WindowsControlLibrary. In my main project the custom control appears in the toolbox. I can drag it to the form OK but if I click away from it to another control I can't click back. But if I drag another control to the form say a label and then delete the label focus jumps to my custom control again. Anybody know what is going on here? Andy

Thanks for the reply. I was using an override ProcessDialogKey method in the class to handle enter key etc. and I think that was somehow messing me up. When I commented it out it worked fine. I have since been able to use an override ProcessCmdKey method with no problems. I'm not sure the difference... Andy

Andy: You'd mentioned WindowsControlLibrary so I am not sure what you have; is this a user control? If you create a standard class and inherit TextBox using no more code than what follows I don't see that behavior: using System; using System.Collections.Generic; using System.Text; namespace junk { public class XTextBox : System.Windows.Forms. TextBox { public XTextBox() { InitLayout(); } } }
