In VS2005, I made a WinForm UserControl which contains a ComboBox and a TextBox. When put this user control on the Form in design time, I can use mouse to select the ComboBox and input text, but I can't do that in TextBox. What's wrong in ComboBox?

Thanks,

Through roughly debug, it is bug of .NET WinForm ControlDesigner, it doesn't hook child window of a control which is child of another control. Details can see code of HookChildControls and HookChildHandles methods in ControlDesigner class.
