Inheriting from the tabcontrol

[thepersonof]

Hi I have I a class that inherits from TabConrol called MyControl. I have a class that inherits from TabPage called MyTabPage, as below: (heavily simplified) class MyTabControl:TabControl { protected override void OnKeyDown(System.Windows.Forms.KeyEventArgs ke) { (this.SelectedTab as MyTabPage).PanelContained.KDown(ke); base.OnKeyDown(ke); } } class MyTabPage : TabPage { private MyPanel panelContained; public MyPanel PanelContained{ get { return panelContained; } set { panelContained = value; } } } How can I override SelectedTab to return a MyTabPage? If I add a MyTabPage and change the panelcontained property, this is null again when I convet it back from SelectedTab. Seeing as it inherits from TabControl is there a nice way to make it so that I can convert it back into a MyTabPage without losing the added property? cheeers

You can't change the return type or the method parameter types in an overload.

TabControl tabs = new MyTabPage(); //ok since TabControl is a base class Since tab control does not have the PanelContained property you will not beable to use it in tabs unless its cast back up to MyTabPage. Even though the compatible TabControl contains a MyTabPage the PanelContained property will not be exposed. You will have to do this. ((MyTabPage)tabs).PanelExposed
