hi,

I am making an application in WPF, which consists of Window and a login UserControl
That user control is added as a child in MainWindow at runtime, now when i click login button of usercontrol it gets logged in and loads a new window. But i want to close the login UserControl alone not the parent window.

i have tried this code

Window parentWindow = Window.GetWindow(this);
parentWindow.Close();

but it closes the parent window not the user control.
Please help me in this!!

Thanks Regards,
Sankar

There is no such concept as "close a control".

Not only it is never needed, but it does not mean anything certain. What is that supposed to mean? You can possibly 1) hide an instance of the control; 2) remove it permanently from the the logical tree of the window.
