Hi,

Thanks for your quick reply.

I am able retrieve the descendents, but, after adding to the page, only button is visible, but the rest of the controls like TextBlock, TextBox which are there inside the XAML string are not visible?

Any idea what might be the mistake??

Don't know if there is a shorter answer but you can use VisualTreeHelper to (recursively) traverse the descendents of the user control, and test whether a descendent control is a Button...

if (control is Button) { do_something(control); }

How to find control by type??

It is possible to find the control by name, as below.

UserControl ctrl = (UserControl)System.Windows.Markup.XamlReader.Load(str); // str contains some usercontrol xaml

Button button = ctrl.FindName("ID") as Button;

My problem is, is it possible to find the control by type??

Button btn = ctrl.FindControl("Button") as Button;

if more than one button control is there, then it should return the ButtonList or it should be possible to set the starting index to search for the control.

Please let me know the approach to do in the above manner?
