How to access button in some other cs file

[Aslesh]

Hi i am using WPf for my app. I have created a button. I disabled that button by default. I want to enable that button in some other file( not code behind) in the project at some point of time according to my logic ( in different cs file). How can i access that button? Does any one have any idea how to do this. Santhapur.

You can use the LogicalTreeHelper class to find the button. Alternatively, you can use the FindName method in the FrameworkElement class.
