Communication between parent and child window in wpf

Question

Hi, I have a parent window which launches a child window, after doing some selection/ operation in the child window is closed and i want to send some info back to the parent window (a custom class object) , whats the best way to accomplish this in wpf using the features provided by wpf ?

Thanks in advance !

Answer 1

You have many options:

• You could use a custom event in your child window that the parent window listens to
• You could define a delegate in the child window that references a method in the parent window
• You could change the constructor for the child window to take a reference to the parent window and call a method on the parent window using that reference
• You could possibly use the VisualTreeHelper class to get the parent window and call a method on that reference
