How to select default button in wpf dialog?

Question

I am creating a WPF dialog. It is like our normal messagebox with ok and cancel button. How to create such a dialog so that the Ok button is selected when the dialog is opened?

Answer 1

To set a Window's Default button

Set your default button's IsDefault property to true.

Note that you can also set a Window's Cancel button by setting a button's IsCancel property to true.

To set the Selected (focused) button in a Window

If you want to select a particular button then use the Focus method like this:

yourButton.Focus(); 

You might do this when a Window loads (in the Window_Loaded event).

To select a particular button when your Window opens make sure its IsTabStop property is set to true and ensure its TabIndex property is lower than any other control on the Window.
