Add parameter to Button click event

Question

Initiate
<         


        

Answer 1

Simple solution:

In your handler, cast the sender object to Button and access the Tag property:

var myValue = ((Button)sender).Tag;

A more elegant solution would be to use the Command pattern of WPF: Create a Command for the functionality you want the button to perform, bind the Command to the Button's Command property and bind the CommandParameter to your value.
