Print Button inside DataTemplate? How to write code

I have a ContentControl element whose ContentTemplate is determined at run time from the Resource Dictionary. In the datatemplate I have a visual (Convas) and what I want is to also have a button in datatemplate which when clicked should print the visual element(canvas)开发者_C百科. As I said that the DateTemplate is inside the Resource Dictionary so How can I write a Code on Click Event of that button and where it should be?

Any response would be much appreciated.

Sounds like you can use the Button.Click attached event. Just add it to the ContentControl.

<ContentControl 
    Button.Click="Button_Click" 
    ContentTemplate="<template with a button>"   
/>

and the handler:

private void Button_Click(object sender, RoutedEventArgs e)
{
}

If you have multiple buttons in your template, you can use e.Source to figure it out. And I think you can use MouseButtonEventArgs instead.
