Event Attribute syntax

When you add a button, you need to associate an event listener to it, to perform some operation. The same is applicable for adding other controls and UI layouts. The XAML allows you to use the Event Attribute syntax to define events for a specific XAML object element.

The syntax looks like a property attribute, but it is used to associate the event listener to the element. The following example demonstrates how to assign the click event to a button control:

    <Button Content="Click Here" Click="OnButtonClicked" /> 

The associated event gets generated from the code behind the XAML page, where you can perform the real action. Here is the code snippet for the event implementation of the preceding button-click event:

    void OnButtonClicked (object sender, RoutedEventArgs e) 
    { 
        // event implementation 
    }
