ButtonBase.Click Event

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Occurs when a Button is clicked.

Namespace:  System.Windows.Controls.Primitives
Assembly:  System.Windows (in System.Windows.dll)


Public Event Click As RoutedEventHandler
public event RoutedEventHandler Click
<button Click="eventhandler"/>


Instead of using MouseLeftButtonDown or MouseLeftButtonUp, you should use the Click event to detect a button click by the user. Because of the way that the ButtonBase class handles mouse events, MouseLeftButtonDown and MouseLeftButtonUp events do not occur when the click mode is a value other than Hover.


The following example demonstrates handling the Click event of a Button and setting its IsEnabled property.

Private Sub disableButtonClick(ByVal sender As Object, ByVal e As RoutedEventArgs)
    disableButton.IsEnabled = False
End Sub
void disableButtonClick(object sender, RoutedEventArgs e)
    disableButton.IsEnabled = false;
        <Button x:Name="disableButton" Width="200"
        Click="disableButtonClick" Content="Disabled when clicked" />
