.NET Framework Class Library for Silverlight

ButtonBase..::.Click Event

Occurs when a Button is clicked.

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

Syntax

Visual Basic (Declaration)

Public Event Click As RoutedEventHandler

Visual Basic (Usage)

Dim instance As ButtonBase
Dim handler As RoutedEventHandler

AddHandler instance.Click, handler

public event RoutedEventHandler Click

XAML Attribute Usage

<button Click="eventhandler"/>

Remarks

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.

Examples

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

Visual Basic

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;
}

XAML

        <Button x:Name="disableButton" Width="200"
        Click="disableButtonClick" Content="Disabled when clicked" />
