XAML Object Element Usage

<RepeatButton>
  Content
</RepeatButton>

Remarks

Content Model: RepeatButton is a ContentControl. Its content property is Content. For more information on the content model for RepeatButton, see Controls Content Model Overview.

The RepeatButton class represents a control that is similar to a Button. However, repeat buttons give you control over when and how the Click event occurs. The RepeatButton raises the Click event repeatedly from the time it is pressed until it is released. The Delay property determines when the event begins. You can also control the interval of the repetitions with the Interval property.

Dependency properties for this control might be set by the control’s default style. If a property is set by a default style, the property might change from its default value when the control appears in the application. The default style is determined by which desktop theme is used when the application is running. For more information, see Themes.

Examples

The following example shows how to create a RepeatButton.

XAML

<RepeatButton Width="100" DockPanel.Dock="Top" 
              Delay="500" Interval="100" 
              Click="Increase">
  Increase
</RepeatButton>

<TextBlock Name="valueText" 
           Width="100" DockPanel.Dock="Top" 
           TextAlignment="Center" FontSize="16">
  0
</TextBlock>

<RepeatButton Width="100" DockPanel.Dock="Top" 
              Delay="500" Interval="100" 
              Click="Decrease">
  Decrease
</RepeatButton>

Visual Basic

Private Sub Increase(ByVal sender As Object, ByVal e As RoutedEventArgs)

    Num = CInt(valueText.Text)

    valueText.Text = ((Num + 1).ToString())
End Sub

Private Sub Decrease(ByVal sender As Object, ByVal e As RoutedEventArgs)

    Num = CInt(valueText.Text)

    valueText.Text = ((Num - 1).ToString())
End Sub

void Increase(object sender, RoutedEventArgs e)
{
    Int32 Num = Convert.ToInt32(valueText.Text);

    valueText.Text = ((Num + 1).ToString());
}

void Decrease(object sender, RoutedEventArgs e)
{
    Int32 Num = Convert.ToInt32(valueText.Text);

    valueText.Text = ((Num - 1).ToString());
}
