'Usage
 
Dim instance As ButtonSpinner

[TemplatePart(Name="PART_IncreaseButton", Type=System.Windows.Controls.Primitives.ButtonBase)]
[ContentProperty("Content")]
[StyleTypedProperty(Property="FocusVisualStyle", StyleTargetType=System.Windows.Controls.Control)]
[XmlLangProperty("Language")]
[UsableDuringInitialization(true)]
[RuntimeNameProperty("Name")]
[UidProperty("Uid")]
[TypeDescriptionProvider(MS.Internal.ComponentModel.DependencyObjectProvider)]
[NameScopeProperty("NameScope", System.Windows.NameScope)]
public class ButtonSpinner : Spinner

Remarks

You can wrap any element by placing it inside the content area of the ButtonSpinner control.

The Spin event lets the developer know which direction the buttons are spinning: SpinDirection.Increase indicates an increment; SpinDirection.Decrease indicates a decrement.

Example

The following example creates a simple numeric up/down control by wrapping a TextBox.

XAML

<xctk:ButtonSpinner Spin="ButtonSpinner_Spin">
            <TextBox Text="0" HorizontalContentAlignment="Right" />
</xctk:ButtonSpinner>

The following example shows an implementation of a Spin event handler.

private void ButtonSpinner_Spin(object sender, Microsoft.Windows.Controls.SpinEventArgs e)
{
    ButtonSpinner spinner = (ButtonSpinner)sender;
    TextBox txtBox = (TextBox)spinner.Content;

    int value = String.IsNullOrEmpty(txtBox.Text) ? 0 : Convert.ToInt32(txtBox.Text);
    if (e.Direction == Microsoft.Windows.Controls.SpinDirection.Increase)
        value++;
    else
        value--;
    txtBox.Text = value.ToString();
}
