How to: Set Margins of Elements and Controls

This example describes how to set the Margin property, by changing any existing property value for the margin in code-behind. The Margin property is a property of the FrameworkElement base element, and is thus inherited by a variety of controls and other elements.

This example is written in Extensible Application Markup Language (XAML), with a code-behind file that the XAML refers to. The code-behind is shown in both a C# and a Microsoft Visual Basic version.


<Button Click="OnClick" Margin="10" Name="btn1">
Click To See Change!!</Button>



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

    ' Get the current value of the property.
    Dim marginThickness As Thickness
    marginThickness = btn1.Margin
    ' If the current leftlength value of margin is set to 10 then change it to a new value.
    ' Otherwise change it back to 10.
    If marginThickness.Left = 10 Then
        btn1.Margin = New Thickness(60)
    Else
        btn1.Margin = New Thickness(10)
    End If
End Sub
