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.
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
