 ## Example  
  The following example creates a <xref:System.Windows.Controls.Grid> element with a <xref:System.Windows.FrameworkElement.Name%2A> of `grid1`. The <xref:System.Windows.Controls.Grid> contains a <xref:System.Windows.Controls.StackPanel> that holds <xref:System.Windows.Controls.Button> elements, each controlled by a different collection method. When you click a <xref:System.Windows.Controls.Button>, it activates a method call in the code-behind file.

  This example defines a series of custom methods, each corresponding to a <xref:System.Windows.Controls.Primitives.ButtonBase.Click> event in the [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] file. You can change the number of columns and rows in the <xref:System.Windows.Controls.Grid> in several ways, which includes adding or removing rows and columns; and counting the total number of rows and columns. To prevent <xref:System.ArgumentOutOfRangeException> and <xref:System.ArgumentException> exceptions, you can use the error-checking functionality that the <xref:System.Windows.Controls.ColumnDefinitionCollection.RemoveRange%2A> method provides.
