PROBLEM

RadGridView adds an additional empty column after all gridview columns:

CAUSE

RadGridView tries to fill all the width that it takes. Actually this is not a column, but rather the rows which span to end of the GridView.

SOLUTION

You can use either of the following methods:

  • Set the ColumnWidth property of RadGridView to "*"
XAML
	<telerik:RadGridView ItemsSource="{Binding Clubs}" ColumnWidth="*" />

The result would be:

  • Set the Width of any of the columns to "*"
XAML
	<telerik:GridViewDataColumn DataMemberBinding="{Binding StadiumCapacity}" 
	            Header="Stadium" 
	            Width="*"/>

Now, the result would be:
