I have a RadGridView with the following properties:

telerik:RadGridView x:Name="SearchResult_DataGrid"

Grid.Row="2"

AutoGenerateColumns="False"

IsReadOnly="True"

RowIndicatorVisibility="Collapsed"

CanUserFreezeColumns="False"

CanUserResizeColumns="False"

DataContext="{Binding}"

ItemsSource="{Binding Path=Data}"

SelectedItem="{Binding Path=SelectedItem, Mode=TwoWay}"

MouseRightButtonDown="SearchResult_DataGrid_MouseRightButtonDown"

ShowGroupPanel="False" >

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Date}" Header="Date"/>

<telerik:GridViewDataColumn Header="Week" DataMemberBinding="{Binding Week}" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

When I try to sort by week, I get the "classic" string-sort problem, e.g.

10
11
4
42
7

I've tried setting the DataType programatically:

var column = SearchResult_DataGrid.Columns["Week"] as Telerik.Windows.Controls.GridViewBoundColumnBase;

if (column != null)

{

column.DataType = typeof(int);

}

But it doesn't help.
I've searched high and low in the forum and stumbled upon someone mentioning a numerical column, but I can't find that in the documentation. It seems a bit overkill to make custom sorting on a column that contain integers, so I would very much like to find a solution to this problem, since I have other columns with the same problem.

So - how do I sort a column based on numerical values?

I'm using the Q3 2011 version

Best regards
