Grouping - GridTemplateColumn

[azin ramezani]

I have a GridTemplateColumn like this:

<telerik:GridTemplateColumn UniqueName="PrsSex" GroupByExpression="PrsSex Group By PrsSex">
    <HeaderTemplate>
      <asp:Label runat="server">PrsSex</asp:Label>
    </HeaderTemplate>
    <ItemTemplate>
      <asp:Label
Text='<% #Eval("PrsSex").ToString()== "0" ? "Female" : "Male" %>' runat="server" />                                            </ItemTemplate>
</telerik:GridTemplateColumn>

I want to change its name in groupPanel from "PrsSex" to "Sex". In GridGroupsChangingEventHandler I am trying to change its HeaderText like below, but it does not work!

private void grdPrs_GroupsChanging(object source, GridGroupsChangingEventArgs e)
    {
        //Expression is added (by drag/grop on group panel)
        if (e.Action == GridGroupsChangingAction.Group)
        {
            if (e.Expression.GroupByFields[0].FieldName == "PrsSex")
            {
                e.Expression.GroupByFields[0].HeaderText = "Sex";
            }
     }
}

Thanks.

Hello azin,

You should use  group expression's SelectFields instead of GroupByFields. Similar to the following:

protected void grdPrs_GroupsChanging(object source, GridGroupsChangingEventArgs e)
    {
        //Expression is added (by drag/grop on group panel)
        if (e.Action == GridGroupsChangingAction.Group)
        {
            if (e.Expression.GroupByFields[0].FieldName == "PrsSex")
            {
                e.Expression.SelectFields[0].HeaderText = "Sex";
            }
        }
    }

Thanks Rosen!
also, I want to modify the HeaderValue. Now it shows 0 and 1 infront of HeaderText, I want to change it for example to Male or Female. How can I handle that?
