my TemplateColumn In RadGrid (Telerik) is like below :
<telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Benefit"
HeaderText="Benefit" UniqueName="TemplateColumn_Benefit" FilterImageToolTip="Filter">
<ItemTemplate>
<asp:Label ID="lblBenefitInsideGrd" runat="server" Font-Size="11px" Text='<%# (bool)Convert.IsDBNull(Eval("Benefit")) ? "<span class=\"lblInsideGrd\">Empty</span>" : String.Format("{0:#,0 Dollar;#,0- Dollar}", Eval("Benefit")) %>'></asp:Label>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
</telerik:GridTemplateColumn>
the showfooter property of RadGrid Is true ...
when add the below properties to this template column , so we will have an exeption ...
properties : FooterText="my sum" Aggregate="Sum"
error message : Sum is not supported for type "System.Object"
how can i have sum of such these columns in radgrid ?
thanks in advance

You have to add the DataField="Benefit" to the GridTemplateColumn.
<telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Benefit" DataField="Benefit"
HeaderText="Benefit" UniqueName="TemplateColumn_Benefit" FilterImageToolTip="Filter">
<ItemTemplate>
<asp:Label ID="lblBenefitInsideGrd" runat="server" Font-Size="11px" Text='<%# (bool)Convert.IsDBNull(Eval("Benefit")) ? "<span class=\"lblInsideGrd\">Empty</span>" : String.Format("{0:#,0 Dollar;#,0- Dollar}", Eval("Benefit")) %>'></asp:Label>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
</telerik:GridTemplateColumn>
