Hi There,

I have a sorting issue with the webdatagrid and perhaps you can help.

I am using a linqdatasource and the main table this is pointing to is a table of foreign keys mostly.

I am using Templated fields to bring in data from the other tables and hiding the Id fields.

See samples code.

<ig:TemplateDataField Key="RevenueLine">

                 <ItemTemplate>

                     <asp:PlaceHolder ID="plcRevenueLine" runat="server">

                     <%#DataBinder.Eval(DirectCast(Container, Infragistics.Web.UI.TemplateContainer).DataItem, "RevenueLine.REVL_Description")%>

                     </asp:PlaceHolder>

                 </ItemTemplate>

                 <Header Text="Revenue Line" />

             </ig:TemplateDataField>

             <ig:BoundDataField CssClass="hiddenColumn" DataFieldName="PRDM_CMPY_ID"

                 Key="PRDM_CMPY_ID" Width="0px">

             </ig:BoundDataField>

             <ig:TemplateDataField Key="Company">

                 <ItemTemplate>

                     <asp:PlaceHolder ID="plcCompany" runat="server">

                     <%#DataBinder.Eval(DirectCast(Container, Infragistics.Web.UI.TemplateContainer).DataItem, "Company.CMPY_Description")%>

                     </asp:PlaceHolder>

                 </ItemTemplate>

                 <Header Text="Company" />

             </ig:TemplateDataField>

             <ig:BoundDataField CssClass="hiddenColumn" DataFieldName="PRDM_PVTL_ID"

                 Key="PRDM_PVTL_ID" Width="0px">

             </ig:BoundDataField>

My question is, can I sort by these items? For example when a user clicks the “Company” column, I want to sort the grid by “Company.CMPY_Description”. How do I set this up.

Thanks for any advice.
