[Solved] DataColumn nor a DataRelation

[Darren]

Hi there,

I've got a gridtemplatecolumn which gives the following error when I try to use the filter.
ERROR: "is neither a DataColumn nor a DataRelation for table DefaultView. "

The column I am trying to filter is:

                    <telerik:GridTemplateColumn HeaderText="Description" EditFormColumnIndex="1" SortExpression="Description"
                        UniqueName="Description">
                        <ItemTemplate>
                            <%#Eval("Description") %>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>

Thanks,

Hello Darren,

How do you bind your grid? If you are using the SimplaeData binding techniques then probably you can switch to advanced binding with NeedDataSource event handling instead of using simple binding with DataBind calls. You can use advanced binding through the NeedDataSource event or data source control as demonstrated in the help link below:
Advanced Data Binding

Hope this helps..

Hi Princy,

I am using:

        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:RadCMSConnectionString %>"
            SelectCommand="SELECT * FROM [tblUser]"></asp:SqlDataSource>

 <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
            GridLines="None" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True"
            OnItemCommand="RadGrid1_ItemCommand">
            <PagerStyle Mode="NextPrev" />
            <MasterTableView DataKeyNames="UserId" DataSourceID="SqlDataSource1">

Do you still suggest NeedDataSource event?
