Is it possible to have custom columns in a databound grid?
posted

I have my grid databound to an ObjectDataSource--the out of the box functionality of the grid does not cover our needs, so we were looking to extend the grid using client-side code. 

One problem--how do I add non-bound columns to the grid? When I try, it pukes. Sorry if this is a rudimentary concept that I overlooked. When I tried to use the site search for "databound grid" nothing returned. Nothing valuable was returned from "ObjectDataSource TemplateDataField" either.

    When trying to use: 

         <ig:TemplateDataField Key="ItemSelected">

                                <Header Text="Select Row" />

                                <ItemTemplate>

                                    <asp:CheckBox ID="itemCheck" runat="server" />

                                </ItemTemplate>

                            </ig:TemplateDataField>

     

    I get:
