We have the following scenario where we can not provide a DataField because the item template is binded during ItemDataBound.

            <telerik:GridTemplateColumn HeaderText="Action"  AllowFiltering="false" UniqueName="Action" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="10%" >
                <ItemTemplate>
                    <TLMASP:Label ID="TransactionActionLabel" runat="server" ></TLMASP:Label>
                </ItemTemplate>
            </telerik:GridTemplateColumn>

How can we provide search functionality ?
We have an object like: 
AuditItem
{
 int id;
 ....
 Object MyObject;
}

TransactionActionLabel.Text is filled by = Cache.Get((ITransactionCapable)item.dataitem.MyObject).TransactionAction;

Should we change the way we bind the data to our grid? should we provide something like a Bindable object full of all the properties already? So the grid will interact with just a collection of these simple objects?

Bests, 
Alan.

Hello Alan,

You can try defing your own FilterTemplate for the problematic column and then handle the filtering manually. Find the below resources for more information:
