Filter on Grid Template Column with Expression?

[Farhan]

Hi,
   I have been trying to get this to work and need some help, I have a grid Template Column and have an expression to evaluate boolean values if its true or false in the Item Template, I need to filter on these values, how can I do this? In other Itemtemplate examples I have seen recommentdations to use Datafield but If i
use the
Datafield = "IsPrivateBank" ....it takes away the Filter from column header and just leaves a checkbox, since its taking it as a boolean value

and If I use the Expression in the datafield like

DataField = "<%# Convert.ToBoolean(Eval("IsPrivateBank")) == false ? "Federal" : "Private" %>"

this results in an error too. How can I filter on the values the user sees i.e "Federal" or "Private"  Please provide code example with your help, thanks in advance!!

<telerik:GridTemplateColumn HeaderText="Type" HeaderStyle-HorizontalAlign="Left" HeaderStyle-VerticalAlign="Bottom" ItemStyle-HorizontalAlign="Left" SortExpression="IsPrivateBank">
    <ItemTemplate>
        <asp:Label ID="lblBankType" runat="server" Text='<%# Convert.ToBoolean(Eval("IsPrivateBank")) == false ? "Federal" : "Private" %>'></asp:Label>
    </ItemTemplate>
</telerik:GridTemplateColumn>
