Group on GridTemplateColumn - Can not format Group Text

[Kent Williams]

I have a GridTemplateColumn that I (finally) got the grouping to work how I want it to. However -- since this data is really a DateTime, it's showing up as "Loan Period: 01/01/2009 12:00:00 AM" instead of "Loan Period: 01/01/2009". How can I format ({0:d}) the group text?

            <telerik:GridTemplateColumn HeaderText="Loan Period" Groupable="true" DataField="BwrLoanStart"
                SortExpression="BwrLoanStart" UniqueName="LoanPeriod" AllowFiltering="false" GroupByExpression="BwrLoanStart Group By BwrLoanStart">
                <ItemTemplate>
                <%# utils.removeEmptyDash(string.Format("{0:d} - {1:d}",Eval("BwrLoanStart"), Eval("BwrLoanEnd"))) %>
                </ItemTemplate>
                <ItemStyle CssClass="certcolpadding" />
            </telerik:GridTemplateColumn>

All of the DateTime objects are gaurenteed to have the same time (12:00:00 AM). I kept everything as DateTIme objects instead of strings to ensure the correct sorting of the column.

Thanks!

Hi Kent,

Try accessing the GridGroupHeaderItem in the ItemDataBound event and format the text accordingly. Refer the following help article which explains how to access and customize the GridGroupHeaderItem.
