I am using Excel-Format="Biff" for my excel exports.

If there are no records in the grid, I get an index out of range error on clicking the export button. All other formats work fine. They just output an empty file but does not error out. I am unable to figure out why I get an index out of range error on the "biff" format export. Attached is the error details.

I also tried the code with advanced databinding using NeedDatasource event but I see the same behavior.

<telerik:RadGrid ID="rgParticipantBalances" runat="server" DataSourceID="_dataSrcBalances" OnPreRender="rgParticipantBalances_PreRender"

OnItemCommand="rgParticipantBalances_ItemCommand" OnItemDataBound="rgParticipantBalances_ItemDataBound"

OnItemCreated="rgParticipantBalances_ItemCreated" AllowFilteringByColumn="true" >

<FilterItemStyle HorizontalAlign="Left" />

<MasterTableView TableLayout="Fixed" HierarchyDefaultExpanded="false" CommandItemDisplay="Top"

DataKeyNames="" EnableNoRecordsTemplate="true">

<CommandItemSettings ShowAddNewRecordButton="false" ShowRefreshButton="false" ShowExportToExcelButton="true"

ExportToExcelText="" ExportToCsvText="" ExportToPdfText="" ExportToWordText=""

ShowExportToPdfButton="true" ShowExportToWordButton="true" ShowExportToCsvButton="true" />

<NoRecordsTemplate>

<div style="color: Red; font-size: 12px; font-family: Verdana, Arial, Helvetica, sans-serif; font-weight: bold">

<br />

Please select a plan to show activity for the specific plan.

</div>

</NoRecordsTemplate>

<telerik:GridTemplateColumn UniqueName="Participant" HeaderText="Participant" SortExpression="FullName"

<FooterTemplate>

<asp:Label ID="lblGrandTotal" runat="server" Text="Grand Total" Font-Bold="true"></asp:Label>
