Hi Vasssek,

This issue has been registered in our system and is placed on the waiting list to be resolved. We have our road map planned ahead and we are working according to the plan. At this moment we are unable to provide with an estimated time for the fix.

Until the issue will be fixed, we can offer the workaround shared in the previous post.

Please excuse us for any inconvenience this may have caused.

Kind regards,
Attila Antal

The only workaround at the moment is to remove the ColumngGroup if not in use.

<telerik:RadGrid ID="RadGrid1" runat="server">
    <ExportSettings IgnorePaging="true" ExportOnlyData="true">
        <Excel Format="Xlsx" />
    </ExportSettings>
    <MasterTableView AutoGenerateColumns="False" DataKeyNames="OrderID" CommandItemDisplay="Top">
        <CommandItemSettings ShowExportToExcelButton="true" />
        <%--<ColumnGroups>
            <telerik:GridColumnGroup Name="Group1" HeaderText="Group 1"></telerik:GridColumnGroup>
        </ColumnGroups>--%>
        <Columns>
            <telerik:GridBoundColumn DataField="OrderID" DataType="System.Int32"
                FilterControlAltText="Filter OrderID column" HeaderText="OrderID"
