RadGridView ToHtml() results missing column data

[Mark]

I am creating an exported Excel file from a RadGRidView via the ToHtml() method. However, some of the columns are missing data. Below is an example of two columns from the grid. The first (Description) results in valid data. The second (Coupon) has no data in the resultant Excel column:

                        <telerikGV:GridViewDataColumn UniqueName="Description"    IsReadOnly="True" Header="Description" Width="200">
                            <telerikGV:GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <uc1:NextFocusTextBox Text="{Binding Path=Description}" IsReadOnly="True" Background="White" Height="22" />
                                    </Grid>
                                </DataTemplate>
                            </telerikGV:GridViewColumn.CellTemplate>
                        </telerikGV:GridViewDataColumn>


                        <telerikGV:GridViewDataColumn UniqueName="Coupon"         IsReadOnly="True" Header="Coupon (%/yr)" Width="95">
                            <telerikGV:GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <uc1:NextFocusTextBox Text="{Binding Path=Bond.Coupon, Converter={StaticResource ValueConverterNumericDash}, ConverterParameter=0:N3}" BorderThickness="0" IsReadOnly="True" IsEnabled="{Binding IsEnabled}" />
                                    </Grid>
                                </DataTemplate>
                            </telerikGV:GridViewColumn.CellTemplate>
                        </telerikGV:GridViewDataColumn>

The code behind to produce the results is:

private void mbToolBar_ExcelExportClicked(object sender, EventArgs e)
{
    _printFileName                = "some_location" + MainPage.Username + ".xls";

    Uri uri                       = new Uri(_wcf.InnerChannel.Via.AbsoluteUri.Replace(_wcf.InnerChannel.Via.AbsolutePath, "/PrintHandler.aspx?FileName=" + _printFileName));

    WebClient client              = new WebClient();

    client.UploadStringCompleted += new UploadStringCompletedEventHandler(client_UploadExcelCompleted);

    client.UploadStringAsync(uri, BondGrid.ToHtml());

    BondGrid.IsBusy               = true;
}

Hello,

 The grid cannot export columns with defined CellTemplate. You should handle ElementExporting and assign e.Value to desired for these columns similar to our exporting demo.
