Hi, I used some excel export code previous posted on a thread. It works great, but I'm wondering if we can intercept midway. I'm looking to add a value on the top row then followed by the chart.

public static void Export(RadGridView grid)
{
    const string extension = "xls";
 
    var dialog = new SaveFileDialog
    {
        DefaultExt = extension,
        Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, "Excel"),
        FilterIndex = 1
    };
 
    if (dialog.ShowDialog() != true)
    {
        return;
    }
 
    using (var stream = dialog.OpenFile())
    {
        var exportOptions = new GridViewExportOptions
        {
            Format = ExportFormat.ExcelML,
            ShowColumnHeaders = true,
            ShowColumnFooters = true,
            ShowGroupFooters = false,
        };
        exportOptions.Items = (IEnumerable)grid.ItemsSource;
        grid.Export(stream, exportOptions);
    }
}

Hello Minh,

RadGridView provides two events which fire when you export data from RadGridView in the ExcelML format - ElementExporting and ElementExported. You can handle them in order to format the cell values to be exported or if you want to write additional data to the stream.

I hope you find this information helpful.
