    Hello,

    I am trying to export only selected rows in excel but while exporting, item.selected is always returning false in ItemCommand, GridExporting

    case "ExportToExcel":
                        e.Canceled = true;
                        GridDataItem item3 = (GridDataItem)e.Item;
                        if (item3.Selected)
                        {
                            string Str = item3["ITEM_ID"].Text.ToString();
                        }
                        break;

    In  GridExporting

    protected void rgDeviceApproval_GridExporting(object sender, GridExportingArgs e)
        { foreach (GridDataItem item in this.rgDeviceApproval.MasterTableView.Items)
            {
     
                if (item.selected)
                {
               }
    }
    }

    In ExportToExcel,  Item.selected is working but not in grid exporting Event.

    Is there any way to update excel output in item command. I am changing excel output in grid exporting by replacing html in e.exportoutput, but unable to do it in item command.

    Hi Atif,

    If you have enabled paging with IgnorePaging export property set to "true", the selected items will be cleared within the OnGridExported event, because the control will rebind in order to retrieve all items before the export. If the IgnorePaging is set to "false", you can set the Visible property of the non-selected items:
    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.ExportToExcelCommandName)
        {
            foreach (GridDataItem item in RadGrid1.Items)
            {
                if (!item.Selected)
                {
                    item.Visible = false;
                }
            }
        }
    }

    For more information regarding the export functionality, please refer to our documentation: 
    Hope this helps.

    Thank You so much Konstantin. IgnorePaging=false solved my issue. I should have read documentation first. MY BAD :)
