Hi,

I'm getting an error when a user clicks on the export to excel button while the grid is edit or insert mode. Is there a quick way to address this or do i have to check for the grid's state and disable/enable the button?

I found a workaround for anyone interested:
 
1- wire the ItemCommand, ItemInserted and ItemUpdated events in your grid:
        OnItemCommand="RadGrid1_ItemCommand" OnItemInserted="RadGrid1_ItemInserted" OnItemUpdated="RadGrid1_ItemUpdated"
        
2- Handle the events to prevent excel exporting while the grid does not contain data:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
        {
            if (Session["cancelExcelExport"] == null)
            {
                Session["cancelExcelExport"] = false;
            }
            
            if (e.CommandName == RadGrid.EditCommandName || e.CommandName == RadGrid.InitInsertCommandName)
            {
                Session["cancelExcelExport"] = true;    
            }

            if (e.CommandName == RadGrid.CancelCommandName)
            {
                Session["cancelExcelExport"] = false;
            }

            if (e.CommandName == RadGrid.ExportToExcelCommandName && (bool)Session["cancelExcelExport"] == true)
            {
                e.Canceled = true;
            }
        }
        protected void RadGrid1_ItemInserted(object source, GridInsertedEventArgs e)
        {
            Session["cancelExcelExport"] = false;
        }
        protected void RadGrid1_ItemUpdated(object source, Telerik.Web.UI.GridUpdatedEventArgs e)
        {
            Session["cancelExcelExport"] = false;
        }

Hope this helps someone.
