hi everybody, I'm having an issue with hiding an animation during the excel export option of the ultrawebgrid. I'm able to display an animation when the user clicks on a link button to export the excel spreadsheet via the client side. Howerver, right after the export, the animation still appears and I can't make it disappear. If anybody could help me, I would greatly appreciate it. Thank you so much.

protected void lbExcelExport_Click(object sender, EventArgs e)

    {

        //ShowReport();

        Infragistics.WebUI.UltraWebGrid.UltraWebGrid uwgGrid = null;

        switch (_reportNumber)

        {

            case 1:

                //Workbook wb = new Workbook();

                //Worksheet ws = wb.Worksheets.Add(ddReport.SelectedItem.Text);

                //if (chart.Visible)

                //{

                //    WorksheetImage wsi = new WorksheetImage(System.Drawing.Image.FromFile(MapPath(_chartImagePath)));

                //    wsi.TopLeftCornerCell = ws.Rows[0].Cells[0];

                //    wsi.BottomRightCornerCell = ws.Rows[2].Cells[5];

                //    wsi.PositioningMode = ShapePositioningMode.DontMoveOrSizeWithCells;

                //    ws.Shapes.Add(wsi);                  

                //}

                uwgExcelExport.ExportMode = Infragistics.WebUI.UltraWebGrid.ExcelExport.ExportMode.Custom;

                uwgGrid = rSummary.GetGrid;

                uwgExcelExport.Export(uwgGrid);//, ws, 10, 0);               

                break;

            case 2:

                uwgGrid = details.GetGrid;

                uwgExcelExport.Export(uwgGrid);

                break;

            case 4:

                uwgGrid = rSummary.GetGrid;

                uwgExcelExport.Export(uwgGrid);

                break;          

        }

    

        //myAnimatedImage1.Visible = false;

    }

        e.CurrentWorksheet.Columns[0].Width = 15000;
        e.CurrentWorksheet.Columns[0].CellFormat.WrapText = ExcelDefaultableBoolean.True;
