I mean to say Total 8 column in the Datagrid. In that 3 are visible (1,2,8) rest are in hidden(3,4,5,6,7) in datagrid. And the 8th is the Image Column Now if I Export datagrid using Excel exporter And i used following code to export image in to Excel.

if (e.GridRow.Cells.Exists("Result Icon"))
            {
                int icolumn = e.GridRow.Cells.IndexOf("Result Icon");
                // The values in this cell are byte arrays representing images.
                // In order to export them, we need to convert the byte array into an Image.
                // The EmbeddableImageRenderer on the column will do this for us.
                Image image = this.GetImageRendererImage(e.GridRow, e.GridRow.Band.Columns["Result Icon"]);

                // Create a WorksheetImage
                WorksheetImage worksheetImage = new WorksheetImage(image);

                // We will want to maintain the aspect ratio of the image so it looks the
                // same as it does in the grid cell. So determine the available size in the excel
                // worksheet. We do this by creating a region contain all three Excel cells, then
                // getting the bounds.
                WorksheetRegion worksheetRegion = new WorksheetRegion(e.CurrentWorksheet, e.CurrentRowIndex - 1, icolumn, e.CurrentRowIndex - 1, icolumn);
                Rectangle availableRect = worksheetRegion.GetBoundsInTwips();

                // Set the bounds of the image. This method automatically fits the image into the
                // bounds and maintains the image aspect ratio. Note that the aspect ratio may be
                // slightly off due to some differences between the units used for width in
                // different versions of Excel.
                worksheetImage.SetBoundsInTwips(e.CurrentWorksheet, availableRect, true);

                // Add the image into the workbook
                e.CurrentWorksheet.Shapes.Add(worksheetImage);

                // Remove the text from the cell.               
                e.CurrentWorksheet.Rows[e.CurrentRowIndex - 1].Cells[icolumn].Value = null;
            }

 In this case Image is coming in excel sheet but its coming to wrong place. I hope now you got the problem.
