Hi all

I am having following code..

#region Dynamically added control to the table <br />
            TableRow tr=null;<br />
            int cols = 0;<br />
            if (multiFile.Files.Length > 0)<br />
            {<br />
                msg.InnerText = "These Files Uploaded Successfully. [" + multiFile.Files.Length + " files]. ";<br />
                int counter=0;<br />
                foreach (UploadedFile file in multiFile.Files)<br />
                {<br />
                    //this for display 5 image in one row <br />
                    if (cols % 5 == 0)<br />
                    {<br />
                        tr = new TableRow();<br />
                    }<br />
                    string FolderPath = Server.MapPath("Images");<br />
                    file.MoveTo(FolderPath + "\\" + file.FileName, MoveToOptions.Overwrite);<br />
<br />
                    Image myImage = new Image();<br />
                    myImage.ImageUrl = "~/Images/" + file.FileName;<br />
                    myImage.Height = 150;<br />
                    myImage.Width =150;<br />
                    //create new inner table so that we can add all fields in sequence<br />
                    Table innerTable = new Table();<br />
                    <br />

                    innerTc11.Controls.Add(myImage);<br />

<br />
                    //create column 2 for row 2 <br />
                    TableCell innerTc22 = new TableCell();<br />
                    innerTc22.Controls.Add(ddlEyePart);<br />
<br />
                    //add both columns to the 2nd row<br />
                    innerTr2.Controls.Add(innerTc21);<br />
                    innerTr2.Controls.Add(innerTc22);<br />
<br />
                    //now add both rows in the table. <br />
                    innerTable.Controls.Add(innerTr1);<br />
                    innerTable.Controls.Add(innerTr2);<br />
<br />
                    //now finaly add inner table to the upper column<br />
                    TableCell tc = new TableCell();<br />
                    tc.Controls.Add(innerTable);<br />
<br />
                    tr.Controls.Add(tc);<br />
<br />
                    if (cols % 5 == 0)<br />
                    {<br />
                        tblUploaded.Rows.Add(tr);<br />
                    }<br />
<br />
                    cols++;<br />
                }<br />
                <br />
            }<br />
