                            // Session["un1"] = txtBox1.Text;

                     tc.Controls.Add(lnkbutton);
            // Add the TableCell to the TableRow
                     tr.Cells.Add(tc);
                     tr.Cells.Add(tc);
                     tr.Cells.Add(tc);

    //    }
        // Add the TableRow to the Table
          tbl.Rows.Add(tr);
          }
         // count++;

            }
        } while (r1.NextResult());


        r1.Close();
        con.Close();
        cmd = null;
        r1 = null;
        con = null;
        //r1.Close();
    }

the table tbl is getting created and the cells tc are also created and the textbox and link buttons is placed in the cells. but while clicking the link button the value in the text box,which is corresponding to linkbutton cell should be assigned to session variable and it should be navigated to other page. for that i need help. plz am in urgency..

But why are you using html table???
use datatable, and grid, bind the grid with datatable, use gridview rowcommand event it is much more easier way to do the thing.....

if you are really want to use html table then have to do some more work....

give "id" to the table and set runat="Server" i.e. make table a server control.

and then Do some necessory changes in following code....

Control ctrl;

Button btn;
foreach(ctrl in tablename.controls(0).controls(0).controls
{
   if (myControl is System.Web.UI.WebControls.Textbox)
            {
               session["value"]= (ctrl as textbox).text;
            }
}
}

but still am not quite sure that it will store correct value
