  Hello All,

  I am using Visual Studio 2010, and developing a web project. My requirement is to add controls to web page dynamically. I have added the controls and those are displaying properly on the web page.

  But when I am trying to read values from the controls, I am unable to find the controls.

  Below is the sample code.

  int i;
  TableCell tcSNum;
  i = 0;
  foreach (DataRow drStudent in dsStudent.Tables[0].Rows)
  {
  tr = new TableRow();
  tr.BorderColor = System.Drawing.Color.Blue;
  tcSNum = new TableCell();
  tcSNum.ID = "TCNUM" + i.ToString();
  lblSName = new Label();
  lblSName.ID = "LBLSNAME" + i.ToString();
  lblSName.Text = drStudent["StudentName"].ToString();
  tcSNum.Controls.Add(lblSNum);
  tr.Cells.Add(tcSNum);
  t.Rows.Add(tr);
  i++;
  }
  this.pnl.Controls.Add(t);
  
  Below code to find controls in the Panel
  
  for(int i = 0;i<numberofStudents;i++)
  {
  Label lblrno = (Label)pnl.FindControl("LBLSNAME" + i.ToString());
  Response.Write(lblrno.Text);
  }
  
  

  
  

  Please help me in this regard.

  Thanks in advance
