Is your radio buttons are dynamically generated?

tulasiram3975 26-Nov-10 6:03am

RadioButton rb = (RadioButton)PlaceHolder1.FindControl(Request.Form["attrad"+i]);
i tried in this way but getting null reference exception sir

Toniyo Jackson 26-Nov-10 6:07am

try this,
RadioButton rb = (RadioButton)PlaceHolder1.FindControl("attrad"+i);

tulasiram3975 26-Nov-10 6:09am

Toniyo Jackson 26-Nov-10 6:12am

tulasiram3975 26-Nov-10 6:17am

for (int i = 0; i < rows; i++)
{
TableRow tr = new TableRow();
for (int j = 0; j < 1; j++)
{
RadioButton attrad = new RadioButton();
attrad.ID = "attrad" + i.ToString();
TableCell tc = new TableCell();
tc2.Controls.Add(attrad);
tr.Cells.Add(tc2);
}
atntab.Controls.Add(tr);
}
PlaceHolder1.Controls.Add(atntab);

for (int i = 0; i < 7; i++)
