                        rbpres.Checked = true;
                        rbpres.GroupName = "g1" + increm;

                        RadioButton rbabs = new RadioButton();
                        rbabs.ID = "rbtwo" + increm;
                        rbabs.GroupName = "g1" + increm;
                        tc1.Controls.Add(rbpres);

Hi,

try this code

C#

if (!IsPostBack)
   {
       RadioButton rdn = new RadioButton();
       rdn.ID = "rdbtn";
       rdn.Text = "ghgfh";
       contdiv.Controls.Add(rdn);
   }
   Control d = contdiv.FindControl("rdbtn");

In the above code,you've to use table id for searching radio button control.

instead of contdiv you've to place your table id

All the Best

HOW CAN I GET RUN TIME TABLE ID ON BUTTON CLICK
BUT I TRIED IN THIS WAY
Table tbl = this.Page.FindControl("tbl1") as Table;
IT WONT WORK OUT CAN YOU SHOW ME THE WAY TO GET IT
THANK YOU

you gave table id as runat="server"

in which control you are adding your radio button control

for eg.
you are adding your radio button control in table
then use
tableid.findcontrol("radiobuttonid")

tulasiram3975 3-Oct-11 9:42am

ok i show you whole table
Table tbl = new Table();
tbl.ID = "tbl1";
tbl.Attributes.Add("runat", "server");
tbl.CellSpacing = 0;
tbl.CellPadding = 4;
TableHeaderRow thr = new TableHeaderRow();
TableHeaderCell thc = new TableHeaderCell();
Label lbrolno = new Label();
lbrolno.Text = "Roll No";
thc.Controls.Add(lbrolno);
thr.Cells.Add(thc);
tbl.Controls.Add(thr);
ViewState["nofsub"] = length;
// TableHeaderRow thr1 = new TableHeaderRow();
for (int n = 0; n < length; n++)
{
TableHeaderCell thc1 = new TableHeaderCell();
//thc1.ColumnSpan = 2;
Label lbsubjects = new Label();
lbsubjects.ID = "subject" + n;
lbsubjects.Text = sid.Split(',')[n];
thc1.Controls.Add(lbsubjects);
thr.Cells.Add(thc1);
}
tbl.Controls.Add(thr);
int increm = 0;
while (dr77.Read())
{
TableRow tr = new TableRow();
tr.BorderWidth = 1;
tr.BorderColor = Color.Black;
tr.BorderStyle = BorderStyle.Solid;
TableCell tc = new TableCell();
// tc.RowSpan = 2;
tc.BorderWidth = 1;
tc.BorderColor = Color.Black;
tc.BorderStyle = BorderStyle.Solid;
Label lbrolnocel = new Label();
lbrolnocel.Text = dr77["sno"].ToString();
tc.Controls.Add(lbrolnocel);
tr.Cells.Add(tc);
tbl.Controls.Add(tr);
// TableRow th1 = new TableRow();
for (int n = 0; n < length; n++)
{
TableCell tc1 = new TableHeaderCell();
//tc1.Width = 50;
// TableCell tc2 = new TableHeaderCell();
tc1.BorderWidth = 1;
tc1.BorderColor = Color.Black;
tc1.BorderStyle = BorderStyle.Solid;
RadioButton rbpres = new RadioButton();

rbpres.ID = "rbone" + increm;
rbpres.Checked = true;

rbpres.GroupName = "g1" + increm;

RadioButton rbabs = new RadioButton();
rbabs.ID = "rbtwo" + increm;

rbabs.GroupName = "g1" + increm;
tc1.Controls.Add(rbpres);

tc1.Controls.Add(rbabs);
tr.Cells.Add(tc1);
tr.Cells.Add(tc1);
increm++;
}

tbl.Controls.Add(tr);
}
PlaceHolder1.Controls.Add(tbl);
