Hi again its me,

here create table is called in page load to to create header row first, and GetAnswers(i) method will call AddRow(s1,s2) method to display the values from database in table, in new row. when i refresh the page, table is disappearing. please help me to overcome it.

public void CreateTable()
{
tbl = new Table();
tbl.BorderColor = System.Drawing.Color.Black;
PlaceHolder1.Controls.Add(tbl);

TableRow tr = new TableRow();
tr.BackColor = System.Drawing.Color.Orange;
tr.ID = "row0";
TableCell tc1 = new TableCell();
TableCell tc2 = new TableCell();
//creating lable
System.Web.UI.WebControls.Label lable1 = new System.Web.UI.WebControls.Label();
System.Web.UI.WebControls.Label lable2 = new System.Web.UI.WebControls.Label();
lable1.Text = "Questions";
lable1.BackColor = System.Drawing.Color.Orange;
lable2.Text = "Answers";
lable2.BackColor = System.Drawing.Color.Orange;
// Add the control to the TableCell
tc1.Controls.Add(lable1);
tc2.Controls.Add(lable2);
// Add the TableCell to the TableRow
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
// Add the TableRow to the Table
tbl.Rows.Add(tr);

}

public void AddRow(string s1,string[] s2)
{
TableRow tr = new TableRow();
tr.ID = "row" + Rows.ToString();
TableCell tc1 = new TableCell();
tc1.ID = "tc1" + Rows.ToString();
TableCell tc2 = new TableCell();
tc2.ID = "tc2" + Rows.ToString();
//creating dropdown list
DropDownList ddl = new DropDownList();
ddl.ID = "list" + Rows.ToString();
ddl.Items.Add("Select Answer");
for (int i = 0; i < s2.Length; i++)
{
ddl.Items.Add(s2[i]);
}
ddl.SelectedIndexChanged += new EventHandler(dl_SelectedIndexChanged);
ddl.AutoPostBack = true;
ddl.EnableViewState = true;
//creating lable
System.Web.UI.WebControls.Label lable1 = new System.Web.UI.WebControls.Label();
lable1.Text = s1;
lable1.ID = "lable" + Rows.ToString();
// Add the control to the TableCell
tc1.Controls.Add(lable1);
tc2.Controls.Add(ddl);
// Add the TableCell to the TableRow
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
// Add the TableRow to the Table
tbl.Rows.Add(tr);
}

protected void dl_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddl9 = (DropDownList)sender;

int quesid = 0;
string questxt = "";
int ansid = 0;
string anstxt = ddl9.SelectedItem.Text;
DataRow[] dr = dt4.Select("anstxt='" + anstxt + "'");
foreach (DataRow row in dr)
{
quesid = Convert.ToInt32(row["quesid"]);
ansid = Convert.ToInt32(row["ansid"]);
questxt = row["questxt"].ToString();
//questxt=row[
}
dt3.Rows.Add(quesid, questxt, ansid, anstxt);
foreach (DataRow row in dt2.Rows)
if (Convert.ToInt32(row["quesid"]) == quesid)
row["son"] = "s";
//ListBox1.Items.Add("Ans: " + anstxt);
//TextBox1.Text = "";
//DropDownList1.Items.Clear();
foreach (DataRow row in dt1.Rows)
{
if (Convert.ToInt32(row["ansid"]) == ansid)
{
row["status"] = 1;
//MessageBox.Show("row status changed to" + row["status"].ToString());
}
}

ViewState["CECdt1"] = dt1;
ViewState["CECdt3"] = dt3;
int i = GetQuestion(dt1, dt2);
GetAnswers(i);
ViewState["CECtbl"] = PlaceHolder1;

}
