Thank u for your help

here is my code(display method,next button and previous button actions)


////////////////////////DISPLAY METHOD///////////////////////////////
public void display()
{

DataRow dr=t.Rows[n];

Label3.Text=dr["q"].ToString();
RadioButtonList1.Items[0].Text = dr["a1"].ToString();
RadioButtonList1.Items[1].Text = dr["a2"].ToString();
RadioButtonList1.Items[2].Text = dr["a3"].ToString();
RadioButtonList1.Items[3].Text = dr["a4"].ToString();
Label4.Text = dr["c_ans"].ToString();
int index;
if (Session["selected"] != null)
{
index = RadioButtonList1.Items.IndexOf(RadioButtonList1.Items.FindByText(selected));
}
else
{
index = RadioButtonList1.Items.IndexOf(RadioButtonList1.Items.FindByText(dr["s_ans"].ToString()));
}
Response.Write(index);
RadioButtonList1.Items[index].Selected = true;

}

////////////////////////NEXT METHOD///////////////////////////////
protected void Button2_Click(object sender, EventArgs e)
{
try
{
Button1.Enabled = true;
Label4.Visible = false;

n = n + 1;
// selected = (string)Session["selected"];
string sql = "update questions set s_ans='" + selected + "' where q='" + Label3.Text + "'";
Response.Write(sql);
comm = new SqlCommand(sql, conn);
int x = comm.ExecuteNonQuery();

if (n >= t.Rows.Count - 1)
{

Button2.Enabled = false;
}
Session["selected"] = selected;
RadioButtonList1.SelectedIndex = -1;

Session["n"] = n;
display();

}
catch (Exception ex)
{
Label4.Visible = true;
Label4.Text = "Please Choose an answer "+ex.Message;
}
}

////////////////////////prev METHOD///////////////////////////////
protected void Button1_Click(object sender, EventArgs e)
{try
{

Button2.Enabled = true;
Label4.Visible = false;
// selected = (string)Session["selected"];
n = n - 1;
if (n == 0)
{
//n = 0;
Button1.Enabled = false;
}
string sql = "update questions set s_ans='" + selected + "' where q='" + Label3.Text + "'";
Response.Write(sql);
comm = new SqlCommand(sql, conn);
int x = comm.ExecuteNonQuery();

Session["selected"] = selected;
RadioButtonList1.SelectedIndex = -1;

Session["n"] = n;
display();



}
catch (Exception ex)
{
Label4.Visible = true;
Label4.Text = "Please Choose an answer "+ex.Message;
}
