Hi,
I binded data to a DropDownList at run time code as follows:

C#

cmd = new SqlCommand("select RoleName from Roles where Active=1", con);
con.Open();
da = new SqlDataAdapter (cmd);
da.Fill (ds);
DropDownList1.DataSource = ds;
DropDownList1.DataTextField = ds.Tables[0].Columns[0].ToString ();
DropDownList1.DataBind();
con.Close();

At runtime i am trying to find SelectedIndex and SelectedItem, it showing index is 0(Zero) always eventhough actual index is not 0(Zero), SelectedItem also same that first Item only showing rather then actual Item.
Please explain the reason for this and give me needful advise to get currect this.

Thanks in advance

Try to load the dropdown if it is not postback

C#

if(!IsPostBack)
{
cmd = new SqlCommand("select RoleName from Roles where Active=1", con);
con.Open();
da = new SqlDataAdapter (cmd);
da.Fill (ds);
DropDownList1.DataSource = ds;
DropDownList1.DataTextField = ds.Tables[0].Columns[0].ToString ();
DropDownList1.DataBind();
con.Close();

}

Solution 2

Make sure that you have written the Binding code inside the if(!IsPostBack).
