Answer 1

You have to remove the following line:

ddlUserGroup.Items.Insert(0, new ListItem("", "0")); // blank line

So the new code looks like:

private void loadUserGroup()
{
    CUsers objCUsers=new CUsers();
    ddlUserGroup.Items.Clear();
    //ddlUserGroup.Items.Insert(0, new ListItem("", "0"));
    ddlUserGroup.Items.Insert(0, new ListItem("Admin", "2"));
    string suseid= User.Identity.Name;
    int iUserID = Convert.ToInt32(suseid.ToString());
