I have two dropdown list in one page.
when i select one value from first dropdown,value in second dropdown comes according to selected value in first dropdown.
But problem is ,when i click on submit button ,if i have select anything from second dropdown,it takes first value and insert it. this is somthing like..page load problem when i click on submit.
but i cant understand what is actually problem.
here is my code.
first dropdown is set to autopostback=true.

C#

int Userid;

objdal.Deptid = Convert.ToInt16(ddlName.SelectedValue);
objdal.Name = ddlName.SelectedItem.Text;
                
dv = objdal.AssignTimetable_SelectDeptid(); //select userid from userinfo where deptid=@deptid AND name=@name
Userid = Convert.ToInt16(dv.Table.Rows[0]["Userid"].ToString());

here userid is always comming of first value from second dropdown.

C#

protected void Page_Load(object sender, EventArgs e)
    {

        if (!IsPostBack)
        {
            SqlDataAdapter ad = new SqlDataAdapter("select Fname,id from x",con);
            DataTable dt = new DataTable();
            ad.Fill(dt);
            if(dt.Rows.Count>0)
            {
                uxCountry.DataSource=dt;
                uxCountry.DataTextField = "Fname";
                uxCountry.DataTextField = "id";
                uxCountry.DataBind();
            }
        }
    }
    protected void uxCountry_SelectedIndexChanged(object sender, EventArgs e)
    {
        uxStates.Items.Clear();
        SqlDataAdapter ad = new SqlDataAdapter("select Lname,yid from y where xid=" + uxCountry.Items[uxCountry.SelectedIndex].Value, con);
         DataTable dt = new DataTable();
        ad.Fill(dt);
        if (dt.Rows.Count > 0)
        {
            uxStates.DataSource = dt;
            uxStates.DataTextField = "Lname";
            uxStates.DataTextField = "yid";
            uxStates.DataBind();
        }
    }

I tried this to filled the two dropdown Country and its states,it works well for me while postback on submit.
