Hello Nivi,

Have you tried the below one :
newusermodel.User_Type_Id = ddlDropdown.SelectedValue;
Guest User6y ago
its working..basically my problem is in query..

fisrtly i use

ddlDropdown.Items.Insert(0, new System.Web.UI.WebControls.ListItem("Select Option", "0"));

now

ddlDropdown.Items.Insert(0, new System.Web.UI.WebControls.ListItem("Select Option"));

Hi Nivi,

You need to use !IsPostBack in page load. replace your page load code as below
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
      bindUsingEntityFrameWork();
    }
}
and then use this
newusermodel.User_Type_Id = ddlDropdown.SelectedValue;

hi
Nisha Regil
I already bind it...plz Check before ask

You need to write your dropdown bind inside Page_Load event in (!IsPostBack). Otherwise each time the page is loaded the dropdown will rebind iteself. Hence you are not getting the value of selected dropdown,
