    I have a telerik DDL like so:



    <telerik:RadDropDownList ID="rddlNames" runat="server" DataSourceID="NamesDataSource" DataTextField="Name" DataValueField="ID" OnSelectedIndexChanged="rddlNames_SelectedIndexChanged" OnDataBound="rddlNames_DataBound" AutoPostBack="True" CausesValidation="false"></telerik:RadDropDownList>

    protected void rddlNames_SelectedIndexChanged(object sender, Telerik.Web.UI.DropDownListEventArgs e)
                radTileList.Visible = true;
                radTileK.NavigateUrl = "KSignOut.aspx?DC=" + rddlNames.SelectedItem.Text;
                radTileT.NavigateUrl = "TSignOut.aspx?DC=" + rddlNames.SelectedItem.Text;
                radTileManageT.NavigateUrl = "ManageT.aspx?DC=" + rddlNames.SelectedItem.Text;
                radTileManageK.NavigateUrl = "ManageK.aspx?DC=" + rddlNames.SelectedItem.Text;
                radTileManageR.NavigateUrl = "ManageR.aspx?DC=" + rddlNames.SelectedItem.Text;
            protected void rddlNames_DataBound(object sender, EventArgs e)
                rddl.Items.Insert(0,new Telerik.Web.UI.DropDownListItem("---"));
                    rddlNames.Items[0].Enabled = false;// Attributes.Add("disabled", "disabled");
                rddlNames.Items[0].Selected = true;


     There is one major issue with it in that the selectedIndexChanged doesn't trigger when navigating to the root of the website i.e. http://locahost:1234

    But if I navigate to http://localhost:1234/Default it works fine.

    This is causing huge confusion among the users which keep reporting the website as not working.


    Please suggest a fix for this as it is quite urgent.


    Thank you.

    Hello Silviu,

    I am not quite sure that I had fully understood the scenario, where you had encountered the issue. How do you navigate to the root of the website? Where the is the RadDropDownList located in your project? Please elaborate a bit more on the experienced problem.
