I'm modeling my code on this example: http://samples.infragistics.com/2010.3/WebFeatureBrowser/WebDropDown/WebDropDownCascadeClient.aspx

I have three WebDropDown controls: wdd1, wdd2, wdd3.

When wdd1 's selection  changes, I want new values to be cascaded to wdd2 & wdd3. I've tried to code it both server -side and client-side, and neither work. My code for server-side/client-side are the same except for the lines marked "comment-toggle".

Here is my js:

    function wdd1_SelectionChanged(sender, args) {

        // get the selected value of the current WDD (wddPayroleSite)
        value = args.getNewSelection()[0].get_value();
        cascadeWebDropdown(value);

        return;

    }

    function cascadeWebDropdown(value) {

        var wdd2 = $find('<%= wdd2.ClientID %>');
        var wdd3 = $find('<%= wdd3.ClientID %>');

        wdd2.loadItems(value);
        wdd3.loadItems(value); // comment-toggle

    }

Here is my VB.NET:

    Protected Sub wdd2_ItemsRequested(ByVal sender As Object, ByVal e As Infragistics.Web.UI.ListControls.DropDownItemsRequestedEventArgs) Handles wdd2.ItemsRequested

        Dim text As String = CType(e.Value, String)

        Dim id  As Integer = 0

        If (Integer.TryParse(text, id)) Then
            LoadWdd2(id)
            ' LoadWdd3(id) ' comment-toggle
        End If       

    End Sub

End VB.NET Code

LoadWdd2() & LoadWdd3() are functions that perform the databind to their respective WDD controls.

Also, how can I prevent the auto-opening of the child WDD? Going back to the sample, if I select a country, the state WDD opens and focuses automatically. I don't want this to occur.
