WebDropDown loses items after postback
posted

I've a problem with a WebDropDown with NetAdvantage 11.2.

I'm binding a DataTable to a WebDropDown, setting the ItemTemplate as shown in the demo video by Craig Shoemaker:

<ig:WebDropDown runat="server" ID="cboTest" TextField="Code" ValueField="Code" AutoPostBackFlags-ValueChanged="On" EnableViewState="true">

     <ItemTemplate>

         <%# DataBinder.Eval(Container.DataItem, "Code")%>: <%# DataBinder.Eval(Container.DataItem, "Description")%>

            </ItemTemplate>

</ig:WebDropDown>

In the code behind the dropdown is populated in the OnClick event of a button:
Protected Sub btnNewElement_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnNewElement.Click
    Me.cboTest.DataSource = dtArticles
    Me.cboTest.DataBind()
    Session(" dtArticles") = dtArticles
End Sub
The problem is that, when I choose an element from dropdown and postback occurs:
- if I use only the code shown above, the selected item is correctly chosen (CurrentValue has the expected value), but when I open the dropdown afted a ValueChanged postback all the elements are blank. Note: items in the dropdown are still there and I can select any other item, text and value are correctly set, but I can't see what item I'm clicking on...
- if I add a rebind (set DataSource from the session object and call DataBind()) in the Page_Load event, after the postback all the items are correctly shown, but the CurrentValue is always Nothing and the selected item (== the text shown in the dropdown) is always set as the first element of the dropdown.
Enabling or disabling ViewState of the dropdown doesn't seem to change things.
Any hint?
