Can I create Web Access Ajax Custom Control?

Question

Our Project has Tow Cutom Fields (A, B)  with DropDownList.
And these fields display data from DataBase.
When A is changed, call webservice and get DB data and B DropDownList is filled with DB Data.
But I add changed event in A control, When event fire, raised PostBack so MessageBox is showed.
So I want create two DropDownList controls in Ajax Update Panel.
Is it possible? Plz, give me some advise.

Hi Park,

I modified " C:\Program Files\Microsoft Visual Studio 2008 Team System Web Access\Web\UI\Pages\WorkItems\WorkItemEdit.aspx" like following code

    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <dbz:EditWorkItem ID="we" runat="server" />
        </ContentTemplate>
    </asp:UpdatePanel><br/><br/><br/><br/>

and it seems that it work well.

In addition, I think using Ajax WebService is a better way .

Best Regards,
Ruiz
