I tried to use CascadingDropDown control开发者_如何学C on a sharepoint visual webpart including the project as a web service. Of course it didn´t work as i expected. Has anyone used this control in a sharepoint webpart or knows how to implement a cascading drop down using Ajax ?
I would post up the links to the forum threads at least for my own personal reference.

thanks for your answer i will review that approach to, but well. . what a did wrong was write inside the update panel a form tag
<asp:UpdatePanel ID="AjaxSampleUpdatePanel" runat="server">
<ContentTemplate>
<form></form>
</ContentTemplate>
</asp:UpdatePanel>
but that was making the problem so i just change the form tag ubication like this
<form>
<asp:UpdatePanel ID="AjaxSampleUpdatePanel" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</form>
and that make the code works!!
