Hi, I'm using AjaxControlToolkit in a personal module, ok, this works fine.

I added <%@ Register Assembly="AjaxControlToolkit"....%> and <ajaxToolKit:ToolkitScripManager...../> to my Defalut.aspx, and the module works perfectly.

It's works perfectly in all browser, including IE, but...IE show me one error:

Mensaje: Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once.

I been reading about this, and I think that the problem is that DNN use his own scriptmanager, DNN adds this line to Default.aspx

And I think that this is the problems. I  readed about edit DNN proyect and rebuilt...but I can't (and I don't like) do this....some idea??

 Thanks, best regards.

Remove your script manager so you are relying on the Telerik one already in place and check to ensure your module still works.

DNN includes a very good Ajax Calendar from Telerik (TSM = Telerik Script Manager). To use that in your module, do something like this [I have added a space after the < to get the code to show here]

< %@ Register TagPrefix="dnnweb" Namespace="DotNetNuke.Web.UI.WebControls" Assembly="DotNetNuke.Web" %>
< div class="dnnFormItem">
< dnn:Label ID="transdatelabel" runat="server" Text="Transaction Date " AssociatedControlID="TransDatePicker" HelpText="Today's date is assigned automatically - you can change it" />
< dnnweb:DnnDatePicker runat="server" CssClass="dnnFormInput" Culture="en-US" ID="TransDatePicker" />
