I want to use ASP.NET Ajax toolkit, in my DNN modules. I installed ASP.NET Ajax extensions, and then put the AjaxControlToolkit.dll in the "Bin" folder.

Then, I used Ajax's TabControl on my module's View control. I get an error saying "There cannot be more than 1 instance of ToolkitScriptManager on a Page".

However, in my Control, I only have one instance of ToolkitScriptManager. Removing that instance does not render the TabControl on the page, but there is no error either.

Can you tell me precise steps for using Ajax Toolkit with DNN???

DNN handles the injection of script managers so that you avoid the issue of having multiple modules putting the control on the page multiple times.  In your control's Init event, call DotNetNuke.Framework.AJAX.RegisterScriptManager to get a script manager put on the page for you.

Hope that helps,

I am using the following markup to get a TabPanel inside my control:

<ajax:TabContainer runat="server" ID="tabContainer" Height="138px" ActiveTabIndex="0">
    <ajax:TabPanel runat="server" ID="Panel1" HeaderText="Signature and Bio">
        <ContentTemplate>
            <asp:UpdatePanel ID="updatePanel1" runat="server">
                <ContentTemplate>
                    <table>
                        <tr>
                            <td>
                                Signature:</td>
                            <td>
                                <asp:TextBox ID="signatureText" runat="server" /></td>
                        </tr>
                        <tr>
                            <td>
                                Bio:</td>
                            <td>
                                <asp:TextBox ID="bioText" runat="server" /></td>
                        </tr>
                    </table>
                    <asp:Button ID="Button3" runat="Server" Text="Save" />
                    <br /><br />
                    Hit Save to cause a postback from an update panel inside the tab panel.<br />
                </ContentTemplate>
            </asp:UpdatePanel>
        </ContentTemplate>
    </ajax:TabPanel>

    <ajax:TabPanel runat="server" ID="Panel3" HeaderText="Email" >
        <ContentTemplate>
            Email: <asp:TextBox ID="emailText" runat="server" />
            <br /><br />
            <asp:Button ID="Button1" runat="server" Text="Save" />
            <br /><br />
            Hit Save to cause a full postback.
        </ContentTemplate>
    </ajax:TabPanel>

    <ajax:TabPanel runat="server" ID="Panel2" HeaderText="Controls">
        <ContentTemplate>
            <div>Controls authored by Toolkit User (read-only - demo purposes):</div>
            <ul>
                <li>Calendar</li>
                <li>MaskedEdit</li>
                <li>Accordion</li>
                <li>Calendar</li>
                <li>Calendar</li>
            </ul>
            <br />
        </ContentTemplate>
    </ajax:TabPanel>
</ajax:TabContainer>

Everything else is fine, just that the headers of the control are not being rendered properly, as shown below:

 

What could be the possible reason???

This looks like your site might not be using an XHTML doctype.  The AJAX Control Toolkit requires XHTML doctypes to render correctly.  We have an article in our support wiki on how to do that here: www.engagemodules.com/Modules/EngagePublish/PublishDocumentation/tabid/66/Default.aspx.

Hope it helps,
