So I'm trying to include some Telerik controls on a page which already is using a lot of controls from the AJAX Control Toolkit.  Telerik's controls require a RadScriptManager.  I was previously using the ToolkitScriptManager for my ScriptManager object on the page... When I switch to RadScriptManager, I get the following error:

AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.

...And of course I can't use more than one ScriptManager on the page.  How do I reconcile this?

Hi Jesse,

Are you using the ASP.NET 4.0 version of the Telerik.Web.UI assembly? Assuming that you are using RadControls Q1 2010, the DLL version should look like this:

2010.1.309.40   (not 20 or 35)

If needed, you can use RadScriptManager to register a Javascript file manually by adding asp:ScriptReferences manually as nested properties.

My web host is not yet supporting ASP.NET 4.0 framework, so I'm stuck on ASP.NET 3.5 for the time being.

If I understand correctly what you're suggesting, you're saying to use a RadScriptManager object on my page (in this case, my Master Page) and then manually including asp:ScriptReferences to the files required by the AJAX Control Toolkit.  Is this correct?

Hello Jesse,

The exception you receive indicates that you are using the .NET 4 version of the AJAX toolkit with our controls. There is a separate version of the AJAX toolkit for .NET 3.5 which you should install in case you build your applications under .NET 3.5. It should work without issues with RadScriptManager and you do not need to register script references manually using its ScriptReferences collection.

In case you are interested in the compatibility of our controls with the NET 4 toolkit, please refer to this forum thread.

Kind regards,
Sebastian

Hello,

I am also having the same issue. I have tired with:
  • ToolkitScriptManager, but then the Telerik controls don't work.
  • RadScriptManager, then AjaxControlToolkit controls don't work
  • asp:ScriptManager - Neither works

I am using Telerik.Web.UI, Version=2010.1.519.35 for .NET 3.5 and  AjaxControlToolkit, Version 3.5.40412.0

Any help would be appreciated,

Thanks

Hello Mike,

What exception do you get with the .NET 35 version of RadControls for ASP.NET AJAX and the NET 35 AJAX toolkit? The error discussed in the beginning of this thread is concerning dependency from the .NET 4 AJAX toolkit scripts and should not be relevant for the .NET 35 version.

Go to your master page(or main page if you do not have one) and delete the 'radscriptmanager' from that page. Then drag a new toolkitscriptmanager from the ajax controls in the toolbox (that you created during installation). Things seem to wroking fine here with the latest build of toolkit 3.5

Cheers

Hi,

I'm happy to announce that the next internal build (available later today) will be fully compatible with the ACT for .NET 4.0 sites. Read this forum post for more more details.

We don't have a solution for .NET 3.5 sites apart from loading the scripts externally. This is also described in the forum post.

I hope this helps.

Sincerely yours,

First of first check your Telerik version, it should be equal or greater  (2010.1.309.35)
If your version is less then update your telerik and install your system. then open your visual studio project , when you open then telerik automatically ask to you for update your vesrion in your existing Project.

then remove radscriptmanager from Master pages. and only add 

<

 

 

asp:ToolkitScriptManager ID="ToolkitScriptManagerMaster" runat="server">

 

 

</asp:ToolkitScriptManager>

its working very smoothly.

I have an Update Panel on  my master page, and an ajax toolkit scriptmanager, i also have an update panel containing a label which indicates the status of any action performed..... On one of my subpages i have a radgrid which has a button that should trigger an update in the masterpage update panel hence update the status... this works fine before publishing, but fails after been published

Hi Ogunseye,

Please have a look into the following sample code which works fine at my end.

Master Page ASPX:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:Label ID="Label1" runat="server">
        </asp:Label>
    </ContentTemplate>
</asp:UpdatePanel>

Content Page ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateEditColumn="true">
    <MasterTableView>
        <Columns>
            <telerik:GridTemplateColumn>
                <EditItemTemplate>
                    <telerik:RadButton ID="RadButton1" runat="server" Text="Set Status" OnClick="RadButton1_Click">
                    </telerik:RadButton>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Content Page C#:
protected void RadButton1_Click(object sender, EventArgs e)
{
    Label lbl = (Label)this.Master.FindControl("UpdatePanel1").FindControl("Label1");
    lbl.Text = "Update Panel Label Fired";
}

Thanks,
Shinu.
