Hi,

I have an ASPX page like this:
<head runat="server">  
    <title></title>  
        <script type="text/javascript">  
    function Test() {  
        PageMethods.TestIT();  
        alert("done");  
    }  
</script> 
 
</head> 
 
<body> 
    <form id="form1" runat="server">  
    <div> 
        <telerik:RadScriptManager runat="server" EnablePageMethods="True">  
    </telerik:RadScriptManager> 
 
<button onclick="Test(); return false;">tet</button><br />      
    </div> 
    </form> 
</body> 
</html> 
 
This runs fine.

Now I tried to achive the same thing in a masterpage like this;
<head runat="server">  
    <title></title>  
    <script type="text/javascript">  
    function Test() {  
        PageMethods.TestIT();  
        alert("done");  
    }  
</script> 
 
    <asp:ContentPlaceHolder ID="head" runat="server">  
    </asp:ContentPlaceHolder> 
</head> 
<body> 
    <form id="form1" runat="server">  
        <telerik:RadScriptManager runat="server" EnablePageMethods="True">  
    </telerik:RadScriptManager> 
 
    <div> 
    <button onclick="Test(); return false;">tet</button><br /> 
        <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">  
          
        </asp:ContentPlaceHolder> 
    </div> 
    </form> 
 
This results in "Microsoft JScript runtime error: 'PageMethods' is undefined"

What do I have to change to enable the things in a masterpage?

Regards

Manfred

Follow up:

First of all sorry - this post should have been placed in the Ajax section.
And one more point of precision:
If I place the [WebMethod] on the base class of my pages the things work.

The problem at all is, that when I define the method in the MasterPage code behind no script is emitted for this method call.

Hi ManniAT,

Does this work with the built-in ScriptManager? RadScriptManager does not do anything special with page methods. That capability is inherited from the ScriptManager control.

I guess not (I'm not 100% sure).
And the post is (to be clear) not a kind of "you bad telerik guys made" or something like this :)

It is (regardless of the reason for the problem and not asking who is guilty) just a question if someone knows if there is a way to get PageMethods out of a master pages code behind.

I know you (the telerik guys who make those things) have much more experience with these ajax things than I.
And so my hope was (is) that someone knows the problem - or even has a workaround.
Or that
Anyone can tell me: sorry no chance to get PageMethods from a method in a masterpage.

It is not a stopping issue (I made this working by using a common base class for my content pages which holds the webmethod).
So if someone has an idea - it would be great to learn it - if not don't worry.

Regards

Manfred

Instead of using Telerik's RadScriptManager, please try to use ASP.NET's Script Manager. I have used the following code:
<asp:ScriptManager ID="scrMan1" runat="server" EnablePageMethods="true" />
and I don't get the  "Microsoft JScript runtime error: 'PageMethods' is undefined" error anymore. It should be about something how Telerik handles the ScriptManger I guess.

This works fine for me with Telerik's ScriptManager.  The one anomaly I did notice however is that the PageMethods enumeration will not be created if you are defining your webmethods in a user control that you load server-side.  This limitation also exists with the asp ScriptManager.  So if you need to load User Controls, either define your page webmethods in the base page or as a standard web method in a web service.

Hi Manfred,

I just ran into the same issue and I resolved it by changing the protection level on the WebMethod to public. Seems like the ScriptManager in the Masterpage cannot access the TestIt() method if it is Protected; however, in your first case the scriptmanager could access the protected method since it was in the page itself.

Cheers,
Andrew.
