Hi,
I have a problem with calling javascript function that will call web service fin ASP.NET AJAX. This is the description:
When i use one page (.aspx) i place a script manager that reference to .asmx web service reference and write javascript code to call that service on client event. (onchange of a dropdownlist).. it works
but when i do the same thing in a content page with the a master page which also have a script manager that refer to the same service, it doesn't work . the page load ok but the ajax functionality does not work, and in the bottom-left corner of the browser there is a warning/error icon when i click it says null is null or not an object in lin1 #100 . There is no line #100 in my content file.aspx
so i viewed source of the browser but doesn't really help me to get what i want
the Javascript to call the webservice is placed between <asp:content> tag in content page .aspx. I have a scriptmanagerpr oxy is content page but does nothing because the service i want is already defined in master page's script manager
Please help me !!!!

Aha got it !,
When using content page, ASP.NET cannot render the actual ClientID of the control, that's why when i tried to get a hold on it by using $get("ddl"); , .NET does not properly render it to match the actual client id (the client id of the rendered control have some prefix on it), so just use $get( '<#ddl.ClientID >' );
and it works like a charm
