POWebmethods in base page, works in one inherited page, not but in a second
text
Body
copied!<p>I am trying to move my common <code>PageMethods</code> to a <code>MyBasePage</code> in which two <code>.aspx</code> pages will inherit. </p> <p>On <code>page1.aspx</code>, I can call the <code>PageMethods.SetFormID("abc")</code> fine.</p> <p>However, on <code>page2.aspx</code>, I get 'PageMethods is undefined' error, when trying to access the same method <code>PageMethods.SetFormID("def");</code></p> <p>Here is my pseudocode:</p> <ol> <li><p><code>MyBasePage</code> inherits from <code>System.Web.UI.Page</code>, and includes the <code>WebMethodAttribute</code>, the method is both static and public.</p> <pre><code> [System.Web.Services.WebMethod] public static void SetFormID(string formID) { //save formID as a session variable; } </code></pre></li> <li><p>Both pages inherit from <code>MyBasePage</code></p> <pre><code>public partial class Page1 : MyBasePage public partial class Page2 : MyBasePage </code></pre></li> <li><p>Both pages include a <code>ScriptManger</code> line with <code>EnablePageMethods="true"</code></p> <pre><code>< asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" EnablePartialRendering="true"/> </code></pre></li> <li><p>From the javascript on each page, I call </p> <pre><code>PageMethods.SetFormID(id); </code></pre></li> <li><p>I transition to <code>Page2.aspx</code>, by calling either: </p> <pre><code>window.open("Page2.aspx"); -or- window.location("Page2.aspx"); </code></pre></li> </ol> <p>Thus, I must have done something wrong with <code>Page2.aspx</code>, so I tried saving <code>Page1.aspx</code> as <code>Page2.aspx</code> (thus, both pages would have identical code, except the class name). Page 1 works as before, but Page 2 fails with <code>PageMethods is undefined</code>.</p> <p>I then tried to set Page2 as the startPage in VS, and have it call Page1. Page 2 can now call the PageMethods fine, but Page1 will fail.</p> <p>Anyone have any ideas on what is happening here? Should I be able to call <code>PageMethods</code> defined in my baseClass from any page derived from it? Maybe it has something to do with how the page is transitioned?</p> <p>PS: it is a VS2012, .NET4 project</p>
