Troubles with calling a PageMethod from javascript [solved]

Add Command Buttons in grid.

On RowDeleting event trap the id or any thing by which you can execute delete query. execute query and again bind grid.

I've been struggling with the same problem for a few days now without getting anywhere. In my aspx page I try to call a PageMethod from a javascript and then inserting the result of that call into a div.

MyPage.aspx

XML

<ajaxToolkit:ToolkitScriptManager runat="server" ID="ScriptManager1" EnablePageMethods="true">
   <Scripts>
      <asp:ScriptReference Path="~/javascript/myscript.js" />
   </Scripts>
</ajaxToolkit:ToolkitScriptManager>
...
...
<a href="javascript:myFunction();">Click to run script</a>
...
...
<div id='theDiv'></div>

MyPage.aspx.cs

[System.Web.Services.WebMethod]
public static string ReturnTheString()
{
   return "This is the string returned";
}

And finally my javascript function where everything goes wrong myscript.js

JavaScript

function myFunction()
{
   PageMethods.ReturnTheString(OnSucceeded, OnFailed);
}

function OnSucceeded(result)
{
   var myDiv = document.getElementById('theDiv');
   myDiv.innerHTML = result;
}

function OnFailed(error)
{
   alert(error.get_message());
}

The problem is that I don't get the expexted "This is the string returned" as result in my OnSucceeded js function. And when I debug my website and set up a breakpoint in ReturnTheString() the code never runs.. My result parameter is sometimes just empty and sometimes has the value of almost my whole page (starting with

Today I finally found what was the cause of this behaviour - and fixed it. It turned out I was missing the following lines in my

web.config file:<br />
<pre lang="csharp">
<httpModules>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</httpModules>
</pre><br />
<br />
Hopefully this might help someone else who gets stuck with this problem :)

cause of these errors?

What's the cause of the car not driving?

It's hard to tell what's causing your problems without additional information. Can you reproduce the errors? Are you logging the complete exceptions? You should, as they contain the information on the origin of the exception, usually pointing to a particular place in your code.

quiz.aspx.cs code is:

 <br />
<br />
protected void Button1_Click1(object sender, EventArgs e)<br />
    {<br />
       <br />
<br />
        // Save off previous answers<br />
        System.Data.DataRowView dr = (System.Data.DataRowView)DetailsView1.DataItem;<br />
<br />
        // Create Answer object to save values<br />
        Answer a = new Answer();<br />
        a.QuestionID = dr["QuestionID"].ToString();<br />
        a.CorrectAnswer = dr["CorrectAnswer"].ToString();<br />
<br />
        if (RadioButton1.Checked == true)<br />
        {<br />
            crropt = "option1";<br />
        }<br />
        else if (RadioButton2.Checked == true)<br />
        {<br />
            crropt = "option2";<br />
        }<br />
        else if (RadioButton3.Checked == true)<br />
        {<br />
            crropt = "option3";<br />
        }<br />
        else if (RadioButton4.Checked == true)<br />
        {<br />
            crropt = "option4";<br />
        }<br />
        a.UserAnswer = crropt;<br />
<br />
        ArrayList al = (ArrayList)Session["AnswerList"];<br />
        al.Add(a);<br />
<br />
        Session.Add("AnswerList", al);<br />
<br />
        if (DetailsView1.PageIndex == DetailsView1.PageCount - 1)<br />
        {<br />
            // Go to evaluate answers<br />
            Response.Redirect("evaluate.aspx");<br />
        }<br />
        else<br />
        {<br />
            DetailsView1.PageIndex++;<br />
            Button1.Text = "Finished";<br />
        }<br />

Have you included the namespace that includes the Answer class here?
That is what is throwing this compile error.
