Asp.net Ajex not working.
Hi all,
I am new in Asp.net Ajex. I am trying to use Ajex in my project but it doesnot working as I expected.
When i click on the button to change text of label, it refresh whole page not only label control.
my asp.net code:
HTML Code:
asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:TextBox ID="txt" runat="server">
</asp:TextBox>
<asp:Label ID="lbl" runat="server">
</asp:Label>
<asp:Button ID="btn" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
Re: Asp.net Ajex not working.
Hey,
Is that the only code that you have on your page? Or do you have any other markup on the screen?
Which version of Visual Studio are you using? If you are using Visual Studio 2005 have you added the necessary references to the AJAX Extensions?
Have a look at the following videos which should give you some tips:

Hope that helps!!

Yes, I did watch sample Video on Asp.net web site. I also pratice with that too and it was successed.
The project that is not working did not show any error on the page.
The problem is only, when i click on button it refresh a whole page not only control in update panel.
Anyway, I used VS 2008.
Re: Asp.net Ajex not working.
That's surprising. I took your HTML code and the page doesn't do a full postback. Here is the code
Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ForumTest.aspx.vb" Inherits="ForumTest" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:TextBox ID="txt" runat="server" Width="20em">
</asp:TextBox>
<asp:Label ID="lbl" runat="server">
</asp:Label>
<asp:Button ID="btn" runat="server" Text="Click Me!" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
And code behind
Code:
Partial Class ForumTest
Inherits System.Web.UI.Page
Protected Sub OnClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn.Click
txt.Text = "Updated time:" + DateTime.Now()
End Sub
End Class
Re: Asp.net Ajex not working.
Is this a brand new project or an existing project to which you are adding this page?

Yes, it is. the same code but new project and it works. I think because of configuration. But I cannot find what's wrong in my configuration file. Because when I did a comparison line by line with work project, it is the same.
Re: Asp.net Ajex not working.
Hey all,
I found what is the solution.
Because XHTMLConformance mode set to "Legacy".
