asp.net / c# / ajax

I am using aspx/c#/Ajax/AjaxToolKit for the project.
For some reasons, the ajax fresh thing only works when it is first load on the webpage.
later when i tried again. I still see the refresh thing back from the auto post back event.
Any reasons why?

<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" enablepartialrendering="false" runat="server"></cc1:ToolkitScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div>
asdfasdfasdfdf
</div>
</ContentTemplate>

No <triggers> defined in your code sample and no postback controls showing in your <contenttemplate> so...?

Any control that causes a postback on your page that is not either inside your <contenttemplate> or setup as a <triggers> is going to cause your page to postback normally(non ajax).

i don't know much about ajax. can you show me how to put those correctly in masterpage?

Thanks,

Nope, but if you post your masterpage with your updatepanel and other relavent code I can take a look at it.

<asp:UpdatePanel ID="UpdatePnll1" runat="server"></asp> will be on each children page?

Member_2_4913559

It really depends.

I know you are trying to understand and that's commendable but where and how to place this control depends entirely on the context in which you want to use it and the controls you use it with.

I could give you a general answer but you'd be confused. I could give you a specific answer but then it wouldn't work because your situation would be something I didnt know about.

This is something you really need to read up on, test with and then when you have an error you can ask more.

You could try this which may make ajax work on all your pages, but I'm not promising there won't be complications. I just can't know.

<see code>

In this example on the Masterpage I have surrounded the content placeholder (which contains all aspx pages) with an update panel. Now technically any page inside of it that tries to cause a postback will actually trigger an ajax postback.

If you had more than one content placeholder on your masterpage you would have to expand the update panel to surround them all.
