Almost a year ago Nikhil Kothari claimed that Microsoft was working on addressing the following limitations (see http://forums.asp.net/thread/1150298.aspx):

1.  Sometimes it is desirable to cause a full page postback from within a UpdatePanel.  This is desirable because not everything works inside an UpdatePanel.  (See http://forums.asp.net/thread/1301938.aspx and http://forums.asp.net/thread/1150298.aspx)
   
2. It should be possible to issue a page redirect from within an UpdatePanel (see http://forums.asp.net/1150506/ShowPost.aspx)
   
3. It should be possible to generate an Excel file from within an UpdatePanel (see http://forums.asp.net/thread/1282087.aspx and http://forums.asp.net/thread/1414231.aspx)

Does anyone know what the status of these fixes is?

I think we fixed issue #1, and 2 see sample below. Office 12 has some API that you can plug in the event handler.

Thank you, Andres.   We tried this and issues 1 and 2 are indeed resolved.  To add to the answer, the documentation actually makes reference to this:  http://ajax.asp.net/docs/tutorials/enhancing/updatepanelTriggerEditorDialog.aspx


If anyone knows about how to solve issue number 3, we'll appreciate the feedback.

hello.

i still think that the best option to #3 is to use a handler that returns that file since you still can't get the excel file from within a panel. 

I was earlier using an excellent ajax framework, MagicAjax, for .net 1.1 that allowed me to add an attribute to controls that instructed the framework to override the ajax callback, see http://www.magicajax.net/site/docs/Usage.html#attributes. That is intuitive, as you do not always have easy access to ScriptManager from code (i.e. in user controls).

hello.

getting a reference to the scriptmanager from a user control is as calling the GetCurrent static method of the class:

ScriptManager manager = ScriptManager.GetCurrent( this.Page );

protected void Button1_Click(object sender, EventArgs e)

{

Response.Redirect("http://www.microsoft.com");

}

This solution doesn’t work to me... I need some help with that.. Anyone?

 Thanks.

hello.

does that mean that you're not being redirected? 

Luis Abreu:

hello.

does that mean that you're not being redirected? 

True.

hello again.

that's weird since atlas has supported redirection for a long time. did you update web.config file to use the new release? 

Thank you, Luis!

This just to confirm that by referencing ScriptManager, setting the

manager.RegisterPostBackControl(YourButton) in code beside/behind

allows you to circumvents the callback and cause an actual postback for (dynamically added) controls that do not support ajax, such as File Upload. At least in beta 2.
