Hi,

I downloaded the sample application that the Microsoft video
ASPNETAJAXForWinMobile described but it doesn't work on my Windows Mobile 6
emulator. After enabling the script error reporting of the mobile IE, it pops
up several JScript error and the ajax behavior is not funtional at all.
Where can I look for any possible issue?

Thanks.

Daniel
 
Hi Daniel,

Are you using the following code?
http://download.microsoft.com/download/2/c/9/2c94e6e4-478c-4853-92b0-2a7f6c4
b6b60/CS-Devices-AspNetAjaxForWinMobile_cs.zip

I've tested it on my side. It works fine. When you run it in IE can you see
the JS errors?

If it still doesn't work please tell me the error description.

Thanks Allen,

It's still not working properly at my side. Most of the time, selecting the
items in the combo box doesn't produce any feedback in the upper lable and
sometimes after clicking the button, it pops up with error
Line 5 Character:9340
Error: '__EVENTTARGET is null or not an object
Source:(null)
Please help investigate. Thanks!

Hi Daniel,

Thanks for the information. To investigate this issue, firstly, could you
confirm that you're using the same code as mine?

Sometimes when the server is busy we need to wait several seconds to see
the update of the page. Could you double check it to make sure there's no
update?

Does it happen only when using the emulator? When you use IE to view the
page will you see the same error?

Hi Allen,

Yes, I'm using the exact same bit of code as your url.
Sometime the label does get updated but most of the time, no response for at
least dozens of seconds.
I only have the enulator and the error doesn't happen all the time. Looks
like after I have clicked other controls then come to the button, the error
comes.
In desktop IE, everything works fine.

Many thanks.

Daniel
 
Hi Daniel,

Thanks for the clarification. However, I spent couple of hours trying to
repro it on my side but could not see the behavior as you described. My
environment is:

" Windows XP SP2 (one machine as the server and running the Windows Mobile
Emulator)
" IIS 5.1
" ASP.NET 2.0.50727
" Tested on both Windows Mobile 6 Standard Emulator and Windows Mobile 6
Professional Emulator

Could you provide your environment so that I can try to set up the same one
to repro?

Allen Chen

Hi Allen,

I'm working on the same environment as yours except I'm SP3. After attaching
Visual Studio to the ASPNET working process, I found that sometimes the
client click will not trigger the server code. It looks like the client
postback doesn't occur or doesn't make to the server side.

Thanks.

Daniel

Hello,

I get the same error message

"Line 5 Character:9340
Error: '__EVENTTARGET is null or not an object
Source:(null)"

with

Microsoft Device Emulator, Windows Mobile 6.1.

Server: .NET Framework 3.5 SP1

I hadn't this error with .NET Framework 2.0. Therefore I conclude that
ASP.NET AJAX has changed from version 2.0 to 3.5 SP1 and now this error
occurs with IEMobile.

I seems that sometimes no Ajax calls are send to the server on button clicks
or dropdown onchange events respective that the callback is not computed and
the partial page rendering is not performed.
