Hi all:

I have a web form that has a login button, and then 2 drop downs and the
action I need is thus:

Login button is click, user is logged in and the first drop-down list is
populated
When the user makes a selection from the first drop-down list, the 2nd
drop-down list is populated
When the user makes a selection from the 2nd drop-down list, the record
corresponding to that selection is displayed.

All seems to work fine until I make a selection from the 2nd drop-down, then
I am getting an error:

Sys.Webforms.PageRequestManagerParserErrorException: The message received
from the server could not be parsed. Common causes for this error are when
the response is modified by calls to Response.Write(), response filters,
HttpModules, or server trace is enabled. Details: Error parsing near
'ue,true,true,true]}|<script language='ja"

I have no idea what that means!

Could this error be caused by the multiple-postbacks from the login and then
the population and selections from the drop-downs?

Can anyone make a suggestion as to how to fix this, or a better idea than 2
drop-downs?

Thanks all.

John.

which throws the above exception...

However, at first glance, it looks like you're trying to write out
JavaScript using Response.Write(). If so, then that's easily fixed...

Hi Mark:

Thanks for your reply, again! :)

The code is a bit long and includes lots of calls to the CRM web services,
but I have pasted relevant parts below. I am not calling an JScript at all,
so I am not sure where that error is coming from.

The formatting of the code you posted went a bit wild at the end, and
I couldn't read it properly...

The error you posted is raised by the ASP.NET Ajax library. I suspect
that your drop down list boxes are in an update panel, but that
somewhere in your page you're injecting javascript (either directly,
or by using a control which is injecting javascript). The
ScriptManager object (which you must have on your page somewhere) has
a number of methods which can be used to inject javascript into the
page in a way that is compatible with the update panel.

Hi:

Yes you're right. The drop-downs are actually on a TabPanel inside a
TabContainer, which is in an Update panel...

Any suggestions to attack this?

John.

I would start with a tool such as http://www.fiddler2.com/fiddler2/.

It alllows to see the content of each http request. In this case it should
allow to have a full view of the unwanted content, allowing to find more
easily where the unwanted content comes from...

If you are looking for cascading dropdowns instead of using updatepanels I
would recommend using those provided by the ASP.NET Ajax Control Toolkit :
http://www.asp.net/ajax/ajaxcontroltoolkit/samples/CascadingDropDown/CascadingDropDown.aspx
