Ajax - Master Pages - ScriptManager - Web User Controls

[=?Utf-8?B?TGFycnkgRXBu?=]

I have an app using Ajax. The scriptmanager is within the form that is
within the master page. I also have web user controls that are doing partial
rendering and are "borrowing" or "inheriting" the scriptmanager from the
master page. Heck, when they're rendered, the scriptmanager is on all the
pages and it works.
However, in the VS2005 designer, I constantly see "Can't render image"
errors, and it's nearly impossible to effectively use the WYSIWYG designer
with those errors.

Is there some way to increase the intelligence of the contained objects so
they know that THERE IS a scriptmanager control on the page, but that it's in
the master page?

Thanks,
Larry

Hi Larry,

I cannot seem to reproduce the issue you're experiencing. This is probably
because I'm only testing with a simple UpdatePanel and some basic server
controls. If you could elaborate more about your master page and content
page, I can verify that again on my side.

However, please note that since AJAX is just released recently and even our
latest SP1 of VS2005 doesn't have much support for the AJAX. We plan to add
full support for AJAX in next version of Visual Studio -- code named Orcas.
Therefore, we might see currently VS2005 has some limitations here
regarding AJAX designer.

Regarding the intellisense related to Master Pages, there's one directive
might help you here: in your content page, you could use the directive "<%
@ MasterType" to explicitly let the designer know which exact master page
the content page is using, and then the "Master" property of the page will
point to the strong-typed master page class:

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" Title="Untitled
Page" %>
<%@ MasterType VirtualPath="~/MasterPage.master" %>
...
Hope this helps.
