I have an idea. On the Users page, we don't have Paging like we do on the Comments page. So all 300 users are being retrieved and displayed at one time - rather than 10 or 20 users at a time if we had paging. The data from the server comes
in JSON format, and there's a default limit to how big the JSON size from the server can be.
Fortunately, this limit can be easily increased. To do so requires modifying the web.config file. Coincidentally, the area to modify is the same area you were having problems with last week
here. It's the <system.web.extensions> section in the web.config file that needs to be modified. Hopefully you were able to go with solution # 1 from that thread.
We need to add a <system.web.extensions> section into the web.config file. If you went with solution # 1, then that means you already have a <system.web.extensions> section in your web.config file. Here's what the final <system.web.extensions>
section should look like:
<authenticationService enabled="true" requireSSL="false"/>
I added the <jsonSerialization> tag in there.
Although you already have it, for reference,
here is the SQL CE 4.0 web.config file that comes with BE 2.0 RC. It has the <system.web.extensions> section in there.
Not entirely sure if this is the solution to the problem, but seems likely.
