问题 As I understand it you can tell the IE8 (and I assume later versions) how to best render your page. This is useful because the page may have been designed for IE7, quirks mode or to target IE8 standards mode.

With this default the user could change the rendering mode by clicking on the "Compatibility View" button next to the refresh button.

The first method succeeds and always returns a valid JSON object when the asmx web service method is decorated with [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)] .

问题 I am currently learning .net and have come to a brick wall with trying to implement url rounting.

问题 I've got a page with several controls, such as Checkboxlists and two containers holding search results. I've been told to make this site persistent, so the user can come back from anywhere while browsing our site and find it's settings restored (read: boxes stll checked; results still available) So far I have tried to override SavePageStateToPersistenceMedium and LoadPageStateFromPersitenceMedium, but I am constantly running into a yellow screen of death as soon, as I click a button on the
