问题 I want to be able to read values of HtmlHiddenField controls from the Request.Form collection in a user control on postback. The keys in the collection seem to represent the control's name attribute rather than ID.

But how can I do the same with the name attribute? The HtmlHiddenField.Name property doesn't match the key name in Reqest

问题 .NET 4 broke ValidateRequest=“false” for some reason. The solution is -- just put <httpRuntime requestValidationMode="2.0" /> into your web.config file.
