How to decode viewstate

I've got a fairly complex page I'm working on, with lots of usercontrols, repeaters, etc.

The ViewState on that page has ballooned up to over 4MB, which is causing a "Maximum Request Length Exceeded" error on postback. The temporary fix would be to increase the maxRequestLength attribute in HttpRuntime, but that isn't fixing the root problem.

Is anybody aware of how could I inspect/query the ViewSt开发者_C百科ate to see which controls are the biggest offenders? What I'd like to try and avoid is spending a bunch of time optimizing a control that would only give me a couple kB in savings, while there are others on the page that could be stashing several hundred kB in ViewState

Thanks!

You can use:

• Fiddler Web debugging tool
• Enable Trace for particular page: <%@ Page Language="c#" Trace="true"%>
• Enable Trace for whole Application in web.config so each page will show a lot of useful trace info at the bottom

<configuration>
  <system.web>
    <trace enabled="true" pageOutput="false" localOnly="false"/>
  </system.web>
</configuration>

Helpful Trace indicators (in your case) are:

• Render Size bytes
• ViewState Size bytes
• ControlState Size bytes
