I would appreciate if anybody help me providing proper information for the given error: 179|error|500|The page is performing an async postback but the ScriptManager.SupportsPartialRendering property is set to false. Ensure that the property is set to true during an async postback.| I have designed a POST request having some parameters including (__ASYNCPOST=true). I got the above error while executing load test.
