Facing issue in jquery in Asp.net MVc application

[vnr]

Hi, I am working on an Asp.net MVc web application.In my application on dropdown change i am submiting form (calling a controller method), and in controller method I am assigning value to a Tempdata .From that controller, call will be redicted to aspx page where I will access that tempdata (which is assigned in the controller).Here I am facing the problem as my Tempdata value is coming as empty but If I keep an alert in jquery or debug the application I am able to get the tempdata value.So not able to understand what exactly is the problem?Can anyone please help me on this? tried putting Tempdata.keep() also but did nt work. Thanks, Vanita
