How to cache mvc3 webgrid results (so that col sort click doesn't?

Question

Can somebody please tell me how I can cache my webgrid results so that when I sort by column it doesn\'t re-run my stored procedure query every time?

When clicking

Well inside the controller action which is invoking the method on your repository supposed to query the database you could check whether the cache already contains the results.

Here's a commonly used pattern:

public ActionResult Foo()
{
    // Try fetching the results from the cache
    var results = HttpContext.Cache["results"] as IEnumerable<MyViewModel>;
    if (results == null)
    {
        // the results were not found in the cache => invoke the expensive 
        // operation to fetch them
        results = _repository.GetResults();

        // store the results into the cache so that on subsequent calls on this action
        // the expensive operation would not be called
        HttpContext.Cache["results"] = results;
    }

    // return the results to the view for displaying
    return View(results);
}
