Server Code¶

Retrieve Data¶

public class SecurityController : JQGridController
{
    public ActionResult Index()
    {
        return View(new StaffViewModel());
    }

    [HttpGet]
    public JsonResult GetUsersForManager(string sidx, string sord, int page, int rows)
    {
        string currentUserName = HttpContext.User.Identity.Name;
        DataProvider dp = new DataProvider(Common.Common.RequestContext);
        IQueryable<UserResult> results = dp.GetUsersForManager(currentUserName);
        JsonResult result = JQGridResult<UserResult>(results, sidx, sord, page, rows);
        return result;
    }

    [HttpPost, Authorize]
    public JsonResult MaintainUserForManager(UserResult o, FormCollection formData)
    {
        int id;
        DataProvider dp;

        switch (formData["oper"])
