I am implementing an ASP.NET MVC 5 web app using ASP.NET Identity 2 and Troy Goode's PagedList . I need to display UserRole data in the following format in a JqGrid:
User Name | Role Name
This is my UserRole class:
public class UserRole : Microsoft.AspNet.Identity.EntityFramework.IdentityUserRole<int>
{
[ForeignKey("UserId")]
public virtual User User { get; set; }
[ForeignKey("RoleId")]
public virtual Role Role { get; set; }
}
This is my repository method
public virtual IQueryable<UserRole> GetAsQueryable(Expression<Func<UserRole, bool>> where)
{
return _dataContext.UserRoles.Where(where).AsQueryable();
}
This my Controller method (the GetAsPagedList method simply orders the input list, applies PagedList's .ToPagedList method to it and returns a subset of it):
public ActionResult GridData(MvcJqGrid.GridSettings gridSettings)
{
IQueryable<UserRole> items = _repository.GetAsQueryable();
IPagedList<T> pagedOrderedItems = PagingHelper<UserRole>.GetAsPagedList(
items,
gridSettings.SortOrder, gridSettings.SortColumn,
gridSettings.PageIndex, gridSettings.PageSize);
var jsonData = new
{
total = pagedOrderedItems.TotalItemCount / gridSettings.PageSize + 1,
page = gridSettings.PageIndex,
records = pagedOrderedItems.TotalItemCount,
rows = (
from c in pagedOrderedItems
select new
{
id = c.UserId + '-' + c.RoleId,
cell = new[]
{
"Edit",
"Details",
// TODO: something like this:
// [UserName] = c.User.UserName
// [RoleName] = c.Role.Name
c.Role.Name
}
}).ToArray()
};
return Json(jsonData, JsonRequestBehavior.AllowGet);
}
I can'.t figure out where and how I should deep load data from the tables linked through foreign keys to my table (IE Users.UserName and Roles.Name) - could you please help?
_dataContext.UserRoles.Include("Role").Include("User").Where(where).AsQueryable();
