My action accepts a model that looks like the following:
public class ClassListVM
{
public ClassListVM()
{
Filter = new ClassFilterModel();
}
public ClassFilterModel Filter { get; set; }
public PagedList<Class> Classes { get; set; }
}
public class ClassFilterModel
{
public int? TermId { get; set; }
public int? SubFormId { get; set; }
public int? FormId { get; set; }
}
public ActionResult Index(ClassListVM model)
{
model.Classes = classService.GetClasses(model.Filter);
return View(model);
}
Now I want to generate a url like this: /Classes?Filter.SubFormId=1. How do I get the Filter part into the url using this code:
go
As you can see, Filter cannot be used here.
Theoretically, you can build it this way:
go
Something like that; essentially, embed the query string into the client markup, and inject in only the parameters.

I'm trying to implement server-side paging and sorting for jquery-datatable.
but the issue is I'm not able to bind data posted by datatable to my action model
to do sort and filter
Here is the data posted by jquery-datatable ajax request
draw:5
columns[0][data]:FirstName
columns[0][name]:FirstName
columns[0][searchable]:true
columns[0][orderable]:true
columns[0][search][value]:
columns[0][search][regex]:false
columns[1][data]:LastName
columns[1][name]:LastName
columns[1][searchable]:true
columns[1][orderable]:true
columns[1][search][value]:
columns[1][search][regex]:false
......
columns[n][data]:Position
columns[n][name]:Position
columns[n][searchable]:true
columns[n][orderable]:true
columns[n][search][value]:
columns[n][search][regex]:false
order[0][column]:1
order[0][dir]:desc
start:0
length:10
search[value]:
search[regex]:false
and my action method is:
public JsonResult GetGridData(GridFilter filter)
{ ....}
and my model classes are
public class GridFilter
{
public int draw { get; set; }
public List<ColModel> columns { get; set; }
public List<Order> order { get; set; }
public int start {get;set;}
public int length {get;set;}
public search search { get; set; }
}
public class ColModel
{
public string data { get; set; }
public string name { get; set; }
public string searchable { get; set; }
public string orderable { get; set; }
}
public class Order
{
public string dir { get; set; }
public string column { get; set; }
}
public class search
{
public string value {get;set;}
public string regex {get;set;}
}
How can I make data bind properly using default mvc model binders are a custom one.
Thanks
Make sure your model properties have the same data types as defined here.
Also you have gone one level too far with your models.They are sent as individual parameters so you don't need the GridFilter model, they should be received like so:
[HttpPost]
public JsonResult GetGridData(List<ColModel> columns, List<Order> order, Search search, int? start, int? length, int? draw)
{
}
I'm making a simple website where I'm storing some information that I get from an excel file into my models class and retrieving them from the html page. The following class is a class in my models:
public class ToxinInformation
{
public string cas_rn { get; set; }
public string critical_effect { get; set; }
public string point_of_departure { get; set; }
public string adi_tdi { get; set; }
public string intake { get; set; }
public string hazard_quotient { get; set; }
public string comment { get; set; }
public string tox_link { get; set; }
public string tox_link_decription { get; set; }
public string intake_link { get; set; }
public string intake_link_description { get; set; }
public IList<string> Links { get; set; }
}
And I use this code to set the information in my controller class and return the view:
(of course I would set information all the variables, not only the first one)
var model = new ToxinInformation
{
cas_rn = "lol"
};
return View(model);
So far I can easily set all my strings and my list and retrieve them on my html page, but what do I do if in some cases I need several instances of the class "ToxinInformation"? In some cases I have 2 or more set of data I'd like to save and show in HTML except for just one.
Any suggestions would be very helpful.
You should make a list and add instances of model to the list. Then you can use a DisplayFor or EditorFor template to show them all.
var models = new List<ToxinInformation>();
foreach(var dataBlob in YourDataStore)
{
var model = new ToxinInformation()
{
cas_rn = dataBlob.cas_rn // Not sure where your raw data is coming from.
}
models.add(model)
}
return View(models);
Is there a way in MVC to pass information from one controller to another? I have a character model that looks like this:
public class Character
{
[Key]
public string CharacterID { get; set; }
public string UserID { get; set; }
public string Name { get; set; }
public int Str { get; set; }
public int Con { get; set; }
public int Dex { get; set; }
public int Int { get; set; }
public int Wis { get; set; }
public int Cha { get; set; }
public int BaseAttack { get; set; }
}
And a separate weapon model like this:
public class Weapons
{
[Key]
public string WeaponID { get; set; }
public string UserID { get; set; }
public string CharacterID { get; set; }
public string Name { get; set; }
public string Type { get; set; }
public string Range { get; set; }
public int Damage { get; set; }
public int Crit { get; set; }
public int CritMultiplier { get; set; }
public string Hands { get; set; }
public string Distance { get; set; }
}
To create a weapon, you first need to create a character which assigned an ID, and I want to be able to pass that ID into the create method of my weapon controller. Is there a way to do this? Thanks
You can use TempData for this purpose. TempData stores data only between two requests. When you set the TempData the next request that is initiated can retrieve value from the TempData and it will be erased for any consequent requests.
[HttPost]
public ActionResult CreateCharacter()
{
// creates charaeters here and sets the tempdata
TempData['CharacterId'] = 50;
return RedirectToAction('CreateWeapon');
}
[HttpGet]
public ActionResult CreateWeapon()
{
var weaponModel = new WeaponModel() { CharacterId = (int)TempData['CharacterId'] };
return View(weaponModel);
}
and in your view simply have a hidden for the CharacterId, so it will be persisted if you your post fails validation or if you need to re-display the view.
#Html.HiddenFor(e => e.CharacterId);
Again this is just one approach, only if you you don't want to pass the CharacterId in the url.
You can also achive this just by passing it in the url:
[HttPost]
public ActionResult CreateCharacter()
{
// creates charaeters here and sets the tempdata
return RedirectToAction('CreateWeapon', new { characterId = 50 });
}
[HttpGet]
public ActionResult CreateWeapon(int characterId)
{
var weaponModel = new WeaponModel() { CharacterId = characterId };
return View(weaponModel);
}
I would be inclined to pass the character id to the create weapon action via routing, either as a route token that forms part of the path or via the query string. Be sure to check that the weapon can logically be associated with the character to whom the id corresponds.
You could also pass the id using TempData or Session, but considering both by default will take up memory on the web server, the simple option is to use the routing. In addition, unless you call TempData.Keep("key") after accessing TempData, the value will be removed from TempData after the first access, potentially causing issues if the user refreshes the browser window.
You could use RedirectToAction(), though as titled this will cause browser redirection.
return RedirectToAction("CreateWeapon", "Weapon", new { id = yourid });
or
#Html.ActionLink("CreateWeapon", "Create", new { id = yourid })
Edit: Your plain object property names and your action method variables need to match, to do this.
Hope someone can help - this has been bugging me for around 2 hours - its probably something simple :)
Kendo UI Grid sends a request to my controller
http://localhost:1418/user/update?UserID=1&UserName=Admin&RoleName=Admin&Email=c.j.hannon%40gmail.com&Active=true&Company%5BCompanyID%5D=1&Company%5BCompanyName%5D=asd
However, the controller class 'Company' isnt bound by the binder? Can any one help my view model and controller action signature are below:
[HttpGet]
public JsonResult Update(UserViewModel model)
{
svcUser.UpdateUser(new UpdateUserRequest() {
UserID=model.UserID,
RoleID = model.RoleName,
Email = model.Email,
Active = model.Active.GetValueOrDefault(false),
UserName = model.UserName
});
return Json("", JsonRequestBehavior.AllowGet);
}
public class UserViewModel
{
public int UserID { get; set; }
public string UserName { get; set; }
public string RoleName { get; set; }
public string Email { get; set; }
public bool? Active { get; set; }
public CompanyViewModel Company { get; set; }
}
Cheers

A few things. Your immediate problem is that Company is mapped to a complex object not a primitive type. Kendo Grid just does not do this (as of this writing). Just guessing, but you probably want to setup a foreign key binding on the Grid and just pass back the Id of the company from a listbox. This is not as bad as you think and it will immediatly fix your problem and look nice too.
Maybe personal taste but seems to be a convention. Use the suffix ViewModel for the model that is bound to your View and just the suffix Model for your business objects. So a Kendo Grid is always populated with a Model.
Ex.:
public class UserModel
{
public int UserID { get; set; }
public string UserName { get; set; }
public string RoleName { get; set; }
public string Email { get; set; }
public bool? Active { get; set; }
public int CompanyID { get; set; }
}
public class CompanyModel
{
public int ID { get; set; }
public string Name { get; set; }
}
public class UserViewModel
{
public UserModel UserModel { get; set; }
public IList<CompanyModel> Companies { get; set; }
}
public ActionResult UserEdit(string id)
{
var model = new UserViewModel();
model.UserModel = load...
model.Companies = load list...
return View(model);
}
#model UserViewModel
...
column.ForeignKey(fk => fk.CompanyId, Model.Companies, "ID", "Name")
(Razor Notation)
BUT! This is just an example, you are better off Ajax loading the Grid with the IList becuase I assume you have many Users in the Grid at once, though you could server bind off the ViewModel with a List too. But the list of Companies is probably the same every time, so map it to the View just liek this rather than Ajax load it every time you do a row edit. (not always true)
I have a domain model:
public class Project
{
[Key]
public int ProjectID { get; set; }
public string Title { get; set; }
public string Slug { get; set; }
public string Content { get; set; }
public string Category { get; set; }
public string Client { get; set; }
public int Year { get; set; }
}
I have a view model (which is a portion of the above model):
public class ListProjectsViewModel
{
public IEnumerable<ProjectStuff> SomeProjects { get; set; }
public class ProjectStuff
{
public int ProjectID { get; set; }
public string Title { get; set; }
public string Slug { get; set; }
public string Content { get; set; }
}
// Some other stuff will come here
}
I have an action controller:
public ActionResult List()
{
// Get a list of projects of type IEnumerable<Project>
var model = m_ProjectBusiness.GetProjects();
// Prepare a view model from the above domain entity
var viewModel = Mapper.Map..........
return View(viewModel);
}
How can I code the mapping '........' with automapper ?
Thanks.
There are two steps.
1) Define a mapping with AutoMapper (this is usually done in some sort of bootstrapper called by Global.asax, etc.)
// since all of your properties in Project match the names of the properties
// in ProjectStuff you don't have to do anything else here
Mapper.CreateMap<Project, ListProjectsViewModel.ProjectStuff>();
2) Map the object in your controller:
// Get a list of projects of type IEnumerable<Project>
var projects = m_ProjectBusiness.GetProjects();
// Prepare a view model from the above domain entity
var viewModel = new ListProjectsViewModel
{
SomeProjects = Mapper.Map<IEnumerable<Project>, IEnumerable<ListProjectsViewModel.ProjectStuff>>(projects)
};
return View(viewModel);
The thing to note here is that you are defining a mapping between Project and ProjectStuff. What you are trying to map is a list of Projects (IEnumerable) to a list of ProjectStuff (IEnumerable). AutoMapper can do this automatically by putting that in the generic arguments as I did above. Your View Model that your view is using is wrapping your list of ProjectStuff, so I just create a new ListProjectsViewModel and do the mapping inside of that.
