Using system.linq.lookup values for dropdownfor mvc 4 - asp.net-mvc-4

In MVC 4 I am using razor to get items from collection and assign it to a var. The var is of type
{System.Linq.Lookup<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>.Grouping}
This is my code
var ChairList = Model.Interviewers.Where(d => d.LocKey == Convert.ToString(location.LocationKey) && d.IsChair && d.Date == date.Date).GroupBy(x => new { x.FullDetails, x.InterviewerId, x.Preference }).ToList();
And how it looks in watch:
- ChairList Count = 1 System.Collections.Generic.List<System.Linq.IGrouping<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>>
- [0] {System.Linq.Lookup<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>.Grouping} System.Linq.IGrouping<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer> {System.Linq.Lookup<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>.Grouping}
+ [System.Linq.Lookup<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>.Grouping] {System.Linq.Lookup<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>.Grouping} System.Linq.Lookup<<>f__AnonymousType0<string,System.Guid,string>,IMEModels.InterviewManagement.Interviewer>.Grouping
- Key { FullDetails = "TEST - Richard Jackson - (80020937)", InterviewerId = {ff1efad7-7176-4fab-a1bb-30f6656c8880}, Preference = "Available" } <Anonymous Type>
FullDetails "TEST - Richard Jackson - (80020937)" string
+ InterviewerId {ff1efad7-7176-4fab-a1bb-30f6656c8880} System.Guid
Preference "Available" string
+ Raw View
I want to use this for a dropdownfor but it doesn't recognise the key and value that I am giving for it:
#Html.DropDownListFor(m => m.InterviewSchedules[location.InterviewDates.IndexOf(date)].ChairId, new SelectList(ChairList, "InterviewerId", "FullDetails"))
Can someone help me with this piece of code? It's possible that there is an easier way of doing this that I am unaware of.

For view
#Html.DropDownListFor(m => m.InterviewSchedules[location.InterviewDates.IndexOf(date)].ChairId,, ViewData["ReturnList"] as SelectList, new { #class = "form-control" })
For Code (Return as viewData)
public SelectList ReturnList(Guid UID) {
var ChairList = Model.Interviewers.Where(d => d.LocKey == Convert.ToString(location.LocationKey) && d.IsChair && d.Date == date.Date).GroupBy(x => new { x.FullDetails, x.InterviewerId, x.Preference }).ToList();
List<SelectListItem> selectItems = ChairList.Select(s => new SelectListItem() {
Text =FullDetails,
Value = InterviewerId.ToString(),
Selected = false
}
).ToList();
selectItems.Insert(0, new SelectListItem() {
Text = " --Select -- ",
Value = null,
Selected = false
});
SelectList selectList = new SelectList(selectItems, "Value", "Text");
return selectList;
}

Data not binding to Kendo dropdown list in mvc4

Data is not binding to Kendo dropdown list list is returning form my method
My dropdown
#(Html.Kendo().DropDownListFor(model => model.ParentAssetID)
.OptionLabel(" ")
.Name("ParentAssetID")
.DataTextField("AssetName")
.DataValueField("AssetId")
.SelectedIndex(0)
.Text(string.Empty)
.DataSource(source =>
{
source.Read(read =>
{
read.Url("../Asset/GetAllAssetsByCompanyId");
});
}))
my Action Result
public IEnumerable<AssetDetails> GetAllAssetsByCompanyId()
{
IList<AssetDetails> _assetSearchlist;
using (var client = new HttpClient())
{
AssetRepository assetrep = new AssetRepository();
Guid cp = new Guid(Session["CurrentCompanyId"].ToString());
_assetSearchlist = assetrep.GetAllAssetsByCompanyId(cp, "", "", "");
return _assetSearchlist;
}
}
public JsonResult GetOpportunityListByAccount(string Id)
{
Guid ID = new Guid(Id);
List<OpportunityViewModel> cpvm = new List<OpportunityViewModel>();
List<CrmOpportunity> crmOppList = new List<CrmOpportunity>();
cpvm = srv.OpportunitySet.Where(z => z.CustomerId.Id == ID).ToList();
foreach (var crm in cpvm )
{
CrmOpportunity crmOpp = new CrmOpportunity();
crmOpp.Id = crm.Id;
crmOpp.Name = crm.Name;
crmOppList.Add(crmOpp);
}
return Json(crmOppList, JsonRequestBehavior.AllowGet);
}
#(Html.Kendo().DropDownListFor(x => x.FromOpportunity)
.Name("OpportunityDDL")
.DataTextField("Name")
.DataValueField("Id")
.DataSource(source => {
source.Read(read =>
{
read.Action("GetOpportunityListByAccount", "CrmIntegration");
})
. ServerFiltering(true);
})
.HtmlAttributes( new { style = "margin-left:13px; width: 275px;" })
)
Data access is a little truncated but this is what you'll need to do
#(Html.Kendo().DropDownListFor(model => model.ParentAssetID)
.OptionLabel(" ")
.Name("ParentAssetID")
.DataTextField("AssetName")
.DataValueField("AssetId")
.SelectedIndex(0)
.Text(string.Empty)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("GetAllAssetsByCompanyId", "Asset");
});
}))
Only a minor change but have you tried read.Action? Also is maybe try removing the following;
DropDownListFor(model => model.ParentAssetID)
and replace with
DropDownListFor<ClassName>()
Only a thought.

Html.DropDownListFor will ignore ViewBag values

I have the following action method:-
public ActionResult AdvanceSearch(string AssetTypeName)
{
ViewBag.Techtypes = repository.GetAllTechnologyType().ToList();
ViewBag.AssetID = repository.GetTechnologyTypeID(AssetTypeName);
return View();
}
which will call the folloiwng view :-
//code goes here
#Html.DropDownListFor(model =>model.AssetTypeID, ((IEnumerable<TMS.Models.TechnologyType>)ViewBag.Techtypes).Select(option => new SelectListItem {
Text = (option == null ? "None" :option.Name),
Value = option.AssetTypeID.ToString(),
Selected = (Model != null) && (option.AssetTypeID == ViewBag.AssetID)
}), "All")
//code goes here
but the drop down will always show the default value"All" , instead of selecting the item that match the viewBag value option.AssetTypeID == ViewBag.AssetID. baring in ming that the ViewBag will have the correct value. can anyone adice what might be the problem ?
Thanks
I think your condition is wrong. Try this. Check the 'Selected' property.
#Html.DropDownListFor(model => model.AssetTypeID, ((IEnumerable<TechnologyType>)ViewBag.Techtypes).Select(option => new SelectListItem
{
Text = (option == null ? "None" : option.Name),
Value = option.AssetTypeID.ToString(),
Selected = (option.AssetTypeID == (int)ViewBag.AssetID)
}), "All")

sample of kendo combo for relation table with id and value

i'm using kendo ui in my asp.net mvc 4 with razor views and encounter problem with kendo combo when the list load from an action via ajax with sending parameters to the server like the sample here:HERE
becuase the table has more then 2,000 rows.
when i load the edit page, the combo load and filter the data as expected, but the value of this field is - [object object].
i did declare the .DataTextField("ProffName") + .DataValueField("ID")
My ClientsController:
public ActionResult Edit(int id = 0)
{
Clients clients = db.Clients.Find(id);
if (clients == null)
{
return HttpNotFound();
}
ViewData["MyAgency"] = new SelectList(db.Agency, "ID", "AgentName", clients.AgencyId);
ViewData["MyCategory1"] = new SelectList(db.CategoryTbl, "ID", "category", clients.CategoryId);
List<SelectListItem> obj = new List<SelectListItem>();
obj.Add(new SelectListItem { Text = "male", Value = "1" });
obj.Add(new SelectListItem { Text = "female", Value = "2" });
obj.Add(new SelectListItem { Text = "choose", Value = "0" });
ViewData["MyMin"] = obj;
ViewBag.ProffID = new SelectList(db.ProfTBL, "ID", "ProffName", clients.ProffID);
ViewBag.Metapel = new SelectList(db.Workers, "ID", "WorkerName", clients.Metapel);
return View(clients);
}
My ProffController:
public ActionResult ProffVM_Read(string text)
{
var Proff_Tbl = db.ProfTBL.Select(proff => new ProffVm { ID = proff.ID, ProffName = proff.ProffName });
if (!string.IsNullOrEmpty(text))
{
Proff_Tbl = Proff_Tbl.Where(p => p.ProffName.Contains(text));
}
return Json(Proff_Tbl, JsonRequestBehavior.AllowGet);
}
and the Kendo combo:
#Html.Label("Proff")
#(Html.Kendo().ComboBoxFor(model => model.ProffID)
.Name("proffCbo")
.DataTextField("ProffName")
.DataValueField("ID")
.Events(e => e
.Select("proffCbo_select")
.Change("proffCbo_change")
)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("ProffVM_Read", "Proff")
.Data("onAdditionalData");
});
})
)
where am i wrong ???
i can change this combo to textbox but... i have to realize the magic.
Thanks
Change these two lines
var Proff_Tbl = db.ProfTBL.Select(proff => new ProffVm { ID = proff.ID, ProffName = proff.ProffName });
Proff_Tbl = Proff_Tbl.Where(p => p.ProffName.Contains(text));
to
var Proff_Tbl = db.ProfTBL.Select(proff => new ProffVm { ID = proff.ID, ProffName = proff.ProffName }).ToList();
Proff_Tbl = Proff_Tbl.Where(p => p.ProffName.Contains(text)).ToList();

Dropdowns not rendered when override object.cshtml MVC4

My actual problem was mentioned here.
Hide property of model in dynamic view
To solve the problem, I have overrided object.cshtml as mentioned in the answer.
However, when I did this, the dropdowns that I am rendering using UIHints are not working.
In place of dropdown, just False, False False (the no.of Falses are equal to number of list items I have in my viewdata) are displayed.
I am not sure what is happening here, can somebody advise what is going on?
in my controller:
ViewData["PartyRoleTypeId"] = (IEnumerable<SelectListItem>)PartyRoleTypeRepo.All()
.ToList()
.Select(p => new SelectListItem { Value = p.PartyRoleTypeId.ToString(), Text = p.Caption, Selected = p.PartyRoleTypeId == obj.PartyRoleTypeId });
ViewData["PartyId"] = (IEnumerable<SelectListItem>)PartyRepo.All()
.ToList()
.Select(p => new SelectListItem { Value = p.PartyId.ToString(), Text = p.Organization.Caption, Selected = p.PartyId == obj.PartyId });
My dropdown edit template in shared/editortemplates/DropDownList.cshtml
#{
var fieldName = ViewData.ModelMetadata.PropertyName;
}
#Html.DropDownList("",(IEnumerable<SelectListItem>)ViewData[fieldName], "Choose..." , new { #class ="combo"})
object.cshtml
#functions
{
bool ShouldShow (ModelMetadata metadata)
{
return metadata.ShowForEdit
&& metadata.ModelType != typeof(System.Data.EntityState)
&& !metadata.IsComplexType
&& !ViewData.TemplateInfo.Visited(metadata);
}
}
#if (ViewData.TemplateInfo.TemplateDepth > 1)
{
if (Model == null)
{
#ViewData.ModelMetadata.NullDisplayText
}
else
{
#ViewData.ModelMetadata.SimpleDisplayText
}
}
else
{
//ViewData.Clear();
foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm => ShouldShow(pm)))
{
if (prop.HideSurroundingHtml)
{
#Html.Editor(prop.PropertyName)
}
else if (prop.DisplayName == "Id")
{
<div></div>
}
else if (!string.IsNullOrEmpty(Html.Label(prop.PropertyName).ToHtmlString()))
{
<div class="editor-label">#Html.Label(prop.PropertyName)</div>
}
<div class="editor-field">#Html.Editor(prop.PropertyName) #Html.ValidationMessage(prop.PropertyName, "")</div>
}
}
There is some problem with keeping my dropdown values in ViewData or ViewBag.
When I use these, for prartyroletypeid it is not recognizing UIHint dropdownlist.cshtml. It is still referring to object.cshtml.
Instead I kept the dropdown data in TempData and everything is working fine.
But not sure, if I can use TempData in this context.
Any ideas???

Html.CheckBox not being set [asp.net mvc 4]

I am having a bit of a headache with a thing (I know something like has been asked before, but I'm pretty sure it's not quite the same thing).
To the point:
I have a View with a Telerik grid. On that grid I show some stuff from the model that I pass to the View BUT I want in the final column to put a CheckBox that is checked/unchecked based on some things in the Controller (the checks have nothing to do with the model that is being passed). In my ActionResult function that takes care of the View I store some Boolean values in the ViewData, and then I set the isChecked value in the CheckBox based on the values stored in the ViewData.
The code for the ActionResult is as follows:
[SecureThis(Roles = "User")]
public ActionResult Index()
{
//get bucket ids
var buckets = db.Buckets.ToList();
int i=1;
string cb = "checkbox" + i.ToString();
foreach (Bucket b in buckets)
{
var payByInvoice = db.PaymentOptions.Where(p => p.BucketId == b.Id).Select(p => p.CanPayByInvoice).SingleOrDefault();
if (payByInvoice == (int)PayByInvoiceState.Accepted)
ViewData["checkbox" + i.ToString()] = true;
else ViewData["checkbox" + i.ToString()] = false;
i++;
cb = "checkbox" + i.ToString();
}
return View(db.Buckets);
}
And the grid that should show all the stuff is this:
#{
int i=1;
string cb = "checkbox" + i.ToString();
}
#(Html.Telerik().Grid(Model)
.Name("BucketsGrid")
.DataKeys(keys => keys.Add(bucket => bucket.Id))
.Columns(
columns =>
{
columns.Template(model => ViewData[model.Id.ToString()])
.HeaderTemplate(
#<b>#Strings.Title_Customer</b>
);
columns.Bound(model => model.CreditFacility);
columns.Bound(model => model.Minimum);
columns.Bound(model => model.RefillLevel);
columns.Bound(model => model.NotificationEmail);
columns.Bound(model => model.NotificationSms);
columns.Template(model => Html.ActionLink(Strings.Edit, "Edit", new { id = model.Id }));
columns.Template(model => Html.ActionLink(Strings.NotificationOptions, "Bucket", "NotificationOptions", new { id = model.Id }, null));
columns.Template(model => Html.ActionLink("Refill", "Refill", "Payment", new { id = model.Id }, null));
columns.Template(model => Html.ActionLink(Strings.Details, "Details", new { id = model.Id }));
columns.Template(model => Html.ActionLink(Strings.Delete, "Delete", new { id = model.Id }));
columns.Template(model => Html.CheckBox("invoice", (Boolean)ViewData[#cb])).HeaderTemplate("Invoice Option");
#i++;
#cb = "checkbox" + i.ToString();
}
)
.Pageable(paging =>
paging.Enabled(true)
.PageSize(UserSettings.GridPageSize)
.Style(GridPagerStyles.NextPrevious)
.Position(GridPagerPosition.Bottom)
)
.Sortable()
.Scrollable()
.Resizable(resize=> resize.Columns(true))
)
The problem with this whole thing is that the checkboxes remain unchecked, no matter the data stored in the ViewData. I went with the debugger and the values are se accordingly in the ViewData, but for some reason (that I cannot yet tell) the checkboxes still remain unchcked.
Any ideas on this matter would be much appreciated.
I have found out the problem of all this. As expected, it was my own doing (or so to say). The problem was that I incremented the #i variable inside the Telerik grid declaration, thinking that it would happen for all the rows in the grid, but that thing is only triggered once. Hence, the ViewData[#cb] value would always have the 2nd value set in the Controller (which in my case was false) and all the checkboxes would then be unchecked.
The fix:
I used the ViewBag and set it up with a Dictionary<Guid, bool> to hold my values, and iterate through it using the model.Id property. For anyone who might be interested I'll post the code below.
Controller:
ViewBag.Dict = new Dictionary<Guid, bool>();
Dictionary<Guid, bool> dict = new Dictionary<Guid, bool>();
foreach (Bucket b in buckets)
{
var payByInvoice = db.PaymentOptions.Where(p => p.BucketId == b.Id).Select(p => p.CanPayByInvoice).SingleOrDefault();
if (payByInvoice != (int)PayByInvoiceState.Accepted)
{
dict.Add(b.Id, false);
}
if (payByInvoice == (int)PayByInvoiceState.Accepted)
{
dict.Add(b.Id, true);
}
}
ViewBag.Dict = dict;
View:
columns.Template(model => Html.CheckBox("invoice", (bool)ViewBag.Dict[model.Id])).HeaderTemplate("Invoice option");
