Dropdownlist reverts back to 'null' value after selection is moved in the Grid [ASP MVC 5]

I have a grid with Inline batch editing mode on. I am trying to display dropdownlist inside the grid and enable user to select values from the dropdown. The issue i am running into right now is, by default it shows null value, when clicked on that cell it shows all the dropdown values and you can select to different dropdown value. But as soon as you click outside the grid cell, it reverts the text to 'null' again. When clicked on the cell back again, it changes from 'null' to previously selected value.

ViewModel:

public class CreateAsnRequestViewModel

{

[Display(Name = "UPC UOM")]

public string UPCUOM { get; set; }

public string UserDefinedCode { get; set; }

}

public class CommonDetailsCommonProperties

{

public string ProductCode { get; set; }

public string UserDefinedCodes { get; set; }

public string UserDefinedCode { get; set; }

public string CombinedValuesToSave { get; set; }

}

public class UOMItem : CommonDetailsCommonProperties

{

public string UOM { get; set; }

}

public class CommonDetailsViewModel

{

public List<UOMItem> UOMs { get; set; }

}

Controller:

CommonDetailsViewModel commonDetailsViewModel = commonService.InvokeGetCommonDetails(flag);

ViewData["UOMList"] = commonDetailsViewModel.UOMs;

Views:

EditorTemplate: _UOMDropDownList.cshtml

@using System.Collections

@using Kendo.Mvc.UI;

@(Html.Kendo().DropDownList()

.BindTo((IEnumerable)ViewData["UOMList"])

.DataValueField("UserDefinedCode")

.DataTextField("UserDefinedCode")

.Name("UPCUOM")

)

Main Razor View:

@(Html.Kendo().Grid<SupplierPortal.ViewModels.CreateAsnRequestViewModel>()

.Name("GridViewOpenPOSelected")

.Columns(columns =>

{

columns.Bound(p => p.UPCUOM).HtmlAttributes(new { @class = "editableFiled" }).EditorTemplateName("_UPCUOMDropDownList").ClientTemplate("#:UserDefinedCode#").Width(180);

})

.Editable(editable => editable.Mode(GridEditMode.InCell).DisplayDeleteConfirmation(false))

.AutoBind(false)

.Navigatable()

.DataSource(dataSource => dataSource

.Ajax()

.Batch(true)

.PageSize(10)

.Read(read => read.Action("GetSelectedPO", "Asn").Data("GetSelectedPOParameters"))

.ServerOperation(false)

.Model(model =>

{

model.Id(p => p.Id);

}))

.Events(events => events.DataBound("gridDataBound"))

.Events(events => events.DataBinding("gridDataBinding"))

.Events(events => events.Edit("onEdit"))

)

Any help will be appreciated.

Thanks.

Transport.Create issues

I'm experimenting with the Kendo UI grid, data source, and AngularJS on the front end, and ASP.NET Web API on the back end. So far, everything is working well, except for a couple of issues creating new records. I have a Contact page, and on that page I have an Activities grid displaying various activities related to the contact.

My first issue is that I need to populate the contactID client-side when creating a new record. I am doing that using transport.create.data, but the contactID is always zero when sent to the server. I have worked around this by changing the case of the property to "ContactID" (capital C), so that it no longer matches the schema. This adds it to the list of parameters (so I have "ContactID" and "contactID") and Web API accepts it, but I must be doing this wrong. What is the correct way to handle it?

The second issue is that after a successful POST, the client-side row that was sent to the server is added to the grid. I got the impression that the JSON returned from the server after a successful POST is supposed to get added. It contains some properties (such as the activityID) that are populated server-side. How is this supposed to work?

Here's the data source code:

$scope.activityGridData = function() {

return {

type: "webapi",

transport: {

read: {

url: "api/Activities"

},

update: {

url: "api/Activities"

},

create: {

url: "api/Activities",

data: { ContactID: $scope.contact ? $scope.contact.contactid : "" }

},

destroy: {

url: "api/Activities"

}

},

serverPaging: true,

serverFiltering: true,

pageSize: 20,

filter: { field: "ContactID", operator: "eq", value: $scope.contact ? $scope.contact.contactid : 0 },

"sort": [{

"field": "isComplete",

"dir": "asc"

}, {

"field": "activityID",

"dir": "desc"

}],

"schema": {

"data": "data",

"total": "total",

"errors": "errors",

"model": {

"id": "activityID",

"fields": {

"activityID": {

"type": "number"

},

"contactID": {

"type": "number"

},

"activityType": {

"type": "number"

},

"activityTypeList": {

"editable": false,

"type": "object"

},

"activityTypeName": {

"editable": false,

"type": "string"

},

"description": {

"type": "string"

},

"notes": {

"type": "string"

},

"location": {

"type": "string"

},

"startTime": {

"type": "date",

"defaultValue": null

},

"endTime": {

"type": "date",

"defaultValue": null

},

"isAllDay": {

"type": "boolean"

},

"isComplete": {

"type": "boolean"

}

};

Initial Sort by computed field?

I've been working on getting my Kendo grid to persist across page navigation. I was able to get that to work, but when I set the initial sort to a computed field, the grid will throw an error:

Uncaught TypeError: d.GetStatus is not a function

d.GetStatus is a computed field, so the error doesn't really surprise me, but I'm not sure how to handle this so that I can set the initial sort to a field that isn't in the original dataSource (without directly modifying the DB response to include the computed value as its own property).

{

dataSource: {

schema: {

model: {

fields: {

'AmountDue': {...},

'AmountPaid': {...},

'Name': {...},

...

},

// Computed Fields

'GetStatus': function() {

return this.AmountPaid >= this.AmountDue ? 'Paid' : 'Due';

}

},

sort: {

dir: "asc",

field: "GetStatus()"

}

},

columns: [

...

{

title: 'Status',

field: 'GetStatus()'

}

]

}

Is there another way to go about creating this custom "Status" field so that the initial sorting works?

Mask without literals not functional if initialized from markup

Steps to reproduce (demo):

Define the mask in markup. Example:

<input id="someNumber" value="003123456" data-role="maskedtextbox" data-mask="0000000000" />
Initialize using kendo.init()

Expected results:

Textbox shows prompt chars on focus, only allows characters defined in mask, etc.

Actual results:

Textobx does not show prompt chars on focus (or shows "undefined" if data-clear-prompt-char is set to true), allows any characters.

Other info:

The issue does not happen if a) there is a literal in the mask, or b) the component is initialized through JS, such as $(selector).kendoMaskedTextBox(options).
