Questions on Kendo UI for jQuery Forum

Hi,

I am using MVC4 with Entity Framework 5 and I have the following piece of code that I got using samples posted on your website. Apparently, the Grid does not load at all. Am I missing something here?

I do want to mention that the Admin controller is in an "Admin" Area and I have routed requests to the Admin section correctly. Also the UnitOfWork object returns an IEnumerable object which I transpose to Kendo's DataSourceRequest. Currently, this function returns two objects in my test cases and I can see that when I go directly to the url that is bound to the read portion of the dataSource object.

Below is the Controller code.

Imports PropertyCentral.Domain.Entities

Imports PropertyCentral.Domain.Interfaces

Imports PropertyCentral.Domain.Repositories

Imports Kendo.Mvc.UI

Imports Kendo.Mvc.Extensions

Namespace Admin.Controllers

'<Authorize(Roles:="Administrator")>

Public Class UsersController

Inherits System.Web.Mvc.Controller

Private _uow As IUnitOfWork

Public Sub New(uow As IUnitOfWork)

If uow Is Nothing Then

Throw New ArgumentNullException("uow")

End If

_uow = uow

End Sub

'

' GET: /Admin/Users

Function Index() As ActionResult

Dim users = _uow.Users.SelectAll().AsEnumerable()

Return View("~/Areas/Admin/Views/Users/Index.vbhtml", users)

End Function

'

' GET: /Admin/Users/Users_Read

Function Users_Read(<DataSourceRequest()> request As DataSourceRequest) As ActionResult

Dim users = _uow.Users.SelectAll().AsEnumerable()

Return Json(users.ToDataSourceResult(request), JsonRequestBehavior.AllowGet)

End Function

End

Class

End Namespace

Here is the View:

@ModelType System.Collections.Generic.IEnumerable(Of PropertyCentral.Domain.Entities.User)

@Code

ViewData("Title") = "Administration/Users"

Layout = "~/Views/Shared/_Layout.vbhtml"

End Code

<div class="widget-box">

<div class="widget-title">

<span class="icon">

<i class="icon-th"></i>

</span>

<h5>Users</h5>

</div>

<div class="widget-content nopadding">

@*<div id="userGrid" style="height:380px;"></div> *@

@Code

Html.Kendo.Grid(Of PropertyCentral.Domain.Entities.User)(Model) _

.Name("UserGrid") _

.Columns(Sub(column)

column.Bound(Function(u) u.UserID)

column.Bound(Function(u) u.UserName)

column.Bound(Function(u) u.FirstName)

column.Bound(Function(u) u.LastName)

column.Bound(Function(u) u.EmailAddress)

column.Bound(Function(u) u.PhoneNumber)

End Sub) _

.DataSource(Sub(dataSource)

dataSource _

.Ajax() _

.Read(Sub(read)

read.Action("Users_Read", "Users", New With {.Area = "Admin"})

End Sub)

End Code

</div>

Could you please tell me why the Grid won't load the data?

Thanks,
Akshay

Editing an element on a sorted/filtered kendodatasource

Hi all, it seems that there is a weird bug when trying to edit an element on a sorted/filtered data source, both the element that will be in the previous position of the edited element and the edited element by itself in the new position gets updated with the new values.

I found that clearing the filter first and then resorting/refiltering will solve it.

datasource.filter([]);

var c = datasource.get(id);

c.set("Property", "New Value");

datasource.filter([{

field: "Property",

operator: "==",

value: "New Value"

}]);

ForeignKey column does not produce dropdown list in popup editing

I have a grid, with a detail grid and some of the fields in the detail grid refer to foreign key columns.When the editimode is set to inline this produces a dropdown list from which the user can pick a value. But if I change the editmode to popup the field is displayed as a textbox with the numeric key value instead of as a drop down list. Is this by design?

Is it possible for me to extend the Html Helper?

Need help with dataSource.Read

Hi, I try to change data from a combobox dynamically.
I got a object containing a javascrip array (Module.Collection)
I create the combobox like:

$("#cboListe").kendoComboBox({

dataTextField: "Nom",

dataValueField: "Id",

dataSource: Module.Collection,

filter: "contains",

suggest: true,

index: 1,

});

Then when the user click on a button, I call this function:

this.AddItemColl = function () {

Item = new ObjetA();

Item.Id = this.Collection.length + 1;

Item.Nom = "Nom" + (this.Collection.length + 1);

this.Collection.push(Item);

var combobox = $("#cboListe").data("kendoComboBox");

combobox.dataSource.read();

}

The collection object grow, but the combobox do not reflec change wih the dataSource.Read();
Any idea?
Thanks a lot.

Grid change event firing issue

I notice the following 'features' after attaching a change event to a grid.
1) The change event fires even when an already selected row is clicked on.
2) The change event fires when clicking on an anchor or a button element in a grid's row.

Any work-around suggestion for the grid to not fire the change event in the above cases is appreciated.

Thank you in advance.

ThemeBuilder widgets not functional

Hi Guys!

It's great to see the addition of the three new widgets to the ThemeBuilder page but i noticed when trying to use the AutoComplete and MultiSelect by typing to bring up the results list it doesn't happen because there is a javascript error being thrown. I'm trying to get a look-and-feel using real life functionality of Kendo UI suite of widgets under different themes.

Could we have this full functionality of AutoComplete and MultiSelect widgets enabled in ThemeBuilder page ?

Cheers!
