Empty Grid

I am trying something simple, or what should be simple. Creating a Kendo MVC Grid, and populating it via Ajax. Before you suggest it, I have looked in the developer tools in Chrome, and there are no Javascript errors whatsoever. No exceptions in the code, and no javascript errors. It will most likely be something simple, but I just cannot seem to find it.

I have placed a breakpoint in the action in which it should be calling, and it never, ever even calls it. If it at least called it, I'd know where to start looking, but it never calls it. And again, no javascript errors whatsoever, as shown in the attached screen capture.

My cshtml page:

@{

ViewBag.Title = "Index";

}

<h2>Index</h2>

@(Html.Kendo().Grid<User>()

.AutoBind(true)

.Name("userGrid")

.Columns(cols => {

cols.Bound(c => c.UserId);

cols.Bound(c => c.FirstName);

cols.Bound(c => c.LastName);

cols.Bound(c => c.UserName);

})

.Scrollable()

.Sortable()

.Pageable(pageable => pageable

.Refresh(true)

.PageSizes(true)

.ButtonCount(5))

.DataSource(ds => ds

.Ajax()

.Read(r => r.Action("AllUsers", "Home").Type(HttpVerbs.Get))

.PageSize(20))

)

My Controller is also just as simple:

using System.Collections.Generic;

using System.Web.Mvc;

using Kendo.Mvc.Extensions;

using Kendo.Mvc.UI;

using TelerikMVC_Template.Models;

using TelerikMVC_Template.Repository;

namespace TelerikMVC_Template.Controllers

{

[Authorize]

public class HomeController : Controller

{

private readonly IUserRepository userRepository = new UserRepository(new VUsersContext());

// GET: Home

public ActionResult Index()

{

return View();

}

[HttpGet]

[ActionName("AllUsers")]

public JsonResult AllUsers([DataSourceRequest]DataSourceRequest request)

{

IEnumerable<User> theseUsers = userRepository.SelectAll();

return Json(theseUsers.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

And finally my User class definition:

public class User

{

public System.Guid UserId { get; set; }

public string UserName { get; set; }

public string Email { get; set; }

public string FirstName { get; set; }

public string LastName { get; set; }

public string Comment { get; set; }

public string Password { get; set; }

public System.DateTime LastLoginDate { get; set; }

public System.DateTime LastPasswordChangedDate { get; set; }

public System.DateTime CreationDate { get; set; }

public bool IsLockedOut { get; set; }

public bool IsActive { get; set; }

public int FailedPasswordAttemptCount { get; set; }

public System.DateTime? LastPasswordFailedDate { get; set; }

public System.DateTime CreatedDate { get; set; }

}

2 grids based on 1st grid selected checkboxes ask stored procedure to populate 2nd grid

I understand how to pass additional data as a parameter example I am doing this
.Read(read => read.Action("GetOpenInvoices", "Maint", new { cust = Request.QueryString["cust"] }))
Is it possible to have Parent/child or grid/details grid to do without entity framework meaning asking custom stored procedures for the data?
I have a grid with Invoices. I want user to select multiple checkboxes and then click the button and based on that 2nd grid gets populated.
or have a parent grid loaded and based on checkboxes (invoice# which is a string) I click ask stored procedure to get me corresponding comments.
Initially 2nd grid is empty.
If you have any example that will be great.
I want an example without entity framework.
Please reply if there is any easy solution.

Thank you,
Gaurav

How to fail the mvc controller on purpose and do nothing

Controller Method:

public ActionResult GetCustomerComments([DataSourceRequest] DataSourceRequest request, string invoices)
{
if (invoices != "fail")
{

List<JNI.Enterprise.Contracts.CustomerComments> customer = InvoiceService.GetCustomerComments(invoices);

return Json(customer.ToDataSourceResult(request));
}
else
{
//do nothing
}
}

I am trying to upgrade the grid using ajax
$.ajax({
url: webManager.resolveUrl("~/maint/GetCustomerComments"),
method: "POST",
data: { invoices: invoicesList },
success: function () {
var grid = $('#CustomerCommentsGrid').data('kendoGrid');
grid.dataSource.read();
grid.refresh();
},
error: function () {
alert('an error occurred');
}

});

But the problem is Grid is called again and I want to stop that.

@(Html.Kendo().Grid<CustomerComments>()
.Name("CustomerCommentsGrid")
.Columns(columns =>
{
columns.Bound(i => i.INVOICE).Title("Invoice").Width(15);
columns.Bound(i => i.Comment).Title("Comment").Width(40);

}).Pageable(pageable => pageable
.Refresh(true)
)
.Scrollable()
.Sortable()
.Filterable()
.DataSource(dataSource => dataSource
.Ajax().UseJniErrorHandler()
.PageSize(10)
.Read(read => read.Action("GetCustomerComments", "Maint", new { invoices = "fail" }))
)
)

kendo.toString Syntax for shared popup editor

I have a custom popup editor that's used as the editor in a parent grid and in the nested grid of another parent grid:

Grid 1 -> Shared Custom Popup
Grid 2 >Tabstrip > Nested Grid -> Shared Custom Popup

In the popup editor, I have a field "created_date" that I need to display as a string instead of an editor box. I know that for popup editors of a parent grid, I need to use this syntax:

${kendo.toString(created_date, "MM/dd/yyyy hh:mm tt")}

And for popup editors of a nested grid, I need to use this syntax:

#= kendo.toString((created_date), "MM/dd/yyyy hh:mm tt") #

The syntax for popup editors of a parent grid won't work for the popup editors of a nested grid and vice versa.

How would I display a string for a field in a popup editor that's shared between a parent grid and the nested grid of another parent grid?

Grid showing no records after sort

I have a simple Kendo UI grid setup for serverside processing which displays some employee information. The grid displays just fine when i first load the view but as soon as you click on a column to sort it refreshes and just gives me an empty grid. The Action is firing each time a column header is click and is returning the correct amount of records to the view. See my code below:

View:

@ModelType List(Of ConnectEntities.Employee)

@Code

ViewData("Title") = "CompanyDirectory"

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

End Code

<div class="row">

<div class="col-md-12">

<div class="panel panel-primary">

<div class="panel-heading">

<h4>Company Directory</h4>

</div>

<div class="panel-body">

@Code

Html.Kendo.Grid(Of ConnectEntities.Employee)() _

.Name("employeeDirectory") _

.BindTo(DirectCast(ViewData("employees"), IEnumerable(Of ConnectEntities.Employee))) _

.Columns(Sub(c)

c.Bound(Function(p) p.FirstName_AD).Sortable(True)

c.Bound(Function(p) p.LastName_AD)

c.Bound(Function(p) p.JobTitle_AD)

c.Bound(Function(p) p.PhoneNumber_AD)

End Sub) _

.DataSource(Sub(d)

d.Server() _

.Read(Function(read) read.Action("Person_Read", "Home"))

End Sub) _

.Sortable() _

.Filterable() _

.Render()

End Code

</div>

Controller Code:


Function CompanyDirectory() As ActionResult
 
    Dim employees As List(Of ConnectEntities.Employee)
 
    Using connectDB As New ConnectEntities.ConnectEntities
        employees = connectDB.Employees.ToList
    End Using
 
    ViewData("employees") = employees
 
    Return View()
 
 
End Function


Public Function Person_Read() As ActionResult
 
 
    Dim employees As List(Of ConnectEntities.Employee)
 
    Using connectDB As New ConnectEntities.ConnectEntities
        employees = connectDB.Employees.ToList
    End Using
 
    Return View("CompanyDirectory", employees)
 
 
End Function

Splitting hairs. Or words.

Hi,

The grid column headers split the view model property names when there is an uppercase character in the viemodel property name. That is good. But when I have an non-English character in the name the column header will also be split. Is this the intended behaviour? I know I can workaround the issue by using DisplayName in the model or .Title() in the grid, but that is a lot of unnecessary work.

ViewModel:

    public class AvslagnaIndexViewModel
    {
        public Guid Id { get; set; }
        public string DiarieNummerSSM { get; set; }
        public DateTime AnsökningsDatum { get; set; }
        public string Handläggare { get; set; }
        public string ExportörNamn { get; set; }
        public string SlutanvändareNamn { get; set; }
        public string BestämmelseLandNamn { get; set; }
        public string Status { get; set; }
    }

Grid columns:
        .Columns(columns =>
        {
            columns.Bound(p => p.Id).Hidden().Title("Id");
            columns.Bound(p => p.DiarieNummerSSM).ClientTemplate(
                Html.ActionLink("#=DiarieNummerSSM#", "Details", "Avslagna", new { id = "#=Id#" }, new { title = "Visa ärendedetaljer", @class = "k-link k-grid-edit-row" }).ToHtmlString()).Width(120);
            columns.Bound(p => p.AnsökningsDatum).Format("{0:yyyy-MM-dd}");
            columns.Bound(p => p.Handläggare);
            columns.Bound(p => p.ExportörNamn);
            columns.Bound(p => p.SlutanvändareNamn);
            columns.Bound(p => p.BestämmelseLandNamn);
            columns.Bound(p => p.Status);
        })

See the attached image for the result. All words containing non-English caracters are split in more places than they should be. As you can see "BestämmelseLandNamn" is shown as "Bestä mmelse Land Namn"

Best regards,

Henrik

kendo mvc window Object doesn't support property or method 'open'

I am trying to open a kendo window based on input from a form. I am getting this error:

JavaScript runtime error: Object doesn't support property or method 'open'

The error occurs when win.open(); is called in the JavaScript in the view as listed below. Any help would be great.

Here is my controller:

using Kendo.Mvc.UI;

using Kendo.Mvc.Extensions;

using KendoGridAjaxBinding.Models;

using System;

}

return View("Index", m);

}
