Hi,

I've created a simple MVC 5 project with a Kendo grid to display a few records from a remote server. When i run the application, the kendo grid appears but displays no records.
I checked Fiddler and found no errors or circular references. Furthermore, the JSON output shows the correct data in it but its simply not displaying in the grid. Here is the grid and controller code:

<div style="width:830px;font-size:x-small; padding-top:40px;">

@(Html.Kendo().Grid<SystemsFormsMVC.Models.vMyForm>()

.Name("Grid1")

.Columns(columns=>

{

columns.Bound(o => o.Id);

columns.Bound(o => o.SystemName);

columns.Bound(o => o.FormType);

})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(5)

.Read(read => read.Action("GetMyForms", "Home"))

)

.Pageable()

.Navigatable()

.Sortable()

.Filterable()

)

</div>

Controller:

public ActionResult GetMyForms([DataSourceRequest] DataSourceRequest request)

{

var query = _repository.GetMyForms(GetCurrentUserName());

query = query.OrderBy(s => s.RequestDate);

return Json(query, JsonRequestBehavior.AllowGet);

}

public IQueryable<vMyForm> GetMyForms(string UserName)

{

SystemsFormsDataContext db = new SystemsFormsDataContext();

IQueryable<vMyForm> query;

Int32 UserId = GetCurrentUserId(UserName);

try

{

query = (from s in db.vMyForms

where s.UserId == UserId

select s);

}

catch (Exception ex)

{

query = (from s in db.vMyForms

where s.UserId == 0

select s);

}

return query;

}

Could you please help me figure out what the issue is with the data not displaying in the grid?

Thanks, Shuja

New Export to Excel feature in version 2014.3.1119

I am reviewing the new export to Excel feature in version 2014.3.1119. This feature is really nice, but I cannot find a way to correctly export a grid with dropdownlists. The export shows the column, but include the foreign key, not the dropdownlist text. The new Export to PDF works correctly and downloads the text for the dropdownlist. Is there a way to get the Export to Excel to work correctly on dropdownlists?

Thanks for your help.

TreeView get childs with a POST

I have a treeview with remote data binding. Every time I expand a node it does a GET with the parent Id as parameter. Is it possible change the GET for a POST?

The reason to do this is for security. We either need to encrypt the parameter on the GET or change it as a POST.

Telerik.UI.for.AspNet.Mvc5

Hi,

We've just come to integrating our product which uses the Telerik.UI.for.AspNet.Mvc5 NuGet package and we get errors stating that it cannot be found. Having looked at Nuget.org, it seems that it has disappeared.

Any reason for this, or is there an alternative location that I can use? I notice a ZIP file in my Product download page. I guess I need to host that locally. THough I would like confirmation that the original NuGet repository package has disappeared - and why considering this will break a lot of builds.

Thanks

Monthly/Yearly aggregate

I would like to create sub total rows and group header rows for Monthly and Yearly totals and counts. I have a date field and a payment field. I can't see any way of doing this without creating extra columns in my data. Is there an example that works with dates that is available anywhere?

Thanks,

Larry

TreeList LoadOnDemand

I am trying to use the TreeList widget (http://demos.telerik.com/kendo-ui/treelist/index), but with a lot of data (~2000 rows). It seems to not handle this well as it tries to load all everything at once.

There is a similar TreeView widget (http://demos.telerik.com/kendo-ui/treeview/index), which allows for a configurable method called “LoadOnDemand” (http://docs.telerik.com/kendo-ui/api/javascript/ui/treeview#configuration-loadOnDemand) that allows the children for a node to be loaded when the parent is expanded, but I can't seem to find a similar function for the treelist widget.

Is there an alternative way to achieve the same functionality (loading the children on expand of their parent)?

[Solved] Override default key event methods

Hi,

We're using numeric textboxes in a grid that allows for keyboard navigation. The problem is that the up/down arrows still increase and decrease the values in the textbox before the navigation event occurs. Is there a way to disable the default key events, or modify them?

Thanks,
Kevin

Multiselect dropdown list not showing when initial value set from Model

I have a multiselect in a form on a pop up window and I finally got the initial value(s) from the model showing when the window opens, but now when there is an initial value, the select list does not work. I click in the field - no list. It shows the list when I click in the field and there is no initial value and my placeholder text is showing. I need help please! I've added code below and attached screen shots.

Here is my code for the multiselect list:

<div class="form-group">

@Html.Label("User Role(s)")

@{

(Html.Kendo().MultiSelectFor(model => model.SelectedRoles)

.Name("SelectedRoles")

.HtmlAttributes(new {style = "width: 400px"})

.Placeholder("Please select role(s)...")

.DataTextField("Name")

.DataValueField("Id")

.DataSource(source =>

{

source.Read(read =>

{

read.Url("/api/gmcmembership/roles").Type(HttpVerbs.Get);

});

})

.Value(Model.SelectedRoles)

.AutoBind(false)

).Render();

}

</div>

Here is the code for the Models:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

namespace GMCWebApplication.Areas.admin.Models

{

public class UserDetailViewModel

{

[HiddenInput]

public string Id { get; set; }

public int CompanyCode { get; set; }

public string UserType { get; set; }

public int Question1 { get; set; }

public int Question2 { get; set; }

public string Question1Answer { get; set; }

public string Question2Answer { get; set; }

// public string PasswordHash { get; set; }

public string PhoneNumber { get; set; }

public string NewPassword { get; set; }

public List<UserRoleViewModel> SelectedRoles { get; set; }

public List<UserRoleViewModel> AllRoles { get; set; }

}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace GMCWebApplication.Areas.admin.Models

{

public class UserRoleViewModel

{

public string Id { get; set; }

public string Name { get; set; }

}

Here's the api code to get the list of all roles:

[System.Web.Http.HttpGet]

[System.Web.Http.Route("roles")]

public IHttpActionResult GetRoles()

{

try

{

var list = new List<UserRoleViewModel>();

using (var context = new ApplicationDbContext())

{

list = context.Roles.Select(p => new UserRoleViewModel { Id = p.Id, Name = p.Name })

.ToList<UserRoleViewModel>();

}

return Ok(list);

}

catch (Exception ex)

{

Elmah.ErrorSignal.FromCurrentContext().Raise(ex);

return InternalServerError();

}

Any help is very much appreciated!

Series tootip

I'm trying unsuccessfully to set different tool-tips for different series.

I want some series tool-tips to be visible but others not. It seems that the visibility of the tool-tip on the last series determines the visibility of the tool-tips on ALL series. Does it have to be this way or am I doing something wrong.

.Series(series => { series.Donut(Model.Data.Bands.Where(b => b.ID == 1).First().Sections); }).Tooltip(t => t.Visible(true))
.Series(series => { series.Donut(Model.Data.Bands.Where(b => b.ID == 2).First().Sections); }).Tooltip(t => t.Visible(false))

The above hides the tool-tips on both series.
