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

Nathan

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

Arithmetic calculations in kendo format

Hi Team,

I am displaying a pie chart in ASP.Net MVC.

.Series(series =>
{
series.Pie(new dynamic[] {
new {category="Forms Created",value=Model.value1,color="#9de219"},
new {category="Forms Allowed",value=Model.value2,color="#50dd48"}

})
.Tooltip(tooltip => tooltip
.Visible(true)
.Template("#= category # - #= kendo.format('{0}', value)#")
)

Now the tool tip is displaying the value of corresponding category.

I would like to display value of (category 1 value - category 2 value) in my tool tip.

Could you advise is this is possible to format in kendo?

Thanks.

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.

[Solved] Updated to 2014.3.1119: Several JS errors in Grid

Hi there. Yesterday, I have updated my MVC project to Telerik UI for ASP.NET MVC 2014.3.1119. I was updating from version 2014.2.1008. However, several javascript errors appear, and some basic functionality is not working.

I will provide two examples of malfunctioning I ran into.

1. Pagesizes:

@(Html.Kendo().Grid(Model)

.Name("ServiceGrid")

.Pageable(action => action.Enabled(true)

.ButtonCount(8)

/*.PageSizes(new[] {25, 100, 500}) TODO this yields an error in the current Telerik */

.Refresh(true))

.DataSource(data => data

.Ajax()

.Events(events => events.Error("grid_onError"))

.Model(model =>

{

model.Id(m => m.Name);

})

.Read(read => read.Action("Get", "Service"))

.Group(g => g.Add(f => f.Host))

)

.Columns(column =>

{

column.Bound(ci => ci.FriendlyName).Title("Service");

column.Bound(ci => ci.Host).Hidden();

column.Bound(ci => ci.Status);

column.Command(cmd => cmd.Custom("Restart Service").Click("onClickRestartService")).Width(120).Title("Actions");

}))

The commented out line shows what was functioning correctly in version 2014.2.1008, but isn't anymore in 2014.3.1119. This JS error appears when I uncomment the code:

Uncaught TypeError: undefined is not a function

kendo.web.min.js:11 ht.extend.pageSize

jquery-2.1.1.js:7328 (anonymous function)

jquery-2.1.1.js:375 jQuery.extend.each

jquery-2.1.1.js:139 jQuery.fn.jQuery.each

jquery-2.1.1.js:7320 jQuery.fn.extend.val

kendo.web.min.js:20 u.extend.init

kendo.web.min.js:29 ut.ui.DataBoundWidget.extend._pageable

kendo.web.min.js:28 ut.ui.DataBoundWidget.extend.initkendo.web.min.js:10 (anonymous function)

When I click on the error, Chrome leads me to this place in the kendo.web.min.js code:

pageSize:function(e){var n=this;return e!==t?(n._query({pageSize:e,page:1}),t):n.take()},sort

(with the cursor positioned at 'n._query')

2. Export to Excel
I wanted to add the new 'Export to Excel' functionality to most of my grids. I have added the required method to my Controller, and have added the two relevant code snippets to the Razor grid code (the toolbar part and the the Excel-part with the ProxyURL, fileName and filterable).

The button appears correctly, however, when I click it, this JS error appears in the console:

Uncaught TypeError: undefined is not a function

kendo.dataviz.min.js:12 ht.extend.success

kendo.dataviz.min.js:12 n.trigger.n.online.n.transport.read.success

kendo.dataviz.min.js:11 n.success

jquery-2.1.1.js:3073 fire

jquery-2.1.1.js:3185 self.fireWith

jquery-2.1.1.js:8251 done

jquery-2.1.1.js:8598 (anonymous function)

When I click the error, the console leads me to this JS part in kendo.dataviz.min.js:

a._pristineData=e.slice(0),a._detachObservableParents()

(more specifically, at 'slice').

My gut feeling tells both these errors have the same cause.
I have made sure the version is updated completely by using kendo.version(), and by checking the served file headers in the Chrome developer tools.
I would be very glad if someone could point me in the right direction..
