Kendo MVC TreeView not rendering ".k-in" items correctly - kendo-ui

We're using Kendo UI MVC 2019.2.619 in our MVC5 project.
Our TreeView is rendering like this:
We took a look at the HTML it's generating at our end
But it should look like this
(Source: https://www.telerik.com/forums/k--items)
This is how we generate our TreeView.
#(Html.Kendo().TreeView()
.Name("BroadcastTreeView")
.DataTextField("Text")
.DataSource(dataSource => dataSource
.Model(model => model
.Id("Id")
.HasChildren("HasChildren")
.Children("Items"))
.Read(read => read.Type(HttpVerbs.Post).Action("ReadTree", "Broadcast").Data("treeViewReadData"))
.Events(events => events.RequestEnd("onRequestEnd")))
.Messages(msg => msg
.Loading("Data ophalen...")
.RequestFailed("Kan data niet ophalen")
.Retry("Probeer opnieuw"))
.Events(events => events
.Change("onTreeViewChange")
.Expand("onTreeViewExpand"))
.HtmlAttributes(new { #class = "custom-border" }))
When we drag the .k-in span outside of the .k-icon span in the Chrome debugger. The layout is like it's supposed to be. We do not have any custom JavaScript that's manipulating the TreeView. Is this a known bug with version we're using? Thank you.

Have you upgraded your jQuery to 3.5 recently? It doesn't allow for some self-closing tags, like <span class="k-icon" /> which are present in Kendo's source.
See https://github.com/telerik/kendo-ui-core/issues/5735 .
You need to upgrade Kendo or downgrade jQuery .

We've searched for a couple of hours, but no luck. We made the decision to upgrade to Kendo 2020.5.513. It makes for some layout issues but it has fixed the issue with the treeview.

Kendo Grid Multiple Hyperlinks in single column

I am using following code to display data from server in a Kendo Grid.
Working fine.
I want to put two hyperlinks in last cell of each row, but can do with only one.
I want EDIT and DELETE link in same cell.
How can I achieve this?
CODE
#(Html.Kendo().Grid(Model)
.Name("Grid")
.Columns(columns =>
{
columns.Bound(u => u.USERNAME);
columns.Bound(u => u.PASSWORD);
columns.Bound(u => u.ROLE);
columns.Bound(u => u.STATUS);
columns.Template(c => Html.ActionLink("Edit", "Edit", new { id = c.ID }));
}
)
.Pageable()
)
There are a couple of ways to do this.
First you could use the inbuilt edit/delete options from within the grid config
like so:
columns.Command(command =>
{
command.Edit();
command.Destroy();
});
Then just wire up the edit config and destroy delete commands appropriately.
Alternatively you can template these out using one of two methods:
First inline template:
columns.Bound(c => c.ID).ClientTemplate("<a href='Edit/#=data.ID#'>Edit Link #=data.ID#</a>
<a href='Delete/#=data.ID#'>Delete Link #=data.ID#</a>")
So this is just bound to a column and the template is added as per your requirements using standard html and javascript if required. This is fine for simple things but can get very clunky fast if you have more complex templates which then leads to the second method creating a template and calling that like this:
columns.Bound(c => c.ID).ClientTemplate("#=getButtonTemplate(data,'buttonsTemplate')#")
then create your template like so:
<script id="buttonsTemplate" type="text/x-kendo-template">
<div class='btn-group'>
<a class="btn btn-primary" href='#Url.Action("{edit action}", "controller")/#=ID#'>Edit Link #=ID#</a>
<a class="btn btn-danger" href='#Url.Action("{delete action}", "controller")/#=ID#'>Delete Link #=ID#</a>
<div>
</script>
then the getButtonTemplate function:
function getButtonTemplate(data, templateName) {
var templateObj = $("#" + templateName).html();
var template = kendo.template(templateObj);
return template(data);
}
So let me explain what is going on here with this second method.
Instead of templating the html in the column we extract it out into two components for want of a better word.
We use the getButtonTemplate function to pass 2 params in the data item and the template's id. This function simply loads the passed data object into the template and the kendo magic renders the html and injects the values in as required. Check the kendo demo site for more info on this subject.
The template element can be a mix of html and javascript so if you needed to apply some logic in the template this can be done in here. Again refer to the kendo site for more info on this subject.
I personally prefer the second method of doing this client templating as it is easier to manage and make changes without rogue hash's or brackets breaking code.
If you need any more info let me know and I will update the answer for you.

Yii2. Language picker widget not working properly

I use \lajax\languagepicker in Yii2.
Languagepicker dropdown located in header nav inside <li> element.
$menuItems [] = '<li>'.LanguagePicker::widget(['skin' => LanguagePicker::SKIN_DROPDOWN, 'size' => LanguagePicker::SIZE_LARGE,
'itemTemplate' => '<li><i class="{language}"></i></li>',
'activeItemTemplate' => '<i class="{language}"></i>',
]).'</li>';
Language of website is changing only when I add below code to the view being rendered:
use \lajax\languagepicker\widgets\LanguagePicker;
LanguagePicker::widget();
If above code is not added Language does not change.
I suspect it can be related to ajax loading.
What could be a problem?
Check your DB in user table column language
Add it if not exist.
After that LanguagePicker start working for me.

Kendo UI Grid is not calling READ method

As per the requirement, I am having a Kendo UI grid on my VIEW.But sadlyy, the read function is not being hit in the controller.This is annoying ,I am getting the same problem even though everyhting seems to be as per the documentation provided on http://demos.kendoui.com/web/grid/index.html. Here is my View code:
#(Html.Kendo().Grid<StudentManagement_Models.Student>()
.Name("studentsGrid")
.Columns(columns =>
{
columns.Bound(p => p.Id).Groupable(false);
columns.Bound(p => p.FirstName);
columns.Bound(p => p.MiddleName);
columns.Bound(p => p.LastName);
columns.Bound(p => p.CGPA);
})
.AutoBind(true)
.Pageable()
.Navigatable()
.Sortable()
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("GetAllStudents", "Student"))
)
)
Here is my controller action:
public ActionResult GetAllStudents([DataSourceRequest] DataSourceRequest request)
{
//Thread.Sleep(2000);
StudentManagement_Models.Student student = new StudentManagement_Models.Student();
StudentHelper helper = new StudentHelper();
student.SavedStudents = helper.GetAllStudents();
return Json(student.SavedStudents.ToDataSourceResult(request));
}
How would I tackle this ?Am I missing something ?Kindly suggest.
Thanks in advance.
Add all of this file in your page
<script src="~/Script/Jquery-1.8.1.min.js" type="text/javascript"></script>
<script src="~/Script/jquery-ui-1.8.20.min.js" type="text/javascript"></script>
<script src="#Url.Content("~/Script/kendo.all.min.js")" type="text/javascript"></script>
<script src="~/Script/kendo.web.min.js" type="text/javascript"></script>
<script src="~/Script/kendo.aspnetmvc.min.js" type="text/javascript"></script>
<link href="~/Content/kendo.common.min.css" rel="stylesheet" type="text/css" />
<link href="~/Content/kendo.default.min.css" rel="stylesheet" type="text/css" />
I think you mis one of the js in your page , probebly Jquery-1.8.1.min.js .
I was having similar issue with the MVC version.
I noticed I was getting a 404 but when clicking the 404'd link in the Chrome debugger it would indeed hit my controller method. Then I noticed that it was using POST (and I had HttpVerbs.Get) specified.
Then I found this (from http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/troubleshooting):
By default Kendo Grid for ASP.NET MVC should make POST requests when
configured for ajax binding. This is implemented by a custom
DataSource transport and schema. Those are defined in the
kendo.aspnetmvc.min.js. Make sure that this file is included after the
other Kendo JavaScript files.
After verifying that the scripts were indeed in the correct order (and knowing it probably had something to with POST) I specified the verb to use at the end of my Read in the grid as so:
.Read(read => read.Action("MyList_Read", "Diagnosis").Type(HttpVerbs.Get))
This solved MY problem.
try to call the read method with JQuery's document.ready()
$(document).ready(function ()
{
var grid = $("#studentsGrid").data("kendoGrid")
grid.dataSource.read()
})
Also is savedStudent a type of student.... Ur grid is bound to Student but you are returning SavedStudent objects
"By default Kendo Grid for ASP.NET MVC should make POST requests when configured for ajax binding. " ???
For Kendo UI version 2014.1.318, I think, by default Kendo Grid for asp.net mvc makes GET requests when configured for ajax binding.
I discovered that if there are two grids on the same webpage (in this case, in different tabs), then each grid MUST have its own datasource method in the MVC controller - even if both grids are using the same data,

Using KendoUI DetailTemplate- How do I use literal for AJAX results

Using the DetailTemplate grid example for KendoUI as my basepoint
http://demos.kendoui.com/web/grid/detailtemplate.html
I am trying to add a HREF link to the Orders tab that would open up another page.
I have tried using the #= OrderId # notation, but this seems to only access the first AJAX call result set - that is the data returned pulling back the users information.
I want to be able to access the information pulled back for the orders - see code snippet below
I have tried using the ClientTemplate method but to no avail, as it can't access (or it doesn't exist) the #= OrderId # literal.
I am using AJAX to pull the info for both sets of data, so don't seem able to use the Template method.
Any advice on accessing this level of JSON data returned as a secondary call would be greatly appreciated.
<script id="employeesTemplate" type="text/kendo-tmpl">
#(Html.Kendo().TabStrip()
.Name("TabStrip_#=EmployeeID#")
.SelectedIndex(0)
.Items(items =>
{
items.Add().Text("Orders").Content(#<text>
#(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.OrderViewModel>()
.Name("Orders_#=EmployeeID#")
.Columns(columns =>
{
columns.Bound(o => o.OrderID).Width(101);
columns.Bound(o => o.ShipCountry).Width(140);
columns.Bound(o => o.ShipAddress).Width(200);
columns.Bound(o => o.ShipName).Width(200);
Thanks in advance

.ClientTemplate("\\#:OrderId \\#");
Notice double back slashes.

Telerik Asp mvc NumericText Validation jQuery Culture Pb

I am using Telerik for asp mvc and I used the Html.Telerik().NumericTextBoxFor
#(Html.Telerik().ScriptRegistrar().Globalization(true).DefaultGroup(group => group.Combined(true).Compress(true)))
#(Html.Telerik().NumericTextBoxFor(loc => loc.LatitudeValue).MinValue(0).MaxValue(90).Spinners(false).InputHtmlAttributes(new { width = "120", style = "width: 120px" }))
When the navigator is in English it works, but when I switch to French the separator became "," which is great, but when I write for example 12,45 . jQuery removes the ,45 and puts ,00
Did I miss something?
Your ScriptRegistrar should be after the numeric textbox. The globalization online example works as expected for me.
