I have decided to switch to tag helper as I have just realized how natural it looks and format in a sizeable cshtml file. I converted all essential elements to tag-helper equivalents. I need the following converted that I'll use for the remaining advanced controls:
A complex grid:
@(Html.Kendo().Grid(Model)
.Name("gridLetters")
.Columns(columns =>
{
columns.Bound(p => p.Identifier).Title("RL #").Filterable(false).Sortable(false).Width(160)
.HeaderHtmlAttributes(new { style = "k-text-center !k-justify-content-center" })
.HtmlAttributes(new { style = "k-text-center !k-justify-content-center" })
.ClientTemplate("<a href='" + Url.Action("View", "Letter", new { letterId = "#:Id#" }) + "'>#=Id#</i></a>");
columns.Bound(p => p.Subject);
columns.Bound(p => p.CompanyName).Title("Company");
columns.Bound(p => p.BrandName).Title("Brand");
columns.Bound(p => p.Location.Name).Title("Location");
columns.Bound(p => p.LetterTypeId).Title("RL Type").Width(150)
.HtmlAttributes(new { style = "text-align:center" })
.HeaderHtmlAttributes(new { style = "text-align: center; justify-content: center" })
.ClientTemplate("<span class='#=LetterType.BadgeInfo#' title='#=LetterType.Name#'>#=LetterType.Nickname#</span>");
columns.Bound(p => p.Status.Nickname).Title("Status").Width(150)
.HtmlAttributes(new { style = "text-align:center" })
.HeaderHtmlAttributes(new { style = "text-align: center; justify-content: center" })
.ClientTemplate("<span class='#=Status.BadgeInfo#' title='#=Status.Name#'>#=Status.Nickname#</span>");
columns.Bound(p => p.Id).Title("Act").Width(90).Filterable(false)
.HtmlAttributes(new { style = "text-align:center" })
.HeaderHtmlAttributes(new { style = "text-align: center; justify-content: center" })
.ClientTemplate(
"#if(StatusId == 1){#" +
" <a href='" + Url.Action("Create", "Letter", new { letterId = "#=Id#" }) + " ' title='Edit the RL'><i class='fa-duotone fa-pen-to-square'></i></a>" +

We cannot upgrade the package Telerik.UI.for.AspNet.Core to the versions after 2022.1.412. The project cannot start after the upgrade.
We use .Net Core 2.1 over .Net Framework 4.8 and it's easy to reproduce, juste create a new project (core 2.1 over .net framwork) and add the nuget Telerik.UI.for.AspNet.Core 2022.2.xxx.
Thanks

I have a general idea of the flow:
(i) Assign a unique id to your form (eg form-id) by changing your form code to:
@using (Html.BeginForm("SaveCountry", "Country", FormMethod.Post, new { id = "form-id" })) {
}(ii) Put the loader on your page with a unique id. The div is hidden until the form is submitted. Need to use Kendo Loader here and place it in either a partial view or in _Layout so it is always available as hidden--by-default
(iii) Style the loader / loading div to go somewhere useful.
(iv) Show the loader when the form is submitted (and after any validation has been completed), for example (not sure about this):
<script>
$("#form-id").on("submit", function () {
$("#divLoading").show();
});
</script>(v) Given that the page will redirect, I can probably leave the loader until the page redirects. But if I need to hide the loader before that happens, I can use (Kendo Loader here + function defined in _layout as well):
$("#divLoading").hide();

I wanted to rule out if this is some kind of issue with Telerik - I've implemented this in CodePen and it works there, but not with what I'm using in Visual Studio w/ the entire code.
I have a series of buttons like so:
<wizard-step title="Step 2">
<wizard-step-content><span class="nowrap d-flex flex-row"><div class="reasons">
@Html.RadioButtonFor(c => c.category, item.Value, new { id = item.Value, name = "Lists", @value = item.Value, @text = item.Text, @class = "reasons-input"})
<label for="@(item.Value)"
class="reasons-label">@item.Text</label></div><button type="button"
id="@item.Value"
class="inputBtn btn btn-secondary"
data-toggle="modal"
datatarget="#@item.Value"
style="background-color: transparent; border-color: transparent; color: #007bff; font-size: 21px;"><i class="fa fa-question-circle"></i></button></span>
</wizard-step-content>
</wizard-step>And here's my attempt at setting up event listeners
var inputButtons = document.querySelectorAll(".inputBtn");
console.log(inputButtons);
console.log(inputButtons.length);
var buttonsCount = inputButtons.length;
for (var i = 0; i <= buttonsCount; i += 1) {
inputButtons[i].addEventListener("click", function(e) {
console.log("HI");
});
}

Hi!
I'm on the Material Main theme. The Kendo controls are already cozy-sized, and the material theme adds too much whitespace everywhere.
I'm struggling with the columns and header text alignment. As per the image, I cannot get either these headers or the cells to align correctly, and there is too much padding margin on the left.
@(Html.Kendo().Grid(Model)
.Name("gridLetters")
.Columns(columns =>
{
columns.Bound(p => p.Id).Filterable(false).Sortable(false).Width(60)

columns.Bound(p => p.Subject);
columns.Bound(p => p.CompanyName).Title("Company");

Hi there
I'm trying to add column menu to my grid but I need to do the following:
1) Add the three dots to the grid toolbar not to each column
2) I need once I click on the apply button to extend the functionality and run some js code, but I can't find any documentation for init, columnMenuOpen or any other event for ColumnMenu for .net core library.
Thanks

Hello! I have been troubleshooting an issue with the way that the treeview places elements. It appears to only be happening with items that contain children (and thus have an expand arrow).
I am unsure what could be causing this, but the library seems to be putting a span with the k-icon and k-i-expand classes (which will show the expand arrow) and then nesting the rest of the treeview row inside of that span. When I look at the demos of the same version on your site, the spans are not nested. Also I noticed that the css class names are different, but that might be on purpose (or perhaps I am confused about something).
<!-- HTML OF TREEVIEW ROW WITH CHILDREN -->
<li role="treeitem" class="k-item" data-uid="900b9f8a-e745-4d2f-9177-36f8f029d19a" aria-selected="false">
<div class="k-mid">
<span class="k-icon k-i-expand">
<span class="k-checkbox-wrapper" role="presentation">...</span>
<span class="k-in">...</span>
</span>
</div>
</li>
<!-- VERSUS HTML OF TREEVIEW ROW WITHOUT CHILDREN -->
<li role="treeitem" class="k-item" data-uid="dfd4e997-b440-42dc-8780-061f00ed16d6" aria-selected="false">
<div class="k-mid">
<span class="k-checkbox-wrapper" role="presentation">...</span>
<span class="k-in">...</span>
</div>
</li>Honestly, I am pretty stumped on this one.. as far as what could be causing this. I looked through the css classes in inspector and nothing stood out to me... I *AM* using a template though, but I don't see how it could be the issue. Here is the treeview definition as well as the template I am using:
<!-- GRID DEFINITION -->
<div class="d-flex flex-row">
@(Html.Kendo().TreeView()
.Name("TreeView")
.DataTextField("Name")
.Checkboxes(true)
.DragAndDrop(true)
.Events(events => events
.Select("treeview_OnSelect")
.Check("treeview_OnCheck")
.Drag("treeview_OnDrag")
.Drop("treeview_OnDrop"))
.TemplateId("treeview-template")
.DataSource(dataSource =>
dataSource.Read(read =>
read.Action(Model.ReadAction, Model.Controller)))
)
</div>
<!-- TEMPLATE -->
<script id="treeview-template" type="text/kendo-ui-template">
# var id = item.id; #
# if (id.includes("group")) { #
<i class="far fa-fw fa-folder"></i>
# } else if (id.includes("category")) { #
<i class="far fa-fw fa-sitemap"></i>
# } else { #
<i class="@Model.IconClass fa-fw"></i>
# } #
#: item.Name #

I'm running into a new issue with the UI for ASP.NET Core's Wizard in that if I add a code block, e.g., a @if statement or a @Localizer within a <wizard-step-content> tags, it will cause the stepper along the top not display. What are my options - I'll need the @if statements work in order to have certain information appear depending on what issue the user is submitting.
