Scroll to current Date in TimelineMonth view

Hi,

Is there any examples where scheduler is automatically scrolled to current date, but for scheduler created in ASP.NET Core?

This is exactly what I need, but I can't make it work in my ASP.NET Core project: https://www.telerik.com/forums/scheduler-timelinemonth-current-day-visible

My rows.length are always 0, so is my contentDiv.length, when I checked it.

var scheduler = $("#scheduler").getKendoScheduler();
var contentDiv = scheduler.element.find("div.k-scheduler-content");
var rows = contentDiv.find("tr td");

for (var i = 0; i < rows.length; i++) {
var slot = scheduler.slotByElement(rows[i]);

var slotTime = kendo.toString(slot.startDate, "d");
var targetTime = kendo.toString(time, "d");

if (targetTime === slotTime) {
contentDiv.scrollLeft($(rows[i]).offset().left + contentDiv.scrollLeft() - contentDiv.position().left);
}
};

ColumnMenu doesnt work properly when using Template columns in the same Grid

I've had this issue for years with the Telerik grid when trying to use the built in ColumnMenu in the same grid as template columns. I want to make a template column for a custom button. The column and button work fine, however if the template column is not the last column in the grid it causes the ColumnMenu items to all be off by one. ie: you click one of the columns to hide it in the ColumnMenu and it will hide the one above it in the list instead. It's like the column menu doesnt know to account for the template columns.

The only workaround I've found is to place the template column as the last column in the grid or to make a bound column and set its title to a blank and set sorting/paging both false, however this still then leaves a blank entry in the column menu and is not desirable. Am I missing something when using template columns and the ColumnMenu in the same grid?

Code for my template column:

columns.Template("<button type=\"button\" class=\"btn btn-grid\" data-id=\"#=Id#\"><i class=\"fas fa-fw fa-pencil-alt\"></i></button>");

Heres is some code of a grid (I chopped a lot of code out of this grid to simplify it and verified this still has the issue), all of my grids across many projects share this issue. This grid is using version 2020.2.617 and the bootstrap theme.

@(Html.Kendo().Grid<TagGridViewModel>().Name("gridTags")
.Columns(columns =>
{
columns.Template("<button type=\"button\" class=\"btn btn-grid\" data-id=\"#=Id#\"><i class=\"fas fa-fw fa-pencil-alt\"></i></button>");
columns.Bound(c => c.TagId).Filterable(f => f.Cell(cell => cell.ShowOperators(false).SuggestionOperator(FilterType.Contains).MinLength(2))).ClientTemplate($"<a class=\"grid-link\" href=\"{Url.Action("Details", "Tags")}/#=Id#\">#:{nameof(TagGridViewModel.TagId)}#</a>");
columns.Bound(c => c.AddDate).Filterable(false);
columns.Bound(c => c.UpdateDate).Title("Updated").Filterable(false).ClientTemplate($"#={nameof(TagGridViewModel.UpdateDateDisplay)}#");
})
.ColumnMenu(true)
.DataSource(dataSource => dataSource.Ajax().PageSize(25)
.ServerOperation(false)
.Read(read => read.Action("DetailsTagsGridRead", "Clients", new { clientId = Model.Location.ClientId, locationId = Model.Location.Id }))
.Events(events => events.Error("gridError"))
)
)

Header in LayoutGrid: Mixing of Text() and TemplateId() leads to strange behaviour

Hello

when mixing Text() and TemplateId() for the headers in a LayoutGrid, it is working fine until Text() is used the first time. After that the header uses the content of the previous header.

The complete example (just copy / paste it):

<div class="demo-section list-wrapper">
<h3 class="title">
Reorder Items
</h3>
<script id="ll" type="text/x-kendo-template">
<ul>
<li class="list-left">Item 1</li>
<li class="list-left">Item 2</li>
<li class="list-left">Item 3</li>
</ul>
</script>

<script id="lr" type="text/x-kendo-template">
<ul>
<li class="list-right">Item a</li>
<li class="list-right">Item b</li>
<li class="list-right">Item c</li>
</ul>
</script>

<script id="header-template" type="text/x-kendo-template">
<strong>List 2</strong>
</script>

<script id="header-template-1" type="text/x-kendo-template">
<strong>Liste 1</strong>
</script>
</div>

@(Html.Kendo().TileLayout()
.Name("tilelayout")
.Columns(4)
.Containers(c => {
c.Add().Header(h => h.TemplateId("header-template-1")).BodyTemplateId("ll");
c.Add().Header(h => h.TemplateId("header-template")).BodyTemplateId("lr");
c.Add().Header(h => h.Text("Header for List")).BodyTemplateId("ll");
c.Add().Header(h => h.TemplateId("header-template")).BodyTemplateId("lr");
})
.Resizable()
.Reorderable()
)

I would expect for the headers:

- Liste 1

- List 2

- Header for List

- List 2

I get this:

The last one is wrong.

Of course, I can use TemplateId() for all of them.

If it is by design, add a note to the documentation, please.

Best regards

Christine

does any of your image control support to bind image from memory stream instead of Url

We are using telerik.web.ui (version 2010.2.713.35 ) controls for displaying results in data grid format in our ASP.Net web application .

GroupPaging in Custom Data Binding

Hello,

I am trying to have a groupable Kendo grid with help of your demo.

https://demos.telerik.com/aspnet-core/grid/grouppaging

My question is, is there a way to implement it with custom data binding and not ajax data binding? when I try to do that, there's an error saying that GroupPaging() cannot be resolved.

Thank you in advance.

Combobox - is autocomplete possible as in Ajax control?

In the Ajax control, you have the ability to filter a list and, if the term is not found, execute a command on the new term you typed in. This is in the Ajax demo at https://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/autocompleteclientside/defaultcs.aspx?_ga=2.149674102.1173080875.1622059656-840544784.1585530237 in the Autocomplete example at the top. I am not seeing this functionality replicated in the documentation for .NET Core. Is it possible to do something like this using a Tag Helper? If so, how would one go about it?

Thanks!

Laurie

p.s. For example, if I enter antoine@telerik.com (not found in the list), and click Submit, the message "You have selected the following email: antoine@teleri.com" will be displayed.
