Say I am uploading an Image - k-file-preview shows this link --> https://demos.telerik.com/aspnet-mvc/imagebrowser/thumbnail?path=thumbnail1.jpg
and upon insert the image into the editor the image url shows as --> https://demos.telerik.com/aspnet-mvc/content/userfiles/images/thumbnail1.jpg

does this mean we have thumbnails for the uploaded image stored in another folder, and upon calling thumbnail path it looks for the path n gives the preview??

then again for asp .net core i see k-listview-item i do not see a k-file-preview but on asp .net mvc and for jQuery I can see the thumbnail on demo -->  https://demos.telerik.com/aspnet-mvc/editor/imagebrowser

Hello good day.

I have a KendoGrid where there are two rows for each record, the first two fields are repeated, I would like to merge two cells and make a single row with them, but the rest of the fields belonging to those records remain in their two different rows.

I show how it looks right now:

I show how I want it to look:

Thank you so much.

Hi, I want to create a shared data source that I can then apply filtering to. This data source should be initialised from a property on the Razor page model.

With a Grid you can do this:

Html.Kendo().Grid(Model.Devices)

But I can't figure out the equivalent for the DataSource. This is not allowed...

Html.Kendo().DataSource<DeviceAggregate>(Model.Devices)
                .Name("devicesDataSource")

We have a custom command in a UI for ASP.NET Core FileManager control that states the icon as a simple textual name which worked fine in 2023.1.117

items.Add("").Type("button").Name("refresh").Icon("reload").Text("Refresh").Click("onRefresh").HtmlAttributes(new { style = "margin-left: 5px;" });

Hi All,
I have a problem. I've a not working grid. I do a compilated query for get the data but the data never gets loaded in the grid.

What is the error? Thanks in advance for any help.

I am relatively new to ASP.Net core (.net6) and I am trying to bind the Kendo scheduler with my existing data source.

Background: I am tasked with replacing outdated javascript tools for our "shipping scheduler", which is very similar to the Telerik Scheduler Timeline view.

Here is an example of what I am trying to achieve...

The data source is a simple API source from the web (for example https://mydomain.com/datasource), with the following structure:

namespace ShippingSchedulerApp.Models
{
    public class SchedulerEvent
    {
        public long ID { get; set; }
        public DateTime? start_date { get; set; }
        public DateTime? end_date { get; set; }
        public string? text { get; set; }
        public string? shipclass { get; set; }
        public decimal? beam { get; set; }
        public string? sectionID { get; set; }
        public string? flag { get; set; }
        public string? country { get; set; }
        public string? visitnumber { get; set; }
        public int? visitid { get; set; }
        public int? imo { get; set; }
        public string? details { get; set; }
        public string? cargo { get; set; }
        public decimal? duration { get; set; }
        public decimal? loa { get; set; }
        public string? stevedore { get; set; }
    }
}

If someone could point me to a demo or a sample way of connecting the above to the Telerik Scheduler Timeline view, that would be great.

Thanks

I find myself having a heck of a time getting started with the scheduler. Is there a SIMPLE getting started example that explains how to use the scheduler? All I am looking to do is to have a monthly view and be able to display availability of items. An item could be, for example, a room at a hotel. I won't be doing anything more granular than day level scheduling. I want to block out a date on the calendar for an item. That's it. Once I can figure out how to do that, I can dig deeper myself.

Any guidance would be greatly appreciated.

Hello,

I have a DropDownList that I would like to cache based on a radio button 

@(
                    Html.Kendo().DropDownList()
                        .Name("orders")
                        .DataTextField("Companies_name")
                        .DataValueField("CompaniesId")
                        .MinLength(3)
                    .HtmlAttributes(new { style = "width:25%" })
                        .Template("#= CompaniesId # |  #= Companies_name #")
                        .Height(520)
                        .Filter(FilterType.Contains)
                        .DataSource(source =>
                        {
                            source
                            .Ajax()
                            .PageSize(80)
                            .Read("Virtualization_Read", "NewUploadAccount");
                        })
                        .Events(e =>
                        {
                            e.Change("onChange");
                    })
                        .Virtual(v => v.ItemHeight(26).ValueMapper("valueMapper"))
                        )

I'm using ASP NET CORE.  I have a grid and I enable filtering on a column with .Filterable().  Is there a way to sort the items that appear in the checkbox filter?

EX:

My filter would look like this

• A
• B
• C

And not

• B
• C
• A

When the drop down is displayed.
