Hi Team,

I already have a developer license for my project. It is going to expire soon. So, i have renewed my license from Telerik portal. Now, after renewal, what are the steps to be followed in Visual studio to update the renew License.

I am using Kendo.MVC components. 

Your inputs will be greatly helpful to move further

I have a page that has a pie chart and a grid. Both controls use the same data. I could create a data source for each control and have it call the service twice, but that seems inefficient. Is there a way to define the data source for the chart and handle an event when the data is returned and assign the data to the grid's data source?

Which event should be handled?

What's the command to assign the data to the grid's data source?

Thanks

Tim

I'm trying to add drag and drop functionality on my Grid. I have followed the documentation here, https://demos.telerik.com/aspnet-mvc/grid/drag-drop. However, I'm getting an gridreorderingsettingsbuilder does not contain a definition for 'Rows'. I'm also getting another error on .Draggable.  I'm using version 2021.1.224.545. Do I need to update my version?

                .Columns(columns =>

How can I return a Custom error for a Grid Operation.

E.g.: If the database delete is not possible show a popup that something is gone wrong.

Controller Method:
[HttpPost]
public ActionResult DestroyEmploymentStatus([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]List<EmploymentStatusViewModel> employmentStatuses)
{
    if (employmentStatuses.Any())
    {
        foreach (var esvm in employmentStatuses)
        {
            var es = db.EmploymentStatuses.Find(esvm.Id);
 
            db.EmploymentStatuses.Remove(es);
            db.SaveChanges();
        }
    }
 
    return Json(employmentStatuses.ToDataSourceResult(request, ModelState));
}

Hi,

i'm trying to use Kendo Upload to upload a file, using the selection or drag&drop, with file name length over 260 characters but the result of upload operation change the file name.

For example:

C:\Espropri e Patrimonio\Patrimonio\Tutela 2022\AAAAA\FASCIA DI RISPETTO\BENESTARE\CARTACEO-INFORMATICO\VAILOG (Conferenza Servizi AAAAA Italia Transport)\DOCUMENTAZIONE INFORMATICA-CARTACEA\RIPRISTINO\13.05.2022 Prot. ent. AAAAA (progetto)\Document timestamp signed.pdf.tsd.p7m

The file name change into "DOCUME~1.P7M".

I've reproduce the problem also with the demo at https://demos.telerik.com/kendo-ui/upload/initialfiles.

Is there a way to solve the problem?

Cchecking the API I do not see that the property "name" but also in this case the name of the file is "DOCUME ~ 1.P7M"

https://docs.telerik.com/kendo-ui/api/javascript/ui/upload/configuration/files#files.name

 

Many thanks

Stefano

There's something going on with this datetime picker.

Please see screenshots below. 

The item.DEFAULT_VALUE below has a value, not null.

But in the script below, the "value=" field is missing.

While others have "value=" field.

What's going on here?

My kendo UI version for ASP.NET MVC is 2022.2.621

A while ago I created a kendo.custom.min.js file for a project with the custom download builder. Unfortunately I did not make note of the options that were checked. Now I want to add a few Telerik controls to the project and create a new custom download file. Is there any easy to work backwards from a custom download file to find all of the options it contains?

Thanks

Hello Guys,

I have a grid with a start and end date and would like to select several start date cells and make an adjustment in the top selected start date cell and then all selected cells should be overwritten.

Thanks in advance!

I have an existing dropdownlist which gets its data via ajax from api.

Now, I want to add an item "Add New" (just under the existing optionlabel) , which when clicked will open a kendo window.

Questions:

1. First of all, is there any easy/direct way to do this?

2. One option that I could think of - and I am trying to get that working - is to add an item after the initial ajax data is loaded, and use onSelect to check if the option selected is "Add New" and open a window

However, I am not able to implement this. I am stuck at trying to add an additional item to the existing options (which as I mentioned is retrieved via ajax). How to do this? Please note that I already have a optionlabel which I want to retain (based on clients insistence).

 

Any idea how to achieve this?

 

PS: i cannot add this from server side api as that code is not in my control.

We have a Kendo grid that can display anywhere from 10 to thousands of rows.  We want to be able to set the grid page size to several values, including ALL.

What we have now - without ALL works:

.Pageable(p => p
     .PageSizes(new[] { 100, 200, 500, 1000, 2000 })

When we run this - we see the correct values in the "Items per page" dropdown.

We want to add the "All" option to this dropdown, but the following is not working (compile error)
.Pageable(p => p
     .PageSizes(new[] { 100, 200, 500, 1000, 2000, "All" })

How do we include All along with other values in the Items per page?
