a model is returned to the form in which parameter "Raion" bool has a value of true or false.
How to make it so that CheckBox itself takes the required value?

@(Html.Kendo().CheckBox().Name("Raion").Label("Выезд на район"))

public class ServiceViewModel
    {
*****
        public bool Raion { set; get; }
****
    }

@model service.Models.ServiceViewModel
@(Html.Kendo().CheckBox().Name("Raion").Label("Выезд на район"))

Good afternoon,

I've successfully managed to use PdfProcessing in a similar way to the demo but I want to include some error capture.  What's the best way to return the error to the View and display it e.g. if the file doesn't exist?

[HttpPost]
public ActionResult Download_Document()
{
    try
    {
        PdfFormatProvider formatProvider = new PdfFormatProvider();
        formatProvider.ExportSettings.ImageQuality = ImageQuality.High;

        byte[] renderedBytes = null;
        using (MemoryStream ms = new MemoryStream())
        {
            RadFixedDocument document = CreatePdfDocument.CreateDocument();
            formatProvider.Export(document, ms);
            renderedBytes = ms.ToArray();
        }

        return File(renderedBytes, "application/pdf", "PdfDocument.pdf");
     }
     catch (Exception e)
     {
         return e.Message;
     }
}

Kind regards,

Richard

HI,  

I am working on the MVC.net (not core) application.  used the few stuff from Kendo ui, like autocomplete and notification.  Everything works fine on local and when deployed to the Azure without the automated CI/CD process.

Now when it came to the do the build for CI/CD I am getting the below error:

ResolveAssemblyReferences: Primary reference "Kendo.Mvc". ##[warning]C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(2203,5): Warning MSB3245: Could not resolve this reference. Could not locate the assembly "Kendo.Mvc". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(2203,5): warning MSB3245: Could not resolve this reference.

[D:\a\1\s\MyApp\MyApp.csproj] For SearchPath "{HintPathFromItem}".

//Properties in Visual Studio for the dll

Although the code is running fine after deployment and on local but I noticed that the Telerick or Keno dlls that are sever in reference folder

are missing from the Package folder.

I am trying to use Kendo Grid in a razor view.
I have reference for the required css and js files in bundle.config:

bundles.Add(new StyleBundle("~/Content/kendo/css").Include(
               "~/Content/kendo/kendo.common.min.css",
               "~/Content/kendo/kendo.common-bootstrap.min.css",
               "~/Content/kendo/kendo.bootstrap.min.css"
               ));
            bundles.Add(new ScriptBundle("~/Scripts/kendo/js").Include(
                    "~/Scripts/kendo/jquery.min.js",
                    "~/Scripts/kendo/kendo.all.min.js",
                    "~/Scripts/kendo/kendo.aspnetmvc.min.js"
                ));

In the View I have this:

@using Kendo.Mvc.UI;
@using Kendo.Mvc.Extensions;

@model WebApplication.Models.TMS_Categories

@{
    ViewBag.Title = "Index";
}



<h2>Index</h2>

<div class="container">

I need to add default values for dropdown tree

After clicking of create button on above sample provided code

A security scan caught security vulnerabilities on several javascript files included with ASP.NET MVC version 2021.3.1109:

Can I safely exclude these files from my project?

Thanks.

I have configured an Upload control as an Async Single File (multiple = false) upload as shown below.  When I drag-n-drop multiple files (e.g., three files) into the drop zone, one of the files is uploaded. Which of the files gets uploaded seems a bit random. It's confusing to the users that they can drop multiple files and only one gets uploaded.

I thought I could could check the event parameter passed into the Upload or Success events to see if e.files length is greater than one and if it is, do a e.preventDefault() and display a warning message. However, the e.files contains only one of the files that were dropped (e.g., I drop three files and the e.files.length is one). How do I determine if multiple files were dropped?

@(Html.Kendo().Upload()
      .Name("attachments")
      .Multiple(false)
      .ShowFileList(true)
      .Async(async => async.Save("Save", "Upload").AutoUpload(true))
      .Events(events => events.Error("onError").Success("onSuccess").Upload("onUpload").Select("onSelect")))

The kendo Grid Column datatype is string

columns.Bound(c => c.StartDate).Title("Start date").Format("{0: dd/MM/yyyy}").Filterable(f => f.Cell(c =>c.ShowOperators(false).Operator("contains").SuggestionOperator(FilterType.Contains)));

I am able to change the datatype of the Kendo Grid column from string to Date.

.DataSource(dataSource => dataSource

.Ajax()

.Model(model =>

    {

        model.Id(p => p.ID);

       model.Field("StartDate", typeof(DateTime));

 })

but the issue i am facing is, if the value of the string like "23/03/2020" or "15/06/2021", then no value will be displayed in the cell of the "StartDate" column of the Grid.

please help me to resolve the issue.

Hi,

as I see in the following demo it says it is loading the partial views in Tabs, not a Main View:

https://demos.telerik.com/aspnet-mvc/tabstrip/ajax

In the example they loaded different partial views in tabs like,  ajaxContent1.html, ajaxContent1.html, ajaxContent1.html.

Q1. But can I load same partial view (ajaxContent1.html) in 3 different tabs?

Q2. Can I load View other than Partial View in a Tab?

I'm following this video tutorial:
