Hi there,

I'd like to trigger the virtualization scroll event programatically. My idea is to use a global body scroller to register the scroll down, and completely turn off the scroller on the listview container.

When I use the following code it will only replace my existing rows.

$("#allProductsListView").data("kendoListView").dataSource.read({ page: 2, pageSize: 36 })

I need a way to append in order to make virtualization work programatically.

Thank you.

I need grouping, filtering, sorting for a column. When I'm trying to bind to a field of an object which can be null, I get:

Uncaught TypeError: Cannot read properties of null (reading 'Name')

I am looking for a sample of a responsive pie chart. I have tried different suggestions from the forums but none seem to work. Is there a fully worked sample I can reference?

I have a situation where certain users should be able to view data in a grid, but not be able to edit it. It looks like there are ways to disable individual elements of the grid, but is there a way to make it entirely readonly?

[edit: of course as soon as I finished typing this a co-worker made a suggestion that works. Simply putting the grid in a div with the class k-state-disabled does the trick]

I have grid, which has a boolean column, I want after page loading, to show only records with true value of the boolean column. I'm using row filtering, and I also want to show filter controls for this column activated on true value. I turned off server operations.

Hello,

I am letting users to upload a pdf file on the browser. Once the user upload the file, I want to give them the option to view the uploaded file. In order to upload the file, I am using ASP.NET Core Upload Asynchronous Upload control and it works fine, but I am not sure how can I have the user view the pdf file as soon as it uploads. The files exists on server. Below is my entire code:

 


@using Kendo.Mvc.UI
<div style="margin-top:60px">
    <div>
        <span style="font-size:20px; font-weight:bold">Upload File</span>

    </div>
    <br />  <br />  
        <div class="block-section">
        @(Html.Kendo().Upload()
            .Name("files")
            .Async(a => a
                .Save("Async_Save", "Block")
                .Remove("Async_Remove", "Block")
                .AutoUpload(true)
            )
        )
    </div>


below is my controller code:


 public async Task<IActionResult> Async_Save(IEnumerable<IFormFile> files)
        {


            foreach (var file in files)
            {
                var fileContent = ContentDispositionHeaderValue.Parse(file.ContentDisposition);


                var fileName = Path.GetFileName(fileContent.FileName.ToString().Trim('"'));
                var physicalPath = Path.Combine(_webHostEnvironment.WebRootPath, "UploadedFiles", fileName);
                using (var fileStream = new FileStream(physicalPath, FileMode.Create))
                {
                    await file.CopyToAsync(fileStream);
                }

               
            }
            return Content("");
        }

The file that is uploaded by the user using the above control, I want the user to see that file. I know Telerik has pdfViewer, but I am not sure how the pdfViewer can show the file that exists on the server. The files is uploaded and saved on a folder in wwwRoot. i dont know the name of the file. Below is what I am trying to use:

 


 <div>
        @(Html.Kendo().PDFViewer().Name("pdfviewer")
            .PdfjsProcessing(pdf => pdf.File(Url.Content("~/wwwroot/UploadedFiles/2020-0598857.pdf")))
            .Height(1200)
            )

    </div>
but I  dont have the file name. User can name the file and upload it and I want the user to preview the file.

  public ActionResult Async_Save(IEnumerable<IFormFile> files)
        {
            // The Name of the Upload component is "files"
            string path = Path.Combine(_webHostEnvironment.WebRootPath, "FileSavePath");
            string DestinationPath = _configuration["DestinationPath"].ToString();
            if (files != null)
            {
                MoveFiles mf = new MoveFiles(); 
               
                foreach (var formFile in files)
                {
                    
                  

                    using (var stream = System.IO.File.Create(DestinationPath))
                    {
                        formFile.CopyTo(stream);
                    }

                    
                }
            }

This is my cshtml code:

@using Kendo.Mvc.UI
<div style="margin-top:60px">
        <div class="block-section">
        @(Html.Kendo().Upload()

            .Async(a => a
                .Save("Async_Save", "Upload")
                .Remove("Async_Remove", "Upload")
                .AutoUpload(true)

We are using Telerik for Asp.Net Core.  Using the file upload control in asynchronous chunk mode is there a maximum file size?  I know in synchronous mode its about 2gb, but I am curious if using chunk mode we can go past that since the file is uploaded in pieces.?
