Is there a way to change the title of the "Export to Pdf" button for localization purpose for example.

Hi,

We are looking to asynchronously upload a file and temporarily store it in the AppData folder. The widget works perfectly when uploading pdf files, but for some reason it triggers a full postback when we try to upload a jpg file.

For context, here are some code snippets from the view and controller:

View

@(Html.Kendo().Upload().Name("uploadDocuments")
          .Async(a => a
              .Save("Upload", "Home")
              .AutoUpload(true)))

Controller

public ActionResult Upload(HttpPostedFileBase[] uploadDocuments)
        {
            foreach (var document in uploadDocuments)
            {
                var fileName = Path.GetFileName(document.FileName);
                var uploadPath = Server.MapPath("~/App_Data");
                var physicalPath = Path.Combine(uploadPath, fileName);
                document.SaveAs(physicalPath);
            }

            // Return an empty string to signify success
            return Content("");
        }

We're using Kendo for ASP .NET MVC version 2017.2.621. Any help is greatly appreciated.

Thanks!

Hi,

I am working on Asp.Net MVC Grid (MVC 5 2017.1.223)  Please see the below code details.

@(Html.Kendo().Grid<EditableTest>()
        .Name("Grid")
        .Columns(columns =>
        {
            columns.Bound(c => c.testID).Hidden();
            columns.Bound(c => c.testDesc).Title("City Description");
            columns.Bound(c => c.testCode).Title("Country");
            columns.Command(command => { command.Edit(); command.Destroy(); }).Width(250);
        })
        .ToolBar(toolbar => { toolbar.Create(); })
        .Editable(ed => ed.Mode(GridEditMode.PopUp))
        .Sortable()
        .Pageable(pageable => pageable
            .Refresh(true)
            .PageSizes(true)
            .ButtonCount(5))
        .Filterable()
        .DataSource(dataSource => dataSource
            .Custom()
            .PageSize(20)
            .Schema(schema => schema.Model(m => m.Id(p => p.testID)))
            .Transport(transport =>
            {
                transport.Read(read => read.Url("http://localhost:60018/api/testapi").DataType("json"));
                transport.Create(create => create.Url("http://localhost:60018/api/testapi").Type(HttpVerbs.Post).DataType("json"));
                transport.Update(Update => Update.Url("http://localhost:60018/api/testapi").Type(HttpVerbs.Put).DataType("json"));
                transport.Destroy(del => del.Url("http://localhost:60018/api/testapi").Type(HttpVerbs.Delete).DataType("json"));                
            })
        )
)

This is custom Grid with web api. Read and create is work fine but update and destroy is not working. Is there any missing code. I understand for Put and Delete need to pass parameter thru web Api. I think I already added scheme for ID.  Appreciate your help on this. :)

Hi,

I've a kendo grid with a delete option for each row. Delete an item and it is removed from the list and the dete from the data context performs successfully. However when I delete another row, it tries to perform the delete of the first deleted row a 2nd time, cant find the entity and throws an error, so the 2nd item is not deleted.

Code as follows -

View

Server-side -

I've read up on it and it seems I need to return a success indicator to the grid but I cant work out how to do this in an mvc setup.

Any help greatly appreciated.

How can I specify the id of the record as an optional parameter in the UrlAction?

My website was working fine till last week, during which there seems to have been a chrome update.

The issue is right when my page loads, we have a search field, but the cursor does not display, even after i click with mouse pointer on the text box. I am able to type and do search, but the cursor does not appear, which says there is something wrong.

But once inside, I have another masterpage and here there are few jQuery validations. But even after the user enters the required values, keep getting "Those values required" error message. We use jquery validate, but even after we tried kendo validator the same issue remains. I cannot proceed from this page.

Once i close the browser and come back, the issue seems to be resolved some time. But its very inconsistent and we cannot suggest that to production. FireFox has no issues, so its something related with Chrome.

If i am loading the page in developer mode (F12), there seems to be no issue too. This happens only in the deployed version and right after clearing the cache of the browser. It has to be do with some scripts not loading, but I am not able to test it since, all scripts are loaded and working when doing it in developer mode.

I have a treeview set up as below ("treeview"), and the rendered checkboxes are not styled according to the theme (bootstrap).  If I set up another treeview with local data ("treeview1"), they render as themed.  Any hints as to how i can get the checkboxes to adhere to the theme when using a datasource?

NOT THEMED:

@(Html.Kendo().TreeView()
        .Name("treeview")
        .Checkboxes(checkboxes => checkboxes.Name("checkedCategories")
        .CheckChildren(true))
        .Events(events => events.Check("onCheck"))
        .DataTextField("description")
        .DataSource(dataSource => dataSource
            .Model(m => m.HasChildren("HasChildren").Children("Children"))
            .Read(read => read.Action("GetFilters", "ProductList")))
          )

THEMED:

@(Html.Kendo().TreeView()
        .Name("treeview1")
        .Checkboxes(checkboxes => checkboxes.Name("checkedCategories"))
        .Items(treeview =>
       {
           treeview.Add().Text("Asset Class").Id("1-1")
               .Expanded(true)
               .Items(category =>
               {
                   category.Add().Text("My first thing").Id("2-1");
                   category.Add().Text("My Second Thing").Id("2-2");
               });
       }))

Hi, 

I have created an ASP.NET MVC c# project and I have added two grids using the hierarchy option.  parent grid contains Orders Header records and child grid contains Orders details records, into grid child we need to use an telerik autocomplete mvc control here start the problem because is not working.  The two grids has been created using Razor syntax into the view, and the idea is create a CRUD into Parent Grid and into Child Grid, I mean when  you create a new header row (parent grid) you can add rows into child grid (master - detail behavior)

Using Column.Bound() into child grid, I have tried to use the ".Template" and ".ClientTemplate" method and even EditorTemplateName (using other cshtml view) but is not working.  Please note the autocomplete control must be visible when you create a new record or edit old record in detail grid.

What is the best way to do this task?

Any help, many thanks.

Hi,

I am using http://demos.telerik.com/aspnet-mvc/upload/chunkupload to upload video file around 2 GB using chunk of 10 MB, all setting in config has been done.

It worked on Firefox, Chrome and IE with no issue, great tool.

But when I tried to upload using safari on windows 10 OS, the same code do not worked and it seems it is in infinite loop and file size keeps increasing...

Config setting is as below:

 <httpRuntime targetFramework="4.5" maxRequestLength="2147483647"/>

<security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="2147483647"/>
      </requestFiltering>
 </security>

.cshtml:

@(Html.Kendo().Upload()
    .Name("files")
    .Async(a => a
        .Save("ChunkSave", "Upload")
        .Remove("Remove", "Upload")
        .AutoUpload(true)
        .ChunkSize(20000000) // Will separate the file into chunks of size 1100 bytes.
        .Concurrent(true) // Will upload all files simultaneously.
        .AutoRetryAfter(300) // Will attempt a failed chunk upload after 300ms.
        .MaxAutoRetries(4) // Will attempt the same failed chunk upload 4 times.
    )
)

C# code:
  public void AppendToFile(string fullPath, Stream content)
        {
            try
            {
                using (FileStream stream = new FileStream(fullPath, FileMode.Append, FileAccess.Write, FileShare.ReadWrite))

                    using (content)
                    {
                        content.CopyTo(stream);
                    }

            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(metaData));
            var serializer = new DataContractJsonSerializer(typeof(ChunkMetaData));
            ChunkMetaData chunkData = serializer.ReadObject(ms) as ChunkMetaData;
            string path = String.Empty;
            // The Name of the Upload component is "files"
            if (files != null)

                    path = Path.Combine(Server.MapPath("~/App_Data"), chunkData.FileName);

                    AppendToFile(path, file.InputStream);
                }
            }

            FileResult fileBlob = new FileResult();
            fileBlob.uploaded = chunkData.TotalChunks - 1 <= chunkData.ChunkIndex;
            fileBlob.fileUid = chunkData.UploadUid;

            return Json(fileBlob);
        }


        public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments)
        {
            //The Name of the Upload component is "attachments".
            foreach (var file in attachments)
            {
                //Some browsers send file names with a full path. You only care about the file name.
                var fileName = Path.GetFileName(file.FileName);
                var destinationPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);

                file.SaveAs(destinationPath);
            }

            //Return an empty string to signify success.
            return Content("");
        }

Can any one help me if I did something wrong?
