I'm in the process of upgrading an existing MVC 5 application to Core 2. Kendo UI Grid is used to display documents and has the Kendo Upload control added to the toolbar of the Grid.

This works fine in the MVC 5 implementation as shown below:

 @(Html.Kendo().Grid<ViewModels.Documents>()
      .Name("filesGrid")
      .ToolBar(t => t.Template(
        @<text>
    )
            @(Html.Kendo().Upload()
                  .Name("files")
                  .HtmlAttributes(new { aria_label = "files" })
                  .Async(a => a.Save("DocumentSave", "Home", new { requestId = ViewBag.RequestId }))
                  .Events(e => e.Success("onUploadSuccess"))
                  .ShowFileList(false) // Hide the file list as we're displaying uploaded files in the Grid
            )
        </text>
      ))
      .Columns(columns =>
      {
          columns.Bound(f => f.FileName).ClientTemplate(Html.ActionLink("#=FileName#", "Download", "Home", new { id = "id" }, null).ToHtmlString().Replace("id", "#=DocumentId#")).Title("File name");
          // Calculate the file size in KB, round it up and display it in a client template
          //columns.Bound(f => f.DataLength).ClientTemplate("#= Math.ceil(DataLength / 1024) #").Title("File size in KB").Width(150);
          columns.Bound(f => f.DataLength).Title("File size").Width(150);
          columns.Command(command => command.Destroy()).Width(100);
      })
      .Sortable()
      .Pageable()
      .DataSource(dataSource => dataSource
          .Ajax()
          .PageSize(10)
          .Model(m => m.Id(f => f.DocumentId))
          .Read(read => read.Action("DocumentsRead", "Home", new { requestId = ViewBag.RequestId }))
          .Destroy(update => update.Action("DocumentDelete", "Home"))
      )
    )

However in ASP.NET Core 2 KendoUICore 2018.1.117, the .ToolBar(t => t.Template() method is no longer available, it appears it has been replaced by ClientTemplate. When I attempt to embed the same markup for UI Upload inside ClientTemplate, I get an error "Cannot convert lambda expression to type 'string' because it is not a delegate type"

.ToolBar(t => t.Create()).ToolBar(toolbar =>
                    {
                      toolbar.ClientTemplate(@<text>Html.Kendo().Upload()</text>);
                    }
                    )

Thanks for the input!

Hello! I am using the exact same code as in this example: https://demos.telerik.com/kendo-ui/spreadsheet/datasource

When I try to add 1 validation like this:

sheet.range("$B2").validation({
                    from: '{ "Foo item 1", "Bar item 2", "Baz item 3" }',
                    dataType: "list",
                    messageTemplate: "Number should match the validation.",
                    showButton: true,
                    comparerType: "list",
                    type: "reject"
                });

it works fine and shows it with no problem, but when I add a second one, the headers are not shown and I get this error:

Uncaught TypeError: Cannot read property 'indexOf' of undefined
    at r.set (kendo.all.min.js:27)
    at r.set (kendo.all.min.js:27)
    at kendo.all.min.js:586
    at init.forEach (kendo.all.min.js:511)
    at init._sheetChange (kendo.all.min.js:586)
    at init.trigger (kendo.all.min.js:4)
    at init.triggerChange (kendo.all.min.js:526)
    at init._set (kendo.all.min.js:518)
    at init._property (kendo.all.min.js:518)
    at init.validation (kendo.all.min.js:521)

This is all the code I added to the example:

var spreadsheet = $("#spreadsheet").data("kendoSpreadsheet");

                var sheet = spreadsheet.activeSheet();

                sheet.range("$B2").validation({
                    from: '{ "Foo item 1", "Bar item 2", "Baz item 3" }',
                    dataType: "list",
                    messageTemplate: "Number should match the validation.",
                    showButton: true,
                    comparerType: "list",
                    type: "reject"
                });

                sheet.range("$C2").validation({
                    from: '{ "Ble item 1", "Ble item 2", "Ble item 3" }',
                    dataType: "list",
                    messageTemplate: "Number should match the validation.",
                    showButton: true,
                    comparerType: "list",
                    type: "reject"
                });

Please help! thanks

Hi,

I have a Kendo Drop down, displaying remote data (of type odata) implemented as follows:

    $("#listDropDown").kendoDropDownList({
        filter: "contains",
        dataTextField: "displayName",
        dataValueField: "fieldid",
        optionLabel: "Please Select..."
        dataSource: {
            type: "odata-v4",
            transport: {
                read: function (options) {
                    $.ajax({
                        url: someURL,
                        dataType: "json",
                        success: function (result) {
                            options.success(result);
                        },
                        error: function (result) {
                            console.log(result);
                        }
                    });
                }
            } 
        }
    });

the 'fieldId' in this case is of type GUID. The drop down is created successfully and displaying data on screen. Using the no data template i can also successfully add a new item and refresh the drop down to the item is available on the list. 

I would like to dynamically set the selecteditem on the drop to the item that has just been added. I am using the following code. 

 $("#listDropDown").data("kendoDropDownList").value(newFieldId);

'newfieldId' is a GUID that has been returned by the ajax call which has just created the new item. This is getting a value successfully, however doesnt appear to work. I have also tried hard coding this to use a value which i know existsin the drop down which i pass in as a string as i would expect a GUID to and this still doesnt work. This leads me to believe i havent configured my drop down correctly for using the GUID as the datavalue field. 

Can you confirm if this is the case?

Many thanks

Hi,

We have one grid in which we have one column for every day between two different dates, it works fine with one year but fails when we have more than one, you could see the error into this Dojo (https://dojo.telerik.com/asIVaS/2). It works with our previous version (2017R2SP1) but fails with newest ones. It looks like there are one error into rowtemplate. There is something wrong or any workaround to skip that error?

Thanks in advance
