Bug report

Regression introduced in R2 2020. Possibly related to #5467

Reproduction of the problem

  1. Set up a ComboBox that uses virtualization:
<input id="orders" style="width: 100%" />

<script>
    $(document).ready(function() {
        $("#orders").kendoComboBox({
            dataTextField: "ProductName",
            dataValueField: "ProductID",
            virtual: {
                itemHeight: 26,
                valueMapper: function(options) {
                    $.ajax({
                        url: "Home/Orders_ValueMapper",
                        type: "GET",
                        dataType: "json",
                        data: convertValues(options.value),
                        success: function (data) {
                            options.success(data);
                        }
                    })
                }
            },
            height: 520,
            dataSource: {
                transport: {
                    read: {
                        url: "Home/Virtualization_Read",
                        dataType: "json" 
                    }
                },
                schema: {
                    model: {
                        fields: {
                            ProductID: { type: "number" },
                            ProductName: { type: "string" },
                        }
                    },
                    data: "Data",
		    total: "Total"
                },
                pageSize: 80,
                serverPaging: true,
                serverFiltering: true
            }
        });
    });

    function convertValues(value) {
        var data = {};

        value = $.isArray(value) ? value : [value];

        for (var idx = 0; idx < value.length; idx++) {
            data["values[" + idx + "]"] = value[idx];
        }

        return data;
    }
</script>
  1. Return an empty collection:
public ActionResult Virtualization_Read([DataSourceRequest] DataSourceRequest request)
{
    return Json(GetProducts().ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
}

public IEnumerable<Product> GetProducts()
{
    var products = Enumerable.Range(0, 0).Select(i => new Product
    {
        ProductID = i,
        ProductName = "ProductName" + i
    });

    return products;
}
  1. Focus the ComboBox input and press Down Arrow

Current behavior

A request to the Read action is sent with the following parameters:
http://localhost:54962/Home/Virtualization_Read?take=0&skip=NaN&page=NaN&pageSize=0&filter%5Blogic%5D=and

The NaN value of the parameters: skip=NaN&page=NaN causes a server error:

Input string was not in a correct format.
...
[Exception: NaN is not a valid value for Int32.]

Expected/desired behavior

No exception should be thrown. In versions prior to R2 2020 a request is not sent to the server on pressing Down arrow key.

Bug report

Reported in Ticket ID: 1529288

Reproduction of the problem

Create an MVC application:

View:

@{
	ViewBag.Title = "Home Page";
	string sfile = System.IO.Path.Combine(Server.MapPath("~"), "File1.xlsx");
}

@Html.Kendo().Spreadsheet().Name("spreadsheet"))

<br />	
<br />	
<button class="k-button k-primary" id="export" onclick="ExportExcel()">Export Spreadsheet content</button>
<script>
    function ExportExcel() {
        var spread = $('#spreadsheet').getKendoSpreadsheet();
        var data = JSON.stringify(spread.toJSON());

        var fd = new FormData();
        fd.append('wbook', data);
        fd.append('sfile', "File1.xlsx");

        $.ajax({
            url: "@Url.Action("SaveFileExcel", "Home")",
            data: fd,
            contentType: "application/x-www-form-urlencoded",
            processData: false,
            contentType: false,
            type: "POST",
            statusCode: {
                200: function (xhr, status, err) {
                    console.log('File exported!');
                },
                500: function (xhr, status, err) {
                    console.log('Internal Server Error!');
                }
            }
        });
    }
</script>

Controller:

[HttpPost]
public ActionResult SaveFileExcel(string wbook, string sFile)
{
    var workbook = Telerik.Web.Spreadsheet.Workbook.FromJson(wbook);
    string physicalPath = Path.Combine(Server.MapPath("~/"), sFile);
    //workbook.Save("C:/inetpub/wwwroot/" + sFile
    workbook.Save(physicalPath);
    return new EmptyResult();
}
  1. Add the application to a Docker container.
  2. Place a breakpoint in the SaveFileExcel action.
  3. Run the app and click the button below the Spreadsheet.

Current behavior

The Save method throws System.ExecutionEngineException

Expected/desired behavior

The file is saved.

The messages is available to be changed live in JS which is fine, but would be much more handy to have it exposed in the MVC wrapper at time of configuration

Enhance Filter Multi to support value and text and to allow server filtering. It would help avoid performance issues in scenarios that involve loading thousands or hundreds of thousands of records in the Filter.

Right now the Telerik UI MVC NuGet package is a 30 MB package that installs not just the DLL, but a lot of boilerplate JavaScript and CSS. I prefer to acquire the necessary content via Bower, so I can only install what I need.

Currently, after every upgrade I have to wait for the package to install, then delete all of the unused content files. It would be nice if you supplied an "assembly-only" package, moving the content into an optional package that users who still need it could install. It would reduce upgrade time substantially, as well as offer less chance for a mistake.

It would be nice if the MVC Definition of the Editor HtmlHelper (ImageBrowser and FileBrowser) provides the Path setting as demonstrated for the Kendo UI variation:

Just like posted here (and declined) : http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/3844570-serialization-support-of-datasourcerequest-and-app

I would like to see a portable separate assembly that : 
- can be referenced both on ASP.NET MVC side and WCF server side.
- A DataSourceRequest and DataSourceResult class that serialize well in both SOAP and REST WCF.

Referencing Kendo from the Application server side also requires references to System.Web.Mvc, Razor pages, ... and others that shouldn't be necessary.

Row's hover effect should be optional and it could be enabled/disabled in grid's configuration, the same as we add Selectable, Navigatable, Sortable, Editable, etc., functionalities to grid. This could apply to odd/even coloring too. Should no need to do hacks to achieve this.

I have many pictures to show. The ImageBrowser-Control has some kind of support for lazy loading. The problem is just that the thumbnail of items scrolling into the viewport are not loaded.

In the Kendo UI for jQuery Grid, fields that are not editable are displayed as text (no input elements) in the Grid's popup editor. The MVC Grid displays all fields that are present in the view model it is bound to in its popup editor.

Implement an option to configure the editable fields, so that the behavior of the MVC Grid matches that of its Kendo UI counterpart.

Today, when we use IEnumerable<dynamic> type as the model for the kendo grid, the grid is generated fine, but the javascript serialization fails when we pass the datasource to the GridBuilder constructor.
This results in empty grid client side, because the datasource is empty, even if the html initially generated contains the values.

This behavior comes from a problem with the JavaScriptSerializer (also present in the JSon() function of MVC)

If you change the dataSource to a grid (for example by changing the filter conditions) so that less data is returned, you will not be warned if the current page is no longer valid. No error is reported and no data is returned and you won't have a clue why.

Try this to replicate:

Make a paged grid plus a couple of datepickers to filter the grid data by date range. Add a button to make the new filter dates effective.

Write a new MVC controller method to populate the data, using the ToDataSourceResult extension method e.g. "return Json(obj.ToDataSourceResult(request));" to return data.

Open a sizeable dataset in the grid (many pages) and go to the last page.

Change the filter conditions to be much more restrictive. Click the button to make them effective.

Watch as the grid displays no data, the code reports no error and stepping into your controller confirms that the method is returning data.

Confusing huh? An error or warning would make this much clearer.

The existing solution was built in 2009 using .Net 3.5 web forms framework (List View), ASP.Net Ajax (Accordion) and JQuery (validation). 

The web page accomplishes the following key functional requirements –

a.	Ability to group products – The groups are dynamically extracted from the same datasource that is providing the product list.  Using ASP.Net Ajax we were able to provide the expand / collapse visual effect.

b.	Ability to enter order quantities very quickly -  a lot of stores place orders at the last minute  (5-10 minutes before order deadline) for valid reasons.  The web page readily provides a text box for quick entry.  On a desktop, the user can traverse the rows within the group using the tab key.   The web page typically contains 150 –  200 products for entry.  

Having to click on Edit/Update/Cancel dramatically increases the number of clicks / touch / swipe.  Besides, it creates a real estate issue on smaller form factors.  

c.	Real time validation – using JQuery we were able to validate the row as and when the quantity was entered.  Any error would show below the row in question.  The error would continue to show until the quantity was revised.  The error however, will not stop the user from entering quantities on other rows.  This approach lets the user review any errors in the end.
