Hello Kendo UI team,

We are using Kendo UI for jQuery Spreadsheet and have encountered a border rendering issue that can be reproduced with a very simple setup and no custom configuration.


Reproduction steps

  1. Initialize a basic Spreadsheet with default options.

  2. Select the range A1:C3.

  3. Apply borders to the selected cells (for example, all borders).

  4. Select row 3 and delete the row.


Actual result

After deleting row 3:

  • The top border of cell B1 disappears.

  • Other borders remain unchanged.

  • The final border state becomes visually inconsistent and unexpected.

The attached screenshots (step1 → step4) show the full process and the resulting issue.


Expected result

  • Borders explicitly applied by the user should remain intact.

  • Deleting row 3 should not affect the top border of B1, since that cell is not part of the deleted row.


Request

Is there any solution or workaround for this behavior?

Thank you very much for providing such a powerful and well-designed UI library. We really appreciate the work behind Kendo UI and would love to continue using the Spreadsheet component.

If I import an excelfile, where cells have text with overflow into the next cell, the excel file will show the overflowing text. The spreadsheet editor is hiding overflowing text behind the following cell.

Is it possible to format the spreadsheet to show overflowing cell content like in excel?

I know, Excel is showing overflowing content only, if the following cells are ampty - but this is exactly what we face. There are a bunch of excelfiles to process in our application, where people didn't care about formating cells with overflowing content. We just want to show this content like excel.

I have a page which display simple value with this control & JS, appreciate anyone could correct my mistake below. Thanks.

*Remove all un-necessary code to simplified sample code

Javascript



kendo.culture("tr-TR");

<script src="@Url.Content($"/cultures/kendo.culture.tr-TR.min.js")"></script>

HTML

<span data-format="n2" data-bind="text: TotalCompletePrice" />

if less than 100K, the value display fine -->12.232,00

but, when the value over 100K it will display like below which is incorrect format

Wrong- 1.24.544,00
expected-124.544,00

I would like to add the culture code en-JP to be included in the next release? I created a .js file. Where do I submit it?
kendo.cultures["en-JP"] = {
    // <language code>-<country/region code>
    name: "en-JP",
    // The "numberFormat" defines general number formatting rules.
    numberFormat: {

Hi,

I have downloaded the zip file from telerik(Progress® Telerik® UI for ASP.NET MVC) site and used in my project. I have licensed version of telerik. I applied license in below approaches
1. Downloaded the key license .txt file and placed in the root folder of project and also added in system variables.
2. Downloaded the script license and placed in the project scripts, refereed in _layout.cshtml page.

Either of the approaches I am getting a warning  message at the top of my application while running the application.

message: both paid and trial usage. Learn how to set up a license key.

Please guide me how to setup license if I am missing something here.

I have an editor configured like this:

                @(Html.Kendo().EditorFor(m => m.MyTextData)
                    .Tag("div")
                    .Name("MyTextData")
                    .Resizable(x =>
                    {
                        x.Content(true);
                        x.Min(120);
                        x.Max(400);
                        x.Toolbar(false);
                    })
                    .StyleSheets(css => css.Add(Url.ContentVersioned("~/Content/EditorStyles.css")))
                    .Encode(false)
                    .Events(e => e.Change("onEditorChangeOfContent"))
                    .Tools(tools => tools
                        .Clear()
                        .Bold()
                        .Italic()
                        .Underline()
                        .JustifyLeft()
                        .JustifyCenter()
                        .JustifyRight()
                        .InsertUnorderedList()
                        .InsertOrderedList()
                        .InsertLowerRomanList()
                        .InsertUpperRomanList()
                        .Indent()
                        .Outdent()
                        .FirstLineIndent()
                        .SubScript()
                        .SuperScript()
                        .TableEditingWithCellBorder()
                    )
                )

When first clicking in the editor text area then clicking out of the text area without changing any of the text, the blur function is called and in the blur function a comparison is made between "value" and "old".  In this first call to blur, old is undefined so the match is not made and the change event is triggered as if the text was changed.  Note that if the same action of clicking in and out of the text area is done again, old contains the correct value and no change event is triggered, so it works differently the second time.  The change event should not be triggered on the first action as the text was not changed.

Here is the blur function in Kendo:

         _blur: function() {
                var textarea = this.textarea;
                var old = textarea ? textarea.val() : this._oldValue;
                var value = this.options.encoded ? this.encodedValue() : this.value();

                this.update();

                if (textarea) {
                    textarea.trigger("blur");
                }

                if (value != old) {
                    this.trigger("change");
                    if (textarea) {
                        textarea.trigger("change");
                    }
                }

I have a grid with a filterable cell. A translate pipe is used in its template - this causes that the filter does not work properly, as it recognizes the original values and not the translated ones.

        {
            field: "xxx",
            title: "foo",
            width: "120px",
            template: "{{ 'yyy' | translate }}",
            filterable: {
                cell: {
                    showOperators: false,
                    operator: 'contains',
                    suggestionOperator: "contains"
                }
            }
        },

Is there any way to get the filter values translated as well?

This question is similar to https://www.telerik.com/forums/grid---custom-filtering-function-for-a-particular-column, except that this is related to Kendo for jQuery.
