The built-in kendoDropDownFilter directive normalizes text using String.prototype.toLowerCase() when caseSensitive: false. This is locale-insensitive and produces incorrect results for languages with non-standard case-folding rules, most notably Turkish.

The correct fix is to use String.prototype.toLocaleLowerCase(locale), which respects locale-specific case rules. The DropDownFilterSettings interface should expose a locale option for this:

filterSettings = {
  caseSensitive: false,
  operator: 'startsWith',
  locale: 'tr-TR'   // ← proposed new option
};

Affected components: kendoDropDownFilter directive (used with AutoCompleteComponent, ComboBoxComponent, MultiColumnComboBoxComponent, DropDownListComponent, MultiSelectComponent).

Hi,

When both virtual scrolling and grouping are enabled via the kendoGridGroupBinding directive, and the Grid is navigable, focus is trapped in the header row when down or up arrow is pressed:

https://stackblitz.com/edit/angular-icxejq?file=app/app.component.ts

1. Focus any content cell

2. Press up/down - focus goes to the header cell of the respective column and is trapped in the header row

The example does not work:

https://www.telerik.com/kendo-angular-ui/components/tooltip/how-to/show-grid-cells-content/

I want to filter the scheduler data but I had to add the OwnerId property to the node package interface in order to be able to do so... yet the sample data provided in the examples does include the ownerId, so im guessing all that needs to be done is to add it to the interface.

Hi,

We encountered a problem when using kendo-sortable component in IE11. If we use this component anywhere on the page, all input fields on the page become unclickable. It seems to happen in the last version of this control (maybe because of a global click event listener? )

Hope you can help with this issue.

You can check out the following Stackblitz example which is based on your basic usage example: https://angular-t7vi5k.stackblitz.io/

Thanks in advance and happy holidays,

The manner in which the Kendo Grid handles multiple column sorting is unusual and therefore not what a user would expect.

I believe that people expect that the column they click on to always be the primary sort column.  In the Kendo grid, (when in multi-column mode) this is not the case.

If I click on the "Unit Price" column header, and then on "Product Name", nothing happens.  Instead, clicking on "Unit Price" a second time sorts the table by "Product Name".  This is not natural. 

Instead, this should simply behave like a non-destructive sort.  If I click on "Unit Price" and it sorts by that.  Then, clicking on "Product Name" should sort everything by Product Name and, if the names are the same, the items would be sub-sorted by the previously selected column: "Unit Price"

I would further ask that the only column that shows the arrow be the primary sort column.  Users want to see what the primary sort column is, and not be confused by the other columns, which they will assume are sorted in a reasonable way.  The indices help, but I still think that a single arrow denoting the primary sort column would be preferred.

https://www.telerik.com/kendo-angular-ui/components/grid/sorting/

To be backwards compatible, maybe introduce a 'natural' sort mode which would behave in this manner, since I really believe that this is what a user expect.

As a workaround, we put the grid in 'single' mode, and then when the sort changes, we do the following.  I limit the number of SortDescriptors to 3 as a compromise between sorting the columns in a reasonable way and yet prevent there from being too many arrows

public autoSortChange(sorts: SortDescriptor[]) {
   let singleSortKey = sorts[0];
   let newSort: SortDescriptor[] = [];
   newSort[0] = singleSortKey;
   this.internalSortDescriptors = this.internalSortDescriptors.filter(des => des.field !== singleSortKey.field)

   newSort = sorts.concat(this.internalSortDescriptors)

   this.internalSortDescriptors = Array.from(newSort);
   if (this.internalSortDescriptors.length > 2) {
    this.internalSortDescriptors.length = 2;
   }
   this.gridState.sort = newSort;
   this.gridData = ...
}

Reproduction

• Set the "scrollable" and "height" options of a grid.
• Add 0 or only a few rows.
• Also reproducable by removing rows from this stackblitz: https://www.telerik.com/kendo-angular-ui/components/grid/scroll-modes/#toc-scrollable-mode

Hello, I am trying to use the table-related toolbar tools in my editor. I am getting the compiler.js:2175 Uncaught Error: Template parse errors:

1. If 'kendo-editor-insert-table-button' is an Angular component, then verify that it is part of this module.
2. If 'kendo-editor-insert-table-button' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("               <!-- Kendo Built-In Toolbar tools not working correctly -->.

I have not had an issue with any other toolbar tools.

a. In "Show business hours" mode open event creating dialog and set start-end time that is outside of business hours specified, e.g. 07.00-07.30 when business hours are 08.00-20.00.

b. Press Save buttom.

c. Switch to "Show full day" mode.

Actual result - event is not shown.

Event appears only after, e.g. , pressing next arrow button and then pressing back arrow button.

1. Change scheduler timezone in combobox

2. Change view selector to "Month", for example.

Result: provided colors from resources aren't appied anymore.
