i've tried to apply autoFitColumn method for treelist accordingly to the documentation, https://docs.telerik.com/kendo-ui/api/javascript/ui/treelist/methods/autofitcolumn#autofitcolumn , and seems it assumes only "simple" columns structure, i.e. no nested headers.

I'm getting inconsistent behavior when testing a ComboBox with Virtualization enabled. I've tested with both the ASP.NET Core demo and the jQuery demo. The .NET demo defaults to version 2024.2.514 and the jQuery defaults to the current version (2024.3.806), however I've tested with several different versions in the jQuery demo and they all yielded the same results.

Note: if you're unable to recreate any of the problems below, try refreshing the demo page and trying again. When additional data is loaded into the list via Ajax requests (ex. after scrolling through the list), this can interfere with the tests below. Refreshing will ensure there is no additional data from Ajax requests and only the data that was initially loaded into the list (the first 80 results).

Königlich

If you copy/paste the value "Königlich" into the textbox, the list of options is displayed with a matching option listed first (everything is working as expected so far):

If you hit backspace, however, the list of options is updated and the first option no longer matches (at all):

If you hit backspace again, the list of options is updated again, and now the matching value is back:

Backspace again, matching option disappears and the bad one is back:

It alternates like this each time you hit backspace, bouncing between a good matching value and a bad one that seems completely unrelated.

Queen

If you enter "Q", the list opens and the first option listed matches:

Add a "u" and the first option is no longer the match. However, the matching option is listed halfway down the list. Note that with Königlich above, this was not the case (notice in the screenshots above the first option has a border around it; there was no option in the middle of the list with a border).

Add "ee" ("Quee") and you're left with no more matches:

However, if you open the list and scroll down to 10372, you'll find there is in fact an option for "Queen" available that the previous entry wasn't finding:

Bon app

If you enter "B", the first option listed is a match. If you add an "o" ("Bo"), you're left with no matches:

But if you scroll down to 10331, there's an option for "Bon app" listed that wasn't matched above:

Blauer See Delikatessen

Same as above. Entering "Bl" finds a match, but "Bla" does not. Open the list and scroll down to 10501 to see the option that should have matched.

Summary

There seem to be several issues here:

1. Alternating between finding a matching value then finding a random value as each character is entered (most prevalent with Königlich).
2. Some options cannot be found via filtering (ex. all but the first above). Not only is it not running Ajax requests to find matches in options that haven't been loaded yet, but it also doesn't appear to find matches in options that have already been loaded via Ajax.
3. Matched option displayed in the wrong location (in most cases the match was displayed first in the list, but in one of the examples above it's in the middle of the list).

Bug report

When the user tries to set a repeat rule for an event, the spinners for the NumericTextBoxes are not displayed

Reproduction of the problem

1. Open the Demo - https://demos.telerik.com/kendo-ui/scheduler/basic-usage
2. Try to edit or create an event and click Repeat Daily

Current behavior

The spinners are not displayed. Also, the calendar icon is not displayed.

The following classes should be applied only to the parent element: k-recur-interval, k-recur-count, k-recur-until

Expected/desired behavior

The spinners and the calendar icon should be visible

The issue is a regression starting with 2023.1.117

Workaround

edit: function(e){

            $('[name="recurrenceRule"] .k-button-group-stretched button').click(function(){               
              $('.k-recur-interval.k-input-inner').removeClass('k-recur-interval')
              $('.k-recur-count.k-input-inner').removeClass('k-recur-count')
              $('.k-recur-until.k-input-inner').removeClass('k-recur-until')
            })

The issue is a regression starting with the 2024.2.514 version

Environment

• Kendo UI version: 2024.3.806
• Browser: [all ]

Reproduction steps: 

Try to expand a group in this dojo:

• https://dojo.telerik.com/aroxoYeB/5 

Workaround: 

Appending the following script right after loading the kendo scripts:

• https://dojo.telerik.com/aroxoYeB/6 

• kendo.ui.Grid.original_groupable = kendo.ui.Grid.prototype._groupable;
  kendo.ui.Grid.prototype._groupable = function() {
      let that = this;
      kendo.ui.Grid.original_groupable.call(that);
      if (!kendo.support.isRtl(that.element)) {
          return;
      }
  
      if (that._isLocked()) {
          that.lockedTable.on("click.kendoGrid", ".k-grouping-row " + "a[class*='-i-caret-alt-right']", that._groupableClickHandler);
      } else {
          that.table.on("click.kendoGrid", ".k-grouping-row " + "a[class*='-i-caret-alt-right']", that._groupableClickHandler);
      }
  }

Steps to reproduce the problem:

Have a grid with:

• specified width (e.g: 1000)
• column virtualization
• multiple columns with a width of 100, but most of them hidden in initial state (e.g.: 50 total, but only 8 shown)
• columnMenu true
• resizable true
  

When running the code that create the grid, the initial state looks like this:

Current behavior:

The header columns are filling the width of the grid (each bigger than the specified 100), but the rows columns cells have the specified width of 100, causing a misalignment.

However, changing the width of a column with the resize handle fixes all the widths (header + rows). 
Same thing for adding/removing a column from the menu.

See the attached video for an example.

If in the initial state there are more shown columns so they can fill the grid width (and have the horizontal scrollbar), the issue is not present.

Expected behavior:

Rows columns should always match the width of the header.

Dojo example:

Here's an example, based on the one from https://demos.telerik.com/kendo-ui/grid/column-virtualization 

https://dojo.telerik.com/@pgarand/UfEkIGiD

Bug report

copySelectionToClipboard() throws an error when the Grid has hidden column/s

Also if false is passed to the method  - grid.copySelectionToClipboard(false); - not all  GUID columns are copied to the clipboard

Reproduction of the problem
Dojo: https://dojo.telerik.com/OpiBoDaH

Bug report

When trying to import an Excel document into the Kendo UI Spreadsheet with a missing/corrupt image reference, the file will not show.

Reproduction of the problem

1. Import an XLSX file with a corrupted image into the Kendo UI Spreadsheet demo. (See ticket 1661911 for an example document)

Current behavior

The Kendo UI Spreadsheet fails to load the document.

Bug report

When the Add new Record button is clicked multiple times, the newly added row is not saved, when the 'Save' button is clicked.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/adURoNaH
2. Click the 'Add new record' button at least twice.
3. Try to edit the row and click the 'Save' button.

Current behavior

The row freezes and is not closed. If after clicking the 'Save' button the user clicks again the 'Add new record' the row is saved.

Expected/desired behavior

The row should be saved and closed when the 'Save' button is clicked, even if the 'Add new record' is clicked multiple times.

The issue is a regression starting with 2014.1.319 release

Environment

• Kendo UI version: 2024.2.514
• Browser: [all ]

As demonstrated here: https://dojo.telerik.com/oFiJOciY

I have the spreadsheet's first row and first column frozen.

I have also made the editor background red, so it is easier to visualize. 

Double click any cell below the frozen parts to enter editor mode, and you will see the editor drift out of its desired rectangle by 2 pixels,

 This is likely caused by the 2px border applied on the k-spreadsheet-pane

When the RowHeight of the Gantt is enabled and the planned tasks are shown, the height of the row in the timeline is miscalculated and that creates displacement. 

• https://dojo.telerik.com/EgiGiXUF/5 

Additionally, the task dots used for the dependencies are misplaced in the same scenario as demonstrated in the dojo above. 

Bug report
