Kendo UI version: 2020.3.1021
jQuery version: x.y
Browser: [Chrome | Firefox ]

I'm seeing an error in the Chrome console when the filter menu is clicked on in a kendo grid: https://demos.telerik.com/kendo-ui/grid/filter-menu-customization

You can see the example in the link above by opening your console in Chrome and clicking on the filter button. 

Here is the error:

Blocked aria-hidden on a <a> element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.

Reproduction:

1. Run sample at https://dojo.telerik.com/@GaloisGirl/iGArIqup/3
2. Try to heighten item A or C

Actual result: only item B can be heightened

Expected result: all items can be heightened

Current behavior

Bug report

The DropDownList does not change its popup height when items added/removed from its source.

This is a regression introduced with 2023.1.314 release.

Reproduction of the problem

• Run the following Dojo: https://dojo.telerik.com/aCoHAZuK/4
• Add new item to the list
• Open the popup again - a vertical scroll will be present, while the popup should be resized to display all the three items

Expected/desired behavior

The popup height should change according to the new number of items.

Environment

• Kendo UI version: 2023.1.425
• Browser: [all]

Dear Concerned,

 

1. Launch https://demos.telerik.com/kendo-ui/spreadsheet/index

2. Try to select columns B to D using mouse

3. Click on column B, keeping mouse clicked, move your mouse towards C then D

4. It does not allow to select B,C,D where as it is possible in Excel.

It is serious issue for me as I could not proceed with Hide/Unhide columns and some other features depend on multiple columns selection

Note: if we add a blank row at first position then it works well, seems like first with merged columns is creating problem.

Dear Concerned,

1. Launch https://demos.telerik.com/kendo-ui/spreadsheet/index

2. Open Workbook(1).xlsx (attached)

3. Edit B2, D2, F2 with some new values

4. See the results in B4, D4, F4

Calculations are different in Excel.

 

I'm observing this issue with the Demo version of the DateRangePicker: https://demos.telerik.com/kendo-ui/daterangepicker/index

 

1. Enter Start Date via keyboard (ex. 7/1/2017)
2. Click on End Date to select a date in the popup calendar (ex. 7/10/2019)

 

The End Date is not set and the Start Date changes to the selected End Date.

1. Open https://dojo.telerik.com/IjasAbeC/3

2. Background color and text color buttons are initialized as a group. These buttons are not working if we put them in a group

3. If we keep them separate, outside group, the buttons work as expected.

Dear Concerned,

1. Open https://dojo.telerik.com/IjasAbeC/11

2. Check split button is not prefixed with a separator, where as all other buttons comes with prefixed separator

It seems a bug, please provide a fix.

### Bug report
The Ctrl + Shift + Arrow key keyboard shortcut should select a range in the row/column starting with the active cell and ending with the first cell in the row/column that has a value: [list of shortcuts](https://docs.telerik.com/kendo-ui/controls/data-management/spreadsheet/end-user/list-of-shortcuts) used by the Spreadsheet. It works similarly in Excel. 


### Current behavior
The selection does not end at the first cell that has a value, it ends with the last cell of the row/column.  

### Expected/desired behavior
The expected behavior should be as described in the documentation: "Extends the selection of cells to the last nonblank cell in the same row or column as the active cell."

We have a project where we need the infinite scroll, column sorting/filtering, and remote data enabled.  We are having some issues with sort and filter.  For quick reference, I used the grid demo and changed it to reflect our configuration.  The problem is the grid fires the read command twice when we have loaded more than one page of data. No issues when we have only loaded the first page.

https://dojo.telerik.com/UDoREFID

To reproduce:

1.  Open Chrome

2.  Load the page

3. Hit run

4. Open Developer Tool

5. Switch to the Network tab and filter by XHR only  

7. Click ProductName to sort. There is only one AJAX call.

8. Scroll to the bottom so it loads the next page. It made two AJAX calls

To reproduce
Steps to reproduce the behavior:

step1: Make a cell become wrap text and text something

 

step2: Export to pdf file:

 

Expected behavior
Text display same as on safari

Please fix this problem asap!!!.
