• add 2 records => { id: 1, name: "null", id: 2, name: "Jack" }
• Name column for id = 1 is empty

I have tested this on your example for local data grid. It can be applicable also for remote grid, treelist, etc.

Bug Report

When creating the Grid from pre-defined HTML table, the header cells are missing classes. That results in inconsistency when using the Themebuilder to style the component.

Reproduction of the problem

1. Open this Dojo example, which contains a Themebuilder-generated stylesheet - https://dojo.telerik.com/wpmTrWPf/3

Current behaviour

The HTML for the first column is manually added to the predefined markup. The second column is left as it is. As a result, the second column is not being styled according to the stylesheet because it is missing HTML and classes

Expected behaviour

The Grid should render the column headers as if (or at least similar ) they are defined through the columns configuration.

Bug report

If the splitter container has 100%, the height of the Splitter panes is changed when the splitbar is moved to the right or left.

Reproduction of the problem

1. open the following example: http://dojo.telerik.com/EXOFEYon
2. move the splitter to right and left
3. height of panes is different depending on moving the Splitbar to the left or right

Current behavior

The panes of the splitter have the wrong height when it is moved to the left and the correct one when it is moved to the right.

Expected/desired behavior

Splitbar panes should have the same height regardless of splitbar moving.

Tip for fixing

When the splitbar is moved to the left, the left position of the second splitbar pane should be updated before its width. For now, it is updated after it, which causes showing a horizontal scrollbar of the Splitter parent for a moment. As result, the Splitter pane height is calculated wrongly.

Bug report

When trying to select a value from the modern Kendo UI TimePicker configured with Max and Min ranges, the currently selected value of the TimePicker is not updated.

Reproduction of the problem

1. Go to this Progress Kendo UI Dojo.
2. Open the TimePicker - notice it's at 9:00
3. Click Set
4. Value is set to 00:00.

Expected/desired behavior

Bug report

When clearing the contents of part of a Kendo UI DateRangePicker with a clear button, the change event does not trigger.

Reproduction of the problem

1. Go to this Progress Kendo UI Dojo.
2. Add dates to start and end inputs - Change event fires as shown in console.
3. Clear them with the clearbutton - Change event does not fire.

Expected/desired behavior

The Change event should fire when clear button is pressed.

Workaround

Subscribing to a mousedown event on the clear button, and manually triggering the change event. It will require a setTimeout due to timing purposes:

      //Mousedown event on clear button
      $("span.k-clear-value").on("mousedown", function(e){

        //set timeout for timing purposes
        setTimeout(function(){

          //reference DateRangerPicker and trigger Change event
          var dateRange = $("#daterangepicker").data("kendoDateRangePicker");
          dateRange.trigger("change");
        }, 200);
      });

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.
