Hi,

the adaptive rendering in the grid control is not working in the current version(2019.3.1023).

To reproduce go to https://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance/adaptive#configuring-panes-on-mobile --> Open in Dojo --> Run and the 2 rows are not displaying. If you switch to version, choose Library dropdown, 2018.3.1017 or up to 2019.1.220 the 2 rows are ok. 

Similar behaviour is inspected to the scheduler control agenda view. To reproduce go to https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/adaptive-rendering#configuring-panes-on-mobile --> Open in Dojo --> Run --> change view from week to Agenda and the 2 events are not shown. If you switch to version, choose Library dropdown, 2018.3.1017 or up to 2019.1.220 the 2 events are ok. 

Tried in chrome, safari and mobile phones.

thanks,

Kostas Vlachakis

Bug report

Reproduction of the problem

Dojo example.

1. Drag the page splitter to resize the screen and see the Grid's pager correctly switch between the different responsive styles (expected)
2. Click the "Open Modal" button, which opens a Kendo Window with another Grid in it
3. Drag the page splitter and/or resizing the Window to see each of the Grid's paging styles changing accordingly (expected)
4. Close the Window (destroy is called in the deactivate event handler)
5. Try again to drag the page splitter to resize the screen. This time, the Grid's pager is no longer responsive

Current behavior

Responsiveness of the pager of a Grid declared outside the Window is affected by the Window's destroy method.

Expected/desired behavior

Calling the destroy method has no unexpected effect on components that are not nested in the Window.

Hi All,

We are facing a weird issue in kendo grid when both group paging and virtual scrolling are enabled for local data. Please see https://dojo.telerik.com/ICoDAleN/2 as example.

Steps to reproduce:

1. Run the code from https://dojo.telerik.com/ICoDAleN/2.

2. Try to group "DateTime" column by drag and drop to grouping header

3. After "DateTime" column is grouped, then un-group it by click cross icon of DateTime button.

4. Now you try to scroll down the grid, until ID column reach around 40, you will see the ID will jump back to around 0, and you will never see the rows which IDs are greater than 40.

5. If you open Developer Tools of browser, you will see following errors.

6. If you group other columns, for example, group "Subject" column, and then un-group it, then scroll down the grid, you will not see this issue.

How to fix it? is there any workaround?

Thanks,

David

The problem can be observed in the following Dojo:

https://dojo.telerik.com/UHAdoNIL 

The filter row appears on top of the Sticky Column.

Bug report

Pdf export comes with loader when Kendo grid with endless scroll and allPages enabled

Reproduction of the problem

https://dojo.telerik.com/ABiMAjIK

Expected/desired behavior
No loading indicator shall be rendered in the exported PDF

Environment
Kendo UI version: all
Browser: all

When the autofitcolumn method is used together with multi-headers and hidden columns, some of the columns are either not visible at all or shrunken.

The problem can be observed in the following Dojo:

https://dojo.telerik.com/EJezUyeg 

The CompanyName column should be visible, however it is not. If the example is ran in fullscreen, the column will be visible, however it will shrink if the Browser window gets smaller.

### Bug report

The Grid is filtered initially and no records are displayed. When a specified filter is cleared through the column filter menu, the column with the checkbox filter menu does not show any checkboxes and there is an error in the browser console.

### Reproduction of the problem

1. Create an initially filtered grid and enable the checkbox-filter menu on the first column.

2. When the grid is loaded and no records are displayed (based on the applied filters), clear any of the filters manually through the column menu.

3. Click on the column menu of the first column.

4. An error is logged in the browser console. The checkbox-filter menu contains no options, but the column has data.

A Dojo sample for reproduction: https://dojo.telerik.com/oJAvaMUy

### Expected/desired behavior

The options in the checkbox filter menu should be loaded properly when any column filters are reset.

Bug report

In the Html4 specification it required the tbody element to follow the tfoot element. In contrast, the current Html5 specification favors the thead > tbody > tfoot structure, even though it doesn't explicitly forbid the table's tfoot element to be rendered after the thead and before the tbody element: https://html.spec.whatwg.org/#the-table-element
In terms of accessibility, it makes more sense the tfoot element to be rendered after tbody. This way the readers would be able to read the elements in a logical order: thead > tbody > tfoot

Reproduction of the problem

https://demos.telerik.com/kendo-ui/grid/aggregates

Inspect the footer

Current behavior

tbody is rendered after tfoot.

Expected/desired behavior

tbody is rendered before tfoot.
