To reproduce the issues, open this DOJO that just renders a grid in a dialog.

  1. open the dialog
  2. focus the "Add" button
  3. press TAB until the focus is on the first cell
  4. press ARROW DOWN (this focuses the checkbox in the cell below)
  5. press TAB

-> the close button of the dialog is focused

it doesnt't give the current dateTime in the MajorTimeHeader

I will include images for that

Bug report

Grid's Toolbar Columns Menu breaks after setOptions()

Reproduction of the problem

1. Go to and run this Dojo that combines the Toolbar Columns Menu demo and the Persist State demo: https://dojo.telerik.com/hVgwgCdr
2. Click "Save State" so you have some state data to restore later.
3. Click the Toolbar Columns Menu, uncheck "Contact Title", and click "Apply" to hide the column. The column gets hidden without a problem.
4. Click "Load State" to restore the previous state data. The column is displayed again and things are fine.
5. Click the Toolbar Columns Menu, uncheck "Company Name" and "Country", and click "Apply" to hide these columns.
6. Observe only one of these two columns was hidden and the Toolbar Columns Menu remains visible.
Open the Developer Tools, check the Console tab, and observe the error logged: "Uncaught TypeError: Cannot read properties of null (reading 'columns')"
It appears the columns menu's "this.owner" gets set to null at some point in the process of calling setOptions() and never gets set back to a reference of the grid.

Bug Report

When the Grid is exported with child columns hidden with Multi-column headers, the columns headers are not exported.

Reproducible

  1. Go to this Progress Kendo UI Dojo
  2. Export the Grid

Current Behavior

The column headers do not all export:
Image

Expected Behavior

The Grid should export all column headers like when they are not hidden - Dojo :
Image

Workaround

Explicitly set the parent column's exportable configuration to true - Dojo:

$("#grid").kendoGrid({
    columns: [
        { field: "name", title: "Name" },
        {
            title: "Address",
            exportable: true,  //set to true 
            columns: [
                { field: "street", title: "Street", hidden:true, exportable: true },
                { field: "city", title: "City", hidden:true, exportable: true }
            ]
        },
        { field: "phone", title: "Phone" }

In some scenarios, the PDFViewer does not show the correct end page in its toolbar.

I have a file with 73 pages; some of the pages have different sizes.

Current behavior: When I load the file in the PDFViewer and click the 'Last page' button, there is a slight moment where the correct page number is displayed (73), but after that it is changed to 71.

Expected behavior: The correct page number should be displayed when clicking the 'Last page' button.

This is an enhancement request.

Wizard buttons can be modified via the activate event and replaced with a fully initialized Button, but it would be better to just offer more of the Button properties right on the wizard steps.buttons object properties.  For example, the icon/image properties, fillMode, size, etc.

The timezone should be adjustable [e.g. like in Moment Timezone date.tz('Asia/Tokyo')] or today should be accessible/configurable from outside the widget. Currently getToday() always returns the local time. Suggestion: Add the attribute today to the options and change the initialization of var today = new DATE() in getToday() to var today = new DATE(options.today) ...

Hi!

I have noticed the following behavior of the Kendo-UI MultiSelect widget (reproducible in this DOJO):

  1. focus the button
  2. click on the X button of the selected tag in the MultiSelect to remove it

-> the button is still focused

The user has interacted with the MultiSelect, so it should grab the focus. Since the tag is removed, I would have expected the whole widget to be focused instead. At least this is what happens when clicking the "clear" button.
