Bug report
Reproduction of the problem
When the Editor is rendered in a long page with a scroller and the user paste a content replacing the entire content, the entire page scrolls, not only the Editor content.
- Open the Dojo - https://dojo.telerik.com/wKDfkpEW
- Copy long content for example from above the Editor
- Mark the entire content in the Editor and paste the previously copied content
Current behavior
The entire page scrolls and in some cases the Editor is not visible.
screencast - https://go.screenpal.com/watch/cOQTlxnxqVk
Expected/desired behavior
Pasting in the Editor should not affect the page scroller.

- Hover over a diagram shape for the tooltip to appear.
- Double click to destroy the Diagram.
Current behavior
The Tooltip will remain after the Diagram is destroyed.
Expected/desired behavior
The associated Tooltip should be destroyed with the Diagram.
Environment

The details for this can be found in ticket #1519224
Given some XML that has child nodes and attributes, I'm binding to a grid with no problem. The child grid for each row (built using detailInit) get's the data from the parent row e.data.get("BillRows")
If those rows have attributes, the '@' signs breaks the javascript for the grid. As you can see in the ticket, every attribute needs to be renamed before I can build the child grid.
Should be a way to use attributes in XML bound to a datasource/grid for all levels of grids.

When trying to move an event vertically inside the scheduler, the entire web page is scrolling. This cause the event to not move has supposed to.
The problem can be exprienced on the demo page of the scheduler : https://demos.telerik.com/kendo-ui/scheduler/move-resize
Thank you
When a kendoContextMenu is applied to a combobox (html tag select) you are not able to show the select options by tapping it. The behaviour is on mobile browser only (tested iPad and Google Chrome developer tools with device toolbar enabled).
I reproduced the issue in telerik dojo, here is the code.

Hi,
I've notice an issue with Scheduler: the height for group slot is not correct calculated and items goes down to the next group slot.
Scheduler :
- group vertical after a field
- type of scheduler: "timelineWeek" or "timelineMonth"
- items of the group have same start date and their number are bigger then 20.
kendo ui version: 2020.1.219. Same issue with 2021.1.119
----------------------------------------------------------------------------------------------------------------------
I've created a dojo as example: https://dojo.telerik.com/EHeNigIQ . Also, you can see the issue into the picture bellow.
You can modify the variable "rows = 30;" and you will see more items that goes wrong into the other group slot.
I have upgraded a huge project we have, from Kendo UI 2017 to the latest version.
I managed to fix all the incompatibility issues that I had with the latest version and now it's ready to go live.
In the final regression tests our customer found a bug and now we are stack and cannot deploy the project.
Here is the problem:
In the DropdownList, if you type something and then press the clear button, the change event is firing two times. One with the value that you typed before and then one again with an empty value (the right one). The biggest problem is that there is no way to determine that the first event is coming from the clear button and not from the user, so I cannot find any workaround this.
I searched and I found that this started after this change.
You can check this dojo for a reproduction of the problem.
Steps:
Type "it" in the dropdownlist,
Wait for the items to popup
Don't select any item but press the clear button of the dropdownlist
You can see the attached image the wrong events.
If you select a version after 2019 R3, the change event is firing twice. If you select an older version the change event is not firing at all.
I can understand a change event with an empty value and I don't have any problem with that, but the first event is totally wrong.
Is there any quick solution to this so we can catch the deadline and deploy the new version of our project?
Thank you for your time,
John Dendrinos
As of version "@types/kendo-ui": "2020.3.0":
FileManager methods: path, view, getSelected, getSize have return type void, which is a pain to handle since it can't even be cast to bool.
FileManager method navigate doesn't accept params, should accept string 'path'.
FileManager method executeCommand doesn't accept params, should accept as per https://docs.telerik.com/kendo-ui/api/javascript/ui/filemanager/methods/executecommand .
FileManagerContextMenu interface is missing all event handlers: close, open, activate, deactivate, select.
The following are not exposed:
- kendo.data.schemas
- kendo.ui.filemanager.commands
Follow steps in sample at https://dojo.telerik.com/@GaloisGirl/OJUPoYOY/8
- Actual result: the call to "create" has no information that the new folder should be created in "folder 1"
- Expected result: the call to "create" should contain information about the path, for my back-end to create an entry in the correct place
Probably related to https://feedback.telerik.com/kendo-jquery-ui/1473893-filemanager-no-path-passed-to-datasource-read-method / https://github.com/telerik/kendo-ui-core/issues/5890
Please investigate this dojo sample:
https://dojo.telerik.com/IjIminuv
Even looking at the built-in Timeline view, one can see that the bottom gap is thinner in every group. However, switching to the TimelineEx view (that sets BottomRowOffset to 0), the problem is obvious...
Please address this computation error in the row-height...
Regards
Bug report
When a user mouseover's a specific element that produces the Kendo UI Tooltip initially with a position of bottom, the tooltip is below the browser window. Upon the mouseover a second time, the tooltip shows changes position to top.
Reproduction of the problem
- Go to https://dojo.telerik.com/@PMcDonou/uzOyoROh
- Mouseover the clip icon at the bottom of the Grid.
Current behavior
This will initially appear below the window. Upon mouseover a second time, will be above. Here is a screencast of the behavior.
Expected/desired behavior
The Kendo UI Tooltip should appear above to initially instead of being displayed outside the user's view.
Environment
- Kendo UI version: 2020.3.915
- Browser: all
The grid dataBinding event exposes useful information like the action, based on which I can implement my logic.
The treeList equivalent only has the sender, making it virtually useless.
When trying to navigate the toolbar of the editor with a keyboard, the focus is stuck/not working for color pickers.
When using Tab(or RightArrow) from the left the focus is stuck on the first colorpicker.
When using Shift+Tab(or LeftArrow) from the right the focus is stuck on the last tool before the colorpicker.
See DOJO: https://dojo.telerik.com/aKOKOwiP
Disclaimer: I'm running an older version of Kendo UI for jQuery, so this may have been fixed. I'd like confirmation if so before updating.
Kendo version: 2017.1.118.545
I am creating a grid from a table data source rather than an endpoint call. Other pages that use endpoints to populate the datasource export Excel with no problems.
Example HTML:
<table class="table table-responsive" id="tblReportSummary">
<colgroup>
<col />
<col />
<col />
<col />
<col />
</colgroup>
<thead>
<tr>
<th data-field="date">Date</th>
<th data-field="totalForStatus">Count</th>
</tr>
</thead>
<tbody>
@foreach (var item in ViewBag.ReportDataSummary as IEnumerable<UtilizationListViewModel>)
{
<tr>
<td>@item.Date</td>
<td>@item.TotalForStatus</td>
</tr>
}
</tbody>
</table>
The jQuery is as follows:
$("#tblReportSummary").kendoGrid({
sortable: true,
toolbar: ["excel"],
excel: {
allPages: true,
fileName: "Utilization Data Export.xlsx"
},
pageable: {
pageSize: 20,
pageSizes: [20, 50, 100]
}
});
When I click Export, all I get is an empty Excel file.
Why isn't the data there, please?
The documentation at https://docs.telerik.com/kendo-ui/api/javascript/ui/toolbar/configuration/items.menubuttons does not mention the children of a splitButton can have their own click handlers. It's not present in the typings either.
However, this does work: https://dojo.telerik.com/@GaloisGirl/UYeBewEX
Somewhat related is this bug: https://github.com/telerik/kendo-ui-core/issues/4542 . Documenting the behavior would be useful in accurately describing this bug.

Dear Concerned,
1. Open https://demos.telerik.com/kendo-ui/spreadsheet/index
2. Select column B and drag mouse towards C, both columns will be selected which is correct behavior
3. Now just scroll down 2-3 rows using vertical scroll bar
4. Repeat step 2, this time it does not select B & C, instead it selects B,C,D,E.
5. Seems a bug, not an expected behavior.
Observation that might help you in fixing it:
1. if you move scroll bar in such a way so that no merged cell is visible it works well, e.g. scroll down till 20th row becomes first visible row on screen and now repeat step 2, it will work
2. if scroll position is on top then behavior is correct as well
3. Same issue exists in case of multiple row selection with merged column and scroll position.
On https://demos.telerik.com/kendo-ui?_ga=2.149841974.1082962146.1579102350-1080570292.1579102350 , all links in the "Sample Applications" section return 404 (for example https://demos.telerik.com/bootstrap/ )
Removing all URL params helps.
Any URL param ( https://demos.telerik.com/kendo-ui?x=1 ) reproduces the issue.
