If you configure a Kendo Grid with client-side paging, each time you call setDataSource to update the data source then a new .k-pager-numbers-wrap DIV is added to the page controls. I've replicated the problem in Dojo at https://dojo.telerik.com/UTolOzer by taking a basic client-side paging demo, moving the dataSource configuration into a separate function (with data("kendoGrid").setDataSource), and calling that function 25 times. At the end, the source shows the UL element with the page buttons inside 25 .k-pager-numbers-wrap DIV elements.

I first noticed this problem because in my own environment, each nested DIV was shifting the page buttons left 1 pixel and overlapping the "previous page" buttons. In my Dojo example, with 25 nested DIVs the page buttons disappear completely.

I've added the following in my own code as a workaround in the dataBound event of the grid:

                            var trueParent = e.sender.pager.element.find(".k-pager-numbers-wrap").first();
                            e.sender.pager.element.find("ul").appendTo(trueParent);
                            trueParent.find(".k-pager-numbers-wrap").remove();

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

The expandTo and expandPath methods of the TreeView do not change the data-expanded and aria-expanded attributes to "true".

Reproduction of the problem

  1. Open this Dojo, which demonstrates two different TreeViews using the two methods.
  2. Inspect the expanded items.

Current behavior

After the items are expanded, their data-expanded and the aria-expanded attributes are false.

Expected/desired behavior

After the items are expanded, their data-expanded and the aria-expanded attributes should be set to true.

The workbook exporting to Excel generates a corrupted file when the name of some of its sheets contains a "cell-related" value - for example, "A1", "G5", "F45", etc.

Reproduction of the problem

  1. Open this Dojo project and run it
  2. Save the exported Excel file and open it.

Current behavior

When the saved file is opened in Excel, a "corrupted file" warning appears on the screen.

Expected/desired behavior

There shouldn't be any warnings when opening a saved workbook

Since you guys don't seem to have a dedicated place to report bugs in your software.....


Attempting to use the DateTimePicker without supplying something before the Hour in a 24 hour time picker option doesn't work. 


$('selector').kendoDateTimePicker({
    format: 'H:mm'
});


This fails completely, and instead renders it as if it were 12 hour based. However, putting a single space before this renders properly:

$('selector').kendoDateTimePicker({
    format: ' H:mm'
});

However, this also includes the space, which is undesirable.

This does not appear to occur when it is included with a date in any fashion.

When the data source of the Kendo UI ScrollView is configured to accept a function, two requests are sent. 

Reproduction of the problem

1. Set the read of the data source to function.

2. Set server paging to false (by default is false).

Dojo for reference:

https://dojo.telerik.com/ePIpejar

* **Browser:** [all]

In the DropDownList and ComboBox, virtualization only works when the popup is open. In both widgets, item navigation is functional by pressing down to select the next item in the list without opening the popup. However, when the end of the first page of results is reached, the selection goes back to the top of the first page of results instead of loading the second page via virtualization. This misleads the user in that it only presents a portion of the options available. This is also an issue for disabled users and accessibility.

https://demos.telerik.com/kendo-ui/dropdownlist/virtualization

https://demos.telerik.com/kendo-ui/combobox/virtualization

In both examples, holding down without opening the popup will never load more results.

We have had this issue in the past but it is a bigger issue now that we are focusing more on accessibility since users rely more heavily on keyboard navigation.

Hi,

 

I encountered a bug when using the spreadsheet control with a remote datasource which I was able to replicate using the datasource binding demo (https://demos.telerik.com/kendo-ui/spreadsheet/datasource).

When entering data on an empty cell in an empty row not adjacent to a non-empty row (e.g. a row that is two rows below the end of the data); then editing a cell in the same row, but adjacent column, this creates two items in the corresponding datasource.

Editing an empty row above this new row will modify one of the records created in this process.

Bug report

When the horizontal scroll of the grid is shown and is configured for RTL, the resize handle is mispositioned. 

Reproduction of the problem

1. Make the grid scrollable and set explicit widths to all columns.

2. Make the grid RTL.

3. Introduce multi-column headers.

4. Notice that the columns cannot be resized due to the disposition of the handler.

5. Dojo for replication:

https://dojo.telerik.com/IZInOVUd

6. Notice that whenever the horizontal scroll is not present, the resize handle is positioned correctly.

I tested the toolbar example https://demos.telerik.com/kendo-ui/toolbar/keyboard-navigation with a keyboard and screen reader (NVDA) and found the following issues:

1. Buttons are rendered as links. The SR announces the first button as "Button visited link". Apparently, there is an undocumented option useButtonTag (https://github.com/telerik/kendo-ui-core/issues/4730) that's also missing from the typings. I have to manually add 'role: "button"' to every single button to make my toolbar compliant.

2. Toggle buttons state is not announced.
 
3. The overflow menu button has no caption and is announced by the SR as "blank".

4. The overflow menu button has no visible focus styling (screenshot attached).

5. Selecting an item from the overflow menu throws the focus out of the page.

Sometimes, I need to present a dynamic list bound to a dataSource. I believe ListView is the widget for that.

However, ListView adds role="listbox" to the root element and role="option" to children.

Per https://www.w3.org/TR/wai-aria-1.1/#listbox , a listbox is a widget that allows to select an item. A non-selectable ListView should have role="list" and its children should have role="listitem".

I prepared a dojo example. https://dojo.telerik.com/oKIkuCaP

As can be seen from example, the MVVM context menu seems to ignore data-copy-anchor-styles option.

Current solution for us is to extend the kendo.ui.ContextMenu and set the copyAnchorStyles option to false.

As per https://docs.telerik.com/kendo-ui/api/javascript/ui/combobox/events/select I am expecting that select does not fire when the user enters text but does not select an item from the list. This is consistent with your other widgets like AutoComplete.

 

However as seen in this dojo https://dojo.telerik.com/ESOJibEB select triggers whenever I enter text and click off the box instead of only when I click an item in the combobox.

 

How to reproduce:

  • Open above Dojo
  • Click in the combobox and type some text.
  • Do not click on an item in the list and instead just click anywhere else on the page.
  • Check console and you will see select has been printed.

 

If you need any other help, let me know.

 

Kind Regards,

Ben

 

PS Im forced to select a browser but this is the same across both chrome and firefox.

Dear Telerik team,

Dear Concerned,

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

2. Copy from F3:F15

3. Paste as value (ctrl+shift+v) in H3

4. See it pasted only non-empty cells

Empty cells values should be pasted as well as Excel does.
