Bug report

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

Environment

* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all] 

Dear Concerned,

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

2. Import attached Book21.xlsx file

3. I have first row as frozen pane and columns C, D are hidden

4. Select columns B to E using mouse drag & then right click on selected column , it does not show Unhide option, because on right click it keeps the selection only on column E

It does not work if we keep Freeze Panes.

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.

Reproduction of the problem

1. Open dojo at https://dojo.telerik.com/@GaloisGirl/AqotEtep
2. Click "Add expression" and pick "Product name",  "Is not equal to", "".
   
3. Click "Apply". The grid show 77 items, as expected.
4. Click "Add group" and then "Apply".
   

Current behavior

The grid shows 0 items. The expression preview is (Product Name Is not equal to '').

Expected/desired behavior

The grid should show 77 items. For an optimal user experience, the empty groups should be deleted when applying the filter.

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.

Environment

* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all] 

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.

Bug report

Reproduction of the problem

Scenario 1 Cascade with no pre-selected values.
Dojo example: https://dojo.telerik.com/uguXisaY/4

1. Select category “Baverages”, product “Chai” and order “Cunewalde”
2. Change category to "Condiments"

Result:
In R1 2019 the change event fires in disorder (Orders, Categories and Products)
In R3 2019 the change event fires for Categories and Products
In R3 2019 SP1 the change event fires only for Categories

Scenario 2 Cascade with pre-selected values
Dojo example: https://dojo.telerik.com/uguXisaY/10

1. Select category “Condiments”

Result:
In R1 2019 the change event fires for all ComboBoxes but twice for Orders
In R3 2019 the change event fires for all ComboBoxes
In R3 2019 SP1 the change event fires for all ComboBoxes but twice for Products

Scenario 3 Cascade in Grid with no pre-selected items
Dojo example: https://dojo.telerik.com/OpOkataY/9

1. Click Edit and select "BMW" in Brand.

Result:
In R1 2019 the change event fires for all ComboBoxes in inverse order: Year, Model, Brand
In R3 2019 the change event fires only Model and Brand in this order.
In R3 2019 SP1 the change event fires only Model and Brand in this order.

Scenario 4 Cascade in Grid with pre-selected items
Dojo example: https://dojo.telerik.com/OpOkataY/10

1. Click Edit and select "BMW" in Brand.

Result:
In R1 2019 the change event fires for all ComboBoxes in inverse order: Year, Model, Brand, but fires twice for Year
In R3 2019 the change event fires for all ComboBoxes in inverse order: Year, Model, Brand
In R3 2019 SP1 the change event for all ComboBoxes in inverse order: Year, Model, Brand, but fires twice for Year

Hi All,

Datepicker is closing after clicking month or year not waiting until selecting the date.

We are using IPAD IOS 13.2.2 version and loading the data in desktop website in IPAD. Dojo also not working properly in IPAD with desktop mode.

Thanks,

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

hello,

we recently upgraded the kendo from 2018 r1 to latest release. looks like there is a bug in the scheduler. With the server filtering and server operation true, I am unable to add Event(before upgrade it's fine).

check the dojo https://dojo.telerik.com/EhaXemiz 

can you please look into it.

Thanks,

Narendra

• Create a Toolbar with 2 SplitButtons in the Overflow
• Use Keyboard to open the Overflow Menu
• Keyboard Navigation is trapped in the first SplitButton and the second SplitButton can not accessed via Keyboard Navigation

See the following dojo: https://dojo.telerik.com/UtoTOcUD

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.

Hello,

We just upgraded our devices to iOS 13 and now sortable component it's not working properly on Safari.

We aren't able to drag the elements properly. We're running v2017.3.1026. Im not sure if upgrading to newer version will solve this problem.

Looking forward for your response.

Thank you!

Regards.

Bug report

Widgets that can be disabled through data attribute use the "data-enabled" attribute. The Button and the ButtonGroup use "data-enable" attribute.

Reproduction of the problem

Dojo example.

Current behavior

The Button and the ButtonGroup do not use the "data-enabled" attribute.

Expected/desired behavior

To avoid introducing a breaking change, the Button and the ButtonGroup should be able to use both "data-enable" and "data-enabled" attributes.

Dear Telerik team,

when I apply a HTML-text with a paragraph to kendo editor it does show a vertical scroll bar in IE. Which is wrong. Chrome does not. See this dojo: https://dojo.telerik.com/AsuNiPuh/4

How can I fix this?

Kind regards
