When I select time slot and then I will go to scheduler calendar, everything is ok. But then when I select one day earlier and open scheduler calendar it's showing previous date. It's reproduceable in latest version https://demos.telerik.com/kendo-ui/scheduler/index (https://dojo.telerik.com/EcalidON) with an option (selectable: true)

Green circle shows it works correctly.

Red circle shows it doesn't work correctly.

I observed it happens when I click one day before previous selection.

Hi Support,
I have some issues with the copySelectionToClipboard Method for the Grid widget

In the first one, the copy function of the table seems to have a problem with locked columns. In the dojo of the first problem the table headers are displayed shifted.

Secondly, grouped table headers are not copied. To see in the second dojo.

Lastly, it should be mentioned that the definition for the copy method is not included in the kendo-ui npm packet

Problem 1:
https://dojo.telerik.com/OBOQemUm

Copy result in Excel:

Problem 2:
https://dojo.telerik.com/OBOQemUm/2

Copy result in Excel:

 

Best regards,

The interface for PromptOptions does not extend DialogOptions like it should. I added it into my definition file, and it compiles and works fine when testing.

    interface PromptOptions extends DialogOptions {
        name?: string;
        messages?: PromptMessages;

In a very special case it is impossible to select a value from the ComboBox. It only occurs on iPads.

if ComboBox filter is set, virtualization is on and the datasource is set programmatically after initialization. A data item cannot be selected from the list if it is filtered before hand and the item is located at the second page inside the popup.

Steps to reproduce:

  1. Open https://dojo.telerik.com/UbuRecut/4 on an iPad
  2. Wait till data source is set
  3. Input filter value (Popup should open and be scrollable)
  4. scroll to the end of the popup
  5. click element at the end of the list
  6. No item is selected

In a grid with virtualization, when just normally scrolling down requests for the exact same data are often sent multiple times after each other. The reason for this is probably that the grid sends an asynchronous request for example Top 100, Skip 200 and then does not keep track of that it is still waiting for a reply for this request, before asking for the same data a short period later. 

Commonly requests for the same data is made 2 or 3 or more times after each other, causing performance problem at the server side and in many cases unnecessary calls to the database. Fixing this should lower the number of requests for data to the server considerably, maybe with a factor two or more with just normal grid operation when the user is just scrolling down to view more data in the grid.  

To demonstrate the problem, open a copy of the virtualization grid demo, for example here:

https://dojo.telerik.com/iXijoyaY

Open the Developer Tools and just observe which network requests are sent to the server. Just scroll down in any way and observe that very often the exact same request is made. A request for the same data has the same Top and Skip values in the parameters sent the server. You can see the servers reply is exactly the same JSON data multiple times after each other.

Solving this performance problem almost completely would seemingly be to in a variable just keep track of the "Latest request" sent, since the problem happens mostly just with normal scrolling in one direction with request sent after each other. So one would need to keep track of that a call for Top 100, Skip 200 has been made, and if the program wants to request the exact same data again, just wait for a reply for the first request, instead of sending a new one. (If needed, send a new request only after a specific timeout for a reply for the first one).

A more thorough solution would be to have a data structure to keep track of the Top and Skip tuples for all the calls to the server that has not yet have had a reply from the server, and not repeat those exact same calls again if still waiting for a reply for the first request.

Bug report

When the filtering mode of the grid is set to "row" and the filter is programmatically cleared, the "Clear filter" button does not hide.

Reproduction of the problem

Set filterable: {mode: "row"}.
Filter for instance "Is null" or "Is not null".
Clear the filter - $("#grid").getKendoGrid().dataSource.filter({});
The "Clear filter" button is not hidden
sample Dojo:

https://dojo.telerik.com/AVOqifeK

If there is text in the filter's input, the button is hidden.

Expected/desired behavior

Hide the "Clear filter" button, irrespectively whether the filter has been cleared programmatically or via the UI.

Reproduction steps:

1. Open column menu

2. Using arrow keys, go to Filter menu item.

3. Hit right arrow to open Filter submenu

4. Tab through filter submenu

5. Hit escape.

Expected behaviour: Filter submenu closes and focus returns to the parent column menu

Actual behaviour: Both filter and column menu are closed.

Snippet: http://dojo.telerik.com/@gearoidj/iqiwUCEp

 

This is an issue for accessibility users - there doesn't seem to be a way to return to the parent filter menu using the keyboard without closing all menus and reopening them.

There is one way for it to occur, and that is to use the mouse to place the focus on the Filter menu background - in this case hitting escape will close the Filter menu and focus will be returned to the parent column menu. However this is impractical for an accessibility user who is relying solely on keyboard navigation.

 

An example of where this (mostly) works is on the Columns submenu - the user can use the left arrow key or Escape to close the child menu or alternatively keep tabbing and they will eventually return to the parent menu (though if they do tab within the child menu, hitting Escape will close both the child and parent menus).

Bug report

When there is a DOM element with "page-break" class inside an element that is about to be exported to PDF, this "page-break" results in a new page in the reported PDF file.

If we hide the parent element in which the element with a "page-break" class is nested and export the content to PDF, in the result file, the content of the hidden DIV is not displayed but there are blank pages for each "page-break" class that can be found in the hidden element.

Reproduction of the problem

  1. Open this Dojo and run it
  2. Press the "Hide the DIV element in red" button
  3. Press the "Export to PDF button" and open the exported file

Current behavior

There are two blank pages at the beginning of the exported document. Each of these pages is a result of the "page-break" CSS classes inside the "#test" element

Expected/desired behavior

The "page-break" class should not result in the exported file if it is nested in a hidden element. Here is a Dojo demonstrating the correct behavior: https://dojo.telerik.com/iZAXiZEz

Bug report

The DropDownTree allows us to configure its checkChildren and filter options. Both options are working correctly, when used separately.

When the two options are defined for the DropDownTree, the checkChildren options don't select the child elements of a given node that is checked.

Reproduction of the problem

  1. Open this Dojo example
  2. Expand the DropDownTree popup
  3. Check the "Furniture" node checkbox

Current behavior

Only the "Furniture" checkbox is being checked

Expected/desired behavior

The "Furniture" and all of its child nodes should be selected when clicking on the "Furniture" checkbox.
Here is a Dojo example in which the checkChildren configuration is working as expected.

The text inside the TreeMap's leaves have their colors incorrectly inverted in dark mode despite the background colors remaining the same. This is especially prominent on background colors such as yellow where the now white text can completely blend into it. This problem appears to apply to all dark themes; I've attached a screenshot of the demo in default dark as an example.

This is only i minor issue, since the actual method seems to be working fine. I just thought i would bring to you attention that the demo page for the JQery method getOptions is havinf issues.

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/methods/getoptions

Steps to reproduce:

  1. Navigate to the link
  2. click on the preview tab of the example

Below are some of the more noteworthy errors and warnings:

The following issue is only present in a Firefox browser:
Changing the value of a TimePicker input field through code can sometimes cause the entire browser to scroll to the top of the page.

Was tested in:
Firefox 114.0 (64bit) 
(User Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/114.0")

Reproduction: 

  1. Create an input and initialize it as a TimePicker. 
  2. Open the TimeView dropdown element either by clicking the button next to the input field, or by code (timePicker.open())
  3. Close the TimeView dropdown element either by clicking the button next to the input field again, or clicking away from it anywhere on the page, or by code (timePicker.close())
  4. Scroll down any amount from the top of the page.
  5. Use the timePicker.value(...) function to set the value of the TimePicker field. The selected value has to be equal to any of the options available in the TimeView dropdown element.
  6. The browser will scroll to the top of the page.

Test in Dojo: https://dojo.telerik.com/UdoLAkat/4

Expected behaviour: 
- After step 5. the value should just update in the TimePicker input field without causing any scrolling to happen.

I am assuming this behaviour happens because the TimeView component is attempting to scroll within its <ul> element to the option that has been selected by the .value(...) call, but since the entire TimeView component and all of its elements are hidden, Firefox somehow misinterprets the scrolling and scrolls the main viewport to the top of the page instead.

When the browser is zoomed, the TabStrip scroll right arrow does not change to disabled when there are no more tabs to scroll into view. 

It looks like the problem is in kendo.tabstrip.js _toggleScrollButtons function, the following line:

that._scrollNextButton.toggleClass('k-disabled', scrollLeft === ul[0].scrollWidth - ul[0].offsetWidth);

When the browser is zoomed, kendo.scrollLeft(ul) returns a decimal value.  https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollLeft has the warning: "On systems using display scaling, scrollLeft may give you a decimal value."

scrollWidth and offsetWidth are rounded to integer.

My workaround is to override the _toggleScrollButtons function and do the following:

that._scrollNextButton.toggleClass('k-disabled', Math.abs(scrollLeft - (ul[0].scrollWidth - ul[0].offsetWidth)) <= 1);
