Bug report

The dataSource filter configuration only accepts string as value.

Reproduction of the problem

1. Open the Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/uVAgAYem
2. Open the MultiSelect.

Current behavior

An error is thrown and the MultiSelect does not open.

Expected/desired behavior

There should be no error and the MultiSelect should open.

Environment

• Kendo UI version: 2021.2.511
• Browser: [all]

The Typescript definitions for Kendo UI define the connections() method which is part of the kendo.dataviz.diagram.Shape interface as follows:

connections(type: string): void;

The documentation (https://docs.telerik.com/kendo-ui/api/javascript/dataviz/diagram/shape/methods/connections) however, specifies:

Returns the connections attached to the shape. You can optionally specify to return only the incoming or outgoing connections.

Therefore, connections() should not be of type void and the type parameter should be optional.

To solve this issue, we currently cast both the parameter and the result.

In Excel I can create a merged cell. For this example, I will merge A1:B1 and name the range MyCell.  Next I name the single cell D5, and call it MyAnswer.  I can enter the following formula into MyAnswer, =MyCell and Excel will return the result.

Using Telerik if I create the same layout I get a #Value or #Spill error because Telerik requires MyAnswer to be the same merge configuration as MyCell which creates a significant disadvantage in usability.

Can you please advise when this issue will be fixed in Telerik.

I have attached a screen recording of this not working in your Dojo named "Telerik merge cell reference not working when not same col.mov".

Thank you so much.

When there are merged cells and the SUM formula is used for the merged cells the result is wrong (it depends on the count of the merged cells)

Reproduction of the problem

1. Open the Dojo
2. Enter for example 5 in the merged cells (A1:B2)

Current behavior

The result in the D1 cell is 20. ( value of cell * count of cells in merged range)

Expected/desired behavior

The result should be 5. In the same scenario, the result in Excel will be 5.

Hello,

in the Typescript bindings, the JQuery $("...").data("kendoXXX") Methods do not include undefined in there return values.

https://docs.telerik.com/kendo-ui/intro/widget-basics/jquery-initialization#duplicate-initialization

-> in the second script section, it is also documented that it can return undefined, when there is no widget instance found.

It also returns undefined, when the selector doesn't match any element.

Please include undefined in the return values.

Bug report

When tasks are reordered in Gantt duplicated requests are sent for updating.

Reproduction of the problem

1. Open the Gantt Overview Demo
2. Reorder two tasks and inspect the requests in the Network tab

Current behavior

For example, in case two tasks on the same level are changing their places, four requests are sent, two by two the requests are the same.
In case a task is moved on a different level multiple requests are sent, as all are duplicated.

Expected/desired behavior

There should be no duplicated requests when reordering tasks in Gantt

This is a regression introduced with R3 2020 (2020.3.915)

Hi All,

We are facing a weird issue in kendo grid when both group paging and virtual scrolling are enabled for local data. Please see https://dojo.telerik.com/ICoDAleN/2 as example.

Steps to reproduce:

1. Run the code from https://dojo.telerik.com/ICoDAleN/2.

2. Try to group "DateTime" column by drag and drop to grouping header

3. After "DateTime" column is grouped, then un-group it by click cross icon of DateTime button.

4. Now you try to scroll down the grid, until ID column reach around 40, you will see the ID will jump back to around 0, and you will never see the rows which IDs are greater than 40.

5. If you open Developer Tools of browser, you will see following errors.

6. If you group other columns, for example, group "Subject" column, and then un-group it, then scroll down the grid, you will not see this issue.

How to fix it? is there any workaround?

Thanks,

David

Dear Support,

I have some forms that is bind to MVVM and I am binding the VM's change event to check for any pending changes on the form.  The issue I am having is for textarea that is bind to null value, if I tab/click on the textarea and leave without making any changes, it will still trigger the VM's change event.

What is the solution for this?

Hi,

We are using DatePicker and DateTimePicker with DateInput.

Since Kendo UI 2021 R1 the DatePicker is showing the DateInput mask when the value is null. The DateTimePicker behaves correctly.

I've prepared an example. The value is set to null manually here, but in our code it is set via MVVM binding. 

https://dojo.telerik.com/OcaVaWoX

Reproduce:

1. Select Version Kendo 2020 R3: The DatePicker and DateTimePicker are both empty. That's the expected behavior.

2. Select Version Kendo 2021 R1: The DatePicker now incorrectly shows the DateInput mask, the DateTimePicker shows the empty picker correctly.

Best regards

I am trying to upgrade to jQuery 3.5.1 and as per the documentation regarding compatible KendoUI versions I have upgraded KendoUI to v2021.1.119 (R1 2021). Now even though this version is compatible, I am getting warning messages from jQuery Migrate plugin as follows:

Wondering if this issue is known and support for the issue is on its way. Or else is it reccomended to change the minified JS files as these seems to be simple fixes.

Thanks!

In my application I am using the following. 

kendo.ns="kendo-";

Dojo example: https://dojo.telerik.com/@iankodj/aKIyEwUv 

The spreadsheet component works well with the namespace, however any dialogs that the component opens do not function correctly.

For example, I am using Edge browser. If I copy a cell and they try and past the value via the context menu, a dialog appears telling me to use the keyboard.

The "ok" button of the dialog does not work. Looking at the html source that is added to the DOM, it appears that the button is trying to bind to the click event via a "data-bind" attribute rather than a "data-kendo-bind" attribute as specified via the namespace.

The attached file show the behavior with the Basic demo example having the kendo namespace set.

Thanks,

Darin

The problem can be observed in the following Dojo:

https://dojo.telerik.com/UHAdoNIL 

The filter row appears on top of the Sticky Column.

Bug report

Reproduction of the problem

Dojo example: http://dojo.telerik.com/ePEPAtEl/3
Two scenarios:

1. The DropDownTree's height is set to "auto" and there are enough nodes in the embedded treeview, so that the when the popup shows up a vertical scrollbar appears. In Chrome and IE, when the scrollbar appears the page is scrolled down automatically, which causes the popup to close.

2. height is not set explicitly in the DropDownTree (remove the setting from the dojo example). If the browser window is resized so that there isn't enough space for the whole popup to be displayed, on the popup showing up, the same behavior as in 1. is observed.

Current behavior

The popup closes automatically.

Expected/desired behavior

The popup remains open.

• jQuery version: x.y
