Hello dear support,

I ve a strange behavior that I may qualify as bug.

I ve tried to reproduce here https://dojo.telerik.com/osEPIvOG wit a result shown in this animated gif here attached (DPSN-13445).

Basically what's happening is that if your are selecting / clearing elements that looked to be in different pages (view), the dataItems() function does not return the correct value, but some previous item.

This "bug" is always reproducible;

Please let me know if there is a bad implementation (I m using here basic Telerik sample) or if there is a workaround, or if I can expect a fix;

By advance thx for your swift reply.

Bug report

Reproduction of the problem

Dojo example.

1. Focus the MultiSelect and type in "c". The data is filtered and "Canada" is displayed in the list.
2. Select "Canada".
3. Click in the MultiSelect's input area.

Current behavior

The filter is cleared and all the items in the dataSource are listed, even though "c" remains in the input area.
If step 2 is omitted, the filter is not cleared.

Expected/desired behavior

The filter should not be cleared. After step 3 the MultiSelect should still show only "Canada" in the list of items.

Environment

• Kendo UI version: 2020.3.1118
• jQuery version: x.y

Bug report

In the MultiSelect widget preventing the default of the filtering event while minLength is set to more than 1 causes the value method to not be able to properly get and set values of the selected dataItems.

Reproduction of the problem

1. Open this Dojo
2. Type Cha and select an item
3. Click the Clear Value button

Current behavior

The Clear Value button is able to clear the selected values but is not updating to visualize the change in the Widget

Expected/desired behavior

The button Clear Value is expected to clear the selected values and visualize the change

Bug report

The MultiSelect is flickering several times when filtering and then selecting an item in Desktop mode on Safari.

Reproduction of the problem

1. Open the Virtualization demo in desktop mode in Safari on a touch device.
2. Filter the MultiSelect and select an item from the bottom of the filtered list.

Current behavior

The selected item flickers several times. (the selected item disappears and re-appears several times)

Expected/desired behavior

The selected item should not be flickering.

LS,

When the option highlightFirst is set to false and the autoBind is set to false, the first item is always highlighted.

 

Steps to reproduce:

Edit this example: https://demos.telerik.com/kendo-ui/multiselect/index

Add the parameters:

              highlightFirst: false,
              autoBind: false,

Click on the multiselect, the multiselect will open, but the first item is highlighted. Expected behaviour: first item not highlighted.

Change the autoBind to true or undefined, the first item isn't highlighted.

The problem with the first item highlighted is that this option will be selected when the user hits enter.

Is there any work around for this issue?

Thanks in advance.

Hi,

 

I am running in ti issue where extended MultiSelect selects primitive values after 1st value has been selected. See image blow and attached sample to recreate issue. Please also provide feedback regarding a way to mitigate this bug. 

Bug report

When an empty array is passed to the MultiSelect's value method inside the deselect event, the item that is deselected remains selected in the MultiSelect.

Reproduction of the problem

1. Open this Dojo and run it
2. Expand MultiSelect's popup list and click on "All" item.

Current behavior

The different MultiSelect items are deselected except for the "All" item.

*If the "if" statement is removed from the deselect event function in the Dojo, and only the 'e.sender.value([]);' is kept, the issue is reproducing no matter of the selected item in MultiSelect's popup.

Expected/desired behavior

Calling 'e.sender.value([]);' should remove all items selected in the MultiSelect.
Click on the "Clear values" button to see the expected behavior.

Environment

• Kendo UI version: 201x.r.ddd

Bug report

MultiSelect with virtualization and tagMode: single deselects items when too many items are selected.

Reproduction of the problem

1. Download and unzip the attached project.
2. Run the project.
3. Start selecting items from the first item on.

For convenience, attached is a small video demonstrating the behavior.

Note: So far I was unable to reproduce the issue in a Dojo example when trying to replicate the configuration from the project.

Current behavior

At some point, the dropdown popup will scroll up, and some items that have been selected, will be deselected. Also, the single tag for the selected items will disappear.

Expected/desired behavior

The component should not be deselecting items, should not scroll up and the tag should not disappear.

Environment

• Kendo UI version: 2020.1.406
• Browser: [all]

Bug report

MultiSelect with virtualization scrolls automatically to the first item in the dropdown after selecting items.

Note: the issue is reproduced inconsistently.

Reproduction of the problem

1. Open the Dojo example - https://dojo.telerik.com/oSuTUhiQ/4.
2. Scroll to e.g item 10296.
3. Start selecting all the items down.

Current behavior

At some point, the component will scroll to the top of the dropdown.

Expected/desired behavior

The component should not scroll to the top, the focus should stay on the currently selected item.

Environment

• Kendo UI version: 2020.2.513
• Browser: [all]

Bug report

In IE 11, MultiSelect with autoClose:false does not prevent the popup from closing. The widget has to be placed at the bottom of the page, so that there is no space for the popup to open below the input field.

Reproduction of the problem

1. Open this Dojo example.
2. Scroll to the bottom of the page.
3. Start selecting items until the tags do not fit the input field.
4. When the input's height expands, the popup closes.

Current behavior

The popup closes when the height of the input field expands to fit tags on a new line.

Expected/desired behavior

The popup should remain open.

Environment

• Kendo UI version: 2020.1.219
• Browser: [Internet Explorer 11]

Bug report

When a new item is added and the dataSource's sync method is called, the requestEnd event handler data (arg.type) returns the type of request as "read", instead of "create".
As a result the Add new item demo, does not work as expected, because it has a check for the type of the request in the requestEnd handler, and expects the request to be "create". Since the request type comes out as "read" the logic for selecting the newly added item is not executed.

In previous versions the request has been correctly identified as "create". The issue is exhibited only in the MultiSelect. The ComboBox and the DropDownList return the request as "create".

This behavior has been introduced in R3 2017. Reproducible in Chrome, Firefox and Chromium Edge. Not reproducible in IE11 and Spartan Edge.

As a workaround the addNew function can be modified as shown below:

function addNew(widgetId, value) {
    var widget = $("#" + widgetId).getKendoMultiSelect();
    var dataSource = widget.dataSource;

    if (confirm("Are you sure?")) {
        dataSource.add({
            ProductID: 0,
            ProductName: value
        });
      
        dataSource.one("sync", function() {
          var index = dataSource.view().length - 1;
          var newValue = dataSource.at(index).ProductID;
          
          widget.value(widget.value().concat([newValue]));
        });

        dataSource.sync();
    }
}

Reproduction of the problem

Dojo example.

1. Open the browser's console.
2. Focus the input and type in some random text.
3. Click the button in the popup to add a new item.
4. The type of the request returned by the requestEnd event data is logged in the console.

Current behavior

The event data returns "read" as the type of the request.

Expected/desired behavior

The event data returns "create" as the type of the request.

Add the ability to define cascadeFrom and the possibility to cascade from another widget e.g dropdown, combobox etc. 

The MultiSelect should preserve the order of selected items on a form post.

Hi Kendo support team,

I found a bug (or at least an undesired behavior) in the Kendo Multiselect widget.

After initialization the options in the existing select seem to be rebuilt receiving the content as value attribute if it did not exist before.
During this process potentially existing double spaces are replaced with single spaces (see attached image).

If the options of that select are replaced later, they will keep double spaces.

We use the selected values to receive content from the database, which in these cases is not possible anymore.
Since the content of the database is created by our client, we can't guarantee there might not be any double spaces.

In general I think that the content of the existing options should not be modified in any way.

 

Thanks,
Markus

See the following dojo to reproduce the behavior: https://dojo.telerik.com/oGEcaDoN

Currently, the relation between the MultiSelect input and its TagList element (the one that holds the selected items) is established with an aria-describedby attribute. That results in the screen readers to report the selection (all selected items) as one line of text which doesn't adequately describe the control or and its context. The text of each selected item is announced but it is not clear how many items are selected. Also, there is no articulation between each item text that is announced.

Consider and implement better relation/structure, so that the context of the widget (the selected items and their number) is announced clearly.

Hi,

We are using the Kendo Multi Select widget, and it was just reported that you can't remove a tag from the list when clicking on the Close (X) icon when using Safari on iPadOS 13.1.3. I was also able to reproduce this on the multiselect demo here - https://demos.telerik.com/kendo-ui/multiselect/index. We are currently on version 2019.2.619, however I also tried it on the latest with the demo and it also didn't seem to work.

Is this a known defect? 

Thanks,

Emily

There is no way to sort the selected items inside the MultiSelect. 

It would be nice to have such functionality implemented or provide an implementation that can achieve the described functionality.

Bug report

Regression since R1 2018 SP1.

Reproduction of the problem

Dojo example.

1. Focus the MultiSelect

Current behavior

The value set in the dataBound event handler is replaced by the value set initially in the widget's options.

Expected/desired behavior

The widget should keep the value set after initialization (["AROUT", "BERGS"]) when focused.
