Hi team,
I found that since 2022 R2, the height of a multiselect varies when adding tags. From 30px height with no values to 32px height with one or more tags.
https://dojo.telerik.com/UVUSaSIn
As a result, there is a nasty pumping effect in the page.
Please advise,
Best regards,
Laurent.

We updated Kendo UI for JQuery from v2021.2.511 to v2022.1.325 and we observed that certain screen reader functions were broken.
The following issues were observed when screen reader is activated on any KendoMultiSelect control:
a. The selected item and tag are not being announced. The selected item and the tag were announced by narrator before the update.
b. The number of available suggestions is not announced. This was announced before the update.
c. When scan mode is activated, users cannot navigate the list items using the up/down arrow keys.
d. When a user enters a search string that is not in the datasource, narrator does not announce that. Before the update, narrator would announce "Selection contains zero items".
For other controls like checkboxes, narrator does not announce the name or label of the controls when in focus.
Is there a different attribute other than aria-label that we need defined on these controls to get screen readers to announce them?
I'd appreciate any help to get these issues fixed.
Thanks!
OS: Windows 11
Browser: Edge Chromium.

I have some model with selected ids:
class Model{ public IList<int> SelectedIds { get; set; }}in my partial view I render Multiselect control:
@(Html.Kendo().MultiSelectFor(f => f.SelectedIds) .Name("SelectedIds") .Placeholder("​Select Items...") .Filter(FilterType.Contains) .IgnoreCase(true).TagMode(TagMode.Single) .TagTemplate("<span>​Selected #=data.dataItems.length# ​from #=data.maxTotal#</span>") .DataSource(a => a.Read("Get​ItemsListAction", "​Controller")) .DataValueField("Id") .DataTextField("Value") .AutoClose(false))and it renders next wrong Javascript code (see value of the "value" at the end of the expression :):
jQuery(function(){jQuery("#SelectedIds").kendoMultiSelect({"dataSource":{"transport":{"read":{"url":"/sspd/​Controller/Get​ItemsListAction"},"prefix":""},"schema":{"errors":"Errors"}},"dataTextField":"Value","filter":"contains","ignoreCase":true,"tagMode":"single","tagTemplate":"\u003cspan\u003e​Selected#=data.dataItems.length# ​from #=data.maxTotal#\u003c/span\u003e","autoClose":false,"dataValueField":"Id","placeholder":"Select Items...","value":["System.Collections.Generic.List`1[System.Int32]"]});});BUT!
When I change the Name in Razor code to something other name, for example, "bla-bla-bla" it renders correct code and I see in the web page multiselect with selected items:
jQuery(function(){jQuery("#bla-bla-bla").kendoMultiSelect({"dataSource":{"transport":{"read":{"url":"/sspd/​Controller/Get​ItemsListAction"},"prefix":""},"schema":{"errors":"Errors"}},"dataTextField":"Value","filter":"contains","ignoreCase":true,"tagMode":"single","tagTemplate":"\u003cspan\u003eSelected#=data.dataItems.length# from #=data.maxTotal#\u003c/span\u003e","autoClose":false,"dataValueField":"Id","placeholder":"Select Items...","value":[28620,32216]});});In other words, rendered javascript is incorrect when Model's property for the selected ids is the same with parameter value passed to Html.Kendo().MultiSelect().Name method
Whats wrong in my code?

Hi there
This is more a kind of bug, but I found no way to create a ticket....
I'm using the multiselect widget to let the user select multiple or all persons. We're talking about around 300 - 400 entries. In some cases all persons need to be selected. So I get all the data items and set them with the value() method on the widget. But this takes "ages" (2-3 sec) and even leads to no responding script error on some computers. Firebug profiler revealed, that about half of the needed time is consumed by the _select() method of the multiselect better said, its "that._height(that._visibleItems);" line. If I move this line to the value() method and insert it after the select loop, the time consumption drops by more than half.
I don't see a reason why the height needs to be calculated on every loop step. But this is probably needed in some other cases. Still I would recommend to make this more streamline by calculating the height after value setting has completed.

I just worked through adding a MultiSelect fillter on a page with a grid, and didn't see anything in the forums that addressed this issue, so I thought I would post the result that I came up with.
Above is what I came up with.
Telerik came up with the following:
Hopefully, this will be helpful to somebody.
<%= Html.Kendo().MultiSelectFor(m => m.FilterRoleIds) .Placeholder("Select Roles") .DataTextField("RoleName") .DataValueField("ApRoleId") .BindTo(ViewBag.ApRolesList)%> <%= Html.Kendo().MultiSelectFor(m => m.FilterCompanyIds) .Placeholder("Select Companies") .DataTextField("CompanyName") .DataValueField("CompanyId") .BindTo(ViewBag.CompanyList)%> <script language="javascript" type="text/javascript"> function additionalData() { return { roleIds: "<%= ApRoleController.ReturnListValues(Model.FilterRoleIds) %>", companyIds: "<%= ApRoleController.ReturnListValues(Model.FilterCompanyIds) %>" }; }</script> public static string ReturnListValues(List<string> list) { if (list == null || list.Count == 0) return ""; string s = string.Empty; foreach (var item in list) { if (s != string.Empty) s += ","; s += item; } return s; }Telerik came up with the following:
<script language="javascript" type="text/javascript"> function additionalData() { var roleIds = <%= Html.Raw(Json.Encode(Model.FilterRoleIds)) %>; var data = {}; for(var i=0; i< roleIds.length;i++){ data["FilterRoleIds[" + i + "]"] = roleIds[i]; } return data; }</script>
