Reproduction of the problem

Bug report

The DropDownList stretches to adapt to the length of the selected item.

Reproduction of the problem

1. Run this Dojo
2. Change the selected item

Expected/desired behavior

The width of the DropDownList should be consistent.

Environment

• Kendo UI version: 2023.1.314

Bug report

Reproducible in Chrome and Firefox. Not reproducible in IE11.

Reproduction of the problem

Dojo example.
There are two Menus. In the first one navigation is triggered from the function passed to the "Sub Item 2" item's url option. In the second Menu navigation is triggered in the Menu's select event handler.

1. Hover "Item 2" and click "Sub Item 2"
   The wiki page will open in a new tab.
2. Check the Menu in the original tab with the dojo.

Current behavior

Doing this in the first Menu, results in the submenu remaining open.

Expected/desired behavior

The submenu should close in both scenarios, since closeOnClick is enabled by default and the select event fires before triggering the navigation.

Bug report

Related to daylight saving: in the US on14 March, 2021, at 2:00AM the clocks are moved 1h forward.

Reproduction of the problem

Dojo example.

1. Set the computer's timezone to Pacific (US/Canada).
2. Double click the 2:00AM or the 2:30AM slot to add a new event.

Current behavior

The selection is moved 1h back to 1:00AM (or 1:30AM respectively) and the event is created at this time.

Expected/desired behavior

The event should be created at 3:00AM. This will be consistent with the way Outlook handles daylight saving - in a new meeting if you select 2:00AM as a start time, it is automatically changed to 3:00AM.

I have a screen that I'm manually calling the print functionality of the kendo-pdfviewer from a button click.   It is working, but the problem is that the resulting print dialog window is really small.   Even if I open the print dialog, resize the dialog, and then try to print again it gets reset to the original small size.  This is preventing our users from previewing what the resulting page will print like.   



This is the code for my pdf viewer

<div class="row">
    <div class="col">

        <div id="example">

            <kendo-pdfviewer name="pdfviewer" height="300">
                <pdfjs-processing file="@(Url.Page("/Badges/Details", "VisitorBadge", new { BadgeId = @Model.Id }))" />
                <toolbar enabled="false">
                    <pdfviewer-toolbar-items>
                        <pdfviewer-toolbar-item command="PrintCommand" type="button" name="print" icon="print"></pdfviewer-toolbar-item>
                    </pdfviewer-toolbar-items>
                </toolbar>
            </kendo-pdfviewer>
        </div>

        <style>
            html body #pdfviewer {
                width: 100% !important;
            }
        </style>
    </div>
</div>

    badgereport.onWindowOpen = function () {
        $pdfviewer = $("#pdfviewer").data("kendoPDFViewer");
        $printBadgePdf = $("#printBadgePdf");
        $closeBadgePdf = $("#closeBadgePdf");
        $badgeWindow = $("#badgeWindow").data("kendoWindow");

        $printBadgePdf.on("click", function (e) {
            e.preventDefault();
            $pdfviewer.execute({ command: "PrintCommand" });

        });
        $closeBadgePdf.on("click", function (e) {
            e.preventDefault();
            $badgeWindow.close();
        });

    };

I am seeing that once a grid checkboxlist column filter exceeds about 1000 items the wait time appears to increase non-linearly (performance is worse than linear.)  For example, with 3,000 items the page freezes for about 30 seconds.  The data is fetched in under 50 milliseconds, so the vast majority of this time appears to be processing by Kendo.

Please see the attached for my configuration.

In the ThemeBuilder the controls do not use the latest version.

For instance while playing around with the ThemeBuilder I noticed that the primary button does not look primary like on the demos page.

Also it would be helpful to provide a page where you explain where every color is used.

Bug report
For the Telerik Scheduler Timeline View, since the update from somewhere in between version 2022.3.1109 to 2024.2.154, a custom timeline view cannot be selected if the view name has dot(s) in its name (e.g. "kendo.ui.customTimelineView").

Reproduction of the problem

Add a custom Timeline View by extending the kendo.ui.TimelineView

Current behavior

Unlike older versions (I know that it worked with version <= 2022.3.1109, but don't know when exactly it was introduced)  now the ui blocks, when the custom select view button is clicked. Specifically, the problem is in kendo.scheduler.js at line 4554:

var viewElementToSelect = that.toolbar.find("[" + kendo.attr("name") + "=" + name + "]");

Expected behavior

In this code line, the find method does not work when the variable "name" contains something like "kendo.ui.CustomTimelineView". As a solution, I suggest escaping the name beforehand:

var nameEscaped = $.escapeSelector(name);
var viewElementToSelect = that.toolbar.find("[" + kendo.attr("name") + "=" + nameEscaped + "]");

Bug report

When the setOptions of the Slider is applied with or without parameters the navigation of the Slider with the mouse breaks unless the resize() method is called immediately after.

Reproduction of the problem

1. Open this Dojo
2. Click the Without resize button
3. Navigate the Slider with the mouse

Note that even if the With resize button is subsequently clicked the behavior persists

Current behavior

Slider.setOptions() breaks mouse navigation of the Widget

Expected/desired behavior

Slider.setOptions() should call the resize method internally to prevent the issue
