Bug report

Clicking inside the content of a modal Window with an iframe and then closing the Window does not remove the k-state-focused class from the Window wrapper.

Reproduction of the problem

  1. Run this dojo
  2. Click the Open Window button
  3. Click inside to content of the Window
  4. Close the Window

Current behavior

The window widget wrapper still has a k-state-focused class:

<div class="k-widget k-window k-state-focused" data-role="draggable" style="visibility: visible; display: none; padding-top: 45px; min-width: 90px; min-height: 50px; z-index: 10004; transform: scale(0.7);">

Expected/desired behavior

k-state-focused class should be removed upon closing of the Window

This can be currently observed here:

The "g" in the window title is truncated.

  Hi Team


We found a bug when we try to dynamically include a title at the KendoUI - Window component.

When we visit the website, all is correctly(title.png) displayed. After an reload of the website (F5 or the refresh button) the title disappers(notitle.png)


Regrets Thomas

ViewModel (TypeScript/Aurelia):
	//private variable
	private _helpWindowTitle: string;

	constructor(private _taskQueue: TaskQueue) {
		//set localization
			.then(() => {
				this._helpWindowTitle ="window.title");

View (HTML):

<div id="helpwindow" ak-window="k-width: 600px;
				k-visible.bind: false;
				k-title.two-way: _helpWindowTitle;
				k-actions.bind: _helpActions;
				k-widget.bind: _helpwindow">
		<form class="d-flex-center flex-column" role="form" ref="form" submit.delegate="tryHelpRequest()">
			<div class="form-group d-flex-center m-4">
				<label class="white-space-nowrap m-0 mr-2"><span t="window.optionlabel"></span></label>
				<ak-drop-down-list k-auto-bind.bind="false"

I have a scrollable div within kendo Window.

The said div contains selectable thumbnail, it will show a bigger version if clicked (functionality not included in the attached file)

The problem when there will be hundreds to thousands of images the scrolling in IE11 becomes almost unresponsive.

Attached sample have around a 1000.

Tested it with bootstrap modal, did not have any issue with scrolling in IE11.

Issue does not happen in other browsers, is this an issue with repaint and scroll in IE?

Bug report

When there are multiple Window components initialized in one page the initially defined z-index is not changing when tapping on a given Window on an iPad device in the Safari browser.

Reproduction of the problem

  1. Open this Dojo example on an iPad
  2. Drag the upper Window(Number 3) aside and tap on the second one

Possible fix
wrapper.add(wrapper.children('.k-resize-handle,' + KWINDOWTITLEBAR)).on('mousedown' + NS, proxy(that.toFront, that));


wrapper.add(wrapper.children('.k-resize-handle,' + KWINDOWTITLEBAR)).on('mousedown' + NS, proxy(that.toFront, that)).on('touchstart' + NS, proxy(that.toFront, that));

Current behavior

The second Window continues to stay under window number 3

Expected/desired behavior

Once a given Window is tapped its should pop to the top and its content shouldn't be hidden by other Windows.

  • Open the linked above Dojo project in Chrome for iPad and see the correct behavior

I use Windows as a sliding pane. How do I make the window still the default size when the window is minimized and then restored?
