Hi,

if you load the signature component when the mobile device is in vertical position and then rotate the device in the horizontal position the component doesn't detect changes and the signature capture doesn't work as it should (there is a span between the mouse/pen and the signature line).  The same also happens in browser if you change the browser window size so much that the signature component window shrink. I noticed a strange behaviour in signature popup on my project, but you may also try it on your demo component: https://demos.telerik.com/kendo-ui/signature/index .

Thanks

Consider the following scenario: There is a sortable Kendo-UI grid with a corresponding dataSource. Initially, the dataSource contains some items. When updating the dataSource to an empty array, all items disappear from the grid - so far, so good. However, if a column header is clicked afterwards to sort that column, the removed data reappears again.

We created a small "walkthrough" in this DOJO to demonstrate the issue.

FYI: The issue can be avoided by using a custom implementation of dataSource.transport.read which always returns the latest data.

The Typescript definitions for Kendo UI define the kendo.ui.ToolBarOpenEvent as follows:

interface ToolBarEvent {
        sender: ToolBar;
        preventDefault: Function;
        isDefaultPrevented(): boolean;
}

interface ToolBarOpenEvent extends ToolBarEvent {
        SplitButton?: JQuery | undefined;
}

The event is also documented that way in https://docs.telerik.com/kendo-ui/api/javascript/ui/toolbar/events/open. However, the corrersponding method in kendo-toolbar.js:446-453 does the following:

open: function (e) {
    var isDefaultPrevented = that.toolbar.trigger(OPEN, { target: element });
    if (isDefaultPrevented) {
        e.preventDefault();
        return;
    }
    that.adjustPopupWidth(e.sender);
},

Currently, the Kendo UI Toolbar supports adding icons to items by setting the "icon" property as documented here. However, only Kendo's own icons are supported.

In other widgets (like the Grid), adding custom icons (to a toolbar!) is already possible by specifiying an icon class.

However, if you wanted a third-party icon (or one of your own) directly to a standalone Toolbar, you would need to create a whole new template from scratch or replace the DOM element after rendering or use some hacky approach like demonstrated in this DOJO. While the first one means a lot of work, the latter ones are both not very stable.

Therefore, I propose to extend the icon support for Toolbars in general. I can think of two different solutions:

1. Let the developer specify an icon class (like in the Grid) that is then written into the DOM.
2. Let the developer specify some sort of "content template" that is displayed e.g. in a button or a splitButton. This way any content may be displayed in a toolbar item and this also allows for more complex and customized styling regarding the layout of e.g. icon and text.

Pivotgridv2 measure is not slicing the data by the second attribute when expanding

Bug report

In the Scheduler, if we have a slotTemplate and at the same time views.virtual, the resources().field in the slotTemplate always returns the same value (of the first resource).

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/lJnddiLz

Current behavior

The data-resource='#= resources().user_id #' in the slotTemplate always has the same value.
If the virtual is disabled, the data-resource='#= resources().user_id #' has a value based on the resource.

Expected/desired behavior

The resources should be correctly returned in the slotTemplate even if the virtual option is enabled.

If you create a grid with editable set to true, selectable set to one of the multiple options ("multiple, row" or "multiple, cell"), batch set to true and a column with editing disabled (either through the model or through the columns editable property), then when you update an editable cell and click the non-editable cell in the same row the "Save changes" and "Cancel changes" buttons do not appear.

See https://dojo.telerik.com/zAKmmTEU and attached example.html.zip

Notes:

Editable is disabled using a JavaScript function for UnitsInStock

{ field: "UnitsInStock", title: "Units In Stock", width: 120, editable: function() { return false; } },

Editable is set to false in the schema model for Discontinued

Discontinued: { type: "boolean", editable: false },

In this example, if you change the value of a UnitPrice cell and then click one of the non-editable cells (UnitsInStock or Discontinued) in the same row, the UnitPrice cell will be marked as dirty, but the "Save changes" and "Cancel changes" buttons will not appear.

This appears to happen because of the following:

• The focusout event is triggered on the grid.
• The closeCell method is called from the tap event registered on the cell.
• The _destroyEditable method is called within the closeCell method.
• The _editContainer field is set to null in the _destroyEditable method.
• The closeCell method is called again from within the editCell method but returns early because the _editContainer field is null.
• The timeout anonymous method from the focusout event handler is called, but the _toggleToolbarEditingItemsVisibility method is not called because _editContainer is null.
