Hello!

Prior to 2024.2.514 (2024 Q2), the DateRangePicker would "force users first to select start and then end range regardless of the date input selected" [1,2]. However, with the latest 2024 Q2 release, clicking the End input on the DateRangePicker selects the range end.

I did not see this specifically mentioned in the release notes, https://www.telerik.com/support/whats-new/kendo-ui/release-history/kendo-ui-for-jquery-2024-2-514-(2024-q2), so I am reporting this as a bug.

Here is a basic Dojo to demonstrate: https://dojo.telerik.com/IWAbUpuV. You can see the previous behavior by changing the library to the previous version (2024.1.319).

However, when the filter is reopened, the second DatePicker is automatically populated with the value from the first DatePicker. The issue occurs since version 2025.1.211.

Environment

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);
},

Bug report

When attempting to validate a cell value against a predefined finite list, the validation process fails to recognize valid entries that are present in the list. Instead, it incorrectly flags them as invalid. The issue occur when there is an empty space before the first value in the 'from' option.

Reproduction of the problem

1. Run the Dojo - https://dojo.telerik.com/@NeliK/icizisEF

Current behavior

On the first row, the 'YES' in the B1 cell is marked as invalid although it is present in the list with the valid values. the difference between row 1 and row 4 is the empty space in the validation from configuration:

"from": "{ \"YES\", \"NO\"}", //row 1
"from": "{\"YES\", \"NO\"}" //row 4

Expected/desired behavior

The empty space added in the from configuration option should not affect the validation. If the cell value is present in the list, it should be marked as valid.
