Hi Team,

I would like to request a way/demo to have AutoSync for the dataSource and be able to stay in edit mode in the Kendo UI Grid. 

Thank you!

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.

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);
},
