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.

Bug Description

When you add a filter to a column on the spreadsheet component, only the down arrow icon part of the filter button is clickable, not the entire button.

Steps to Reproduce

1. Open the Dojo - https://dojo.telerik.com/dmrXJIdC
2. Try to click on the filter buttons (.k-spreadsheet-filter)

Expected Behavior

The filter menu is not opened unless we click on the icon.

Actual Behavior

The filter menu should open when the button is clicked.

• Create e.g. local data grid (id, name)
  
• add 2 records => { id: 1, name: "null", id: 2, name: "Jack" }
• Name column for id = 1 is empty

I have tested this on your example for local data grid. It can be applicable also for remote grid, treelist, etc.

Currently, filter logic is not translated in the expression preview. A `messages` property needs to be added for adjusting the logic
