I was working with Kendo ColorPicker and ColorPalette and I created a widget for serenity. Everything works perfect, except at the constructor time, I do not know the color. This is how is working now...

        // [KendoColorPickerEditor(Columns=2, Palette = "['#000', '#333', '#666', '#999', '#ccc', '#fff']",Buttons =true,Preview =true)]
        //Palette : "basic" | "websafe" | "['#000', '#333', '#666'] or leave blank"
        [KendoColorPickerEditor( Buttons = true, Preview = true)]
        public String Color
        {
            get { return Fields.Color[this]; }
            set { Fields.Color[this] = value; }
        }

A refresh method is needed to reload the properties changed after constructor...like the "Color" property

The Kendo UI ColorPicker's contrastTool shows the contrast ratios necessary to reach a certain accessibility level. While the current contrast ratio itself is localized, the thresholds for the AA and AAA levels are not. For languages like German, this means that for the ratio, "," is used as a decimal separator while the thresholds below use ".".

Bug report

According to the accessibility spec, when the ColorPicker's popup is open, and the focus is on the last focusable element, pressing tab should focus the first focusable element in the popup. Instead, the focus moves out of the popup, to the next focusable element on the page.

Reproduction of the problem

1. Open the Keyboard Navigation demo - https://demos.telerik.com/kendo-ui/colorpicker/keyboard-navigation
2. Open either of the ColorPickers
3. Press tab until you focus the last focusable item in the popup

Current behavior

Pressing tab again moves the focus out of the popup

Expected/desired behavior

Pressing tab should preserve the focus within the ColorPicker, to the first focusable item
