    When the color picker is on a tab that is not active when the page loads the cursor (crosshair) is not in the right location.  The color is correct, the cursor is not.  I tried a few things I saw in this forum, repainting clientside when the tab becomes active, and adding this script to the bottom of the page.  But no luck.  Any Ideas?  Thank you.  Telerik version = 2017.3.913.45

    function OnClientActiveTabChanged()
        $find("<%=colorBackGround.ClientID %>").repaint();
    Telerik.Web.UI.RadColorPicker.prototype._updateHslSliderBackground = function (hsl, isCustomColor)
                var color = this._hslToRgb(hsl.h, hsl.s, 0.5);
                var slider = isCustomColor ? this.get_millionCustomColorsSlider() : this.get_millionColorsSlider();
                if (slider._trackElement)
           = this._rgbValuesToHex(color.r, color.g, color.b);

    Hi Steven,

    You can force the colorPicker to update the color of its HSV palette whn the tab is changed, by setting the desired color again in a similar way:

                function onTabSelected(s, e) {
                    var picker = $find("<%=colorBackGround.ClientID %>");
