Libraries Google Maps

@AC_9552412 , 
From the screen capture you added code to "googlemap.ide.js". 

There should also be code added to "googlemap.runtime.js" which makes the approate updates.

The updates include adding the option "drawingControl: true," to options when the item is checked. 

You also added the drawing library:

googleMapsConnectionString = _invoker.result.rows[0].GetGoogleMapsConnectionString + "&libraries=drawing";

When defining an instance of the Google Map you need to create an instance of the map object. This looks like 

 = new google.maps.Map(document.getElementById("map"),

from the Google Maps Documentation. When reviewing the "googlemap.runtime.js" we find:

thisWidget.map = new google.maps.Map(document.getElementById(thisWidget.jqElementId), options);

This creates a Google Map object. From the google documents you need to load the drawing manager. You need to add code which looks like:

thisWidget.drawingManager = new google.maps.drawing.DrawingManager({
 drawingMode: google.maps.drawing.OverlayType.MARKER,
 drawingControl: true,
 drawingControlOptions: {
 position: google.maps.ControlPosition.TOP_CENTER,
	drawingModes: [
	google.maps.drawing.OverlayType.MARKER,
	google.maps.drawing.OverlayType.CIRCLE,
	google.maps.drawing.OverlayType.POLYGON,
	google.maps.drawing.OverlayType.POLYLINE,
	google.maps.drawing.OverlayType.RECTANGLE,
	],
 },
 markerOptions: {
 icon:					"https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png",
 },
 circleOptions: {
	fillColor: "#ffff00",
	fillOpacity: 1,
	strokeWeight: 5,
	clickable: false,
	editable: true,
	zIndex: 1,
 },
});
thisWidget.drawingManager.setMap(thisWidget.map);

The above is based on the Google Maps https://developers.google.com/maps/documentation/javascript/examples/drawing-tools

Let me know if you have any questions.
