Description
This sample shows how you can use the edit toolbar to edit graphics on the map.
The toolbar is not a user interface component that you automatically see on the page. Instead, it's a helper class that you can use to allow users to edit graphics on the map. It saves you the effort of writing the code for editing, moving, scaling and rotating geometries.
To test this sample:
- Specify the types of operations you want to perform, you can opt to edit vertices and move, rotate or scale graphics.
- Click on a graphic to activate the edit toolbar.
- Modfiy the graphic.
- Click outside the graphic to deactivate the toolbar.
