A graphic or an array of graphics to be updated. Only graphics added to SketchViewModel’s layer property can be updated.

updateOptions SketchViewModelUpdateUpdateOptions

• updateOptions.tool: Name of the update tool. Specifies the update operation for the selected graphics. The provided tool will become the activeTool. Possible Values
  Value | Description |
  —– | ———– |
  transform | This is the *defaulttool for graphics with a polygon geometry, polyline geometry or graphics that use a 3D object symbol layer with a point geometry. It allows one or multiple graphics to be scaled, rotated and moved by default. Its default behavior can be changed by setting the enableRotation, enableScaling or preserveAspectRatio arguments when calling the update method or setting them on the defaultUpdateOptions property when the Sketch widget initializes.
  reshape | This tool allows the entire graphic or individual vertices of the graphic to be moved. Vertices can be added or removed. This tool can only be used with a single graphic that has a polygon or polyline geometry.
  move | This is the *defaulttool for graphics with a point geometry that do not use a 3D object symbol layer. It should be used for specific cases where you just want to move selected polygon and polyline graphics without additional options. Additionally, the move tool does not support toggling to different modes, since the move operation is built into both the transform and reshape tools by default.
• updateOptions.enableScaling: Indicates if the scale operation will be enabled when updating graphics. Only applies if tool is transform.
• updateOptions.multipleSelectionEnabled: Indicates whether more than one selection can be made at once. This applies to the shift+click interaction with the transform tool.
• updateOptions.toggleToolOnClick: Indicates if the graphic being updated can be toggled between transform and reshape update options.

Returns

System.Threading.Tasks.Task
