Layout or GroupElement
Envelope
String
CIMTextSymbol
Creates a graphic rectangle text element on a layout from an envelope geometry with an added parameter to set the text symbol. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
Overloads Function CreateRectangleParagraphGraphicElement( _
   ByVal elementContainer As ILayoutElementContainer, _
   ByVal envelope As Envelope, _
   Optional ByVal text As String, _
   Optional ByVal textSymbol As CIMTextSymbol _
) As GraphicElement

Parameters

elementContainer
Layout or GroupElement
envelope
Envelope
text
String
textSymbol
CIMTextSymbol

Return Value

Returns a GraphicElement.
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Remarks
If the element container is a Layout then the element gets added to the root level of the layout TOC at the top most position. If the element container is a GroupElement then it gets added to the group at the topmost position.
Example
//Create rectangle text with background and border symbology.  

//Construct on the worker thread
await QueuedTask.Run(() =>
{
  //Build 2D polygon geometry
  List<Coordinate2D> plyCoords = new List<Coordinate2D>();
  plyCoords.Add(new Coordinate2D(3.5, 7));
  plyCoords.Add(new Coordinate2D(4.5, 7));
  plyCoords.Add(new Coordinate2D(4.5, 6.7));
  plyCoords.Add(new Coordinate2D(5.5, 6.7));
  plyCoords.Add(new Coordinate2D(5.5, 6.1));
  plyCoords.Add(new Coordinate2D(3.5, 6.1));
  Polygon poly = PolygonBuilder.CreatePolygon(plyCoords);

  //Set symbolology, create and add element to layout
  //Also notice how formatting tags are using within the text string.
  CIMTextSymbol sym = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.GreyRGB, 10, "Arial", "Regular");
  string text = "Some Text String that is really long and is <BOL>forced to wrap to other lines</BOL> so that we can see the effects." as String;
  GraphicElement polyTxtElm = LayoutElementFactory.Instance.CreatePolygonParagraphGraphicElement(layout, poly, text, sym);
  polyTxtElm.SetName("New Polygon Text");

  //(Optionally) Modify paragraph border 
  CIMGraphic polyTxtGra = polyTxtElm.Graphic;
  CIMParagraphTextGraphic cimPolyTxtGra = polyTxtGra as CIMParagraphTextGraphic;
  cimPolyTxtGra.Frame.BorderSymbol = new CIMSymbolReference();
  cimPolyTxtGra.Frame.BorderSymbol.Symbol = SymbolFactory.Instance.ConstructLineSymbol(ColorFactory.Instance.GreyRGB, 1.0, SimpleLineStyle.Solid);
  polyTxtElm.SetGraphic(polyTxtGra);
});
