CreatePointGraphicElement Method

Creates a graphic point element on a layout from a single 2D coordinate. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public GraphicElement CreatePointGraphicElement( 
   ILayoutElementContainer elementContainer,
   Coordinate2D coord2D,
   CIMPointSymbol ptSymbol
)

Public Function CreatePointGraphicElement( _
   ByVal elementContainer As ILayoutElementContainer, _
   ByVal coord2D As Coordinate2D, _
   Optional ByVal ptSymbol As CIMPointSymbol _
) As GraphicElement

Parameters

elementContainer: Layout or GroupElement
coord2D: Coordinate2D
ptSymbol: CIMPointSymbol

Return Value

Returns a GraphicElement.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method must be called within the lambda passed to QueuedTask.Run.
System.InvalidOperationException	Map has reached maximum graphics count limit of 4000 elements. One or more elements cannot be created.
System.InvalidOperationException	Map has reached maximum graphics size limit of 10 MB. One or more elements cannot be created.

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 a simple 2D point graphic and apply an existing point style item as the symbology.

//Construct on the worker thread
await QueuedTask.Run(() =>
{
  //Build 2D point geometry  
  Coordinate2D coord2D = new Coordinate2D(2.0, 10.0);

  //(optionally) Reference a point symbol in a style
  StyleProjectItem ptStylePrjItm = Project.Current.GetItems<StyleProjectItem>().FirstOrDefault(item => item.Name == "ArcGIS 2D");
  SymbolStyleItem ptSymStyleItm = ptStylePrjItm.SearchSymbols(StyleItemType.PointSymbol, "City Hall")[0];
  CIMPointSymbol pointSym = ptSymStyleItm.Symbol as CIMPointSymbol;
  pointSym.SetSize(50);

  //Set symbolology, create and add element to layout

  //An alternative simple symbol is also commented out below.  This would elminate the four 
  //optional lines of code above that reference a style.

  //CIMPointSymbol pointSym = SymbolFactory.Instance.ConstructPointSymbol(ColorFactory.Instance.RedRGB, 25.0, SimpleMarkerStyle.Star);  //Alternative simple symbol
  GraphicElement ptElm = LayoutElementFactory.Instance.CreatePointGraphicElement(layout, coord2D, pointSym);
  ptElm.SetName("New Point");
});
