SetAnchorPoint Method (Element)

In This Topic

Sets the element anchor point to the X and Y location specified. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Visual Basic (Declaration)
C#

Public Overridable Sub SetAnchorPoint( _
   ByVal anchorPoint As Coordinate2D _
)

public virtual void SetAnchorPoint( 
   Coordinate2D anchorPoint
)

Parameters

anchorPoint: The new anchor point location

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method must be called within the lambda passed to QueuedTask.Run.
System.InvalidOperationException	This element requires its mapview to be active

Remarks

Placement for an element contained in graphics layer requires the mapview be active.
. Use SetX and SetY to change the anchor point X and Y individually. Changing the element anchor point location does not change its anchor position relative to its element. Anchor position is modified via SetAnchor.

Example

Move Graphic Elements

{
  // Note: must be called on the QueuedTask
  {
    //Each selected element will move to a set distance to the upper right.
    var selElements = graphicsLayer.GetSelectedElements();
    if (selElements.Count == 0) return;
    //Move the element up
    foreach (var selElement in selElements)
    {
      //Get the element's bounds
      var elementPoly = PolygonBuilderEx.CreatePolygon(selElement.GetBounds());
      //get the coordinates of the element bounding envelope.
      var pointsList = elementPoly.Copy2DCoordinatesToList();
      //Move the element's Anchor point to the upper right.
      selElement.SetAnchorPoint(pointsList[1]);
    }
  }
}
