AddSymbolLayerDrawing Method (GroupLayer)

In This Topic

Add Symbol Layer Drawing, SLD, to the group layer. After adding SLD it will be enabled. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

Public Sub AddSymbolLayerDrawing()

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.
System.InvalidOperationException	SLD cannot be added to this layer

Remarks

Use CanAddSymbolLayerDrawing to determine if the group layer can have SLD added. If SLD cannot be added an System.InvalidOperationException will be thrown.
Note: Adding SLD to a group layer will set any feature layers within the group that already had SLD added back to their default settings.

Example

Add SLD

QueuedTask.Run(() =>
{
  //check if it can be added to the layer
  if (featLayer.CanAddSymbolLayerDrawing())
    featLayer.AddSymbolLayerDrawing();

  //ditto for a group layer...must have at least
  //one child feature layer that can participate
  if (groupLayer.CanAddSymbolLayerDrawing())
    groupLayer.AddSymbolLayerDrawing();
});
