Visual Basic (Declaration)

Visual Basic (Usage)

C#

dt: DataTable to convert to a graphics layer.

symbolColor: Color with which to render the features in the graphics layer.

selectedSymbolColor: Color with which to render features that may be selected in the graphics layer.

highlightSymbolColor: Color with which to render highlighted features in the graphics layer. This only applies when the graphics layer has RenderOnClient set to true.

selectFeatures: Whether the inital IsSelected state of features should be set to true.

Converts a System.Data.DataTable to an ESRI Web ADF graphics layer.

public static GraphicsLayer ToGraphicsLayer( DataTable dt, Color symbolColor, Color selectedSymbolColor, Color highlightSymbolColor, bool selectFeatures )

Parameters

dt: DataTable to convert to a graphics layer.
symbolColor: Color with which to render the features in the graphics layer.
selectedSymbolColor: Color with which to render features that may be selected in the graphics layer.
highlightSymbolColor: Color with which to render highlighted features in the graphics layer. This only applies when the graphics layer has RenderOnClient set to true.
selectFeatures: Whether the inital IsSelected state of features should be set to true.

Return Value

ESRI Web ADF graphics layer.

Remarks

In order for conversion to a graphics layer to occur properly, the DataTable must contain a geometry or a graphics column. If it doesn't, this method will return null. If the data table contains a column of type ESRI.ArcGIS.ADF.Web.Geometry.Geometry and all rows contain the same geometry type (point, line or polygon), then the output layer will be a feature graphics layer (ESRI.ArcGIS.ADF.Web.Display.Graphics.FeatureGraphicsLayer). Otherwise, the output layer will be an element graphics layer. (ESRI.ArcGIS.ADF.Web.Display.Graphics.ElementGraphicsLayer).
