ESRI.ArcGIS.ADF.Web.Display.Renderer Namespace > UniqueValueRenderer Class : ValueColumnName3 Property

Third lookup column name in the data table used to determine what symbology to display.


Visual Basic (Declaration) 
Public Property ValueColumnName3 As String
Visual Basic (Usage)Copy Code
Dim instance As UniqueValueRenderer
Dim value As String
instance.ValueColumnName3 = value
value = instance.ValueColumnName3
public string ValueColumnName3 {get; set;}


This property may optionally be set to specify a third column in a graphics layer to compare with the Values of the renderer. This enables symbolizing features by unique combinations of values in three different columns of the graphics layer.

If set, the ValueColumnName3 must match the name of a column in the table of the FeatureGraphicsLayer. This column contains a value for each feature that is looked up in the Generic ValueCollection of the renderer, by splitting the UniqueValue's Value based on the ValueDelimiter. If the values match for this column and the ones specified in ValueColumnName and ValueColumnName2, the symbol of the Value is used to display the graphic feature. If not found, the Generic ValueMapRenderer.DefaultSymbol is used (if set).
