Description

The value for the specified index.

Remarks

Value is the key that associates symbols with features.

When there is no grouping, meaning that each category is defined by a single value-symbol pair, then you can look up the symbol for a given feature by using the Symbol property and passing the value. If there is grouping -- meaning that more that one value is associated with the same symbol -- then you need to additionally check to see if the value has a ReferenceValue. If it does, to access the symbol that the feature will be drawn with, use the Symbol property and pass the ReferenceValue of the value.
