Criteria Property

Gets a collection of individual IColorConditionValue objects. Read-only.
ReadOnly Property Criteria As IList(Of IColorConditionValue)
Dim instance As IColorScale
Dim value As IList(Of IColorConditionValue)
value = instance.Criteria
IList<IColorConditionValue> Criteria {get;}
The default size of the criteria list is 2 and it can be changed using SetConditionCount method. To know more about Conditional formatting Types refer this link.
The criteria for applying color scale can be accessed from the Criteria Property. The following code illustrates how to access the IColorConditionValue objects from the criteria list and change the properties FormatColorRGB, Type and Value by accessing each criterio from the Criteria list.
