'Declaration
 
Public Function New()

Example
This method will create a ConditionValueAppearance using a OperatorCondition and a TrueCondition and assign them to a ConditionValueAppearance. The OperatorCondition will color negative numbers red and the TrueCondition will color any remaining numbers blue.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid
 
Private  Sub button2_Click(ByVal sender As Object, ByVal e As EventArgs)
	' Create a new ConditionValueAppearance
  Dim conditionValueAppearance As ConditionValueAppearance =  New ConditionValueAppearance() 
 
  ' Create a TrueCondition that checks for negative numbers
  Dim negativeCondition As OperatorCondition =  New OperatorCondition(ConditionOperator.LessThan,0) 
 
  ' Create an appearance that sets the ForeColor to red.
  Dim negativeAppearance As Infragistics.Win.Appearance =  New Infragistics.Win.Appearance("Negative") 
  negativeAppearance.ForeColor = Color.Red
 
  ' Create a TrueCondition. The TrueCondition will always resolve to true, so it will
  ' apply to all cell in the column. However, it will not overwrite appearances properties that
  ' have already been resolved. So this condition will only apply to cells that do not
  ' match the previous condition in the list.
  Dim positiveCondition As TrueCondition =  New TrueCondition() 
 
  ' Create an appearance that sets the ForeColor to blue.
  Dim positiveAppearance As Infragistics.Win.Appearance =  New Infragistics.Win.Appearance("Positive") 
  positiveAppearance.ForeColor = Color.Blue
 
  ' Now that we have the conditions and appearances we need, add them to the 
  ' conditionValueAppearance. The conditions will be evaluated in order.
  conditionValueAppearance.Add(negativeCondition, negativeAppearance)
  conditionValueAppearance.Add(positiveCondition, positiveAppearance)
