Value property specifies the value of the named reference. When this reference is referred in formulas of other objects, this value will be used in those formula calculations. Note that this property cannot be specified if Formula property is specified. If Formula property is set, this property will return the result of the formula calculation. Furthermore attempting to set this property when Formula property is set will result in an exception.
Note: When Formula is set, it may get calculated asynchronously by the XamCalculationManager and therefore the result of the formula calculation may not be available right away.
