MaxValue Property (UltraCurrencyEditor)

Gets/sets the control's maximum allowable value.
Syntax
'Declaration
 
Public Property MaxValue As Decimal
public decimal MaxValue {get; set;}
Remarks

The UltraCurrencyEditor control provides the ability to restrict the range of values that will be accepted by the control. This is accomplished by setting the MinValue and MaxValue properties.

When the control loses focus with a value that is outside the range determined but the MinValue and MaxValue properties, the UltraNumericEditorBase.ValidationError event is raised.

Example
This sample shows how to set the Min/Max value properties and also how to handle when a value is entered that exceeds the aforementioned boundaries by using the ValidationError event.

 End Sub

 Private Sub UltraCurrencyEditor1_ValidationError(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinEditors.ValidationErrorEventArgs) Handles UltraCurrencyEditor1.ValidationError
