Public Property MinValue As Decimal

C#

public decimal MinValue {get; set;}

解説

UltraCurrencyEditor コントロールは、コントロールによって認められる値の範囲を制限する機能を提供します。これは、MaxValue プロパティとMinValueプロパティを設定することによって行います。

MinValue および MaxValue プロパティで決定された範囲外にある値でコントロールがフォーカスを失うと、UltraNumericEditorBase.ValidationError イベントが発生します。
