IsValid メソッド (RichTextCellType)

Visual Basic
C#

'Declaration
 
Public Overrides Function IsValid( _
   ByVal o As Object _
) As Boolean

'使用法
 
Dim instance As RichTextCellType
Dim o As Object
Dim value As Boolean
 
value = instance.IsValid(o)

public override bool IsValid( 
   object o
)

パラメータ

o: 入力内容を含むオブジェクト。

戻り値の型

入力値が有効な場合はTrue、それ以外の場合はFalse

次のサンプルコードは、日付時刻値が書式設定された数値セル型でIsValidメソッドを使用する方法を示していますが、他のセル型でも同じように使用できます。

C#
Visual Basic

FarPoint.Win.Spread.CellType.DateTimeCellType dt = new FarPoint.Win.Spread.CellType.DateTimeCellType();
bool b;
dt.DateTimeFormat = FarPoint.Win.Spread.CellType.DateTimeFormat.ShortDate;
dt.MaximumDate = new System.DateTime(2010, 12, 31);
dt.MinimumDate = new System.DateTime(1990, 1, 1);
fpSpread1.ActiveSheet.Cells[0, 0].CellType = dt;
fpSpread1.ActiveSheet.Cells[0, 0].Value = new System.DateTime(2011, 9, 12);
fpSpread1.ActiveSheet.Cells[1, 0].CellType = dt;
fpSpread1.ActiveSheet.Cells[1, 0].Value = new System.DateTime(1989, 9, 12);
b = dt.IsValid(fpSpread1.ActiveSheet.Cells[0, 0].Value);
listBox1.Items.Add(b.ToString());

Dim dt As New FarPoint.Win.Spread.CellType.DateTimeCellType()
Dim b As Boolean
dt.DateTimeFormat = FarPoint.Win.Spread.CellType.DateTimeFormat.ShortDate
dt.MaximumDate = New System.DateTime(2010, 12, 31)
dt.MinimumDate = New System.DateTime(1990, 1, 1)
FpSpread1.ActiveSheet.Cells(0, 0).CellType = dt
FpSpread1.ActiveSheet.Cells(0, 0).Value = New System.DateTime(2011, 9, 12)
FpSpread1.ActiveSheet.Cells(1, 0).CellType = dt
FpSpread1.ActiveSheet.Cells(1, 0).Value = New System.DateTime(1989, 9, 12)
b = dt.IsValid(FpSpread1.ActiveSheet.Cells(0, 0).Value)
ListBox1.Items.Add(b.ToString())
