PowerTools SPREAD for ASP.NET 8.0J
Parse メソッド (ComboBoxCellType)

解析対象の、シートのセルの文字列
この型に基づいてセル型を派生させるときに、このメソッドをオーバーライドすると、 シートのセルから解析され、データモデルに入力される内容が変化します。
構文
'Declaration
 
Public Overrides Function Parse( _
   ByVal s As String _
) As Object
public override object Parse( 
   string s
)

パラメータ

s
解析対象の、シートのセルの文字列

戻り値の型

データモデルにobjectとして設定する解析結果
以下の例では、ComboBoxCellTypeをサブクラス化し、スプレッドシートの先頭セルにコンボボックス型セルを作成します。コンボボックスを表示するには、先頭セルをダブルクリックします。
