DataGridViewCellStyle.Format プロパティ
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim instance As DataGridViewCellStyle Dim value As String value = instance.Format instance.Format = value
セル値の書式を示す文字列。既定値は Empty です。


Last Fixed という列の DefaultCellStyle プロパティに Format プロパティを設定することにより、列の日付の書式を "Month, year" に設定するコード例を次に示します。このコード例は、DataGridViewCellStyle クラスのトピックで取り上げているコード例の一部分です。
