このプロパティは、DataGridView の外側の境界線に影響します。セル境界線のスタイルを設定するには、CellBorderStyle プロパティを使用します。

使用例

単純なデータバインド DataGridView を初期化する方法を次のコード例に示します。この例では、BorderStyle プロパティの設定方法も示します。この例を実行するには、dataGridView1 という名前の DataGridView を含むフォームに次のコードを貼り付け、コードで指定された connectionString 変数の値を、例が実行されるシステムに対して有効な文字列に置換して、フォームのコンストラクタまたは Load イベントハンドラから InitializeDataGridView メソッドを呼び出します。

Visual Basic

Private Sub InitializeDataGridView()
    Try
        ' Set up the DataGridView.
        With Me.dataGridView1
            ' Automatically generate the DataGridView columns.
            .AutoGenerateColumns = True

            ' Set up the data source.
            bindingSource1.DataSource = GetData("Select * From
 Products")
            .DataSource = bindingSource1

            ' Automatically resize the visible rows.
            .AutoSizeRowsMode = _
                DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders

            ' Set the DataGridView control's border.
            .BorderStyle = BorderStyle.Fixed3D

            ' Put the cells in edit mode when user enters them.
