名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)
構文
'宣言
Public ReadOnly Property RowCount As Integer
'使用
Dim instance As TabControl
Dim value As Integer
value = instance.RowCount
public int RowCount { get; }
public:
property int RowCount {
int get ();
}
/** @property */
public int get_RowCount ()
public function get RowCount () : int
プロパティ値
タブ ストリップに現在表示されている行の数。

Multiline プロパティが true の場合、タブが表示されている行の数を確認するには、RowCount プロパティを使用します。
使用例
5 つの TabPage オブジェクトのある TabControl を作成するコード例を次に示します。この例では、RowCount プロパティを使用して、tabControl1 タブ ストリップ内の現在の行数を取得します。
この例では、System.Drawing 名前空間と System.Windows.Forms 名前空間を使用します。
