このメンバーの使用例を次のコード例に示します。The following code example demonstrates the use of this member. この例では、イベントハンドラーがDataGridView.RowPrePaintイベントの発生を報告します。In the example, an event handler reports on the occurrence of the DataGridView.RowPrePaint event. このレポートは、イベントがいつ発生し、デバッグに役立つかを理解するのに役立ちます。This report helps you to learn when the event occurs and can assist you in debugging.

コード例を実行するには、という名前DataGridView DataGridView1の型のインスタンスを含むプロジェクトに貼り付けます。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 次に、イベントハンドラーがDataGridView.RowPrePaintイベントに関連付けられていることを確認します。Then ensure that the event handler is associated with the DataGridView.RowPrePaint event.

private void DataGridView1_RowPrePaint(Object sender, DataGridViewRowPrePaintEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ClipBounds", e.ClipBounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "InheritedRowStyle", e.InheritedRowStyle );

messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowPrePaint Event" );
}
