範例

下列程式碼範例示範此成員的使用。 在此範例中,事件處理常式會報告事件發生次數 PropertyGrid.SelectedGridItemChanged 。 此報告可協助您瞭解事件發生的時間,並可協助您進行偵錯。 若要報告多個事件或經常發生的事件,請考慮將 取代 MessageBox.ShowConsole.WriteLine 為 或將訊息附加至多行 TextBox

若要執行範例程式碼,請將它貼到包含名為 PropertyGrid1 之型 PropertyGrid 別實例的專案。 然後,確定事件處理常式與事件相關聯 PropertyGrid.SelectedGridItemChanged

private void PropertyGrid1_SelectedGridItemChanged(Object sender, SelectedGridItemChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "NewSelection", e.NewSelection );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OldSelection", e.OldSelection );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "SelectedGridItemChanged Event" );
}
Private Sub PropertyGrid1_SelectedGridItemChanged(sender as Object, e as SelectedGridItemChangedEventArgs) _ 
     Handles PropertyGrid1.SelectedGridItemChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "NewSelection", e.NewSelection)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OldSelection", e.OldSelection)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"SelectedGridItemChanged Event")

End Sub
