範例

下列程式碼範例示範如何使用這個成員。 在此範例中，事件處理常式會報告事件的發生次數 ListView.DrawSubItem 。 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。

若要執行範例程式碼，請將它貼入包含名為 ListView1 之類型 ListView 實例的專案。 然後，確定事件處理常式與 事件相關聯 ListView.DrawSubItem 。

private void ListView1_DrawSubItem(Object sender, DrawListViewSubItemEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "DrawDefault", e.DrawDefault );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Bounds", e.Bounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SubItem", e.SubItem );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ItemIndex", e.ItemIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Header", e.Header );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ItemState", e.ItemState );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "DrawSubItem Event" );
}

Private Sub ListView1_DrawSubItem(sender as Object, e as DrawListViewSubItemEventArgs) _ 
     Handles ListView1.DrawSubItem

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "DrawDefault", e.DrawDefault)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Bounds", e.Bounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SubItem", e.SubItem)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ItemIndex", e.ItemIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Header", e.Header)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ItemState", e.ItemState)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"DrawSubItem Event")

End Sub
