屬性值

在控制項集合內的控制項之索引值 (在其容器內)。 容器內的控制項會包含在定位順序中。

範例

下列程式碼範例會將 新增 Button 至表單，並設定其一些通用屬性。 此範例會將按鈕錨定在表單的右下角，讓它在表單調整大小時保持其相對位置。 接下來，它會設定 BackgroundImage 按鈕的大小，並將按鈕大小調整為與 Image 相同的大小。 然後範例會將 TabStop 設定為 true ，並設定 TabIndex 屬性。 最後，它會新增事件處理常式來處理 Click 按鈕的事件。 此範例需要您有 ImageList 名為 imageList1 的 。

備註

索引標籤索引可以包含任何大於或等於零的有效整數，在製表順序中稍早的數位。 如果相同父控制項上的多個控制項具有相同的索引標籤索引，控制項的 Z 順序會決定要迴圈執行控制項的順序。

若要讓控制項包含在定位順序中，其 TabStop 屬性必須設定為 true 。
