Button.Left 屬性

取得或設定 Button 的左邊緣和工作表的左邊緣之間的距離 (以點為單位)。

命名空間:  Microsoft.Office.Tools.Excel.Controls
組件:  Microsoft.Office.Tools.Excel.v4.0.Utilities (在 Microsoft.Office.Tools.Excel.v4.0.Utilities.dll 中)

語法

'宣告
Public Property Left As Double
public double Left { get; set; }

屬性值

型別:System.Double
Button 的左邊緣和工作表的左邊緣之間的距離 (以點為單位)。

備註

Button.Left 屬性使用點,而 Control.Left 屬性則使用像素。

將這個值設定為負數或是大於 12288 的數字時,並不會擲回例外狀況,但控制項還是會設定在 0 和 12288 之間。

範例

下列程式碼範例會比較工作表中兩個 Button 控制項的調整大小和重新定位行為。 第一個按鈕的 Click 事件處理常式會調整按鈕的 HeightWidth 屬性,使得按鈕得以變更大小,但仍位於工作表的相同位置上。 第二個按鈕的 Click 事件處理常式會調整按鈕的 Top 和 Left 屬性,使按鈕可以變更在工作表上的位置,但仍維持同樣的大小。

這是示範文件層級自訂的範例。
