Button.Left Property

  • 아티클

Gets or sets the distance, in points, between the left edge of the Button and the left edge of the worksheet.

Namespace:  Microsoft.Office.Tools.Excel.Controls
Assembly:  Microsoft.Office.Tools.Excel.v4.0.Utilities (in Microsoft.Office.Tools.Excel.v4.0.Utilities.dll)

Syntax

'Declaration
Public Property Left As Double

public double Left { get; set; }

Property Value

Type: System.Double
The distance, in points, between the left edge of the Button and the left edge of the worksheet.

Remarks

The Button.Left property uses points, whereas Control.Left property uses pixels.

Setting the value to a negative number or a number higher than 12288 does not throw an exception but results in the control being set between 0 and 12288.

Examples

The following code example compares the resizing and relocating behavior of two Button controls to a worksheet. The Click event handler of the first button adjusts the Height and Width properties of the button so that the button changes size, but remains in the same location on the worksheet. The Click event handler of the second button adjusts the Top and Left properties of the button so that the button changes location on the worksheet, but stays in the same size.

This example is for a document-level customization.
