Button.ZOrder Property

  • 發行項

Gets the z-order position of the Button.

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 ReadOnly Property ZOrder As Integer

public int ZOrder { get; }

Property Value

Type: System.Int32
The z-order position of the Button.

Remarks

The z-order is determined by the OLEObjects collection.

In any collection of objects, the object at the back of the z-order is collection(1), and the object at the front of the z-order is collection(collection.Count).

Examples

The following code example uses the ZOrder property to set the z-order of three Button controls on a worksheet. If the button currently at the front of the z-order is clicked, then the button is moved to the back of the collection. Otherwise, the button is moved to the front of the collection. Note that the z-order of the three buttons initially range from 2 to 4. The Runtime Storage Control on the worksheet initially has the z-order position of 1.

This example is for a document-level customization.
