Remarks

Use the methods and properties of the ControlCollection interface to manage controls on an Excel worksheet. For more information, see Adding Controls to Office Documents at Run Time.

You cannot create an instance of this interface in your code, because it does not have any public constructors. To get an instance of this interface in a document-level project, use the Controls property of one of the Sheetn classes in your project. To get an instance of this interface in a document-level project, use the Controls property of a Worksheet host item that you create programmatically at run time. For more information, see Extending Word Documents and Excel Workbooks in Application-Level Add-ins at Run Time.

The following table shows how to use ControlCollection members to perform some common tasks related to controls on documents.

Task

Action

Add a control to the worksheet.

Use one of the Add<control> methods. For example, to add a Microsoft.Office.Tools.Excel.ListObject, use the AddListObject method.

Remove a control from the worksheet.

Use the Remove method.

Determine whether a control is in the collection.

Pass the control or its name to the Contains method.

Get the index of a control in the collection.

Pass the control or its name to the IndexOf method.

Get a control from the collection.

Pass the index or name of the control to the Item property.
