Remarks

The Microsoft.Office.Tools.Excel.Controls.ComboBox is different from a System.Windows.Forms.ComboBox. The Microsoft.Office.Tools.Excel.Controls.ComboBox has additional members that enable it to be added to an Excel worksheet and that give it additional methods and properties.

Do not use the New constructor to create a new ComboBox. Use the AddComboBox() method to add a new ComboBox to a worksheet.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
