Parameters
- listObject
Type: Microsoft.Office.Interop.Excel.ListObject
The native list object to test. Do not supply this parameter yourself. When you call this method on an Excel list object, the runtime supplies this parameter.
- factory
Type: Microsoft.Office.Tools.Excel.Factory
An object that provides access to certain features in your document-level customization. Pass the Globals.Factory object to this parameter.
Return Value
Type: System.Boolean
true if a Microsoft.Office.Tools.Excel.ListObject host control has been created for the current Microsoft.Office.Interop.Excel.ListObject object; otherwise, false.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type ListObject. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks
In a document-level customization, this method returns true only if the Microsoft.Office.Interop.Excel.ListObject object on which you call this method is the underlying object of a Microsoft.Office.Tools.Excel.ListObject host control in the current customization. Otherwise, this method returns false.
This method is provided for backward compatibility with Office projects that you retarget from the .NET Framework 3.5 to the .NET Framework 4. In new projects that target the .NET Framework 4, you should call the HasVstoObject method that is provided by the Globals.Factory object in your project. For more information, see Getting Extended Objects from Native Office Objects in Document-Level Customizations.
