Contains control add-ins that have been registered.
To register an add-in, you include it in the Client Add-in table in Microsoft Dynamics NAV. An add-in is a Microsoft .NET Framework assembly that enables you to add custom functionality to the Microsoft Dynamics NAV Windows client. After you have registered a control add-in, you can use it on Microsoft Dynamics NAV Windows client pages. You select the control add-in from this window and add it to a field control on the page.
You can also change a control add-in in this window.
To open this window, open Page Designer, select a field, and then on the View menu, choose Properties. In the Properties window, locate the ControlAddIn property, and then choose the Up Arrow button in the Value field. For more information about how to open Page Designer, see Page Designer.
