    ByVal Hook As Object _

public int OnPopup (
    object Hook

);

Hook [in]

  Hook is a parameter of type IDispatch

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

hook is a reference to an IApplication object.

Remarks

The OnPopup method occurs just before the menu containing the MultiItem is displayed. OnPopup provides a hook to the application object that instantiated the MultiItem and is also used to set the number of items in the MultiItem.

When implementing IMultiItem to create a custom multiItem, use the OnPopup method to get a hook to the application. Also, write code to determine how many items will make up this multiItem and return that number using IMultiItem_OnPopup.
