You can configure the List Edit control to be started from a toolbar. The ListEdit toolbar 
has been configured to use the method ListEditToolbar. This method uses the client API called ListEditToolbar.
When it is started from a toolbar, the List Edit control contains the contents of the active list view window. All objects in the list view window must have a common interface. In most cases, this means that the objects must be of the same type. If there is no list view window active when you click the List Edit toolbar button, you will be prompted to select a list view. If the objects the list view contains do not have a common interface, the List Edit control does not open.
When there are multiple list editing methods configured for the same interface, the user must choose which list to edit with the List Edit control. An example of this situation is one method or list that uses the save as list document functionality, and one that does not. The different configurations are presented to the user in the form of a list of the multiple List Edit controls.
The list is composed of the Display As (SPFGUIDisplayAs) properties of the available methods.
