At design time, information about an attribute that is bound to a graphical object can be displayed in a Tool Tip when the mouse hovers over an object. The tool tip can display the following information:
Attribute name
Edit type
Length
Caption
Note: If an object, which requires an attribute, has been added to the form by dragging it from the toolbox, but the form has not yet been saved, the tooltip displays the text "Attribute not assigned." To display the tool tip for such an object, you must first save the form to create an attribute for the object.
Graphical objects that cannot be bound to an attribute display the text Static Control in the tooltip. Objects for which an attribute is optional and that have been added to the form by dragging from the Toolbox are treated as static controls and they display the same tooltip.
