Office.Binding interface - Office Add-ins

Represents a binding to a section of the document. The Binding object exposes the functionality possessed by all bindings regardless of type. The Binding object is never called directly. It is the abstract parent class of the objects that represent each type of binding: Office.MatrixBinding, Office.TableBinding, or Office.TextBinding. All three of these objects inherit the getDataAsync and setDataAsync methods from the Binding object that enable to you interact with the data in the binding. They also inherit the ID and type properties for querying those property values. Additionally, the MatrixBinding and TableBinding objects expose additional methods for matrix- and table-specific features, such as counting the number of rows and columns.
