The Eval method evaluates late-bound data expressions in the templates of data-bound controls such as the GridView, DetailsView, and FormView controls and the Bind method is typically used with input controls such as the TextBox control rendered by a GridView row in edit mode.

Have you searched for the answer before asking?

Eval is a protected method defined on the TemplateControl class, from which the Page class is derived. Bind is a new ASP.NET 2.0 databinding keyword. It's not a method of any specific class.

Eval is used for unidirectional (readonly) data binding, while Bind is for bi-directional (editable) databinding.
