Data Binding

DATA BINDING

• Data binding allows the developer to associate a data source to a control and have that control automatically display the data
• Data binding is declarative not programmatic
• Being Declarative means that Data Binding is defined outside the code, alongside the controls in the .aspx page
• In ASP.net, most of the web controls support single value data binding
• Single value Data Binding, developer can bind a control property to a data source, but the control can display only a single value
• Data Controls support Repeated Value binding, which means they expose data source property
• Repeated Value binding fills the data only when control’s DataBind method is called
