Data Controls In ASP.NET


Both DataList and DetailsView are Data Controls, means both are used to Display and Manipulate Data.

Note: The Controls having DataSource Property are called Data Controls in ASP.NET.

Data List:

  • DataList is an Unformatted Data Control like repeater control in ASP.NET.
  • DataList Controls are used to display a list of Items.
  • The DataList control is useful for displaying data in any repeating structure.
  • Eval() and Bind() can be used to bind data in DataList.

The following Templates can be used to display the Structure of DataList:


Details View

  • DetailsView is a formatted data control like GridView Control in ASP.NET.
  • The DetailsView control displays only a single data record at a time, even if its data source exposes multiple records.
  • CRUD operations are possible in DetailsView.
  • asp:BoundField is used to bind data in DetailsView.

The following are the some important templates of DetailsView Control:
