What's difference between Datagrid, Datalist and repeater?
The Datalist ,Datagrid, and Repeater are all ASP.NET data Web controls.
They have many things in common such as DataBind Method ItemDataBound and DataSource Property, ItemCreated.
Whenever you assign the DataSource Property of a Datagrid to a DataSet then each DataRow present in the DataRow Collection of DataTable is given to a corresponding DataGridItem & this is same for the rest of the two controls also. As The HTML code generated for a Datagrid has an HTML TABLE element created for the particular DataRow & it is a Table form representation with Columns and Rows.
For the Datalist its an Array of Rows and based on the Template Selection and the RepeatColumn Property value We can specify how many DataSource records must appear per HTML
For the Repeater Control, the Datarecords to be displayed totally depends upon the Templates specified and the only HTML generated is the due to the Templates.
Addition to these, Datagrid has a in-built support for Filter , Sort and paging the Data, which is not possible when using a DataList and for a Repeater Control we would require to write an explicit code to do paging.
