ListView In .NET

Basically, it's a control for displaying data from a datasource using one or more templates which you define yourself.

It's similar to but more flexible than a GridView which only allows the data to be displayed in strict tabular form (i.e. rows and columns).

For more details, I'd check out the MSDN documentation:
