Grid Control - Javabean Example

This is another example where a Collection of Javabeans can be used as the source of data for the grid. We get the list of messages from a custom MessageManager class. The messages are retrieved and placed into an ArrayList. From there, the ArrayList is passed to the grid via the datasrc attribute.

The columns of the grid can be bound to the properties of the Javabean. This is done using the datafield attribute on the various column tags. The value of the datafield attribute must correspond with a getter method for the underlying Javabean.
e.g.     <dotj:datacolumn datafield="userid" ... />    ---->    Message.getUserid()
Retrieving data took 31 ms.
Note: Click on a column header to sort the grid!
