JSF datagrid component

[vijaya vemula]

Hi iam using datagrid component of JSF to display a dynamic table.
Dynamic table has a set ofrecords displayed from the database by specifying datasource attribute of grid.

out of all the columns one column (clientID) is displayed as commandLink which upon clicking has to display its corresponding values into the form displayed just above my datagrid.

My question is how to populate the datagrid values into the form inputText fields when the user clicks on commandLink in datagrid.

Any help will be greatly appreciated.
