I have some tables that have ownerships as shown below.

Contracts
Sections
Heading memo
Items memo
Subitems memo
Ratebands

Contracts have sections, sections have items etc

I thinking about using a treeview control to display this data instead of the presentlty used series of grids . The user would be able to click into part of the treeview to indicate the level at which he would like to edit or insert data.

Since much of the data that need to be displayed is in memo fields of a few lines in lenghth I need a control that can display expanded memo fileds tidily.

The control would have to be quick and robust since it would form the basis of the application, which is for the editing and creation of works schedules.

Do folks have any idea which controls I shopuld look at first.
