I am trying to make a control similar to the ones used in .NET in the DataGrid Property builder. There is a listbox on the left and a listbox on the right with two arrows in the middle to move things between lists.
Both listboxes are being populated by databases. The one on the left holds all non-selected items, the one on the right shows the items that have been selected.
I need to move items between the boxes and then write items on the right to a database when the user clicks the save button...
