My ultraganttview is bound to a datatable via ultracalenderinfo.setdatabindingfortask.

I fill the DataTable like this:

theTasks.Rows.Add( ...)

AddHandler theTasks.RowChanged, AddressOf handleRowChanged

How can i change the order of the tasks (e.g. via drag and drop)? And how do i get the information about the position in my handleRowChanged?
