View 6 RepliesIn the attached program, I have 3 listviews.
1 is Source Invoices
2 and 3 is Customers.
When I drag something from ListView1 - it stays there, and turns a different color to show it has already been assigned. It stays in the list. This is what I want. When I drag something between 2 and 3, it should delete from the source and clone to the destination. It does this when I move 1 at a time, but if I select multiples (try 5 records) it does 3 of them, then the source list gets an error:
System.NullReferenceException: Object reference not set to an instance of an object.
If I highlight all 5 items in list 2 or 3 - then select the top item as the item to drag across, it seems to work.
If I highlight all 5 items in list 2 or 3 - then select the middle item as the item to drag across, it seems to NOT work.
I have tried going from top of list to bottom. Then thought, since I am deleting rows, maybe I should start at bottom and work up. Same thing?

Public Function getEmployees() As DataTable
Dim employeeDS As New DataSet
Dim employeeDA As New SqlDataAdapter("prc_emp_list", conn)
employeeDA.Fill(employeeDS, "employees")

The data is getting populated into the combo boxes correctly and my requirement is that when I select and employee from the first combo, his corresponding role should get selected in the second combo.
