moving data in listbox

[Signo.X]

hello all ,

Ive got 2 list boxes, one is bind to a DB column , i.e. it reads data from column in an access db table.

the other list box i use to move selected items from the first list box.
example :

list_box1 list_box2
1 2
3

> >>

i have a button > to move one record at the time and >> to move all the records from box1 to list 2 at one hit.

i use the following when the user clicks on > :
ListBox2.Items.Add(ListBox2.Text)
it works fine , but then how do i remove the value from list_box1 so its only in list_box2?

when i try list_box1.items.removeat(index) it gives me an error :
Cannot modify the Items collection when the DataSource property is set

how can i remove it without any problems ??????

also , when the user clicks on >> , how do i copy all the items in list1 to list2???

I'm getting sick of this , i spend almost 4 hours trying different things to fix that problem...

please help!!

If control is databound you have to modify its datasource, else you can choose to not bind it to datasource but instead add all the items manually from datasource and treat everything manually.

Don't attach a datasource to your listbox.
You will have to add the items manually to your listbox

For each item in datatable
lstbox1.items.add(item)
Next

lstbox1.displaymember = ...
lstbox1.valuemember = ...

Now you should be able to do whatever you want with them, and at the end you can save all items of lstbox2.
