Hi guys,
I got 2 listboxes in a window form, one on left and one on right. The
1st listbox have some items while the 2nd listbox is empty. Also there
are 2 buttons between the 2 listboxes which used to move item from/to
the 1st and 2nd listbox
My problem here is that after I bind the data to the 1st listbox (from
a dataTable, using DisplayMember and ValueMember), and I try to move 1
of the item from this 1st listbox to the 2nd listbox by:
If ListBox1.Select edIndex <-1 Then
ListBox2.Items. Add(ListBox1.Se lectedItem)
ListBox1.Items. Remove(ListBox1 .SelectedItem)
End If
Item can be add to the 2nd listbox but the displayText of it becoming:
System.Data.Dat aRowView
Anyone can help? Thanks!! :) 3 5759
Perry,
The listbox has two methods to show items, one by using his own collection,
second by showing it from the underlying bounded collection.
They can not mix up while the second method has priority. Do you want to
achieve what you want, than you have or all the items first to set in the
listbox items and not bind or you have to move the rows in your datatables.
If it is about one datatable, than you can just add a column which tells in
what listbox it has to be.

Thanks for your reply Cor :)
Yea, I just got one datatable, Would you please tell me the way to
bind the data from a dataTable (which got 2 column: ID and Name. In
this case, the displaymember will be Name for Listbox1, Value will be
ID) ?
Many Thanks

Perry,
Written here so watch typos
dim myFilterColumn as dataColumn(filt er)
myDataTable.Col umns.Add("myFil terColumn")
dim myDataView as new DataView(myData Table)
dim myDataView2 as new DataView(myData Table)
myDataView1.Row Filter = "myFilterCo lumn = 1"
myDataView1.Row Filter = "myFilterCo lumn = 2"
myDataView1(3). "myFilterColumn " = "1"
etc.
myListBox1.data source = myDataView1
myListBox2.data source = myDataView1
In this situation only the second name will be displayed in listbox1

I'm having trouble figuring out how to move a list from one listbox to
another using a command button. The idea is to click on a command
button and all items in listbox A will move over to listbox B. I'm
able to move one item using AddItem, but I don't know how to move the
whole list.
Thank you.
