well i can delete the current row using Delete method, but how can i add it back to list at different index.
for eg if the user has selected the first item in the list and press down button, it should delete the row at index 0 and insert it back into the list at index 1.
Maybe the better question is, why do you want to move items
I had a app I have been working on where I had one list box with column names and another on the right hand side and inbetween the two I had arrows (one pointing left, one pointing right) and the user would select a column and hit the arrow and it would move the column to the right list box.
Now for the right list box I just redid a new DataRow then set the column name and added it to the datasource of the right hand listbox.
For the left hand listbox I had the datasource set to a DataView and I just filtered out the column. DV.rowfilter = "ColumnName <> 'mychossenColumn'" I would keep adding to the filter for each column I moved. I would delete from the filter for each column I put back to the lefthand listbox.
Hope this helps. Sometimes is good to explain what you are wanting to happen so that others can provide different ways of doing the goal. After all there is always more then one way to skin a cat.

You will have to do it via the currencymanager's List property (insert) or rebind the listbox.
Dim CM as currencymanager = ctype(me.bindingcontext(listbox.datasource),currencymanager)
'dr is new datarow
cm.list.insert(0,dr)
damned

for x as int16 to cm.count -1
cm.position = x
Dim DRV as datarowview = ctype(cm.current,datarowview)
if drv.item("ColumnName") = "" then 'a way to check the a column
drv.delete()
end if
next
Hope this helps
