Hi,
>From what I understand of ur code posted before, u want to physically
move the data one index above or below in the dataprovider array and
display it on the datagrid. If this is correct then ur code looks
fine, but there is one problem.
U have handled the boundary condition for Move Up functionality namely
selectedIndex = -1 or selectedIndex = 0 but the same is not the
boundary condition for Move Down. Here u have to check for
selectedIndex = -1 (Unseleted row) & selectedIndex =
dg.dataprovider.length (Last row selected).
(If I select the first row in the datagrid which is equivalent to
selectedIndex = 0 then I should be able to move it down.)
Also in case of the logic used for Move Down, u should drop the node
first & then add the node at the next position to get the desired
effect. My understanding of addItemAt is that every element equal to
or greater then the index to be added at gets shifted one ahead. (If
this is not the case then ur code is fine. Please let me know that I
had it understood wrong)
Hope this helps.
