remove highlighting from datagrid row

[Robert Smith]

Hello,
I have a problem whereby I wish to programmaticlly change the current row
of the datagrid to a specific row. This is so that when the user clicks on a
grid row
and the datavalidation fails then the cursor and highlight should move back
to the
original cell.
The code I have so far is as such
Dim IntLastRow as integer

Private sub
MyDatagrid_currentcellchanged(.................... ..................etc)
dim IntCurrrow as integer = mydatagrid.currentcell.rownumber

If IntLastRow = 0 then
IntLastRow = IntCurrRow
end if
If Not DataValidation(IntLastRow) then
'un-select the clicked row
MyDatagrid.Unselect(IntCurrRow)
'Move back to the row b4 the event
MyDataGrid.CurrentIndex = IntLastRow
MyDataGrid.select(IntLastRow)
end if

IntLastRow = MyDataGrid.currentIndex

end sub

This seems to correctly place a cursor next to the original row b4 the
click, however
the clicked row still has a highlight on it. How do I remove this hightlight
and
possibly put it on another row.
Thanx in advance
Robert
