Hello,\
\
To obtain an old cell's value, call the GridView.GetRowCellValue method in the GridView.CellValueChanging event handler:\
\
[C#]Open in popup window\
void gridView1_CellValueChanging(object sender, CellValueChangedEventArgs e) {\
object value = gridView1.GetRowCellValue(e.RowHandle, e.Column);\
}\
\
[VB.NET]Open in popup window\
Private Sub gridView1_CellValueChanging(ByVal sender As Object, ByVal e As CellValueChangedEventArgs)\
Object value v = gridView1.GetRowCellValue(e.RowHandle, e.Column)\
End Sub\
\
A new value is available in the e.Value parameter.\
\
Let me know if this solution meets your requirements.
