Hello Mario,
Question 2:

How do I keep the row I have selected and not the current Index ????

I see two approaches to this.

The first one is to remember the row's unique key when the grid is
re-sorted, then look up the remembered key and determine the new row number
for this row (of course the look up should be performed in the dataview
obtained through CurrencyManager.List property and not in the bound data
table).

The second approach is to subscribe to the DataView's ListChanged event and
react on ItemMoved events (but I am not sure they are raised when sort order
changes - they are raised for sure when a row changes its place in the view
after a value has been changed in a column the view is sorted by.)
