Hi,

I have a list<hotel> ,which i'm binding to a listview, This list contain columns with values and null values. I'm doing sorting in both ascending and descending order. Descending no problem it works

lstHotels.DataSource = lstHotelList.OrderByDescending(o => o.MinPrice).ToList();

in Ascending order

lstHotels.DataSource = lstHotelList.OrderBy(o => o.MinPrice).ToList();

in this case the rows that have null values are appearing on the top,
What I want is I want to show records with smaller value on the top and put the records with null values at the end of listview

how to do?
ANy help wil be appreciated
