I have some table with Date column. I want to have default sorting on my Date column with descending order that rows with last date wil be on the top. I have a LINQ to SQL DataSource. I have attempted to use OrderByParameters, but I can't make descending order on my column. Which the best way to resolve my problem? May be there is some way in Dynamic Data framework not in DataSource. How can I intercept creating Select command to database?

I would say you need to tell the GridView which column to sort on by default I would asume that this will be a custom DD page.

if (!IsPostBack)
    GridView1.Sort("LastName, FirstName", SortDirection.Ascending);

In the Page_Load

Hope this helps
