What is the proper way to bind data to RadGrid via the ADO.NET Entity Framework?

For example, something like...

protected void radGrid_NeedDataSource( object source, GridNeedDataSourceEventArgs e ) 
    using( EntityContext c = new EntityContext() ) 
    { 
        var query = from x in context.Topics 
                    select new 
                    { 
                        field = x.foo 
                    } 
 
        radGrid.DataSource = query; 
    } 

... will fail because the context has been disposed before the grid actually evaluates the LINQ query.

Hello kpat154,

You can use EntityDataSource instead.
