RadGrid w/ ADO.NET Entity Framework & Dispose/Using

[kpat154]

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.
