protected void LoadExercises(object sender, EventArgs e)
   {
       // Navn, (Beskrivelse), Type, Exid, Target
       var exercises = from ex in context.Exercises
                       select new {exerciseId = ex.ExerciseId,
exerciseName = ex.Name, exerciseType = ex.ExerciseType.Name,
exerciseTarget = ex.Targets.First<Target>().Muscle.Name };
       ExercisesGridView.DataSource = exercises;
       ExercisesGridView.DataBind();

   }

I'm using the code above to fill a gridview. but how do I prevent it
from showing exerciseId while still being able to use it?
Furthere more how do I enable selection?

best regards,
taa
