wpf + ef + datagrid + sorting = beurk...

Question

i have :

1 form with controls to edit a record (myrecord)

1 grid on this form to edit sub details records (myrecord.details)

it seems very very complicated to sort the datagrid according one column ???

yes, i have been searching the forum and googling around, but it seems you need to write at least 10 lines of code just to do this, and you have to use subcollections that i never heard of...

seems that EF is still is way to complicated... it helps you save 50 lines of code to link one table to a class (object) but then you loose plenty of time in all forms all around your software... doesn't look like a progress... brr...

Answer 1

Hi,

Have you tried to use an ObservableCollection ? I gave it a try using the Northwind  sample database and

   NorthwindEntities db=new NorthwindEntities();
      dg.ItemsSource = new ObservableCollection<Categories>(db.Categories);

is enough to sort on the id, name or description when I click the column.

Perhaps could you point us on one of the article you saw so that we can better understand the context in which the code you are talking about is needed.

Answer 5

I ended up encapsulating all this in a :

ObservableCollection, ListCollectionView, pretty much a lot of code for not something special... seems to work now. but it just refrain me to use more ef+wpf...

thanks anyway for the tips
