Question

I’m customize the fields displayed in the Pages document library (the table displayed clicking site actions->all site content->pages).

It was suggested by someone who knows more about sharepoint than me that I should perhaps remove the fields which I didn’t want from the default view programmatically on the activation of a feature, so I’ve written this code which feels like a very unelegant solution, and also does not work.

SPWeb web = properties.Feature.Parent as SPWeb;          if (web != null)         {             SPList list = web.Lists['Pages'] as SPList;             if (list != null)             {                 foreach (SPField field in list.Fields)                 {                     if (field.Title != 'Type' &&                         field.Title != 'Name' &&                         field.Title != 'Modified' &&                         field.Title != 'Checked Out To' &&                         field.Title != 'Page Layout')                     {                         if (list.DefaultView.ViewFields.Exists(field.InternalName))                         {                             list.DefaultView.ViewFields.Delete(field);                                                         }                     }                 }                  list.DefaultView.Update();             }         }     } 

The code definately executed on activation of the feature so I’m obviously doing something wrong. I’ve searched for a solution to this so I apologise if I’ve missed something on google or this site which is blindingly obvious.

This is because the changes to list.DefaultView.ViewFields are going out of scope. The collection is being refreshed from the database before the call to Update() is reached. Try:

if (list != null) {     SPView view = list.DefaultView;      foreach (SPField field in list.Fields)     {         if (field.Title != 'Type' &&             ...             field.Title != 'Page Layout')         {             if (view.ViewFields.Exists(field.InternalName))             {                 view.ViewFields.Delete(field);                                             }         }     }      view.Update(); }
