Using Event Receiver to Set Default Values for Publishing Pages

March 29 2010 17 comments

While ago I posted something very similar to this. Here

Here’s yet another solution, and way better and faster to implement.
First create web scoped feature, that adds ItemAdded event receiver to Pages library (should’t be a task). In the ItemAdded method, set the default values which are defined in the ContentType, to each field in the listItem.

public override void ItemAdded(SPItemEventProperties properties)
{
 foreach (SPField field in properties.ListItem.ContentType.Fields)
  {
  if(field.DefaultValueTyped != null)
   properties.ListItem[field.Id] =  field.DefaultValueTyped;
  }
  properties.ListItem.SystemUpdate();
}

The code loops all the fields in the current Listitems ContenType and then checks if the default value is set. If it is, it will add it to the listitem.
The default values are typed, so no casting needed.

The drawback, the page might load faster than the items are updated and you will end up with empty fields again, refreashing will help but thats notthe way to go. If using itemAdding event all properties are embty cos the listitem is not created yet. It’s possible to set the values, but then you should know what’s the contentype going to be. At leat I didnt find if from nowhere… Btw, all this is fixed in the SharePoint 2010..

    From great Android bubble games to shooters there
    is something here for everyone and many of them are free.
    Although this may seem the most logical next step beyond offering games solely online, there has so far been little interest by developers in creating Android ports.

Pese a la abundancia de referencias bibliográficas, desde la consolidación de las redes sociales, el interés por el hipertexto ha sido desplazado por otros fenómenos como la participación en comunidades online y la escritura en blogs y wikis, tal y como pone en evidencia la publicación en 2006 de dos títulos como La blogosfera hispana: pioneros de la cultura digital, a cargo José M.
