e As EntityDataSourceChangingEventArgs) Handles EntityDataSource1.Inserting
Dim myPhotoAlbum As PhotoAlbum = CType(e.Entity, PhotoAlbum)
myPhotoAlbum.UserName = User.Identity.Name
End Sub
C#
protected void EntityDataSource1_Inserting(object sender,
EntityDataSourceChangingEventArgs e)
{
PhotoAlbum myPhotoAlbum = (PhotoAlbum)e.Entity;
myPhotoAlbum.UserName = User.Identity.Name;
}
