  Jan 12, 2011 10:35 AM|LINK

  If I try to implement, inherit StateManagedCollection i lost Temalated content after few changes(action over collection adding or reordering) templated contend disappear and show only Name of Item. This is second try for implementation:

  
  

  [AspNetHostingPermission(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal), AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)] public class TabsCollection : StateManagedCollection { private static readonly Type[] knownTypes;
  
  
      static TabsCollection()
      {
          TabsCollection.knownTypes = new Type[] { typeof(Item) };
      }
  
  
      public Item this[int index]
      {
          get
          {
              if (this.Count < index)
              {
                  return null;
              }
              return (Item)((IList)this)[index];
          }
          set
          {
              ((IList)this)[index] = value;
          }
      }
  
  
      public int Add(Item value)
      {
          return ((IList)this).Add(value);
      }
  
  
      public int IndexOf(Tab value)
      {
          return ((IList)this).IndexOf(value);
      }
  
  
      public void Insert(int index, Item value)
      {
          ((IList)this).Insert(index, value);
      }
  
  
      public void CopyTo(Tab[] toolBarSetArray, int index)
      {
          base.CopyTo(toolBarSetArray, index);
      }
  
  
      protected override object CreateKnownType(int index)
      {
          return new Tab();
      }
  
  
      protected override Type[] GetKnownTypes()
      {
          return TabsCollection.knownTypes;
      }
  
  
      public void Remove(Item value)
      {
          ((IList)this).Remove(value);
      }
  
  
      public void RemoveAt(int index)
      {
          ((IList)this).RemoveAt(index);
      }
  
  
      public bool Contains(Item value)
      {
  
  
          return ((IList)this).Contains(value);
      }
  
  
      protected override void OnValidate(Object value)
      {
          if (value.GetType() != typeof(Item))
              throw new ArgumentException("value must be of type Item.", "value");
      }
  
  
      protected override void SetDirtyObject(object o)
      {
          if (o is Item)
          {
              ((Item)o).SetDirty();
          }
      }
  }
