  Requirements
  RadControls for WinForms	Q2 2010
  .NET version	Any
  Visual Studio version	Any
  programming language	C# and VB.NET

  
  PROJECT DESCRIPTION 
  I put together this little function for something that wasn't required in the end but thought it could be quite useful sometimes. 
  
  This code returns a collection of RadMenuItemBase objects from a given control that contains RadMenuItemBase objects 
  
  For example: Use it to get back a collection of all RadMenuItemBase objects in RadMenu, RadApplicationMenu, RadSplitButton 
  VB:
  

  Public Shared Function GetRadMenuItems(ByVal items As Telerik.WinControls.RadItemCollection) As ReadOnlyCollection(Of RadMenuItemBase)

      Dim returnItems As New List(Of RadMenuItemBase)()

      For Each item As RadMenuItemBase In items

          returnItems.Add(item)

          Dim subItems As ReadOnlyCollection(Of RadMenuItemBase) = GetRadMenuItems(item.Items)

          returnItems.AddRange(subItems)

      Next

      Dim readOnlyItems As New ReadOnlyCollection(Of RadMenuItemBase)(returnItems)

      Return readOnlyItems

  End Function

  C#: 
  

  public static ReadOnlyCollection<RadMenuItemBase> GetRadMenuItems(Telerik.WinControls.RadItemCollection items)

  {

      List<RadMenuItemBase> returnItems = new List<RadMenuItemBase>();

      foreach (RadMenuItemBase item in items) {

          returnItems.Add(item);

          ReadOnlyCollection<RadMenuItemBase> subItems = GetRadMenuItems(item.Items);

          returnItems.AddRange(subItems);

      }

      ReadOnlyCollection<RadMenuItemBase> readOnlyItems = new ReadOnlyCollection<RadMenuItemBase>(returnItems);

      return readOnlyItems;

  }

  
  The code can easily be adapted too to get back a flattened collection of items from other types,
  For example: Adapt it and use it to get back a collection of RadtreeNode objects in a RadTreeView
  VB:
  

  Public Shared Function GetRadTreeNodes(ByVal nodes As Telerik.WinControls.UI.RadTreeNodeCollection) As ReadOnlyCollection(Of RadTreeNode)

      Dim returnNodes As New List(Of RadTreeNode)()

      For Each node As RadTreeNode In nodes

          returnNodes.Add(node)

          Dim subNodes As ReadOnlyCollection(Of RadTreeNode) = GetRadTreeNodes(node.Nodes)

          returnNodes.AddRange(subNodes)

      Next

      Dim readOnlyNodes As New ReadOnlyCollection(Of RadTreeNode)(returnNodes)

      Return readOnlyNodes

  End Function

  C#:
  

  public static ReadOnlyCollection<RadTreeNode> GetRadTreeNodes(Telerik.WinControls.UI.RadTreeNodeCollection nodes)

  {

      List<RadTreeNode> returnNodes = new List<RadTreeNode>();

      foreach (RadTreeNode node in nodes) {

          returnNodes.Add(node);

          ReadOnlyCollection<RadTreeNode> subNodes = GetRadTreeNodes(node.Nodes);

          returnNodes.AddRange(subNodes);

      }

      ReadOnlyCollection<RadTreeNode> readOnlyNodes = new ReadOnlyCollection<RadTreeNode>(returnNodes);

      return readOnlyNodes;

  }
