VS Solution Explorer – Collapse All

I never knew I needed this until I saw it was a feature in a ReSharper demo.  After a quick search and I found a macro that has been around for years.  Slap to the head!  The amount of time I spend collapsing all my solution folders and this existed the whole time!

I never use macros, but even I was able to quickly get this working.

1. Open Tools->Macros->Macro Explorer (Alt-F8)
2. Right click MyMacros
3. Select New Module
4. Select default template and name to VSMacros
5. Right-click VSMacros and click New Macro
6. Copy and paste this over the opened macro file

   Imports System

   Imports EnvDTE

   Imports EnvDTE80

   Imports EnvDTE90

   Imports System.Diagnostics

   Public Module VSMacros

   Sub SolutionCollapseAll()

   ‘ Get the the Solution Explorer tree

   Dim solutionExplorer As UIHierarchy

   solutionExplorer = DTE.Windows.Item(Constants.vsext_wk_SProjectWindow).Object()

   ‘ Check if there is any open solution

   If (solutionExplorer.UIHierarchyItems.Count = 0) Then

   Return

   End If

   ‘ Get the top node (the name of the solution)

   Dim rootNode As UIHierarchyItem = solutionExplorer.UIHierarchyItems.Item(1)

   rootNode.DTE.SuppressUI = True

   ‘Find selected node

   Dim selectedNode As UIHierarchyItem = FindSelectedNode(rootNode, solutionExplorer)

   ‘ Collapse each node

   Collapse(selectedNode, solutionExplorer)

   ‘ Select the selceted node

   selectedNode.Select(vsUISelectionType.vsUISelectionTypeSelect)

   rootNode.DTE.SuppressUI = False

   End Sub

   Private Sub Collapse(ByVal item As UIHierarchyItem, ByRef solutionExplorer As UIHierarchy)

   For Each innerItem As UIHierarchyItem In item.UIHierarchyItems

   If innerItem.UIHierarchyItems.Count > 0 Then

   If innerItem.UIHierarchyItems.Expanded Then

   ‘ Re-cursive call

   Collapse(innerItem, solutionExplorer)

   End If

   ‘ Collapse

   If innerItem.UIHierarchyItems.Expanded Then

   innerItem.UIHierarchyItems.Expanded = False

   If innerItem.UIHierarchyItems.Expanded = True Then

   ‘ Bug in VS 2005

   innerItem.Select(vsUISelectionType.vsUISelectionTypeSelect)

   solutionExplorer.DoDefaultAction()

   End If

   End If

   End If

   Next

   End Sub

   Private Function FindSelectedNode(ByVal item As UIHierarchyItem, ByRef solutionExplorer As UIHierarchy) As UIHierarchyItem

   If item.IsSelected Then

   Return item

   End If

   For Each innerItem As UIHierarchyItem In item.UIHierarchyItems

   If innerItem.UIHierarchyItems.Count > 0 Then

   If innerItem.UIHierarchyItems.Expanded Then

   ‘ Re-cursive call

   Dim result As UIHierarchyItem

   result = FindSelectedNode(innerItem, solutionExplorer)

   If Not result Is Nothing Then

   Return result

   End If

   End If

   If innerItem.IsSelected Then

   Return innerItem

   End If

   End If

   Next

   Return Nothing

   End Function

   End Module

    

7. You may now execute the macro via the Macro Explorer.  Click the folder you wish to collapse (or the Solution root to collapse everything).  Right click and run the macro.  To set a shortcut continue on with the steps below…
8. Click Tools->Options->Environment->Keyboard
9. Search for your macro in the Show commands containing textbox
10. Select your macro, keep scope global, and in the assign macro keys textbox enter your preferred shortcut (I used “ALT-CTRL-\”)
11. Click ASSIGN and then OK
12. To use, select a node and then ALT-CTRL-\.  To collapse the entire solution, select the root of the solution.
