I have recently realised how folks get significantly uncomfortable and could
also loose little amount of productivity speed when navigating Solution Explorer
which is in a state of mess due to randomly expanded and collapsed Solution
Explorer items, it surely causes at least a tiny amount of lack of clarity.
The basic TreeView control or Tree control is a common windows control found
in many places in Windows OS, including Windows Explorer. The same is found in
Visual Studio’s Solution Explorer, for those who are not aware; this control
supports some keyboard shortcuts, I mean whether you are in Windows Explorer or
Visual Studio Solution Explorer you can select a node’s parent and use these
+ (plus) --> Expand
- (minus) --> Collapse
* (asterick) --> If you would like to expand recursively a particular
item's child items
But there is no shortcut to collapse recursively.
Collapse Selection in Solution Explorer extension is available
for Visual Studio 2010 that adds an icon to the Solution Explorer (shown below),
clicking which recursively collapses the child items. You can press Ctrl + Alt +
Num(-) - numeric keypad’s '-' to use it. This extension is better than the
functionality in “PowerCommand for Visual Studio 2010” extension, as explained
in the above link.
