DotNetBar for Windows Forms also includes bread-crumb style horizontal tree control CrumbBar™ in native Windows Vista style as well as Office 2007 style with Blue, Black and Silver color schemes.
Bread-crumb style navigation is very well suited for hierarchical navigation user interfaces especially where available screen real-estate is limited. CrumbBar™ consumes less space than traditional tree control by not showing all elements in tree structure. Rather it shows current selection place in hierarchy and it allows one-click navigation to first-level children or any parent item.
Here is screen-shot of CrumbBar™ control in action as shown in sample application included with DotNetBar:
To select child node user can show the popup menu with list of children nodes for selected item as shown in image below:
Selecting parent node or different child node of any parent in the tree is accomplished in the same manner as illustrated in image below:
In case where selected node is deep inside of tree hierarchy and all parent nodes cannot be displayed inside of the control due to the size constraints CrumbBar™ provides the "overflow" popup which allows easy access to all parent nodes. This functionality is shown in image below:
To edit CrumbBar™ control items/nodes in Visual Studio.NET we provide an easy to use design-time designer as shown in image below:
