Description
I'm interested in multilevel navigation hierarchy and TreeList navigation inside NavBar group item. I'm thinking about solution similar to MSOutlook NavBar and mail folders structure inside. How can it be implemented?

Solution
Applies to:
eXpressApp Framework To accomplish this, do the following: 1) Add a custom Template as shown in the How to: Customize a Template help topic. 2) By default, the Navigation Action is displayed via the NavBarActionContainer in the Windows Forms application. This Action Container creates the XtraNavBar control for the Action.
To create a tree list instead of the navigation bar, implement the TreeListActionContainer and TreeListActionNode classes as shown in the attached project. 3) Invoke the Designer for the MainForm Template added in step 1. Remove the existing NavBarControl from the form, then drag and drop the newly created TreeListActionContainer component on the form and set its Dock property to Fill. 4) Find all the entries of the deleted NavBarControl in the template's files and replace them in the required places with the TreeListActionContainer control. For instance:
[C#]
this.cOpenModule = new Solution1.Module.TreeListActionContainer();
[VB.NET]
Me.cOpenModule = New Solution1.Module.TreeListActionContainer()
5) Pay special attention to the following lines in the MainForm file. Modify the code as follows:
[C#]
List<IActionContainer> containers = new List<IActionContainer>();
containers.AddRange(new IActionContainer[]{
cAbout, cTools, cFile, cObjectsCreation, cPrint, cExport, cExit, cRecordEdit,
cRecordsNavigation, cViewsHistoryNavigation, cFiltersSearch, cFilters,
cView, cOptions, cOpenModule, cDiagnostic
});
Initialize(mainBarManager, containers,
new IActionContainer[] { cObjectsCreation, cRecordEdit, cView, cPrint, cExport },
viewSitePanel, null);
[VB.NET]
Dim containers As List(Of IActionContainer) = New List(Of IActionContainer)()
containers.AddRange(New IActionContainer()
{
cAbout, cTools, cFile, cObjectsCreation, cPrint, cExport, cExit, cRecordEdit, cRecordsNavigation,
cViewsHistoryNavigation, cFiltersSearch, cFilters, cView, cOptions, cOpenModule, cDiagnostic
})
Initialize(mainBarManager, containers, New IActionContainer()
{ cObjectsCreation, cRecordEdit, cView, cPrint, cExport },
viewSitePanel, Nothing);
where cOpenModule is our TreeListActionContainer control. See Also:
