Something I found missing when I was trying to get a dockablepane WPF project up and running is how to get read/write access to the WPF interactively. The basics are, make sure the WPF is a WPF page and the class has IDockablePaneProvider as a partial class in the page.XAML.cs file.

public partial class SheetGenerator : Page, IDockablePaneProvider
{
private EventHandlers eventHandler;
private ExternalEvent extEvent;
// public EventHandlers eventHandler;
// public ExternalEvent extEvent;
public void SetupDockablePane(DockablePaneProviderData data)
{
data.FrameworkElement = this as FrameworkElement;
data.InitialState = new DockablePaneState();
data.InitialState.DockPosition = DockPosition.Right;
data.VisibleByDefault = false;
}
public SheetGenerator(ExternalEvent exEvent, EventHandlers handlers)
{
InitializeComponent();
eventHandler = handlers;
extEvent = exEvent;
}
in your main app, create class instances of the WPF page(s).

dPlist.Add(LegendCopyPaneId);
return dPlist;
}
public Result OnShutdown(UIControlledApplication application)
{
return Result.Succeeded;
}
public Result OnStartup(UIControlledApplication application)

// register the dockablepanes
application.RegisterDockablePane(SheetGenPaneId, "Sheet Generator", SheetGenPane as IDockablePaneProvider);

utilities.AddRibbonPanel(application);
application.ControlledApplication.DocumentOpened += new EventHandler<Autodesk.Revit.DB.Events.DocumentOpenedEventArgs>(Application_DocumentOpened);
return Result.Succeeded;
}
// actions for when a project is opened
private void Application_DocumentOpened(object sender, DocumentOpenedEventArgs args)
{
Document doc = args.Document;
cDoc = doc;
UIApplication UIApp = new UIApplication(doc.Application);
Utilities utilities = new Utilities();
try
{
// utility that loops through the dockpane instances and closes them
utilities.Hidepanes(UIApp);
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
}
To open the dockablepanes, call dockpane.show from the command
public class MultiSheet : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
Document doc = commandData.Application.ActiveUIDocument.Document;
UIApplication UIApp = new UIApplication(doc.Application);
Utilities utils = new Utilities();
// hide all the panes again
utils.Hidepanes(UIApp);
// get the dockable pane you want to use
DockablePane pid = UIApp.GetDockablePane(BIMApp.SheetGenPaneId);
// initialise the WPF controls through classes and functions
utils.MakeLegendList(UIApp, BIMApp.SheetGenPane.LegendSelectorListView);
utils.MakeSheetList(UIApp, BIMApp.SheetGenPane.SheetTamplateSelectorListview);
utils.MakeTitleBlockList(UIApp, BIMApp.SheetGenPane.TitleBlockSelector);
utils.MakeSheetParameterList(UIApp);
utils.ViewParametersList(UIApp, BIMApp.SheetGenPane.ViewFilterParameterCombo);
utils.MakeViewList(UIApp, BIMApp.SheetGenPane.ViewSelectionList, BIMApp.SheetGenPane.ViewFilters, "Family");
utils.MakeLevelGrid(UIApp, BIMApp.SheetGenPane.LevelSettings);
// show the correct dockable pane for the current command
pid.Show();
UIApp.ViewActivated += UIApp_ViewActivated;
return Result.Succeeded;
}
// function to handle views changing in the editor
private void UIApp_ViewActivated(object sender, ViewActivatedEventArgs e)
{
UIApplication UIApp = sender as UIApplication;
if (UIApp != null)
{
Utilities utils = new Utilities();
ViewType vt = e.CurrentActiveView.ViewType;
if (vt == ViewType.DrawingSheet)
{
BIMApp.SheetGenPane.SheetParameterDataGrid.IsEnabled = true;
utils.MakeSheetParameterList(UIApp);
}
else
{
BIMApp.SheetGenPane.SheetParameterDataGrid.IsEnabled = false;
}
}
// throw new NotImplementedException();
}
}
Here's the function for hiding the DockablePanes:-
public void Hidepanes(UIApplication application)
{
List<DockablePaneId> dockablePanes = BIMApp.DockPanes();
// Loops the static list defined in the main appliction
foreach (DockablePaneId dPID in dockablePanes)
{
DockablePane dpn = application.GetDockablePane(dPID);
dpn.Hide();
}
}
These examples are a bit long winded but they are from an active application project with multiple dockable panes where reopening Revit is not an option. Hope this helps.
