if i may offer up an alternative approach, in my office, we have 4 dockable pane applications loading each time, we found that registering within each addin did not work, its been awhile since we first did this, but i suspect similar issue. Instead, we run postcommand inside a loader.dll (this also loads a bunch of other custom addins, but not important).
- First, both the loader and dockable application have .addin file associated with them.
- With the loader addin, the dockable registration through postcommand is called in the Idling event, after everything else is run. The form is not shown at this point
- The loader addin also creates a button for showing the form when needed.
Heres the relevant code.
From the loader dll:
private void RevitisIdling(object sender, IdlingEventArgs e)
{
UIApplication _uiapp = sender as UIApplication;
RevitCommandId typ_det_cmd =
RevitCommandId.LookupCommandId("81799b43-c658-4233-a362-cc232d9fc06c");
if (_uiapp.CanPostCommand(typ_det_cmd))
{
_uiapp.PostCommand(typ_det_cmd);
}
_uiapp.Idling -= RevitisIdling;
}
Dockable Application Registration Command, from Command.cs
[Transaction(TransactionMode.Manual)]
public class TypDetailRegister : IExternalCommand
{
private TypDetForm TheForm;
private Application _app;
private UIApplication _uiapp;
private List<ViewProperties> _viewList = new List<ViewProperties>();
private ExternalCommandData _commdata;
private Document _typdoc;
private Document _doc;
DockablePane _pane;
public Result Execute(ExternalCommandData commdata, ref string msg, ElementSet elemset)
{
_commdata = commdata;
_uiapp = _commdata.Application;
_app = _uiapp.Application;
TheForm = new TypDetForm();
_uiapp.RegisterDockablePane(GlobalVars.dockid, "Typ Detail Selector", TheForm as IDockablePaneProvider); //register the dockbable pane
_app.DocumentOpening += NotQuiteOpen; //event for right before a project is opened
_app.DocumentOpened += TypDetViews; //event for after the project finishes opening
_app.DocumentClosing += NotQuiteClosed; //event for right beforea proejct is closed
//update the list when a view is activated or the pane is opened
//_uiapp.ViewActivated += Application_ViewActivated;
_uiapp.DockableFrameVisibilityChanged += Application_VisibilityChanged;
return Result.Succeeded;
}
}
public class GlobalVars
{
public static DockablePaneId dockid = new DockablePaneId(new Guid("81799b43-c658-4233-a362-cc232d9fc06c"));
public static bool DoTheThings { get; set; }
}
Setup of the dockable pane itself, from xaml.cs:
public partial class TypDetForm : Page, IDockablePaneProvider
{
private TypDetailRegister TypDetViews;
public Document TypDoc;
private Document ThisDoc;
private Application App;
private UIApplication UiApp;
private CheckBox _headerBlock;
private Expander _localexp;
private bool _txtexpansion = false; //bool to force "whole word" search on space bar
public TypDetForm()
{
InitializeComponent();
}
public void SetupDockablePane(DockablePaneProviderData data)//set some default parameters
{
data.FrameworkElement = this;
data.InitialState = new DockablePaneState();
data.InitialState.DockPosition = DockPosition.Right;
}
}
and Lastly, showing the form, from Command.cs:
[Transaction(TransactionMode.Manual)]
public class TypDetailShow : IExternalCommand
{//this class is literally just for show....shows the form.
public Result Execute(ExternalCommandData commdata, ref string msg, ElementSet elemset)
{
try
{
UIApplication _uiapp = commdata.Application;
DockablePane pane = _uiapp.GetDockablePane(GlobalVars.dockid);
//if the window is displayed when the button is clicked, hide the window and uncheck the box
if (pane.IsShown())
{
pane.Hide();
}
//otherwise, show the window and check the box
else
{
pane.Show();
}
}
catch (Exception ex)
{
// show error info dialog
TaskDialog.Show("Info Message", ex.Message);
}
return Result.Succeeded;
}
}
