Cannot InitializeComponent(); WPF Docked Pane

[esatis]

Hi, 

I have spent few days trying to figure out how to dock simple WPF pane, went through all available  tutorials yet something is not working and I cannot call InitializeComponent(); when initializing my WPF Page. 

First of all I found out that there are two ways to register dockable pane.

1. UIControlledApplication.RegisterDockablePane
2. UIApplication.RegisterDockablePane

Is there a difference? 

The example at UIControlledApplication.RegisterDockablePane shows this:

public Result OnStartup(UIControlledApplication application)
{
   // Create our pane provider and register it with the application
   PaneProvider prov = new PaneProvider();
   DockablePaneId id = new DockablePaneId(Guid.NewGuid());
   application.RegisterDockablePane(id, "test", prov);

   return Result.Succeeded;
}

 But if I create ViewPane (PaneProvider) like this:

public partial class ViewPane : Page, IDisposable, IDockablePaneProvider
{
	public ViewPane()
	{
		Debug.WriteLine("[ViewPane]");
		try
		{
			Debug.WriteLine("[ViewPane][InitializeComponent]");
			InitializeComponent();
		}
		catch (Exception ex)
		{
			TaskDialog.Show("[ViewPane] Error", ex.Message);
		}
	}

I get error: 
Could not load file or assembly 'AutomateWallCreation, Version=0.0.0, Culture=neutral' or one of its dependencies. The system cannot find the file specified.

The pane is registered but black.

If I go the other way, with UIApplication.RegisterDockablePane:

and use ApplicationInitialized event like this:

public Result OnStartup(UIControlledApplication UIpplication)
{
	UIpplication.ControlledApplication.ApplicationInitialized += RegisterViewPane;

	return Result.Succeeded;
}
private void RegisterViewPane(object sender, Autodesk.Revit.DB.Events.ApplicationInitializedEventArgs e)
{
	Debug.WriteLine("[RegisterViewPane]");
	var registerPaneCommand = new RegisterDockablePaneManager();
	registerPaneCommand.Execute(new UIApplication(sender as	Autodesk.Revit.ApplicationServices.Application));
}

///
///differenct class
///
[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
internal class RegisterDockablePaneManager : IExternalCommand
{
	public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
	{
		return Execute(commandData.Application);
	}

	public Result Execute(UIApplication application)
	{

		Debug.WriteLine("[RegisterDockablePaneManager]");

		var data = new DockablePaneProviderData();
		var pane = new ViewPane();
		DTO.viewPane = pane;

		data.FrameworkElement = pane as FrameworkElement;

		var dpid = new DockablePaneId(DockablePaneIdentifierManager.GetViewPaneGuid());
		application.RegisterDockablePane(dpid, "ViewPane", DTO.viewPane as IDockablePaneProvider);
		return Result.Succeeded;
	}
}

I get same error: 

Could not load file or assembly 'AutomateWallCreation, Version=0.0.0, Culture=neutral' or one of its dependencies. The system cannot find the file specified.

The pane is registered but black.

What could be the reason for failure to InitializeComponent(); at startup ?

This sounds like your .Addin file is not finding the compiled dll in the correct location. Check that first. The code looks fine, however can you verify that

var dpid = new DockablePaneId(DockablePaneIdentifierManager.GetViewPaneGuid());

is matching your applications GUID (the ClientID in your .Addin file)?

[ricaun]

Your implementation with UIControlledApplication.RegisterDockablePane should work.

What do you have inside the ViewPane.xaml?

And where is your IDockablePaneProvider.SetupDockablePane code?

Should have something like this:

public void SetupDockablePane(DockablePaneProviderData data)
{
    data.FrameworkElement = this;

    data.InitialState = new DockablePaneState
    {
        DockPosition = DockPosition.Tabbed,
    };
}

Hi, the GUID is unique. The .addin is finding the .dll. The Addin Ribbon buttons and even the docked panes show up but just black.

Hi, yes, I start to think that there is something fishing going on... Here is my code for ViewPane.xaml

using Autodesk.Revit.UI;
using System;
using System.Diagnostics;
using System.Windows;
using System.Windows.Controls;

namespace AutomateWallCreation.Views
{
	public partial class ViewPane : Page, IDisposable, IDockablePaneProvider
	{
		public ViewPane()
		{
			Debug.WriteLine("[ViewPane]");
			try
			{
				Debug.WriteLine("[ViewPane][InitializeComponent]");
				InitializeComponent();
			}
			catch (Exception ex)
			{
				Debug.WriteLine("[ViewPane] Error: " + ex.Message);
			}
		}

		public void Initialize()
		{
			Debug.WriteLine("[ViewPane][Initialize]");
		}

		public void Dispose()
		{
			this.Dispose();
		}

		public void SetupDockablePane(DockablePaneProviderData data)
		{
			data.FrameworkElement = this as FrameworkElement;
			data.InitialState = new DockablePaneState
			{
				DockPosition = DockPosition.Right
			};
		}
	}
}

 I even tried to set up it like this:

public void CreatePage()
{
	Debug.WriteLine("[InitializeComponent]");
	InitializeComponent();
}
/// in App.cs
public Result OnStartup(UIControlledApplication UIpplication){
UIpplication.ControlledApplication.ApplicationInitialized += RegisterViewPane;
}

private void RegisterViewPane(object sender, Autodesk.Revit.DB.Events.ApplicationInitializedEventArgs e)
{
	Debug.WriteLine("[InitializeChatPane]");
	_viewpane.CreatePage();
}

Or pass it around with DTO, with no results.
InitializeComponent() just can't find dll at startup.

The code of the ViewPane.xaml, I mean what is the content of your Page. 

There is a Grid with a red background or you have something more complex.

One easy way to test is create a new Page with a Grid and a background in red.

And you could add the Page in a Windows. But in your case the Initialize Component is failing, that means the problem is the ViewPane.xaml file.

Try to create and show a empty Windows, by the looks is not a DockablePane problem.

<AssemblyVersion>0.0.0</AssemblyVersion>

Thank you all for suggestions, my two day struggle is over! 😤 😌
This one line in the sdk style .csproj was the fault for all the missing .dll errors. 

So where do I put the Assambly version information ? 

[ricaun]

I noticed that the version was zero in the code:

/AutomateWallCreation;V0.0.0;component/views/viewpane.xaml

Didn't know that would break the wpf.

You could use the <Version>.

<Version>1.0.0</Version>

Now I don't know if the problem is the 0.0.0 or the AssemblyVersion, I guess is the zero version.
