Create new tool from code

[brmassa]

I am having problems creating a dock/tool using code.

Using AXAML, I was able to create a given tool using:

          <ToolDock x:Name="LeftPane" Id="LeftPane">
            <Tool x:DataType="Tool" Title="Properties">
              <vm:SubTreeView></vm:SubTreeView>
            </Tool>
          </ToolDock>

---

But using C# code, the tab is created but no content is displayed:
SubTreeView.axaml.cs

using Avalonia.Controls;
using Dock.Model.Core;

namespace MyNameSpace
{
    public partial class SubTreeView : UserControl
    {
        public SubTreeView()
        {
            InitializeComponent();
        }
    }
}

SubTreeView.axaml.cs

<UserControl xmlns="https://github.com/avaloniaui"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  x:Class="MyNameSpace.SubTreeView"
  x:CompileBindings="True"
  xmlns:vm="using:MyNameSpace"
  x:DataType="vm:SubTreeViewModel">
  <Grid Focusable="True">
    <TextBlock Text="{Binding Id}" Padding="2" />
    <TextBlock Text="{Binding Title}" Padding="2" />
    <TextBlock Text="{Binding Context}" Padding="2" />
  </Grid>
</UserControl>

`SubTreeViewModel.cs

using Dock.Model.Avalonia.Controls;

namespace MyNameSpace
{
    public class SubTreeViewModel : Tool
    {
    }
}

Missed the code that I tried to create the dock:

            var subTreeView = new SubTreeView();
            var subTreeViewModel = new SubTreeViewModel
            {
                Id = "SubTree",
                Title = "SubTree"
            };
            DockFactory.AddDockable(LeftPane, subTreeViewModel);

what's the proper way to do it? @wieslawsoltes

I think I figured it out after some hours of reverse engineering. Unfortunately I did not find any documentation at all.

I will add a minimal demo app that uses Avalonia 11.0.0preview8 and Dock.Avalonia 11.0.0preview8.2.
DockTest.zip

Important points are:

• Use namespace Dock.Model.Mvvm.Controls for the documents or tools.

• Creating the views relys on a ViewLocater that has special requirements for the naming scheme of views and their viewmodels.

• Assign the ViewLocator in your App.axaml with <Application.DataTemplates> tag.

Note: This Example uses a UserControl as content for the documents without XAML. (pure C#)

thanks, man. I really appreciate it. I however migrated by code to another Docking system.

Which one do you use?
