Hello,

i didn't use noesis since a while, i really missing something new here.
I just try to bind a text property from a usercontrol to a textblock in xaml
I did that lot of times before, but now it doesn't work any more !

It appear you change the code to accomplish it can you tell me more about the new method.

xaml

<Grid x:Name="LayoutRoot"  TextElement.FontFamily="../Fonts/#Arial">
		<Rectangle Fill="#FFF4F4F5" Stroke="Black"/>
		<StackPanel Margin="172.967,107" Orientation="Vertical" HorizontalAlignment="Center" VerticalAlignment="Center">
			<TextBlock x:Name="Labeltxt" Text="{Binding ElementName=root, Path=Text}" TextWrapping="Wrap" FontSize="32" Margin="0,0,-0.001,0" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black"/>
			<Button x:Name="AnnulerBtn" Content="Annuler" Style="{DynamicResource RedBtn}" VerticalAlignment="Top" FontSize="24" FontWeight="Bold" Foreground="White" Margin="0,5,0,0" Height="80"/>
			<Button x:Name="ValiderBtn" Content="Valider" Style="{DynamicResource GreenBtn}" FontSize="24" FontWeight="Bold" Foreground="White" Margin="0,5,0,0" Height="80"/>
		</StackPanel>
	</Grid>

c#


using Noesis;
using System;
using UnityEngine;


    [Noesis.UserControlSource("Assets/Gui/UserControls/PopUp.xaml")]

    public class PopUpControl : UserControl
    {

        public DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string),
        typeof(PopUpControl), new PropertyMetadata(""));

        public string Text
        {
            get { return (string)GetValue(TextProperty); }
            set { SetValue(TextProperty, value); }
        }

        private Button Annulerbtn;
        private Button.ClickHandler annulerEventHandler;


        public Button.ClickHandler AnnulerEventHandler
        {
            set
            {
                annulerEventHandler = value;
                if (Annulerbtn != null)
                {
                    Annulerbtn.Click += annulerEventHandler;
                }
            }
        }

        private Button Validerbtn;
        private Button.ClickHandler validerEventHandler;

        public Button.ClickHandler ValiderEventHandler
        {
            set
            {
                validerEventHandler = value;
                if (Validerbtn != null)
                {
                    Validerbtn.Click += validerEventHandler;
                }
            }
        }


        public void OnPostInit()
        {
            Validerbtn = (Button)FindName("ValiderBtn");
            Annulerbtn = (Button)FindName("AnnulerBtn");
            Annulerbtn.Click += annulerEventHandler;
            Validerbtn.Click += validerEventHandler;
        }

    }

Sorry if the question seem so stupid !

System.Exception: DependencyProperty 'Text' already registered to type 'PopUpControl'

This error appears because you are defining the Text DependencyProperty as an instance field instead of static, so every time an instance of your PopUpControl is created, the Text property is registered again in the native type.

You have to change your UserControl code to:

using Noesis;
using System;
using UnityEngine;

[Noesis.UserControlSource("Assets/Gui/UserControls/PopUp.xaml")]
public class PopUpControl : UserControl
{
    public static DependencyProperty TextProperty = DependencyProperty.Register(
        "Text", typeof(string), typeof(PopUpControl), new PropertyMetadata(""));

    public string Text
    {
        get { return (string)GetValue(TextProperty); }
        set { SetValue(TextProperty, value); }
    }

    private Button Annulerbtn;
    private Button.ClickHandler annulerEventHandler;

    public Button.ClickHandler AnnulerEventHandler
    {
        set
        {
            annulerEventHandler = value;
            if (Annulerbtn != null)
            {
                Annulerbtn.Click += annulerEventHandler;
            }
        }
    }

    private Button Validerbtn;
    private Button.ClickHandler validerEventHandler;

    public Button.ClickHandler ValiderEventHandler
    {
        set
        {
            validerEventHandler = value;
            if (Validerbtn != null)
            {
                Validerbtn.Click += validerEventHandler;
            }
        }
    }

    public void OnPostInit()
    {
        Validerbtn = (Button)FindName("ValiderBtn");
        Annulerbtn = (Button)FindName("AnnulerBtn");
        Annulerbtn.Click += annulerEventHandler;
        Validerbtn.Click += validerEventHandler;
    }
}

great thanks you

So i just take the exemple in the databinding tutorial sorry what is the difference between ?

For the windows store build i should do something wrong but i can't see any todo in your documentation.

class View2: UserControl
{
    public DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string),
        typeof(View2), new PropertyMetadata(""));

    public string Text
    {
        get { return (string)GetValue(TextProperty); }
        set { SetValue(TextProperty, value); }
    }
}

The C# code in that sample of the documentation is wrong, it should be a static field.
Sorry for the inconveniences

I just fixed it, thanks.

Great

i really tinking i'm crazzy !

*I saw in your documentation, that in unity 5.1 we don't have to had the reference :

Noesis.dll and NoesisUnityRenderHook.dll

to the reference of the VS project.

I'm in 5.1.2 so i did nothing but when i open my project i can't see noesis.dll in the references, is it correct ?

Thanks you

Yes, it is correct. That .dll is a native library, so you don't need to have a reference to that dll in your VS project.

But you can check that all our scripts under Plugins are included in the firstpass assembly project, so they will be compiled and could be used by your application scripts.
