Question

I have a problem when binding a Textbox to the Value of a Station Object. The values are displayed correctly, but when i edit the values on screen the Source isn’t updated. What am i doing wrong?

    public LineControl(ArrayList cells)
    {


        InitializeComponent();
        this.cells = cells;
        foreach (Cell c in cells)
        {
            AccordionItem aci = new AccordionItem();

            StackPanel sp = new StackPanel();
            aci.Content = sp;
            DataGrid dg = new DataGrid();

            if(c.Stations!=null)
            foreach (Station s in c.Stations)
            {

                TextBox t = new TextBox();
                t.DataContext = s;
                 Binding binding = new Binding();
                 binding.Mode = BindingMode.TwoWay;
                 binding.Source = s;
                 binding.Path = new PropertyPath("Value");
                 binding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
                 t.SetBinding(TextBox.TextProperty, binding);
                 //t.TextChanged += new TextChangedEventHandler(t_TextChanged);

                sp.Children.Add(t);
            }
            acc.Items.Add(aci);
        }
}

My Station Class looks like

class Station
{
    public int Id { get; set; }
    public String Name { get; set; }
    public int Value { get; set;  }

}

In my XAML there isn’t anything significant:

     <UserControl x:Class="Knowles_ShiftreportEditor.LineControl"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:toolkit="clr-   namespace:System.Windows.Controls;assembly=System.Windows.Controls.Layout.Toolkit"
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="100">
<Grid>

    <toolkit:Accordion Width="100"  Name="acc" SelectionMode="One" Loaded="acc_Loaded">
    </toolkit:Accordion>
</Grid>

Have you tried implementing INotifyPropertyChanged on your Station class? Also, what is the type used for your Stations collection at the top of your foreach loop?
