    copied!<p>Basically, I am reading a value from an xml file and displaying that value in a text box. This text box is editable so the user can make changes to it and when the session ends that value gets stored back in the xml file.</p> <p>I know that the values correctly get stored and loaded to the text box. But I'm baffled as to why I cannot see the bound value that should be displayed in the text box.. </p> <p>This is the text box:</p> <pre><code>&lt;UserControl x:Class="test.myView" 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:ui="clr-namespace:test.myView" xmlns:local="test.myControls;assembly=test.mycontrols"&gt; &lt;UserControl.Resources&gt; &lt;ResourceDictionary&gt; &lt;ResourceDictionary.MergedDictionaries&gt; &lt;ResourceDictionary Source="Style.xaml"/&gt; &lt;/ResourceDictionary&gt; &lt;/UserControl.Resources&gt; &lt;StackPanel Margin="8"&gt; &lt;TextBlock Text="Starting URL"/&gt; &lt;TextBox Margin="0,5" FontSize="12" Height="30" Width="360" Text="{Binding myValue, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" Style="{StaticResource WaterMarkTextBox}" local:WaterMarkTextHelper.WatermarkText="ENTER Value" /&gt; &lt;/StackPanel&gt; </code></pre> <p></p> <p>This is the INotifyPropertyChanged:</p> <pre><code>public abstract class ViewModelBase : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected void RaiseChangeNotification(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } } </code></pre> <p>This is the property im binding to:</p> <pre><code>public string myValue { get { return _settings.myValue; } set { _settings.myValue= value; } } </code></pre> <p>I think it maybe because the value of the text box to empty before the code reaches the part where the start url is set using data binding. Does there exist a validate command in wpf that forces it to view the most up to date value?</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
