copied!<p>EDIT:</p> <p>This line,</p> <p><code><props:Resources x:Key="Resources"/></code></p> <p>is a bad approach to accesing the Project.Properties.Resources namespace. It causes awkward glitches when recompiling.</p> <p>Much better to use <code>x:Static</code> to do somthing like this,</p> <p><code>Text="{x:Static props:Resources.SomeText}"</code></p> <p>in your binding. Thx to <a href="https://stackoverflow.com/questions/665764/how-to-fetch-string-from-resource-to-assign-in-wpf-resource-section-in-xaml">Ben</a></p> <hr> <p>Okay, this is how I did it. It's not perfect but it works.</p> <p>Remember, there is a project resource called FormattedText.</p> <p>cs:</p> <pre class="lang-cs prettyprint-override"><code>// TextBlock with a bindable InlineCollection property. // Type is List(Inline) not InlineCollection becuase // InlineCollection makes the IDE xaml parser complain // presumably this is caused by an inherited attribute. public class BindableTextBlock : TextBlock { public static readonly DependencyProperty InlineCollectionProperty = DependencyProperty.Register( "InlineCollection", typeof(List<Inline>), typeof(BindableTextBlock), new UIPropertyMetadata(OnInlineCollectionChanged)); private static void OnInlineCollectionChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { BinableTextBlock instance = sender as BindableTextBlock; if (instance != null) { List<Inline> newText = e.NewValue as List<Inline>; if (newText != null) { // Clear the underlying Inlines property instance.Inlines.Clear(); // Add the passed List<Inline> to the real Inlines instance.Inlines.AddRange(newText.ToList()); } } } public List<Inline> InlineCollection { get { return (List<Inline>)GetValue(InlineCollectionProperty); } set { SetValue(InlineCollectionProperty, value); } } } // Convertor between a string of xaml with implied run elements // and a generic list of inlines [ValueConversion(typeof(string), typeof(List<Inline>))] public class StringInlineCollectionConvertor : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { string text = value as String; // a surrogate TextBlock to host an InlineCollection TextBlock results = new TextBlock(); if (!String.IsNullOrEmpty(text)) { //Arbritary literal acting as a replace token, //must not exist in the empty xaml definition. const string Replace = "xxx"; // add a dummy run element and replace it with the text results.Inlines.Add(new Run(Replace)); string resultsXaml = XamlWriter.Save(results); string resultsXamlWithText = resultsXaml.Replace(Replace, text); // deserialise the xaml back into our TextBlock results = XamlReader.Parse(resultsXamlWithText) as TextBlock; } return results.Inlines.ToList<Inline>(); } // Not clear when this will be called but included for completeness public object ConvertBack( object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { String results = String.Empty; InlineCollection inlines = value as InlineCollection; if (inlines != null) { //read the xaml as xml and return the "content" var reader = XElement.Parse(XamlWriter.Save(inlines)).CreateReader(); reader.MoveToContent(); results = reader.ReadInnerXml(); } return results; } } </code></pre> <p>xaml:</p> <pre class="lang-xml prettyprint-override"><code><Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:props="clr-namespace:Project.Properties" xmlns:local="clr-namespace:Project"> <Window.Resources> <props:Resources x:Key="Resources"/> <local:StringInlineCollectionConvertor x:Key="InlineConvert"/> </Window.Resources> <local:BindableTextBlock InlineCollection=" {Binding Source={StaticResource Resources}, Path=FormattedText, Converter={StaticResource InlineConvert}}"/> </Window> </code></pre> <p>I made 2 classes. A sub-classed TextBlock with a "bindable" InlineCollection and an IValueConverter to convert the collection from and to a String.</p> <p>Using InlineCollection directly as the type of the property made VS2010 complain, although the code still ran fine. I changed to a generic list of Inlines. I assume that there is an inherited attribute telling VS that the InlineCollection has no constructor.</p> <p>I tryed making the InlineCollection property the BindableTextBlock's ContentProperty but ran into issues and out of time. Please feel free to take the next step and tell me about it.</p> <p>I apologise for any errata but this code had to be transcribed and sanitised.</p> <p>If there is a better way of doing this, surely there must be, please tell me that too. Wouldn't it be nice if this functionality was built in or, have I missed something?</p>
