问题 Is it possible to bind Text and StringFormat too? <TextBlock Text="{Binding Path=Price, StringFormat={Binding Path=DecimalPoints}}" /> DecimalPoints is constantly changing from F0 to F15 . Unfortunatelly the code above doesn't compile. 回答1: I think your best bet is definitely a converter. Then your binding would look like this: <TextBlock.Text> <MultiBinding Converter="{StaticResource StringFormatConverter }"> <Binding Path="Price"/> <Binding Path="DecimalPoints"/> </MultiBinding> </TextBlock

问题 I have a TextBlock I would like to pass a property of ' LineSpacing '. The thing with using " LineHeight " with LineStackingStrategy="BlockLineHeight" is that it also applies the LineHeight to the segment before the first line: How can I manage to preserve said ' LineSpacing ' without modifying the LineHeight before the first line? One thing I though might work is to separate each line in a Paragraph of a FlowDocument , since the Paragraph has a property Spacing Before Line and Spacing After

问题 I am trying to figure out the best way to create a style/trigger to set foreground to Red, when value is < 0. what is the best way to do this? I'm assuming DataTrigger, but how can I check for negative value, do i have to create my own IValueConverter? 回答1: If you are not using an MVVM model (where you may have a ForegroundColor property), then the easiest thing to do is to create a new IValueConverter, binding your background to your value. In MyWindow.xaml: <Window ... xmlns:local="clr

问题 How can I bind a WPF TextBlock to a text file? I want for the TextBlock to display the content of the file. 回答1: You need to read the file into a string in memory and bind to that string instead. View model: class ViewModel { public string FileText { get; set; } public void ReadFile(string path) { FileText = File.ReadAllText(path); } } XAML: <TextBlock Text="{Binding FileText}"/> 回答2: If you want the text to be formatted my inline markup you could look at the sub-class of TextBlock I made

问题 Let us say that I have an empty Textblock : textblock1.Text = ""; Then I only put Inlines content in it with these two statements: textblock1.Inlines.Add(new Run() { Text = "A. ", Foreground = Brushes.Red }); textblock1.Inlines.Add(new Run() { Text = responses.Current.Value, Foreground = Brushes.Black}); The amazing stuff is that I can visualize the content properly in my window, however the Text property of the Textblock keeps being empty! This causes a problem because I need to pass the

问题 I'm new to WPF and I've found some similar questions but can't quite figure out the last part. I have a ViewModel with an ObservableCollection that contains error messages. I want to display these on the form AND allow the user to select and copy all or part of the messages. (In the past in WinForm apps I used a RichTextBox for this, but I can't figure out how to bind to one to the collection in WPF.) I got the look I was after with the following xaml, but there is no built-in way to select

问题 I'm working on a simple chat application. Currently the messages are binded to a custom-styled listbox like this (simplified XAML): <ListBox ItemsSource="{Binding MessageCollection}"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Text}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Now I would like to be able to put images (like graphical smileys) into the displayed message text. Is there any way to achieve this using TextBlock (or any other standart component) or do
