textblock

I'm looking for a simple way to change the foreground color of a TextBlock based on the color of what is behind it, so that it is more readable. Since an image is more explicit than words, here's what I want: I assume it could be done with a custom shader effect, but I have no idea how to create it... Anyway, perhaps there is a simpler solution. Any idea would be welcome! loxxy Assuming the above is a progressbar, here is a great solution: WPF progress bar with dynamic text & text color update Quick and dirty method: Add both the white and grey textblocks, ensuring the white textblock is "on

i replace the ContentPresenter in the DataGridCell 's Template with a TextBlock an now i search for the correct Binding to the content. The normal way is Text="{TemplateBinding Content} for the TextBlock - it doesn't work. Also Text="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Content, Mode=TwoWay}" doesn't work correct. Any other ideas? Suppose you have changed the DataGridCell Template to the following <ControlTemplate TargetType="{x:Type DataGridCell}"> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="

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 Line . Any help would be truly appreciated. Thanks in advance. ANSWER It seems that you can use

Gaurang Gaurang Gaurang Gaurang Gaurang Gaurang Gaurang Gaurang Gaurang Gaurang Gaurang I am working in WPF to create a text ticker. I am able to move the text from right to left forever but my problem is, that I want to move the same text seamlessly to create the above effect(Just like the stock exchange ticker). The above text must move endlessly. How can I achieve it? So from reading your question i'm not really sure what you want. Do you want a text, that scrolls out of the textbox, and starts over, like most marquee controls/functions. Or do you want some text that runs over and over in

The XAML below does not work (the text does not change when mousing over): <Window.Resources> <Style TargetType="TextBlock"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter Property="Text" Value="hover"/> </Trigger> </Style.Triggers> </Style> </Window.Resources> <Grid> <TextBlock Text="original"/> </Grid> But, if the Text attribute is missing: <Grid> <TextBlock/> </Grid> The text does change on mouse over. Anybody knows the theory behind this? It's a DependencyProperty precedence issue, when you actually set the property as in: <TextBlock Text="original"/> that takes

I have a wpf textblock as below: <TextBlock Text="{Binding [someViewModel].SomeVar.SomeSubVar.Name, TargetNullValue='-'}"/> At my viewmodel side, I'll have my own logic that in the end, SomeVar.SomeSubVar will be null. If I want to show a default value for this TextBlock I know I can declare and initiate SomeVar.SomeSubVar and assign default value into SomeVar.SomeSubVar.Name but I would like to use TargetNullValue instead. May I know which part is wrong? You might look at using FallbackValue http://msdn.microsoft.com/en-us/library/system.windows.data.bindingbase.fallbackvalue(v=vs.110).aspx
