since you have to support multiple screen resolutions in Windows 8 Metro Apps I want to split up my RichTextBlock to show text that would be cut off in a RichTextBlockOverflow control (or multiple controls, depending how much text I have to show). In order to determine if I have to show an additional RichTextBlockOverflow-Control I check the HasOverflowContent-Property of my RichTextBlocks. But it always returns false.
It's super easy to reproduce:
- Create a new "Windows Store -> Blank App"
Replace the xaml of MainPage.xaml with the following code:
<StackPanel Orientation="Horizontal" Background="{StaticResource ApplicationPageBackgroundThemeBrush}"> <RichTextBlock x:Name="test1" Width="100" Height="300" OverflowContentTarget="{Binding ElementName=test}"> <Paragraph> lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s lkj halks dflkjha skld fkla hsdkl hfakl dsflk hasdkl fakl hsdklf halks dflka jhsdhfklaj hsdklf jhakls dflkaj hsdlkfjh alks dflkajh s </Paragraph> </RichTextBlock> <RichTextBlockOverflow x:Name="test" Width="100" Height="300" /> </StackPanel>
Then go the code behind file (MainPage.xaml.cs) and replace the constructor with that code:
public MainPage()
{
this.InitializeComponent();
if (test.HasOverflowContent)
{
// Will never be entered
}
if (test1.HasOverflowContent)
{
// Will never be entered
}
}
Set a breakpoint in the on this.InitializeComponent() and see how the HasOverflowContent will never be true.
What am I doing wrong? Or is it a bug in .NET?
Any help would be very appreciated ;)
