Hi,
FindAncestor RelativeSource only supports 'Self' and 'TemplatedParent',
but I have to bind
the width of a popup to
the width of
the page.
Giving
the page a name causes problems because sometimes it will
throw exceptions saying a control with that name is already present in
the visual tree.
<Popup IsOpen="True"
Width="{Binding ElementName=BordPage, Path=Width}"
Height="{Binding ElementName=BordPage, Path=Height}">
Background information:
I'm using a SL4 navigation based application here. BordPage is a navigation page,
which I'm using multiple times
within the application. So giving it a name in
the page itself is not really a good idea,
but I don't know how else I can bind to
the width and height of
the page.
What I'm trying to do is have a black border (with opacity 0.8) cover
the entire screen,
(including
the controls of
the MainPage). Then on top of that I want to display some other
controls.
Since
the application is touch controlled, providing
the user with a ComboBox to select a value doesn't really work wel. Instead I want to show this black overlay window with a listbox taking up most of
the screen so
the user can simply touch
the value he wants with a single click.
Update: I just realized I can use
the ChildWindow class to do this.
But my original question remains.
