use binding , converter.

public sealed class visibilitytoborderthicknessconverter : ivalueconverter { public object convert(object value, type targettype, object parameter, system.globalization.cultureinfo culture) { seek { var flag = (visibility)value; if (flag == visibility.visible) homecoming new thickness(0); else homecoming new thickness(1); } grab { homecoming new thickness(0); } } public object convertback(object value, type targettype, object parameter, system.globalization.cultureinfo culture) { throw new notimplementedexception(); } }

and xaml:

<scrollviewer name="blah"> <border borderthickness="{binding elementname=blah, path=verticalscrollbarvisibility , converter={staticresources visibilitytoborder}}"> </scrollviewer>
