[Solved] Getting Error when adding ToolTipService

[Ben Hayat]

Hi;

I added ToolTipService Via VS to the Expander tag, but I get runtime error "Unknown attribute".

Secondly, at design time, if I change the font size for t he header of t he expander, it changes all the fonts of all the controls inside Expander.

Hopefully this can be fixed for Q1!
Thanks!
..Ben

Hi ..Ben,

you need to previx the ToolTipService control with the namespace from where it comes. It is a bug in the silverlight framework at this moment and this is the workaround.

All the best,
