Not sure if this has been reported, but when i change the Visibility of a Button control i get the following error:
ExceptionObject {System.Exception: Error HRESULT E_FAIL has been returned from a call to a COM component.

Changing the Visibility of a TextBox and TextBlock are fine
Here the section of my code, it's pretty straight forward:
public static
readonly DependencyProperty CurrentModeProperty =
DependencyProperty.Register("CurrentMode",
typeof(ControlMode),
typeof(MyClass),
new PropertyChangedCallback(CurrentModeChangedCallback));
Hello, from the stack trace, it looks like you're setting the Button's Visibility to Collapsed in its Click event handler. This is a known issue. But I just tried that on an internal Beta2 build, and it works fine. So hopefully this issue has already been
fixed. Meanwhile you can set Opacity to 0 or set Both Width and Height to 0.

Hi Yi-Lun thanks for the reply. Yes i have a work around at the moment, in fact the bug has led me to a better design.
internal Beta2 hey! Do we proles get to have a squiz with Beta2 or do we have to wait for the Release.
