VisibilityToBoolConverter is not working

    Question

  • Hello guru-guys!

    I am a new to Microsoft Blend 4 and trying to use the data binding option.

    The case is to hide a button until the required checkbox is checked.

    My steps:

    0) Making my button collapsed;

    1) Entering Data Binding of the button;

    2) Choosing Element Property ==> Choosing required  checkbox ==> choose IsChecked: (Nullable<Boolean)>

    3) Applying the converter VisibilityToBoolConverter ;

    4) OK

    And the error appears "Specified Cast not valid" in description to XAML

    Please help! What I'm doing wrong?
