Hiding Base Properties in PropertyGrid

Question

Hello friends,

I would like to hide some properties in the PropertyGrid... I used the code below to hide the ToolTip property for example.

            [BrowsableAttribute(false)]
            public new object ToolTip
            {
                get { return base.ToolTip; }
                set { base.ToolTip = value; }
            }

In VS2010, the ToolTip property is hidden after compiling the solution.

However, when I opened my project in Expression Blend 4, the ToolTip still appears on the PropertyGrid.

Any suggestion on how to resolve this issue? Thanks!
