#region Dependency Properties

"HeaderText", typeof(string), typeof(OptionsPanel), null);


public string HeaderText
{
get { return (string)GetValue(HeaderProperty); }
set { SetValue(HeaderProperty, value); }
}

#endregion

}
}

As you may have noticed I have added X button and click event

But I don't know how to close it? What is the code?

 

Regards, Marko.
