Text Property in TextBox or any other input controls(eg:- AutoCompleteBox, Editable ComboBox etc)

[Abhi]

Hi,

    When selecting the text inside the TextBox it should select in the following way

     1. For mouse single click for cursor position

     2  For mouse double click it should select a word

     3. For mouse triple click it should select whole text
    Normal behavior which we generally see in different sites..............Eg:- Telerik ClientLogIn UserNameBox

    How to achieve this is in silverlight TextBox?
    pls give any solution
