                  <LineBreak/>
                  The value of the "AutoSelectBehavior" property determines whether the content of the AutoSelectTextBox will be selected or not when the control gets the focus.

                  <LineBreak/>

                  <LineBreak/>
                  <LineBreak/>
                  Setting the "MaxLength" of the text box allows the focus to move from the AutoSelectTextBox once the max length has been reached.
               In the following "Telephone Number" fields, the "MaxLength" properties of the controls have been set to 3, 3, and 4.

                  <LineBreak/>
                  Setting "AutoMoveFocus" to true also allows navigating the focus through the controls using the arrow keys to move the focus up, down, left, or right. 
               You are no longer limited to the "left-right" navigation of the "Tab, Shift-Tab" keys.

         </RichTextBox>
