Gets or sets whether an end-user can insert return characters into a text. This is a dependency property.
true to allow return characters to be accepted and processed by the editor; otherwise, false.
If the MemoAcceptsReturn property is set to true and the text is being edited within the dropdown, the ENTER key is processed by the editor, and results in a new text line. Otherwise, if the MemoAcceptsReturn property is set to false, return characters are ignored. Return characters, however, can be inserted in code by adding appropriate characters (for instance, "\r\n" for C#) to the Text property.
