In my below mentioned reqular expression, how can i add double quotes ?
<asp:RegularExpressionValidator SetFocusOnError="true" ID="rev" runat="server"
Display="None" ValidationGroup="question" ErrorMessage="" ControlToValidate="txtQuestion"
ValidationExpression="^[0-9a-zA-Z-/'? ]+$"> </asp:RegularExpressionValidator>
This sounds like it may be an XML question more than regex. Have you tried just using
"?
