  Following function will allow only number and special characteres mentioned in regex now you can modify according yo your need.

  add the text in regex which you want to allow in textbox

  refer this one

  http://babasahebkale.blogspot.in/2012/11/allow-number-and-special-characters-in.html

    $(document).ready(function myfunction() {

              $("#<%= TextBox1.ClientID %>").keypress(function myfunction(event) {

                  var regex = new RegExp("^[0-9?=.*!@#$%^&*]+$");               

                  var key = String.fromCharCode(event.charCode ? event.which : event.charCode);

                   if (!regex.test(key)) {

                          event.preventDefault();

                          return false;

                      }              

                      return false; 

              });

          });

  <div><asp:TextBox ID="TextBox1" runat="server" /></div>

  <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
      <script type="text/javascript">
          $(document).ready(function () {
              $('.keyup-characters').keyup(function () {
                  $('span.error-keyup-2').remove();
                  var inputVal = $(this).val();
                  var characterReg = /^\s*[~!@#$%^&*\s]+\s*$/;
                  if (!characterReg.test(inputVal) && inputVal != '') {
                      $(this).after('<span class="error error-keyup-2">Invalid Character.</span>');
                  }
              });
          });
      </script>
  
  
      <asp:TextBox ID="txt" runat="server" CssClass="keyup-characters"></asp:TextBox>
      <br />
      <span class="error-keyup-2"></span>

  
  Sample code...if you still need to allow some more special characters...put that character inside [] (highlighted above)...it will refuse any character that is not inside [].
