javascript - Mark up ASP.net validator -

-

i have created simple webform using designer in asp.net (vs2013). system works well, had use few textboxes , custom validation controls toolbox. form checks client sided if input correct , shows error message if not.

however errormessage gets shown on page in ugly red text atm. mark-up error message, example use jquery fade-in function on error or use custom javascript hook in emited js asp.

what , best way this?

code:

<%@ page language="c#" autoeventwireup="true" codefile="registreren.aspx.cs" inherits="registreren" %>  <!doctype html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server">     <script type="text/javascript" src="scripts/jquery.js"></script>       <title></title>     <link href="websitestyle.css" type="text/css" rel="stylesheet" /> </head> <body>     <form id="form1" runat="server">     <div style="height: 244px">          <table class="auto-style1">             <tr>                 <td class="auto-style2" rowspan="1">username</td>                 <td class="auto-style7" rowspan="1">                     <asp:textbox id="textboxusername" runat="server" width="240px"></asp:textbox>                 </td>                 <td rowspan="1">                     <asp:requiredfieldvalidator id="requiredusername" runat="server" controltovalidate="textboxusername" errormessage="please enter username." cssclass="validationerror"></asp:requiredfieldvalidator>                 </td>             </tr>             <tr>                 <td class="auto-style3" rowspan="1">email</td>                 <td class="auto-style6" rowspan="1">                     <asp:textbox id="textboxemail" runat="server" width="240px"></asp:textbox>                 </td>                 <td class="auto-style4" rowspan="1">                     <asp:requiredfieldvalidator id="requiredemail" runat="server" controltovalidate="textboxemail" errormessage="please enter emailaddress." cssclass="validationerror"></asp:requiredfieldvalidator>                 </td>             </tr>             <tr>                 <td class="auto-style2" rowspan="1">password</td>                 <td class="auto-style7" rowspan="1">                     <asp:textbox id="textboxpassword" runat="server" width="240px" textmode="password"></asp:textbox>                 </td>                 <td rowspan="1">                     <asp:requiredfieldvalidator id="requiredpassword" runat="server" controltovalidate="textboxpassword" errormessage="please enter password." cssclass="validationerror"></asp:requiredfieldvalidator>                 </td>             </tr>             <tr>                 <td class="auto-style2" rowspan="1">confirm password</td>                 <td class="auto-style7" rowspan="1">                     <asp:textbox id="textboxconfirmpassword" runat="server" width="240px" textmode="password"></asp:textbox>                 </td>                 <td rowspan="1">                      <asp:customvalidator id="requiredconfirmpassword" runat="server" controltovalidate="textboxconfirmpassword" errormessage="please confirm password." clientvalidationfunction="validateconfirmpassword" validateemptytext="true" cssclass="validationerror"></asp:customvalidator>                          </td>             </tr>             <tr>                 <td class="auto-style2" rowspan="1">country</td>                 <td class="auto-style7" rowspan="1">                     <asp:dropdownlist id="dropdownlistselectcountry" runat="server" height="16px" onselectedindexchanged="dropdownlist1_selectedindexchanged" width="240px">                         <asp:listitem>select country</asp:listitem>                         <asp:listitem>the netherlands</asp:listitem>                         <asp:listitem>belgium</asp:listitem>                         <asp:listitem>france</asp:listitem>                         <asp:listitem>germany</asp:listitem>                     </asp:dropdownlist>                 </td>                 <td rowspan="1">                     <asp:requiredfieldvalidator id="requiredcountry" runat="server" controltovalidate="dropdownlistselectcountry" errormessage="please select country." initialvalue="select country" cssclass="validationerror"></asp:requiredfieldvalidator>                 </td>             </tr>             <tr>                 <td class="auto-style2" rowspan="1">&nbsp;</td>                 <td class="auto-style7" rowspan="1">                     <asp:button id="submit" runat="server" text="button" />                 </td>                 <td rowspan="1">&nbsp;</td>             </tr>         </table>      </div>     </form>           <script type="text/javascript" src="scripts/customscripts.js"></script>  </body>  </html>
