Client Side Validation with CustomValidator using JQuery

Hi all,

try this example for Client Side Validation with CustomValidator using JQuery

1) Open VS2008 and create a new website and add new web page

2) From Toolbox drag Text-box and CustomValidator controls

Enter Code :
 <asp:TextBox ID="TextBoxCode" runat="server" Width="195px"></asp:TextBox>
 <asp:CustomValidator ID="CustomValidator6" runat="server" ControlToValidate="TextBoxCode"
 ErrorMessage="This code already exists Please enter another one."
 ForeColor="Red" ValidationGroup="InsertUpdate"
 <br />
 <asp:Button ID="Button1" runat="server" Text="Save" ValidationGroup="InsertUpdate"/>

3) In code behind add the following code

 public static bool IsUnique(string code)
 return false;

4) Add this JavaScript to validate CustomValidator using Client Side

<script type="text/javascript">
 function CheckUniqueness(src, args) {
 var isValid;
 type: "POST",
 url: "Default.aspx/IsUnique",
 data: "{'code': '" + args + "'}",
 contentType: "application/json; charset=utf-8",
 dataType: "json",
 async: false,
 success: function(msg) {
 isValid = msg.d;
 args.IsValid = isValid;

after that run your page

Hope this helps

Good Luck.
