Re: ValidatorCalloutExtender + CustomValidator - It´s possible?

If you still want to use a CustomValidator, then create a ClientValidationFunction instead of a server side function. The following demonstrates an example of this.

1    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" Title="Untitled Page" StylesheetTheme="SkinFile" %>
2    
3    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
4        
5    <html xmlns="http://www.w3.org/1999/xhtml" >
6        <head id="Head1" runat="server">
7            <title>Untitled Page</title>
8            <script type="text/javascript">
9               function ClientValidate(source, clientside_arguments)
10              {         
11                 if (clientside_arguments.Value == "janis" )
12                 {
13                    clientside_arguments.IsValid = true;
14                 }
15                 else { clientside_arguments.IsValid = false; }
16              }
17           </script>
18       </head>
19       <body>
20           <form id="form1" runat="server">
21               <asp:scriptmanager ID="Scriptmanager1" runat="server"></asp:scriptmanager>
22               <div>
23                   <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
24                   <asp:Button ID="Button1" runat="server" Text="Button" />
25                   <asp:CustomValidator ID="CustomValidator1" runat="server" Display="None" ErrorMessage="Error" 
26                       ControlToValidate="TextBox1" ClientValidationFunction="ClientValidate" />
27                   <ajaxToolkit:ValidatorCalloutExtender ID="ceUsuarioNome" TargetControlID="CustomValidator1" 
28                       runat="server" />
29               </div>
30           </form>

From what I've seen, you cannot use the ValidatorCalloutExtender when the CustomValidator is using a server side validation. In this case the solution is relatively simple. Instead of using a CustomValidator, try using a RegularExpressionValidator. I've tested the following at it will work with ValidatorCalloutExtender without a postback.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" Title="Untitled Page" StylesheetTheme="SkinFile" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    
<html xmlns="http://www.w3.org/1999/xhtml" >
    <head id="Head1" runat="server">
        <title>Untitled Page</title>
    </head>
    <body>
        <form id="form1" runat="server">
            <asp:scriptmanager ID="Scriptmanager1" runat="server"></asp:scriptmanager>
            <div>
                <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                <asp:Button ID="Button1" runat="server" Text="Button" />
                <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" 
                    ControlToValidate="TextBox1" Display="None" ErrorMessage="weadsasdsa" 
                    ValidationExpression="janis" />
                <ajaxToolkit:ValidatorCalloutExtender ID="ceUsuarioNome" 
                    TargetControlID="RegularExpressionValidator1" runat="server" />
   
            </div>
        </form>
    </body>

I believe, from looking at the ValidatorCallout known issues, that it only works on CustomValidators with client-side validation (i.e., JavaScript). Here's the part of the sentence:

"...will only work for custom validators which utilize client-side validation."
