Hi Expert!,

I have few asp:textbox with requiredfield validator bind on different validation group and different button into the same page.

What i need is when user click on button1
 1) First validate controls over asp.net validator for the specific group.
 2) Then if no error, call a javascript method (who call webservices) and wait for response
 3) No server event postback should occur cause i'm waiting for webservice response.

All the webservices jobsworks fine. My problem now is I need to add "RequiredFieldValidator" on some  controls and i can't find how to call the validation by javascript like the asp:button does.

Anybody can help?

In your JavaScript, call this function:
ValidatorEnable(val, true);
val: the validator ID.
If you need to trigger several validators, then you have to call the above functions several times: one validator at a time.

Perfect!!! I also found that "ValidatorValidate" do the same jobs.

Below is a complete exemple base on Prairiedog solution :)

Thanks Sage Prairiedog!!
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
 
    <script language="javascript" type="text/javascript">
        function CustomFormValidation()
        {   
            //Simly use ValidatorValidate or ValidatorEnable
            var aspxCtrl = document.getElementById("<%= reqFdlUser.ClientID %>");
            ValidatorEnable(aspxCtrl);
            if(!aspxCtrl.isvalid)
                return false;
                
            aspxCtrl = document.getElementById("<%= reqFdlPass.ClientID %>");
            ValidatorValidate(aspxCtrl);
            if(!aspxCtrl.isvalid)
                return false;                
                
            return true;
        }
    </script>    
</head>
 
<body>
    <form id="form1" runat="server">
    <div>
            <asp:TextBox ID="txtMUser" runat="server"></asp:TextBox><br />
            <asp:TextBox ID="txtMPass" runat="server"></asp:TextBox><br />
            <asp:RequiredFieldValidator ControlToValidate="txtMUser" ID="reqFdlUser" runat="server" ErrorMessage="RequiredFieldValidator" Display="Dynamic"></asp:RequiredFieldValidator>
            <asp:RequiredFieldValidator ControlToValidate="txtMPass" ID="reqFdlPass" runat="server" ErrorMessage="RequiredFieldValidator" Display="Dynamic"></asp:RequiredFieldValidator>
            <input id="btnTest" onclick="if(CustomFormValidation())alert('Form is valid');" type="button" value="Register"/>
    </div>
    </form>
</body>
</html>

Solution for validate a specific group without having to work with the "clientid".

Here is a function i've just create in javascript which you can pass a validationgroupname and it returns true or false depends if the validation is correct!!

ENJOY!!! :)

        function ValidateCtrlByGroup(psValidationGroupName)
        {   
            var bResult = true;
            for(i=0;i < Page_Validators.length; i++){
                ctrlValidator = Page_Validators[i];
                if(psValidationGroupName == ctrlValidator.validationGroup){
                    ValidatorEnable(ctrlValidator);        
                    if(!ctrlValidator.isvalid)
                        bResult = false;
                }
            }
            return bResult;
        }
