Validate multiple valid emails separated by semicolon

Validate multiple valid emails separated by semicolon
There are various ways to validate them
1. Using custom validator and calling the javascript

<asp:CustomValidator ID="custValEmail" runat="server" ClientValidationFunction="validateMultipleEmailsCommaSeparated" ErrorMessage="Invalid email(s)"></asp:CustomValidator>

<script language="JavaScript" type="text/javascript">

function validateEmail(field)
{
     var regex=/^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
     var matchArray=field.match(regex);
     if(matchArray==null)
         return false;
     else
         return true;
}

function validateMultipleEmailsCommaSeparated(source, value)
{
     var result = document.getElementById("<%= txtEmail.ClientID %>").value.split(';');
     for(var i = 0;i < result.length;i++)
     {
         if(!validateEmail(result[i]))
         {
             value.IsValid = false;
             return false;
         }
     }
     value.IsValid = true;
}
</script>

2. Directly defining the regular expression in the RegularExpressionValidator control

    <asp:RegularExpressionValidator ID="s" runat="server" ControlToValidate="txtEmail" ErrorMessage="Invalid email(s)"
ValidationExpression="(([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)(\s*;\s*|\s*$))*"></asp:RegularExpressionValidator>

Calling Server side function using javascript

Every server-side method that is called from the client-side, must be declared as “static”, and also has to be decorated with the [System.Web.Services.WebMethod] tag.

Default.aspx

Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            txtId1.Attributes.Add("onblur", "javascript:CallMe('" + txtId1.ClientID + "', '" + txtContact1.ClientID + "')");
                    }
    }

[System.Web.Services.WebMethod]
    public static string Message(string str)
    {
        return str;
    }
[System.Web.Services.WebMethod]
    public static string GetContactName(string custid)
    {
        if (custid == null || custid.Length == 0)
            return String.Empty;
        SqlConnection conn = null;
        try
        {
            string connection = ConfigurationSettings.AppSettings["ConnectionString"];
            conn = new SqlConnection(connection);
            string sql = "Select sEmpFName from EMP_EmpPersonal where iEmployeeId = @CustID";
            SqlCommand cmd = new SqlCommand(sql, conn);
            cmd.Parameters.AddWithValue("CustID", custid);
            conn.Open();
            string contNm = Convert.ToString(cmd.ExecuteScalar());
            if (contNm.Length > 0)
                return contNm;
            else
                return "No record found.";
        }
        catch (SqlException ex)
        {
            return "error";
        }
        finally
        {
            conn.Close();
        }
    }
