Bom dia amigo, faça o seguinte:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="RequiredFieldVisual.aspx.cs" Inherits="JQTest.RequiredFieldVisual" %>
<!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 runat="server">
<title></title>
<style type="text/css">
.estiloErros ul li
{
padding:0 0 10px 0;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
Nome: <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
Telefone: <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ControlToValidate="TextBox2" ErrorMessage="Obrigatorio" Text="*" ></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="TextBox1" ErrorMessage="Obrigatorio" Text="*" ></asp:RequiredFieldValidator>
<asp:Button ID="Button1" runat="server" Text="Button" />
<br />
<asp:ValidationSummary ID="ValidationSummary1" runat="server" CssClass="estiloErros"/>
</div>
</form>
</body>
</html>
Com o CssClass modifiquei o espaço abaixo de cada linha do summary. :)
