public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        this.Title = "验证控件综合使用";
        username.Focus();
    }
    protected void valxusername_ServerValidate(object source, ServerValidateEventArgs args)
    {
        args.IsValid = true;
        if(username.Text==""){            valxusername.ErrorMessage = "用户名不能为空！";
            args.IsValid = false;
        }
    }
    protected void valxpassword_ServerValidate(object source, ServerValidateEventArgs args)
    {
        args.IsValid = true;
        if (password.Text.Length<3 || password.Text.Length>6)
        {
            valxpassword.ErrorMessage = "密码长度为3-6之间！";
            args.IsValid = false;
        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
            if(Page.IsValid){                 Label1.Text="验证通过";
            
            }else{                Label1.Text = "验证不通过";
            }
    }
}
现在，确认密码的错误提示信息可以由ValidationSummary显示，但是两个用户定义验证控件的错误提示信息不能在ValidationSummary中显示，如何才能显示呢？

    楼主的这种编写是大有问题的!!
    用asp.net验证控件的好处可以做到不写服务端代码滴!
    而楼主验证非空都在服务端,所以你根本没在用asp.net验证控件!!
    我给楼主一段验证非空的代码,其他楼主可参照做!!
