如何让RequiredFieldValidator提示错误的同时弹出对话框

[lyp524]

一个表单很长，正常RequiredFieldValidator提示错误不容易被发现，能不能在RequiredFieldValidator提示错误的同时，弹出个对话框“有未填选项”。

用js写验证啊

用验证控件就可以搞定了：
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1"
Display="Dynamic" ErrorMessage="TextBox1不能为空"></asp:RequiredFieldValidator>
<br />
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="TextBox2"
Display="Dynamic" ErrorMessage="TextBox2不能为空"></asp:RequiredFieldValidator>
<br />
<asp:ValidationSummary ID="ValidationSummary1" runat="server"
ShowMessageBox="True" ShowSummary="False" />
<br />
<asp:Button ID="Button1" runat="server" Text="确定" />
</div>
