推荐答案

为什么不使用CompareValidator?

<table border="0" bgcolor="#b0c4de">
   <tr valign="top">
     <td colspan="4"><h4>Compare two values</h4></td>
   </tr>
   <tr valign="top">
     <td><asp:TextBox id="txt1" runat="server" /></td>
     <td> = </td>
     <td><asp:TextBox id="txt2" runat="server" /></td>
     <td><asp:Button Text="Validate" runat="server" /></td>
   </tr>
</table>
<br />
<asp:CompareValidator

id="compval"

Display="dynamic"

ControlToValidate="txt1"

ControlToCompare="txt2"

ForeColor="red"

BackColor="yellow"

Type="String"

EnableClientScript="false"

Text="Validation Failed!"

runat="server" />

您可以使用比较验证器，并将controltocompare设置为密码文本框的ID，将controltovalidate设置为确认密码文本框的ID.运算符应相等或类似.

you can use compare validator and set the controltocompare as the id of the password textbox and controltovalidate as the id of the confirm password textbox. operator should be equal or something similar.
