自定义CreateUserWizard 控件

最近的项目里要做一些维护，以前用的是CreateUserWizard ，结果发现里面的验证功能不够，在把创建的用户信息导入到别的表里的时候，经常会有长度的问题。或者，密码长度超出128位，用户会创建失败，但返回的信息不够友好。所以需要做一些自定义，来增强相关的功能。

<asp:CreateUserWizard ID="CreateUserWizard1" Runat="server">
  <WizardSteps>
    <asp:CreateUserWizardStep runat="server">
    </asp:CreateUserWizardStep>
    <asp:CompleteWizardStep runat="server">
    </asp:CompleteWizardStep>
  </WizardSteps>
</asp:CreateUserWizard>

这个是插入CreateUserWizard以后的状况。

做一些定制化

<asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
    <ContentTemplate>
        <table border="0" style="font-size: 100%; font-family: Verdana" mce_style="font-size: 100%; font-family: Verdana">
            <tr>
                <td align="center" colspan="2" style="font-weight: bold; color: white; background-color: #5d7b9d" mce_style="font-weight: bold; color: white; background-color: #5d7b9d">
                    Sign Up for Your New Account</td>
            </tr>
            <tr>
                <td align="right">
                    <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">

    </ContentTemplate>
</asp:CreateUserWizardStep>

这个也是MSDN里面的内容，定制好了，跑一下。

不行，验证都没起作用啊。

如果是一般自己做的网页，button的CausesValidation会设为true来验证页面输入。这个页面上也有button，怎么才能把它找出来呢？

这也需要自定义。

点击页面上CreateUserWizard旁边的小箭头，选择Convert to CustomNavigationTemplate，生成代码如下

这段代码放在CreateUserWizardStep里，就可以做到定制button了。

再来，OK，再提交要先过验证了。

总结：实现CreateUserWizard中button的自定义是关键
