通过CreateUserWizard进行用户注册之前，请检查某些条件 [英] Check certain condition before user-registration through CreateUserWizard

问题描述

我有一个RadioButtonList和一个CreateUzerWizard.
当用户单击创建用户"向导的创建用户"按钮时，
首先必须确定用户是否选择了任何单选按钮
如果没有，请停止创建用户操作

I have a RadioButtonList and a CreateUzerWizard.
When user click on the createte-user Button of Create-User wizard,
first It has to varify whether user has selected any radio-button
if no stop the create-user action

protected void CreateUserWizard1_CreatingUser(object sender, LoginCancelEventArgs e)
    {        
        if (RadioButtonList1.SelectedIndex == -1)
        { return;//not to proceed             
        }
    }

但是尽管用户未选择单选按钮，但仍在进行创建用户操作.此时如何防止创建用户操作.
感谢您提前提供帮助.

But still though user not select the radiobutton create-user action is taking place. How can I prevent the create-user action at this point.
Thanks for help in advance

推荐答案

添加一行:

Add a line:

protected void CreateUserWizard1_CreatingUser(object sender, LoginCancelEventArgs e)
    {
        if (RadioButtonList1.SelectedIndex == -1)
        { 
            e.Cancel=true;  // <----- Add this line.
            return;//not to proceed
        }
    }
