问题描述

这是asha bhatt.
请看我的代码.
我在asp.net Web应用程序中有radiobuttonlist和checkboxlist以及一个Submit按钮.

使用System.Data.SqlClient;

公共局部类Default3:System.Web.UI.Page
{
字符串scon =数据源= RBWORKSTATION2 \\ SQLEXPRESS;初始目录= onlineexamdb;集成安全性= True; MultipleActiveResultSets = true";
SqlConnection con;
SqlDataAdapter da;
SqlCommand cmd;
数据集ds;
//静态DataTable dt;
静态DataTable dt = new DataTable();
SqlDataReader readsid，readalltest，readallinterview，readallquestion;
IDataReader readqus;
公共字符串qus，sid，alltest，allinterview，评分；
int [] allquestion = new int [3];
静态整数计数= 0;
RadioButtonList rdlist = new RadioButtonList();
CheckBoxList chklist = new CheckBoxList();
ListItem li1 = new ListItem();
ListItem li2 = new ListItem();
ListItem li3 = new ListItem();
ListItem li4 = new ListItem();
bool flage = false;

受保护的void Page_Load(对象发送者，EventArgs e)
{
如果(！IsPostBack)
{
con =新的SqlConnection(scon);
con.Open();
cmd = new SqlCommand(从TestInfo中选择SubID，其中TestID =(从TestInfo中选择MAX(TestID))；"，con);
readsid = cmd.ExecuteReader();
while(readsid.Read())
{
sid = readsid [0] .ToString();
//Response.Write(sid);
}
cmd = new SqlCommand("SELECT QusID，Question，Option1，Option2，Option3，Option4，NumberofCorrectAnswers，CorrectOptions来自问题" INNER JOIN SubjectInfo ON Questions.SubID = SubjectInfo.SubID其中Questions.SubID =" + sid +"，con);
readqus = cmd.ExecuteReader();
如果(readqus！= null)
{
dt.Load(readqus);
}
con.Close();

createquestion();
}
}

受保护的void SubmitButton_Click(对象发送者，EventArgs e)
{

}
}

                }
            }
        return "done";
    }

在验证功能中，当我的标志不相等时，我想显示一个带有是"和否"按钮的消息框.
但是如何创建消息框.

In validation function when my flage is not equcl that time i want to show one message box with yes and no button .
but how can i create messagebox.
Plz telll me.

推荐答案

最好使用是"/否"按钮创建"DIV"运行时并显示它.但是为此，您必须使用Java脚本.

It''s better to create a "DIV" run time with "Yes"/"No" buttons and display it. But for that you have to use Java Script.
