推荐答案

你好，





我看到了您给出的报告屏幕截图但是它没什么，如果您可以运行应用程序，它会询问每次数据库登录凭据数据库名称，用户名和密码。我们可以轻松解决请求登录凭据。如果你可以使用下面的代码

Hi,


I saw the report screen shot above you gave but it is nothing, if you can run the application it will ask every time database login credentials database name, user name and password. we can easily solve asking login credentials. if you can use the below code

ReportDocument reportDocument= new ReportDocument();

reportDocument.Load(Server.MapPath("Reports\\CustomerReport.rpt"));

reportDocument.SetDatabaseLogon(db username, db password, db server, database name);

CrystalReportViewer1.ReportSource = reportDocument;
