Question by Scenario

Hi,

My questions are how to apply the telerik Reporting with this Scenario.

• We are developing the web application
• We have 2 database servers development Database server and Production Database server
• During development we will use the development database server when we deploy to Production will copy the website and change the connection string in web.config
• Our developer able to design the report and preview in design time with the correct layout
• After deploy the web application our developer don't have to change the database connection in the report manually it will use the connection string in web.config

After we try we got the problems below;

• we can't preview the report if we using the connection string from the web.config have to use the wizard to generate the connection for us
• if we use the wizard we don't know how to change the connection string manual at runtime
• we need to recompile everything after change the connection string in the report when want to deploy to production server

The current solution

• we are manual create the connection string by hardcode "see Code #1" it's give us the preview on design time

• At runtime we rebind the data manual by take the connection string from web.config "see Code #2"  it's give us don't have to recompile the project when deploy to the server

below are the current source code we are using for the moment

    public partial class Report1 : Telerik.Reporting.Report
    {
        public Report1()
        {
            /// <summary>
            /// Required for telerik Reporting designer support
            /// </summary>
            InitializeComponent();

            sqlSelectCommand1 = new System.Data.SqlClient.SqlCommand();
            sqlDataAdapter1 = new System.Data.SqlClient.SqlDataAdapter();
            sqlConnection1 = new System.Data.SqlClient.SqlConnection();
            sqlConnection1.ConnectionString =
                "Data Source=Develop_telerik;Initial Catalog=insurance;Persist Security Info=True;User ID=sa;Password=rYnI@6%33$3kdnOOk";

            sqlSelectCommand1.CommandText = "SELECT * FROM TelerikReport";
            sqlSelectCommand1.Connection = sqlConnection1;
            sqlDataAdapter1.SelectCommand = sqlSelectCommand1;
            this.DataSource = sqlDataAdapter1;

        }
    }
}

[Code #1]


above the code inside the report
It's gave us the preview in design time

         System.Data.SqlClient.SqlCommand sqlSelectCommand1;
         System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
         System.Data.SqlClient.SqlConnection sqlConnection1;
         Report1 _report1 = new Report1();

         sqlSelectCommand1 = new System.Data.SqlClient.SqlCommand();
         sqlDataAdapter1 = new System.Data.SqlClient.SqlDataAdapter();
         sqlConnection1 = new System.Data.SqlClient.SqlConnection();
         sqlConnection1.ConnectionString = ConfigurationManager.ConnectionStrings["TelerikConnectionString"].ToString();

         sqlSelectCommand1.CommandText = "SELECT * FROM TelerikReport";
         sqlSelectCommand1.Connection = sqlConnection1;
         sqlDataAdapter1.SelectCommand = sqlSelectCommand1;

         _report1.DataSource = sqlDataAdapter1;

         ReportViewer1.Report = new Report1();

[Code #2]


above are the code in the ReportView page








Any ideas, to improve the development time or anyone has the sample project like this.
