Crystal Report Binding With Parameters From C#

This script can be used when you want to bind a Crystal Report with Stored Procedure and want to pass some parameters to the report. These parameters can be in SubReport also. The parameters get assigned for the respective subreports and main report if the Parameter name differs.

The major use of this code is it would not ask for the login details while showing the report. The Login details are set based on the App.Config connection which is Global across the Application.


TableLogOnInfos myTableLogOnInfos = new TableLogOnInfos();
TableLogOnInfo myTableLogOnInfo = new TableLogOnInfo();
ConnectionInfo myConnectionInfo = new ConnectionInfo();

//Set Database Connection Details
string[] arrConn = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"].Split(';');

for (int i = 0; i < arrConn.Length; i++)
{
string[] arrServer = arrConn[i].Split('=');
if (arrServer[0].ToLower().Trim() == "server" || arrServer[0].ToLower().Trim() == "data source")
myConnectionInfo.ServerName = arrServer[1];
if (arrServer[0].ToLower().Trim() == "database" || arrServer[0].ToLower().Trim() == "initial catalog")
myConnectionInfo.DatabaseName = arrServer[1];
if (arrServer[0].ToLower().Trim() == "userId" || arrServer[0].ToLower().Trim() == "user id")
myConnectionInfo.UserID = arrServer[1];
if (arrServer[0].ToLower().Trim() == "Password" || arrServer[0].ToLower().Trim() == "pwd")
myConnectionInfo.Password = arrServer[1];
}

//This Code is used to Get the Reportname based on the namespace. This code can be used globally across the application. If you can pass the Report Name directly then this piece of code wont be necessary
