Remarks
The code sample below shows how to use IConnectionConfigProvider to provide a custom configuration file with connection strings. The sample assumes that you have an Entity Framework data model named NorthwindEntities that describes data fields. The code creates a new EFDataSource and assigns it as a data source for XtraReport1.
using DevExpress.Data.Entity;
using DevExpress.DataAccess.EntityFramework;
// ...
class EFConnectionConfig : IConnectionConfigProvider, IConnectionStringsProvider {
public IConnectionStringInfo[] GetConfigFileConnections() {
throw new NotImplementedException();
}
public string GetConnectionConfigPath() {
// Return the path to custom configuration file
return Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "efConnectionStrings.config"); ;
}
public IConnectionStringInfo[] GetConnections() {
throw new NotImplementedException();
}
public string GetConnectionString(string connectionStringName) {
throw new NotImplementedException();
}
public IConnectionStringInfo GetConnectionStringInfo(string connectionStringName) {
throw new NotImplementedException();
}
}
public class EFConnection {
public void ConfigureDataSource() {
// Create a report instance
var xtraReport1 = new DevExpress.Examples.CoreLibraries.XtraReport();
// Create an EFDataSource
var dataSource = new EFDataSource();
dataSource.ConnectionParameters = new EFConnectionParameters(typeof(NorthwindEntities));
// Set the report's data source
xtraReport1.DataSource = dataSource;
xtraReport1.DataMember = "Products";
var reportDesignTool = new ReportDesignTool(xtraReport1);
// Register the interface as a service
reportDesignTool.DesignForm.DesignMdiController.AddService(typeof(IConnectionStringsProvider), new EFConnectionConfig());
reportDesignTool.ShowDesigner();
}
}
