Remarks
DevExpress Reporting
You can pass report parameters to the Fill
method, as the following code snippet demonstrates:
using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
// ...
var report = new XtraReport1();
SqlDataSource ds = new SqlDataSource();
ds.ConnectionName = "connection1";
ds.ConnectionParameters = new MsSqlConnectionParameters(".", "NORTHWND", "sa", "dx", MsSqlAuthorizationType.SqlServer);
DevExpress.DataAccess.Sql.StoredProcQuery spQuery = new StoredProcQuery("SalesByCategory", "SalesByCategory");
spQuery.Parameters.Add(new QueryParameter("@CategoryName", typeof(DevExpress.DataAccess.Expression), new DevExpress.DataAccess.Expression("?p1", typeof(string))));
spQuery.Parameters.Add(new QueryParameter("@OrdYear", typeof(string), "2000"));
ds.Queries.Add(spQuery);
DevExpress.XtraReports.Parameters.Parameter p1 = new DevExpress.XtraReports.Parameters.Parameter();
p1.Name = "p1";
p1.Type = typeof(string);
p1.Value = "Seafood";
report.Parameters.Add(p1);
report.DataSource = ds;
report.DataMember = "SalesByCategory";
ds.Fill(new DevExpress.XtraReports.Parameters.Parameter[] { p1 });
Method Execution Workflow
If errors occur during data connection, a DatabaseConnectionException is thrown.
All queries are validated one by one. When validation errors occur, they are collected and returned by throwing a AggregateException. Use its InnerExceptions property to access a collection of QueryExecutionException objects (use their InnerException property to access an actual ValidationException).
If the validation succeeds, all queries are executed one by one. If any errors occur during the execution of each query, these errors are collected and returned by throwing a AggregateException. Use its InnerExceptions property to access a collection of QueryExecutionException objects (use their InnerException property to access an actual DevExpress.DataAccess.Native.Sql.SqlExecutionException).
To validate and execute only specific queries, use a corresponding Fill method overload with the queriesToFill parameter.
