Is it possible hand a report a list to bind to?

[Timothy]

Ideally, I would like to do accomplish the following:

IEnumerable<MyPoco> pocos = _reportingTasks.GetMyPocos();

 var report = new MyPocoReport {DataSource = pocos};

ReportViewer1.ReportSource = new InstanceReportSource {ReportDocument = report};

Basically, because of how are dependencies are set up, I would like to hand my report a pre-populated list rather than setting the DataSource and DataMember properties on the objectDataSource and letting the report execute my query.  All the examples I have found either perform data access in the DataSource object or pre-populate a collection in the constructor (like the List Bound report demo).  Any thoughts?

Hello Timothy,

If I have understood you correctly what you want to do is this:

var myList= SomeMethodThatReturnsList();

var ds = new ObjectDataSource
  {
    DataSource = myList
  };

var report1 = new Report1();
report1.DataSource = ds;

this.viewer1.ReportSource = new InstanceReportSource { ReportDocument = report1 };

Please note that the DataSource of the report cannot be a simple list or IEnumerable for example - it has to be one of the following types: Entity, Object, SQL, Cube or Open Access data source.

All the best,

Just to be clear, are you saying your code example  works?

Hi Timothy,

Yes the example is runnable, you will have only to assign DataMember as well if the class you are using is not a data class and you are relying on a method in it that returns data. But having in mind your code from the previous ticket, the proposed snippet will be enough.
