Question

Like you Know the easier way to fill a dataset is with a dataAdapter like this :
DataSetEmp myDataSet = new DataSetEmp();
…(here Id did a select request..)

SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = myCommand1;
adapter.Fill(myDataSet.myDataTable1);

AND
……(here Id did a select request..)

 SqlDataAdapter adapter2 = new SqlDataAdapter();
  adapter2.SelectCommand = myCommand2;
  adapter2.Fill(myDataSet.myDataTable2);

//I have a Crystal report

CrystalReport1 report1 = new CrystalReport1();
report1.setDataSource(myDataSet);

This Way works perfectly good, but I want to fill data with DataReader not DataAdapter because I want to Check some values In a while(myReader.read()){ ….} loops.

Answer 1

You have to populate the DataTable manually using its methods and properties. Eg. creating each contained DataTable in turn (in essence re-creating the implementation of DataAdapter.Fill).

Alternately you could use the DataAdapter and before passing it to Crystal Reports use those same members to modify the DataTable‘s content.
