from the dataset
if you want the to do the same from the datagrid:

txtUsrName_pca.Text = dtg.Rows[i].Cells["CreditCardOwner"].Value.ToString();

// Cleaner less controll over the dictionary
private Dictionary<<string, double>> innerTable;
private Dictionary<<string, Dictionary<<string, double>>>> outterTable;

public DataAccessLayer()
{
  innerTable = new Dictionary<<string,double>>();
  outterTable = new Dictionary<<string, Dictionary<<string, double>>>>();

  innerTable.Add( "stringKey", 12312.012 );
  outterTable.Add( "anotherStringKey", innerTable );
}

// Longer but you'll define both dictionaries
// and how all the methods work.
public class UsingMyNewCollections
{
  // default constructor
  public UsingMyNewCollections()
  {
    InnerDictionary inner = new InnerDictionary();
    inner.Add( "StringKey", 1213.0123D );


    OutterDictionary outter = new OutterDictionary();
    batchTable.Add( "SomeKeyString", outter );
  }
