Example
This example binds the DefaultSheetDataModel to a DataTable and the values of the IsColumnBound, IsEditable, IsEmpty and IsRowUsed are returned to a list box.
Private void Page_Load(object sender, System.EventArgs e)
{
  If (this.IsPostBack) Return;

  bool b, b1, b2, b3;
  DataTable dt = New DataTable("FarPoint");
  dt.Columns.Add("Product");
  dt.Rows.Add(New Object[] {"SpreadWebv2"});
  dt.Rows.Add(New Object[] {"InputPro for WinForms"});
  DataRow nrow;
  nrow = dt.NewRow();
  nrow["Product"] = "To Be Announced";
  dt.Rows.Add(nrow);
  dt.AcceptChanges();
  FarPoint.Web.Spread.Model.DefaultSheetDataModel dm = New FarPoint.Web.Spread.Model.DefaultSheetDataModel(dt);
  FpSpread1.ActiveSheetView.DataModel = dm;
  FpSpread1.ActiveSheetView.Columns[0].Width = 240;
  b = dm.IsColumnBound(0);
  b1 = dm.IsEditable(0,0);
  b2 = dm.IsEmpty();

  ListBox1.Items.Add(b.ToString());
  ListBox1.Items.Add(b1.ToString());
