What's the error message? Include the error message in your question always. It will save our time.

Move the declaration of "dTable" outside the try block:

private DataTable BindGrid()
      {
        PersonBAL3 p = new PersonBAL3();
        DataTable dTable = null;
        try
        {
          dTable = p.Load();
          GridView1.DataSource = dTable;
          GridView1.DataBind();
        }
        catch (Exception ee)
        {
          lblMessage.Text = ee.Message.ToString();
        }
        finally
        {
          p = null;
        }
        return dTable;
     }
