Getting data from table as

{
        string query = "SELECT * FROM LeafShape";

        try
        {
            return SqlHelper.ExecuteDataset(con, CommandType.Text, query);               
        }
        catch (SqlException ex)
        {
            throw ex;
        }
        catch (Exception ex)
