How to add blank row in grid view?

问题

I am new to the ASP.NET i am binding one list of data object to the grid view. I want to display blank row after each record in grid view so i have done this by as below in code behind

List<DatabaseDTO> lstdatabase= new List<DatabaseDTO>();
foreach(int jobNumber in JobnumberList)
{
    DatabaseDTO dataObject = new DatabaseDTO();
    dataobject = GetDatabaseData(jobNumber);//Method to retrieve data and return data object 
    lstdatabase.Add(dataObject);
    lstdatabase.Add(new DatabaseDTO());
}
 gridView.DataSource = lstdatabase;
 gridView.DataBind();

it's working correct i am getting the desired blank row in the grid view but i know this is not right way because i am adding object to the list so i can add the blank row in place of that i would very much like to adjust this blank row from the aspx page. I know there is another way using the DataTable but it is also not very good because it also adds the unnecessary records to the DataTable. So any other work around or way to solve this would be very great. Thank you.

Try This

<div>
<asp:DataList ID="DataList1" runat="server">
    <ItemStyle ForeColor="#4A3C8C" BackColor="#E7E7FF"></ItemStyle>
    <HeaderTemplate>
        <table width="900px">
            <tr>
                <td width="300px">
                    <b>Name</b>
                </td>
                <td width="300px">
                    <b>Account No</b>
                </td>
                <td width="300px">
                    <b>Company</b>
                </td>
            </tr>
        </table>
    </HeaderTemplate>
    <ItemTemplate>
        <table width="900px">

You can't have an empty row in the Datagrid if it isn't present in the data source. You have to think that after all the grid data is just a representation of your data source, if there is a empty row, the grid will show it, if there is not, it wont.

Write a stored procedure to get Output Parameter from sql server and bind to grid view if record is not there..
