If I remember correctly, DataGridView has a .Rows.Add property, like this:

dataGridView.Rows.Add  

and

dataGridView.Rows.Insert

You should convert your data into an array first.
Take a look here: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.rows.aspx

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "createNewRecord")
    {
             //Another Gridview will be created here, and it will contains EditTemplate.
             //you can use that gridview to receive data by Edit.
    }
}

Sample of Edit tamplate gridview

<Columns>
    <asp:TemplateField>
    <EditItemTemplate><asp:textboxt id="txt1" runat="server" /></EditItemTemplate>
    </asp:TemplateField>
    </Columns>
