Default How to Display an Empty DataGrid on Page Load

I have created a DataGrid to accept inputs in textboxes in two TemplateColumns and display results after concatinating by clicking the concat button and showing the result in the results column. I just want to Display empty grid on Page Load first and accept inputs in textboxes and show Concat buttons. How can I do that? I am new to DataGrid and asp.net eventhandling but not new to programming. Following is the sample HTML that I am using. What should I do in Page_Load method?

<asp:datagrid id="DataGrid1" style="Z-INDEX: 101; LEFT: 288px; POSITION: absolute; TOP: 80px"
                runat="server" BackColor="Silver" ForeColor="Blue" Font-Size="Small" Font-Names="Courier New"
                HorizontalAlign="Center" AutoGenerateColumns="False" BorderColor="Blue" Visible = "True" >
                <EditItemStyle Font-Size="Small" Font-Names="Times New Roman" ForeColor="Red" BackColor="Silver"></EditItemStyle>
                <Columns>
                    <asp:TemplateColumn HeaderText="String1">
                        <EditItemTemplate>
                            <asp:TextBox id=TextBox1 runat="server" AutoPostBack="True">
                            </asp:TextBox>
                        </EditItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn HeaderText="String2">
                        <EditItemTemplate>
                            <asp:TextBox id=TextBox2 runat="server" AutoPostBack="True">
                            </asp:TextBox>
                        </EditItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn HeaderText="Concat Buttons">
                        <ItemTemplate>
                            <asp:Button ID="Button1" Runat="server" Text="Concatinate"></asp:Button>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn Visible="False" HeaderText="Result"></asp:TemplateColumn>
                </Columns>
            </asp:datagrid>

Logically, you can't display an empty grid. What is there to display?

You need to have at least 1 item bound to the grid for anything to show up, this item can result in all the inputs being empty, which would essentially amount to a new item.

What are you going to concat to? Other items in the grid (i.e are you trying to use the grid to build a list of items)?
