Adding Multiple rows to GridView

[deadalous]

hi,
I am having a scenario,where i am using GridView + Dataset as datasource + .NET2.0 + VB.NET 2005.
I need to add more rows on runtime to GridView so
i need to first read the data from dataset and fill my GridView and then have an Add button which adds a new row on click ( for each column).
here is what i've done:
i just added a textbox in <ItemTemplate> for each <TemplateField> column

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Style="z-index: 106;
            left: 40px; position: absolute; top: 188px" CellPadding="4" ForeColor="#333333" GridLines="None">
<Columns>
                <asp:TemplateField HeaderText="Milestone">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Planned date">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Actual Date">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="% Complete">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Progress Date">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox5" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Comments">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox6" runat="server"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
            
            </Columns>
            
        </asp:GridView>

I would imagine this is going to require some client-side JavaScript but I don't know how that'll interface with your GridView unless you're using ASP.Net AJAX and an Update Panel.

I do want to say that you, sir, are a shinning example of how people should describe their questions / issues. I love the gif!
