hi try this code:\
**Default.aspx code:**\

```
<asp:gridview ID="Gridview1" runat="server" ShowFooter="true" AutoGenerateColumns="false" onrowcreated="Gridview1_RowCreated" OnSelectedIndexChanged="Gridview1_SelectedIndexChanged">            <Columns>            <asp:BoundField DataField="RowNumber" HeaderText="Row Number" />            <asp:TemplateField HeaderText="Header
1">                <ItemTemplate>                    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>                </ItemTemplate>            </asp:TemplateField>            <asp:TemplateField HeaderText="Header
2">                <ItemTemplate>                    <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>                </ItemTemplate>            </asp:TemplateField>            <asp:TemplateField HeaderText="Header
3">                <ItemTemplate>                     <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>                </ItemTemplate>                <FooterStyle HorizontalAlign="Right" />                <FooterTemplate>                 <asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" onclick="ButtonAdd_Click" />                </FooterTemplate>            </asp:TemplateField>            </Columns>        </asp:gridview>
