动态添加

Question

有一个gridview，如下：
<asp:GridView ID="GridView1" runat="server" Width="100%" AutoGenerateColumns="False" OnRowCommand="GridView1_RowCommand" AllowPaging="True" PageSize="5" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowDataBound="GridView1_RowDataBound">
                                    <HeaderStyle CssClass="subHeader" />
                                    <Columns>
                                                                                                                                                        <asp:TemplateField HeaderText="操作">
                                            <ItemTemplate>
                                            <asp:Button ID="btnOut" runat="server" CommandName="Out" CommandArgument="<%#Container.DataItemIndex %>" Text="呼出" />
                                             </ItemTemplate>
                                            <ItemStyle HorizontalAlign="Center" />
                                        </asp:TemplateField>
                                    </Columns>
                  </asp:GridView>
当我点击这个按钮时获取某列值，根据这个值在表格里动态添加一行，并且将数据显示显示出来（如果有多行就添加多行）
请问下该怎样做。

Answer 1

dt = (DataTable )ViewState["dt"];
DataRow dr = dt.NewRow();
dr["Name"] = "";
dt.Rows.Add(dr);
BindData();
ViewState["dt"] = dt;
