Answer 2

把Button的CommandArgument绑定数据为第一列的数据
点击按钮后触发GridView的RowCommand事件，在RowCommand事件里用e.CommondArgument可以取到第一列数据;
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
            DataSourceID="SqlDataSource1" onrowcommand="GridView1_RowCommand">
            <Columns>
                <asp:TemplateField ShowHeader="False">
                    <ItemTemplate>
                        <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" 
                            CommandArgument='<%# Eval("ID") %>' Text="查看"></asp:LinkButton>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <asp:GridView ID="GridView2" runat="server">
        </asp:GridView>取值代码：
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            TextBox1.Text = e.CommandArgument.ToString() ;
        }
