在 GridView 中选择一行，并将记录 ID 传递到重定向的页面

我已经为这个问题苦苦挣扎了一整天，但我似乎没有找到答案。

我有一个名为PickRecord的页面.aspx其中我动态生成了"开始面试"，"编辑"和"查看记录"列，这些列将相应地将我重定向到StartInterview.aspx或EditView.aspx Interview。

PickRecord.aspx - GridView 填充了受访者姓名，并生成了一个按钮，单击该按钮时应将我重定向到 StartInterview.aspx并在所选记录中为我提供其他字段/信息。

StartInterview.aspx - 包含有关所选记录的其他信息，这些信息需要使用数据库中的数据进行填充。我尝试过查询字符串，使用selectedIndexChanged，但没有运气。

如果有人能指导我完成这个，我们将不胜感激。提前感谢！

PickRecord.aspx

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Height="470px" Width="660px" HorizontalAlign="Center" SelectedIndexChanged="GridView1_SelectedIndexChanged">
    <Columns>   
        <asp:BoundField DataField="First_Name" HeaderText="First Name" ItemStyle-HorizontalAlign = "Center">    
        </asp:BoundField>   
        <asp:BoundField DataField="Last_Name" HeaderText=" Last Name" ItemStyle-HorizontalAlign = "Center" >    
        </asp:BoundField>   
        <asp:BoundField DataField="Salon_Number" HeaderText="Salon" ItemStyle-HorizontalAlign = "Center" >  
        </asp:BoundField>   
    </Columns>
