Question

我有一个Gridview，它通过sqlDataSource显示联系人列表。

包含用于删除记录的项目模板 - 一个LinkButton - OnClientClick设置为使用一些JavaScript：“return confirm（'你确定要删除这个用户吗？'）;”这样，用户可以弹出一个“是”或“取消”选项。

当从Contact表中删除用户时，我还需要使用Membership.DeleteUser（UserName，true）语句删除AspNet Membership表中的同一用户。

Membership表的 Contact.IntranetUserName 列和 UserName 包含相同的数据值，因此方便了。

不知道要使用什么事件，我开始使用Gridview的OnRowCommand - 但无法弄清楚如何获取被删除行的“IntranetUserName”列的值（通过联系表中的项模板）并将其传递给Membership.DeleteUser语句。

任何关于此的 C＃想法都会非常感激。也许我应该使用GridView的OnRowDeleted或OnRowDeleting代替？或者也许是LinkButtons OnCommand？

GridView和SqlDataSource：

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ContactID" 
                    DataSourceID="SqlDataSource2" Width="738px" OnRowCommand="deleteFromAspnetProvider" >
                    <Columns>
                        <asp:TemplateField ShowHeader="False">
                            <ItemTemplate>
                                <asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="return confirm('Are you sure you want to delete this user?');" 
                                    CommandName="Delete" Text="Delete User"></asp:LinkButton>
                            </ItemTemplate>
                        </asp:TemplateField>

Answer 1

请尝试使用RowDeleting事件。

void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
  string name = e.Values["IntranetUserName"] as string;
}

PS：我没有在这台机器上安装VS，所以我不能自己测试它...抱歉。
