Question

我使用删除和编辑链接按钮创建了GridView来执行编辑和删除操作。这适用于编辑按钮，但不适用于删除按钮。有什么问题？

当我运行我的应用程序时，它给了我这个错误：

必须声明标量变量“@UserName”

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
DataSourceID="SqlDataSource1">
<Columns>
<asp:CheckBoxField DataField="IsApproved" HeaderText="IsApproved"

<asp:BoundField DataField="UserName" HeaderText="UserName" 
SortExpression="UserName" />
<asp:CheckBoxField DataField="IsLockedOut" HeaderText="IsLockedOut" 
SortExpression="IsLockedOut" />
<asp:CommandField ShowEditButton="True" ShowDeleteButton="True" />
</Columns>
</asp:GridView>

DeleteCommand="DELETE FROM [vw_aspnet_MembershipUsers] WHERE (UserName = @UserName)">
<UpdateParameters>

<DeleteParameters>

</asp:SqlDataSource>

Answer 1

您应该通过Membership.DeleteUser(user.UserName)或通过存储过程[dbo].[aspnet_Users_DeleteUser]

删除

Answer 2

我的建议是处理SQLDataSource的“删除”事件。调用asp.net成员资格api从后面的代码中删除。

确保导入System.Web.Security，然后尝试以下操作：

    // Delete Membership User 
    Membership.DeleteUser(UserName);

无论如何，从视图中删除记录并不是最好的方法。

从会员资格中删除用户
