更新：2007 年 11 月

根据指定用户的身份验证状态和角色成员资格，使用模板显示不同的内容。

<asp:LoginView
    EnableTheming="True|False"
    EnableViewState="True|False"
    ID="string"
    OnDataBinding="DataBinding event handler"
    OnDisposed="Disposed event handler"
    OnInit="Init event handler"
    OnLoad="Load event handler"
    OnPreRender="PreRender event handler"
    OnUnload="Unload event handler"
    OnViewChanged="ViewChanged event handler"
    OnViewChanging="ViewChanging event handler"
    runat="server"
    SkinID="string"
    Visible="True|False"
>
        <AnonymousTemplate>
            <!-- child controls -->
        </AnonymousTemplate>
        <LoggedInTemplate>
            <!-- child controls -->
        </LoggedInTemplate>
        <RoleGroups>
                <asp:RoleGroup
                    Roles="string"
                >
                        <ContentTemplate>
                            <!-- child controls -->
                        </ContentTemplate>
                </asp:RoleGroup>
        </RoleGroups>
</asp:LoginView>

备注

LoginView 控件根据不同用户的身份验证状态以及他们在通过身份验证后所属的网站角色，来显示不同的网站内容模板（或视图）。
