管理用户角色-是否需要多个LoginView来控制更多按钮 [英] Managing user roles - is there a need for more than one LoginView in order to control more buttons

问题描述

我创建了一个LoginView，以使一个按钮对普通用户(即非管理员)隐藏.效果很好，但是当我尝试添加另外两个按钮-FileUploadControl和Upload按钮时，出现错误消息FileUpload1不存在.它肯定存在，我不明白为什么会抱怨...

I created a LoginView in order to keep one button hidden from normal users, i.e not admins. Works great but when I tried to add two more buttons - FileUploadControl and Upload button, I get an error that FileUpload1 does not exist. It definitely exists and I don't get why it complains...

我需要另一个LoginView还是该怎么做?

Do I need another LoginView or how can I do it?

谢谢

推荐答案

我怀疑您试图像自然地那样直接从后面的代码访问控件.

I suspect that you are trying to access the controls directly from the code behind as you would naturally do.

例如

在.aspx页面上

<asp:FileUpload id="fileUpload1" runat="server" />

在后面的代码中

 string fileName = fileUploadl.FileName;

但是，当控件位于 LoginView 中时，不能直接访问控件.您需要执行以下操作.因此，如果您拥有这样的控件.

However, you cannot access controls directly when they are within the LoginView. You need to do the following. So if you had the control like this.

<asp:LoginView id="LoginView1" runat="server">
    <AnonymousTemplate>
        <asp:FileUpload ID="fileUpload1" runat="server" />
    </AnonymousTemplate>
</asp:LoginView>

您可以像这样访问fileUpload1控件

You can access the fileUpload1 control like this

 FileUpload fileUpload1 = (FileUpload) LoginView1.FindControl("fileUpload1");

然后，您可以访问 fileUpload1 属性.

Then you can access the fileUpload1 properties.
