与asp超链接控件的可见性有关的问题 [英] Problem Related to asp Hyperlink Control's Visibility

问题描述

<!-- Home -->
      <li class="current"><a href="Home.aspx">Home</a>
      
      
        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="userwelcome.aspx">My Page</asp:HyperLink></li>
      </li>  

我想在session ["username"] == null时隐藏此超链接，
而且我的想法很好，但是当session为null时就会出现问题，因为它与

i want to hide this hyperlink when the session["username"]==null,
and my this idea working fine but there is a problem when session is null then because it is with in

<li>hyperlink</li>

因此它在超链接"中隐藏了我的页面"文本，但显示了空白方形"框.(因为当可见性为false时，超链接的文本不存在)

我想隐藏这个空白的方形框.
有任何想法吗?

so it hides the My Page text from the Hyperlink but showing Blank Square box.(because hyperlink''s text is not there when visibility is false)

i want to hide this blank Square box.
Any Idea?

推荐答案

我不确定我是否很好地解决了您的问题...
要隐藏超链接，您只需键入:

I am not sure I get your problem well...
To hide the hyperlink you can just type:

HyperLink1.Visible = !(session["username"]==null);

如果出现渲染问题，则可能是probalby，因为您只有2个闭合"li"用于一个开口.

If you have rendering issue it is probalby because you have 2 closing "li" for only one opening.

您好
您可以在li内使用runat ="server"属性，并在隐藏链接按钮时也将其隐藏.希望对您有所帮助.

Hi
You can use a runat="server" attribute inside li and hide that also when you hide the link button. Hope that helps you.

<ul  runat="server" id="hide">
         <li> <asp:hyperlink id="HyperLink1" runat="server" navigateurl="userwelcome.aspx" xmlns:asp="#unknown">My Page</asp:hyperlink></li></ul>

然后在代码后面我写了

and in codebehind i wrote

if (Session["email"] == null)
        {

           HyperLink1.Visible = false;
            hide.Visible = false;
            

        }
        else if (Session["email"] != null)
        {

           
            HyperLink1.Visible = true;
            hide.Visible = true;


        }

我添加了

I Added

Runat="Server"

和

id="hide"

到

<ul>

标签，然后在会话为null时将可见性设置为false，否则设置为true:)

tag then set the visibility false when session is null else true :)
