Answer 1

div 在repeater里面  后台控制不了它

Answer 2

<div id="admins" style=<%# Eval(getPower()) == "1" ?显示样式：隐藏 %>>

Answer 3

<asp:Repeater ID="rptBlog" runat="server" DataSourceID="objBlog" OnItemDataBound="rptBlog_ItemDataBind">
    <ItemTemplate>
        <div id="rptBlogTitle">
            <h3>
                <a>
                    <%#eval_r( "blogTitle") %>
                </a>
            </h3>
            (
            <%#eval_r( "blogDate") %>
                )
        </div>
        <div id="divBlogEditDel" runat="server" visible="false">
            <a href="EditBlog.aspx">

            <a href="blogContent.aspx">
                查看全文
            </a>
        </div>
    </ItemTemplate>
</asp:Repeater>
后台代码：?
protected void rptBlog_ItemDataBind(object sender, RepeaterItemEventArgs e)
        {
            if (Session["UserName"] != null)
            {
 
                if (Session["UserName"].ToString() == this.bc_UserName.GetBlog_UserName())
                {
                    e.Item.FindControl("divBlogEditDel").Visible = true;
                }
            }
        }

Answer 4

 private void getPower()
        {            string name = Session["username"].ToString();
            string signer = new UserManager().getUserByName(name).U_signer;
            if (signer == "1")
            {
                FindControl("admins").Visible = true;
            }        }
我这样有错啊  求大神

Answer 5

注意，是放在Repeater控件行数据绑定事件里
protected void rptBlog_ItemDataBind(object sender, RepeaterItemEventArgs e)
        {
           string sign=getPower();
           if(sign=="1")
           {
             e.Item.FindControl("LinkBtn_delete").Visible = true;
             e.Item.FindControl("LinkBtn_delete").Visible = true;
             e.Item.FindControl("LinkBtn_delete").Visible = true;
           }
           else
           {
             e.Item.FindControl("LinkBtn_delete").Visible = false;
             e.Item.FindControl("LinkBtn_delete").Visible = false;
             e.Item.FindControl("LinkBtn_delete").Visible = false;
            }
        }

Answer 6

<%# Eval(getPower()) == "1" ? "class=' 显示div样式'": "class=‘隐藏div样式’"%>

Answer 7

前台
<%# getPower()== "1" ? "显示div'admins'": "隐藏div"%> 
后台
 public string getPower()         {               string name = Session["username"].ToString();             string signer = new UserManager().getUserByName(name).U_signer;             if (signer == "1")             {                 return "1";             }  else{turn "0";}         } 

Answer 8

就是不知道 显示div'admins' 怎么写  "隐藏div"怎么写

Answer 9

直接在前台写的话就
<%if (Eval(getPower()) == "1")
{%>
<div id="admins" style="display:block">
<asp:LinkButton ID="LinkBtn_delete" CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="1">删除</asp:LinkButton>
</div>
<%}
else
{%>
<div id="admins" style="display:none">
<asp:LinkButton ID="LinkBtn_delete" CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="1">删除</asp:LinkButton>
</div>
<%}
%> 

Answer 10

给div 加个runat="server" 和id 后台就可以获取到visible值 没有测试 只是给个思路

Answer 11

 <div style="width: 80px; display: <%#(Eval("Guid") is DBNull) ||(Eval("Guid")== null) ? "none" : "block" %>">

Answer 12

大体思路这样
<asp:panel  id="admins" runat="server">
    <asp:LinkButton ID="LinkBtn_delete" CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="1">删除</asp:LinkButton><br />
</asp:panel>
protected void rptBlog_ItemDataBind(object sender, RepeaterItemEventArgs e)
        {
//这里需要判断是否ITEM
            string signer = new UserManager().getUserByName(Session["username"].ToString()).U_signer;
            if (signer == "1")
            {
                (Panel)e.Item.FindControl("admins").Visible = true;
            }
   else{}
        }

Answer 13

<%if (Eval(getPower()) == "1")
{%>
  <div id="admins">
                            <asp:LinkButton ID="LinkBtn_delete" CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="1">删除</asp:LinkButton><br />
                            <asp:LinkButton ID="LinkBtn_top"    CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="2">置顶</asp:LinkButton><br />
                            <asp:LinkButton ID="LinkBtn_un_top"    CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="3">取消置顶</asp:LinkButton>
                        </div>
<% } %>

Answer 14

<div id="admins" style="display:<%# Eval(getPower()) == "1" ? "block": "none"%> ">                             <asp:LinkButton ID="LinkBtn_delete" CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="1">删除</asp:LinkButton><br />                             <asp:LinkButton ID="LinkBtn_top"    CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="2">置顶</asp:LinkButton><br />                             <asp:LinkButton ID="LinkBtn_un_top"    CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="3">取消置顶</asp:LinkButton>                         </div>

前台：
<td>
                       <div id="admin"  <%# getPower()== "1" ? "style='display:block'": "style='display:none'"%>  >管理
                        <div id="admins"  >
                            <asp:LinkButton ID="LinkBtn_delete" CommandArgument='<%#Eval("T_id") %>'  runat="server"  CommandName="1">删除</asp:LinkButton><br />
                            <asp:LinkButton ID="LinkBtn_top"    CommandArgument='<%#Eval("T_id") %>'  runat="server" CommandName="2">置顶</asp:LinkButton><br />
                            <asp:LinkButton ID="LinkBtn_un_top"    CommandArgument='<%#Eval("T_id") %>'  runat="server"  CommandName="3">取消置顶</asp:LinkButton>
                        </div>
                       </div>
                       </td>
后台：public string getPower()
        {
            
              string name = Session["username"].ToString();
            
              string signer= new UserManager().getUserByName(name).U_signer;
              if (signer == "1"&&name!="")   
              {                
                  return "1";             
              }  
              else{return "0";}   
          
        }
