Asp.net 在aspx.page中设置ascx的可见性

asp.net vb.net

Asp.net 在aspx.page中设置ascx的可见性,asp.net,vb.net,Asp.net,Vb.net,在我的母版页中，左侧内容有ContentPlaceHolder，右侧内容见下文： <body class="software"> <form id="form1" name="MyFrom" runat="server"> <telerik:RadScriptManager runat="server" ID="RadScriptManager1" ></telerik:RadScriptManager>

在我的母版页中，左侧内容有ContentPlaceHolder，右侧内容见下文：

<body class="software">
    <form id="form1" name="MyFrom" runat="server"> 
    <telerik:RadScriptManager runat="server" ID="RadScriptManager1" ></telerik:RadScriptManager>    
        <div>
            <div id="wrapper">
                <menu:main id="mainMenu" runat="server"/>
                <div id="leftCol">
                    <asp:ContentPlaceHolder ID="LeftContent" runat="server">
                    </asp:ContentPlaceHolder>
                </div>                               
                <div id="rightCol">                                                 
                    <asp:ContentPlaceHolder ID="RightContent" runat="server">
                    </asp:ContentPlaceHolder>
                </div>      
            </div>
        </div>        
    </form>
</body>

这就是我在rptReport.ascx上看到的内容：

<%--Right Side--%>
<div id="rightCol" >
    <div class="elementHeader" id="elementHeader">
        <span class="text"><asp:Label ID="lblReports" runat="server" Text="Reports"></asp:Label></span>
    </div>   
    <div id="divRightWrapper" class="rightWrapperDiv" runat="server">
    <div>
        <img id="imgCaseGlobalReports" runat="server" alt="" src="~/Images/Replacements/IncidentReports.png"/>
    </div>

    </div>
 </div>

FindControl的工作方式是匹配

名称

属性，而不是匹配源文件的相对路径。在第一次调用FindControl时它是正确的，但是第二次调用是不正确的。实际上，它与

id

属性值匹配，而不是

Name

.Me.Master.FindControl（“RightContent”），直到这里工作正常，但是如何将ascx设置为false可见

rptReport

控件在代码中的位置？你能给我看看吗？我修改了我的问题。。。我的rptReport是位于以下路径中的ascx:“/Controls/Reports/rptReport.ascx”

<%--Right Side--%>
<div id="rightCol" >
    <div class="elementHeader" id="elementHeader">
        <span class="text"><asp:Label ID="lblReports" runat="server" Text="Reports"></asp:Label></span>
    </div>   
    <div id="divRightWrapper" class="rightWrapperDiv" runat="server">
    <div>
        <img id="imgCaseGlobalReports" runat="server" alt="" src="~/Images/Replacements/IncidentReports.png"/>
    </div>

    </div>
 </div>
