Question

目前，我的代码隐藏了Panel ItemTemplate中包含的某些FormView，这些((Panel)FormView1.FindControl("pnlIsAdmin")).Visible = IsAdmin;依赖于用户角色。

目前的解决方案：.Databind();

问题是，在Formview完成之前，此代码无法运行.Databind();

现在我对FormViews了解不多，但我确实有一种方法可以将控件（例如上面的面板）隐藏在更好的位置，而不依赖于SEVERE: End event threw exception java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.tomcat.util.IntrospectionUtils.callMethodN(IntrospectionUtils.java:379) at org.apache.tomcat.util.descriptor.web.CallMethodMultiRule.end(WebRuleSet.java:1034) **Caused by: java.lang.IllegalArgumentException: The servlets named [AxisServlet] and [cxf] are both mapped to the url-pattern [/services/*] which is not permitted at org.apache.tomcat.util.descriptor.web.WebXml.addServletMapping(WebXml.java:308)** ... 32 more Aug 19, 2015 5:42:23 PM org.apache.tomcat.util.descriptor.web.WebXmlParser parseWebXml SEVERE: Parse error in application web.xml file at file:/D:/APP_NAME/eclipse/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/beA_WS/WEB-INF/web.xml org.xml.sax.SAXParseException; systemId: file:/D:/APP_NAME/eclipse/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/beA_WS/WEB-INF/web.xml; lineNumber: 49; columnNumber: 21; Error at (49, 21) : The servlets named [AxisServlet] and [cxf] are both mapped to the url-pattern [/services/*] which is not permitted Caused by: java.lang.IllegalArgumentException: The servlets named [AxisServlet] and [cxf] are both mapped to the url-pattern [/services/*] which is not permitted at org.apache.tomcat.util.descriptor.web.WebXml.addServletMapping(WebXml.java:308) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.tomcat.util.IntrospectionUtils.callMethodN(IntrospectionUtils.java:379) at org.apache.tomcat.util.descriptor.web.CallMethodMultiRule.end(WebRuleSet.java:1034) at org.apache.tomcat.util.digester.Digester.endElement(Digester.java:956) ... 25 more SEVERE: Marking this application unavailable due to previous error(s) -->（比如on页面加载）??

感谢您提供任何信息。

我通常不喜欢混合我的代码隐藏＆amp;显示页面，但您可以将控件包装在某些服务器标签中：

<% if(isAdmin){ %> <asp:Panel ID="pnlIsAdmin" runat="server"></asp:Panel> <% } %>
