@hdjdchen
你好，我出现了跟你上面提到的一样的问题，会送以后就Enabled还是初始绑定的那样变不了，另外我没有用模板页，请问你是怎么解决的呀？？[code=csharp]
[ExpressionEditor(typeof(PermissionExpressionBuilderEditor))]
[ExpressionPrefix("Permission")]
public class PermissionExpressionBuilder:ExpressionBuilder
{
public override CodeExpression GetCodeExpression(BoundPropertyEntry entry, object parsedData, ExpressionBuilderContext context)
{
string operationName = entry.Expression;
return new CodePrimitiveExpression(PermissionManager.CheckPermission(operationName));
}
public override bool SupportsEvaluate { get { return true; } }
public override object EvaluateExpression(object target, BoundPropertyEntry entry, object parsedData, ExpressionBuilderContext context)
{
string operationName = entry.Expression;
return PermissionManager.CheckPermission(operationName);
}
}
public class PermissionExpressionBuilderEditor : ExpressionEditor
{
public override object EvaluateExpression(string expression, object parseTimeData, Type propertyType, IServiceProvider serviceProvider)
{
//return expression + ":" + parseTimeData + ":" + propertyType + ":" + serviceProvider;
string operationName = expression;
return PermissionManager.CheckPermission(operationName);
}
}

re: Clustered Index & Non Clustered Index(原创) Justin 2008-09-10 22:08
写的很好，学习！
re: Clustered Index & Non Clustered Index(原创) Matt Yeung 2008-06-18 09:35
每个表其实都应该尽量设置clustered，
可选择性的设置nonclustered字段-- 如果除了clustered字段外还有其他需要频繁查询的字段. 需要记住的是nonclustered 比clustered占用多一倍的空间 re: Clustered Index & Non Clustered Index(原创) 区别 2008-06-16 21:53
两个有什么区别呢？是不是都要创建Clustered

非常感谢..已经解决了.

你需要把<%@ Master Language="C#" CompilationMode="Never" %> 写在master page 中强迫asp.net不把该叶面编译成实例，这样做牺牲性能，但能够实现这种小粒度权限验证
re: 介绍ASP.NET 2.0 新特性(expressionBuilder)对用户界面小粒度权限验证的支持 hdjdchen 2007-08-16 21:25
你好, 我也根据你的设计写了类似的继承expression builder的自定义类型,但我发现在编译后代码第一次运行的时候(还没有进入登陆界面接收到用户登陆ID信息), CLR就已经开始加载自定义的expression builder来解释含有<%# %>的页面, 以后就不再解释该页面了,这样的话我的权限验证只能拿到TASK的信息而拿不到USER的信息,不能进行验证.请问这是什么原因?
?? 相关ASPX设为非编辑页面就行了?? 在那里设置??请指教.. re: 介绍ASP.NET 2.0 新特性(expressionBuilder)对用户界面小粒度权限验证的支持 Matt Yeung 2007-05-30 18:29
调用的叶面需要定义
<%@ Master Language="C#" CompilationMode="Never" %> 来防止IL编译器编译该页面。 re: 介绍ASP.NET 2.0 新特性(expressionBuilder)对用户界面小粒度权限验证的支持 Matt Yeung 2007-05-30 18:24

你好能不能发个完整的DEMO给我啊？
谢谢你啊 xtb_sp@163.com re: 介绍自定义安全管理框架的数据结构 mextb1860 2007-05-15 12:22

我实现了一个组合模式，但是不知道如何迭代组合里的每一个叶子结点
