原标题:How to make an ObjectResult filterable

这似乎很简单,但我似乎过于密集,无法说明。 I m 采用简单的<代码>获得反对 标书;在数据表中仅记录几个。 我将这个词命名为<代码>。 资料来源:财产。 然后,我看看<密码>的角度看待财产,见<编码>CanFilter和CanSor。 当我收到《DefaultView》时,它表明,是假的。 由于这些只是读写的,我不能改变价值。 现在,我想在检索的数据上安装一个过滤器(或分类),而不必再回服务器KQ,但对于我来说,我找不到一种方法,使这些数据与这些特性相符。

我尝试使用<代码>ObjectResult.As Queryable<T>和CanFilter ,但意见类型从System.Windows.Data.BledListCollection改为,我无法找到一种方式将这种观点插入。 记名 意见重新编号为<条码>。

任何要点都将受到高度赞赏。

问题回答
