C#WPF实战出真汁13--【营业查询】

1、营业查询介绍

本模块是最后一个模块，该板块需要的功能有：营业数据列表，查询数据，导出数据，数据统计。

2、UI设计布局

TabControl 是 WPF 中用于创建多页标签式界面的控件，常用于组织多个子内容区域。每个子内容通过 TabItem 定义，用户可以通过点击标签头切换内容，通过修改样式和模板，可以完全自定义 TabControl 的外观。可以通过代码动态管理 TabControl 中的 TabItem，TabControl 支持数据绑定，可以通过 ItemsSource 属性绑定到一个集合，并使用 ItemTemplate 定义标签头的显示方式，TabControl 提供了多个有用的事件，例如 SelectionChanged，可以在用户切换标签页时执行自定义逻辑：通过设置 TabStripPlacement 属性，可以改变标签头的位置，使其显示在左侧、右侧或底部。

3、viewmodel模型

ViewModel 的主要职责是封装业务逻辑和状态，为视图提供数据绑定和命令绑定的接口。通过数据绑定，ViewModel 能够将数据从 Model 传递到 View，同时处理用户输入和界面逻辑，而无需直接操作 UI 元素，viewmodel就是一个类，这个类中包括了变量，属性，命令，其中属性和命令是最重要的，属性是动态通知属性，当属性的值发生更改时，自动更新界面元素标签，反过来也是这样的，命令来说就是响应事件，如单击，双击，右键等。
