1、上图看效果
今天要做的一个案例是这样的效果,它能实时监测车间设备有关数据,并以表格和图形显示在界面上,这个比上个案例要复杂些,颜值也高些,通过这个来巩固wpf的技能,用到了命令绑定,样式资源,表格数据,图形控件livechart。将前面25的内容熟悉起来,就可以自己动手做这个案例了。
2、创建wpf项目
3、 UI布局分析
整个界面是一个表格,表格分二行,第一行是标题栏,第二行是数据栏,
第二行分2列,第1列放表格控件,第2列放图形控件
第一行分7列,放7个控件
1、 第一行
2、第二行
WPF中的布局是表格布局风格,通过一个个的细化组合形成UI,完整代码如下,大家可以仔细看看,注释都有,仔细体会下,不算难:

</Window>
3、样式资源
样式文件就是WEB中的css属性设置,需要精细的考虑,软件的界面就是一个人的颜值,可以看看,用的时候改改。

4、视图模型
视图模型的意思是指UI界面与后台的哪个模型类绑定起来,业务逻辑由视图模型来决定,前台的UI界面只负责数据的渲染,这里都是命令绑定和属性绑定。
1、命令绑定
2、属性绑定
这里是图形的参数绑定后台属性,意思是一样的。注意什么时候用双向,单向。当后台逻辑数据发生更改时,需要更新UI控件就使用双向绑定。

5、运行起来
这里面用到异步task,而不是winform中的定时器。
