GridPattern
支持GridPattern的最常见的控件为GridView， 在WPF中使用ListView和GridView组合即可得到相应的GridView。
GridPattern的方法GetItem：此方法有两个参数，即DataGrid的Row和Column。
通过GridPattern的GetItem方法可以获取DataGrid中的某个确定的单元格，进而对单元进行操作。
对单元格的操作主要有以下几个方面：
1.编辑单元个中的数据。
2.获取单元格中的数据。
3.获取单元格中嵌套的AutomationElement（一般使用与自定义控件中）。
GridPattern的属性GridPattern的Current属性中有如下两个属性：
1.RowCount属性：GridPattern二维表格的行数。
2.ColumnCount属性：GridPattern二维表格列数。
下面我们通过一个实例来演示自动化测试中如何使用GridPattern来测试GridView的方法：
