到官网得到消息自13.2版本后的Dev Grid中均内置了CheckBox列多选功能。在寻找答案的过程的成果进行记录。

一、13.2版本以后用法

1. 启用多选列
   对Gird中的View进行以下属性设置：
   

    gridView1.OptionsSelection.MultiSelect = true; gridView1.OptionsSelection.MultiSelectMode = GridMultiSelectMode.CheckBoxRowSelect;

2. 清除当前选择
   在选中列时后，可配置在选中列以外的地方点击时候会清除当前的选择。14以后才有此功能
   gridView1.OptionsSelection.ResetSelectionClickOutsideCheckboxSelector = true;
3. 获取选中的行

二、早起版本实现

   GridCheckMarksSelection类

    

2. 使用方法
   

   1 public Form1()2  {3       InitializeComponent();4       new GridCheckMarksSelection(gridView1);5   }

    

DevExpress Grid使用checkBox选中的方法
