DevExpress gridcontrol添加了复选框删除选中的多行/批量删除的方法

思路：遍历gridView1的每一行，该行中checkbox列被勾选则设置该行为选中状态，执行gridView1提供的DeleteSelectedRows方法则可

public void DoDelete()
        {
           
            for (int i = 0; i < gridView1.DataRowCount; i++)
            {
               if (gridView1.GetDataRow(i)["checked"].ToString().Trim().ToLower() == "true")
                {
                    gridView1.SelectRow(i);
                }
                else 
                {
                    gridView1.UnselectRow(i);
                    continue; 
                }
                               
            }

            this.gridView1.DeleteSelectedRows(); 

            gridView1.RefreshData();
        }
