安装完DevExpress后，实现一个可以选择多个条件的搜索功能，效果如下

## 实现 ##

新建一个窗体，拖拽checkEdit控件和textEdit控件，使页面布局如下

怎样判断选项被选中

if (ceTaskFile.Checked)

其中ceTaskFile就是checkEdit控件的Name属性。

怎样获取输入框的名字

this.txtTaskFile.Text

其中txtTaskFile就是输入框对应的Name属性

怎样实现并列多选的效果

将要筛选的结果存放在list中，然后依次判断每个选择框是否被勾选，如果被勾选，则将结果按照勾选条件进行筛选。

在下面点击查询的按钮的点击事件中

List<DataTreeNode> data = new List<DataTreeNode>(); //存储要筛选的结果
    data = DataTreeListHelper.ParseDir(Common.Global.AppConfig.TestDataDir, data); //获取要查询筛选的结果
    if (ceTaskFile.Checked)
                {
                  
                    if (String.IsNullOrEmpty(this.txtTaskFile.Text))
                    {
                        string msg = "请输入任务文件名!";
                        DevExpress.XtraEditors.XtraMessageBox.Show(msg, "标题", MessageBoxButtons.OK, MessageBoxIcon.Information);
                        return;
                    }
                    else
                    {
                        data = data .Where(p => p.NodeText.ToLower().Contains(this.txtKeyWork.Text.ToLower()));
                    }
    
                }
    if (ceKeyWord.Checked)
                {
                    if (String.IsNullOrEmpty(this.txtKeyWork.Text))
                    {
                        string msg = "请输入关键字!";
                        DevExpress.XtraEditors.XtraMessageBox.Show(msg, "标题", MessageBoxButtons.OK, MessageBoxIcon.Information);
                        return;
                    }
                    else
                    {
                        data = data .Where(p => p.NodeText.ToLower().Contains(this.txtKeyWork.Text.ToLower()));
                    }
                }
