高级查询，自定义查询条件，自定义要显示的查询结果。
效果展示：
1.“查询模块“、”条件“的数据绑定。
在界面拖一个GridControl，ColumnEdit选择repositoryItemComboBox，FieldName设置ITEM_CLASS_CODE。
查询模块和条件的值存入XML文件。

foreach (DataRow row in _configInfo.Rows)

4.显示设置
思路： 点击显示设置时，判断字段CANSHOW的值，来确定勾选CheckedListBox的哪些项。
获取选中的项
设置时，每个CheckedListBox项循环判断是否选中，选中则设置XML中的CANSHOW为1，否则为0

/// 绑定ListBox项以及勾选内容
///
///
///
private void LoadCheckList(CheckedListBoxControl chkLis, string itemClassCode)

chkLis.DisplayMember = "ITEM_NAME";
chkLis.ValueMember = "ITEM_CODE";

{
if (chkInfo.Rows[itemIndex]["CANSHOW"].ToString() == "1")
