Lookupedit使用求助，跪求帮助
lookupEdit，绑定数据源后，无论选择哪一行数据，鼠标单击完之后，都是显示第一行数据，怎么都调整不好绑定数据源代码
#region//添加lookup数据源
Public_class.LookUpEdit_Tools.InitLookUpEdit(lookUpEdit_distributor,
new string[] { "en_name", "distributor" },
new string[] { "客户名称", "分销商" },
new int[] { 50, 80 },
dictionart_fxs, "en_name", "distributor", 5);

使用的方法：
#region//初始化LookUpEdit控件 (加载数据表中的一列或多列，且显示下拉列标题，可以设置下拉列的宽度)
/// <summary>
/// 初始化LookUpEdit控件 (加载数据表中的一列或多列，且显示下拉列标题，可以设置下拉列的宽度)
