需要做一个控件实现数据对输入功能,用Dictionary来存数据,Key取自数据库,Value为输入值,请指教!
一个录入界面,用控件来实现.使用Dictionary<string, string> _values = new Dictionary<string, string>()来存数据,界面如下:移交部门 Value 数量 Value
单位名称 Value 价值 Value
格式为一个表格形式,Key的值取自数据库,Value为一个文本框需要输入数据,控件能把一对对的Key和value值存到_values 里,然后写入数据库.该怎么实现请指教.谢谢!

补充：.NET技术 , 组件/控件开发
