【IT168 技术文档】一个不错的DataGridView数据窗口控件《DataGridView数据窗口控件开发方法及其源码提供下载》，这种控件在有些场合下，还是非常直观的。因为，在一般要求客户录入数据的地方，一般有两种途径，其一是通过弹出一个新的窗口，在里面列出各种需要输入的要素，然后保存的，如下图所示;
其二就是直接在DataGridView中直接输入。这两种方式各有优劣，本文介绍采用该控件实现第二种模式的数据数据。如下图所示
这种方式，直接通过在DataGridView中下拉列表或者文本框中输入内容，每列的数据可以联动或者做限制，实现用户数据的约束及规范化。
控件只要接受了DataTable的DataSource之后，会根据列的HeadText内容，显示表格的标题及内容，应用还是比较直观方便的。
