C_ 中通用winform组件的数据绑定（国外英文资料） Data binding for general winform components in c # We know that in the Visual c # no class library itself, and other. Net development language, the class library is called Visual c #. Net FrameWork of a Shared library -. T FrameWork SDK. ADO.NET is a collection of a library of libraries developed by FrameWork SDK for development language. In ADO.NET, there is a large number of libraries for database connection and data processing, but there is no such thing as DbText components, DbList components, DbLable components, and DbCombox components.

This allows the programmer to customize the data display methods and content to prepare for future data processing. So the data binding is the foundation and the most important first step in Visual c # for database programming. Only to grasp the method of the data binding, can be very convenient to open the record of data set to browse, delete, insert specific operations, data processing, etc. Data binding can be divided into two types based on different components, one for simple data binding and one for complex data binding. A simple model of data binding is binding component display field after just a single record, this binding on the use of a single value is displayed in the general components, such as: TextBox components and Label. And complexity of data binding is displayed after binding component field is more records, this binding generally use o
