Interface development requires a certain amount of time for both Web development and Winform development, especially for interfaces with a large number of database fields, generally, more controls need to be placed on the editing interface for data display. Every time this happens, it is a headache. Repeated mechanical operations make people very tired and annoying, however, this is required.
Because database fields are related to the page layout, you can use the database metadata of the
