Usage of DWZ in APS. NET WebForm (1), dwzwebform1. Preface In recent project development, the front-end framework DWZ was used. DWZ is a relatively good background management interface framework, but the officially published documents are really shameful, simple pages, a little irresponsible for their own products. At the same time, I would like to thank the netizen Shi for his enthusiastic help and help me a lot when I am a cainiao.2. Introduction Of

Client Server interaction through webform Because HTTP connections are stateless, the page status cannot be saved through connections. Asp.net proposes a solution to save the current status of the page, the page with viewstate is used to store the final values of all page elements in the hidden 64-bit encoded string _ viewstate.
