Explain the components of web form in ASP.NET?

Server controls - The server controls are Hypertext Markup Language (HTML) elements that include a runat=server attribute. These controls provide automatic state management and server-side events and respond to the user events by executing event handler on the server. HTML controls - These controls also respond to the user events but the events processing happen on the client machine. Data controls - Data controls allows us to connect to the database, execute command and retrieve data from database.
