Common properties for all Server Controls

Common properties for all Server Controls

Most of the server controls share some common behavior.

Part of this behavior includes the so-called properties that define the data a control can contain and expose.

ID-> uniquely identify it in the page

 Runat-> attribute that set to Server to indicate the control should be processed on the server

 ClientID-> contains the client-side ID attribute that will be assigned to the element in the final HTML.

Note:

 In versions of ASP.NET up to 3.5 this ClientID was always generated for you automatically. However, in ASP.NET 4 a new ClientIDMode property has been introduced that gives you more control over the ID of an element at the client.
