Client-side API

  • Demo Configurator
Client-Side API Commands
  • Enter a URL, e.g., https://www.wikipedia.org/
  • AutoPostBack

RadButton provides flexible and rich client-side API. Here are some of the key client-side functions:

  • get_text()—returns the text displayed in the RadButton control
  • set_text(text)—sets a text to be displayed in the RadButton control
  • get_autoPostBack() —returns a bool value indicating whether the control will automatically postback to the server
  • set_autoPostBack(true/false)—disables or enables the AutoPostBack behavior of the RadButton control.
  • DefaultVB.aspx
  • scripts.js
