Server-side Events

Event log

RadImageButton exposes several server-side events that allow easy and flexible use in a wide range of application scenarios:

  • OnClick—raised when the RadImageButton is clicked and AutoPostBack is set to true.
  • OnCommand—raised when the RadImageButton is clicked and AutoPostBack is set to true. It is useful for handling commands (using the CommandName and CommandArgument properties).
  • DefaultCS.aspx
  • DefaultCS.aspx.cs
  • styles.css
