Server-side Events

Event log

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

  • OnCheckedChanged—raised when the checked state of RadCheckBox changes and AutoPostBack is set to true.
  • OnClick—raised when the RadCheckBox is clicked and AutoPostBack is set to true.
  • OnCommand—raised when the RadCheckBox is clicked and AutoPostBack is set to true. It is useful for handling commands (using the CommandName and CommandArgument properties).
  • DefaultVB.aspx
  • DefaultVB.aspx.vb
