  • string $value: the URL to navigate to when a HotSpot object is clicked.
setPostBackValue (line 411)
  • access: public
void setPostBackValue (string $value)
  • string $value: a value that is post back when the HotSpot is clicked.
setTabIndex (line 427)
  • access: public
void setTabIndex (integer $value)
  • integer $value: the tab index of the HotSpot region.
setTarget (line 477)
  • access: public
void setTarget (string $value)

setValidationGroup (line 459)
  • access: public
void setValidationGroup (string $value)
  • string $value: the group of validators which the hotspot causes validation upon postback
setViewState (line 318)

Sets a viewstate value.

This function is very useful in defining setter functions for control properties that must be kept in viewstate. Make sure that the viewstate value must be serializable and unserializable.
