setSelectedIndex

public void setSelectedIndex(int selectedIndex)
The ordinal index of the selected option, starting from 0. The value -1 is returned if no element is selected. If multiple options are selected, the index of the first selected option is returned.


getValue

public String getValue()
The current form control value (i.e. the value of the currently selected option), if multiple options are selected this is the value of the first selected option.

public void setValue(String value)
The current form control value (i.e. the value of the currently selected option), if multiple options are selected this is the value of the first selected option.


getLength
