how to prevent empty selection in dropdown listbox

Former Member

Is it possible to disable the possibility of selecting no value in the dropdown listbox, so that it is not possible for the user to select the empty line which always gets added to the list of choices? Ideally, this empty line would not be shown at all...

thanks,

chris

Hi Christoph,

the selection behaviour is defined by the selection cardinality of the context node where the drop-down list gets its data (when using *ByIndex data binding).

Use selection cardinality 1:1 instead of 0:1.

Note: setting the "state" property to "required" does not help, as one would possibly expect...
