What is initial value of an empty drop-down?

-

i have written script populate items in drop-down list if there no entry existing.

the problem have recognizing list empty. have tried test null (if dropdown.isnull = true) , testing the

rawvalue = "" , bunch of other things no result.

i'm sure easy apparently not me.

thanks help!

those commands testing value selected user. have not selected yet not have value.

 

the command:

 

dropdownlist1.items.nodes.length

 

 

will give number of items in ddlist. 1 based. note not count items added dropdown user.
