In a multi select box , unless user select option(s) , will it not be possible to send the values back to the server ,in the form of request parameter
For example i have dual multi select box where user can add his selection from one list box to the one on right by clicking on a button or remove [it re-populates the one on left ]
in this scenerio when i access the value of the select box , i dont get any values there unless if its selected
Another way, is to create a hidden field, and again, just before submitting the form, iterate through your second multiselect box, and add the option values to this hidden field [comma separated or something like that], without actually selecting any of the options - and then submit the form. In server side, you can get the value of the hidden field, and hence know what are the options in that second box.
By the way, just curious, what is stopping you from using the first solution?
