Using dropdown and listboxes to enable user selection

Please see the attached file.
The program should allow users to select one or more options from the dropdown boxes.  The selected option gets put into the listbox.  When the user presses apply filter the items in the list box get sent to the stored procedure.
To make it work I use textboxes and hidden fields with javascript.
I want to make the textboxes eg txtfilenamecode invisible or at least disabled.  However this causes the program to fail.  
Any suggestions?

What you are describing fits more inline when using the CheckboxList control. Is there a design reason that you are using drop-down controls and list boxes to allow for multiple selections?

You can make textboxes invisible the using CSS which will not affect postback that you comment about in the attachment. To do this, add either a CssClass with a "display: none;" or add directly to your control a style property.

How would you use a checkboxlist if a dropdownbox could have hundreds of items?  I found it clogged up the web page, so was seeking an alternative.

You can enclose your checkboxlist control in a DIV and apply CSS to the DIV to limit its size. The CSS looks something like this:
.checkBoxList {
  max-height:100px;
  height:auto !important;
  height:100px;
}
