Drop-down menu: lock after choice is made?

[Former Community Member]

Is it possible to lock the choice in a drop-down menu after it is made, so when the document is saved and then opened again, the choice cannot be changed?

Sure ...just lock the field on exit.

You could put something like the following on the initialize event of the field - the field will remain open until the file is saved with a value in the field, if there is no value the field will remain open when the file is saved and opened.

//form1.subMain.DropDownList1::initialize - (JavaScript, client)

if (!this.isNull){

this.access = "readOnly";

}
