I have a requirement to create a form that will allow user to select through list of values in three dropdown list box which will change based on the previous selection. The final list box will have values based on the previous selection and should allow user to select multiple values and store all these selected values and repeat this whole process with in same form until user close the form.
I have created two cascading dropdown list box and a listbox to display multiple values. But I don't know how to allow user to make multiple selection. I am not able to use Multiple Selection List Box. So I tried to copy the selection values from listbox to text vox. But I don't know how to copy multiple values from listbox to text box.
