I have editable listview. I have drop-down list control and text box. The drop-down list control is pulling in the values from a seperate list. I would like to populate the text box control with the values from this same list based upon drop-down list selection.

If I use drop-downlist instead of the text box, it works but I was hoping to have a read-only text box so it displays the value based upon the drop-down list selection

Any hint?
