I am working on this form where it has drop down and text box. When value selected in one drop-down should change value in text-box dynamically.
for eg if I select a value "3" in select box then
select ename from emp where eid ='3';
and result should be in text box
Similarly form has multiple drop-down list with respective text-box.
Please suggest. Thanks in advance.
