Performance issue with Forms Services & Drop down lists

A little post about performance issue with Forms Services & Drop down lists

Avoid many dropdown List

There is a performance
issue with Internet Explorer version 6 if the form contains a lot of “drop down
list” controls. Internet Explorer version 7 do not have this issue due to its
JavaScript engine improvement.

This issue happen when
there are more than 5 Dropdown lists on a form with hundred of values.

Workaround: Create multiples views
in order to limit the number of control displayed on the page.

Remark: Dynamic retrieve values for each dropdown list on an action is not a
solution except if once you use it, you remove it from the form. Otherwise, at
your last dropdown list, you will have all the dropdown lists present in the
form and you will meet the performance issue.
