Controlling drop down lists in Windows SharePoint Services 3.0 Form

Question

I have created a form in a WSS 3.0 site. There are a number of drop-down lists on the form. Is there a way to control the values in one drop-down based on a selected value in a previous drop down?

Answer 1

On post-back you should be able to access the previously selected controls value.

If not, then you might want to try the Control.FindControl method.

Answer 2

The cascading dropdowns issue is a big one. There are some solutions that people have built with custom field controls and/or site columsn. Here's a link to a solution that will let you set up multiple levels of parent-child relationships.

Answer 3

It seems this sort of cascaded lookup is big issue indeed. This thread digs this issue little bit dipper:
