creating a dynamic valuehelp in webdynpro abap

Hello,

I am doing some development in Webdynpro Abap.

At this point I am unable to use the standard valuehelp provided in the system for selecting some values in an SAP HR system. Would there be any code samples for coding a custom value help in Webdynpro for ABAP. One of the things I have to be able to do is to dynamically generate the values of the valuehelp based on the value of some other fields on the screen that I am coding.

Any code samples or links will be appreciated.

Thanks for your help.

Best Regards

Sumit Agarwal.
