I want to populate the values in the listbox based on the value entered in other field. How to achieve this in Webdynpro. Though if I am attaching an event it is not getting triggered.
I have created a listbox element for the field Payment terms. If i am entering a vendor the possible payment terms needs to be populated in the list box.
You have to write the code to populate the list box values on the on enter event or on select event of Your Vendoe field.. so that each time you change the vendor that method to populate the list box is called.
Primarly when the view is displaying for the first time is it displaying some thing on the listbox?
Try writting the code the modify view based on some conditions. Try checking the context values at run time after the event happening on vendor field. If the Context is having changed values after the event from vendor field, avoid context mapping and try filling the list box using the method of if_wd_listbox.
