Dropdown List box constrained/Filtered by another Dropdown List Box

Posted on by Siopold 32

Hi,

I have a form that has a number of dropdown lists. Some of these dopdown lists contain a LOT of records.

I want to be able to filter  Dropdown2 depending upon what has been chosen in Dropdown1.

Example

I choose  'Project003'   from Dropdown1

I  only see two options available in Dropdown2 (not the full 20 or whatever) obviously there would have to be be some kind of relationship table where I can filter this

I am not an X++ developer but have done something like this in the past, different language, where I had to create Xref tables creating the cross references.

Anyone any simple ideas 

As I say I am thinking extend form in X++ Aot and use this new Xref table as a filter when the Dropdown list is being rendered.

Would be rather nice if I could do a saved view in the Dropdown List where the user could pin it as a default.

Any help appreciated

Thanks

    Hi Siopold,

    You need to override the lookup method of dropdown2 control and add range to that with value of dropdown1 control.

    Refer to the below link which explains about the lookup methods and filtering lookups values.

    Hi,

    i assume, both the dropdown are available in same screen. In x++ we build dropdown using query (please see the link below for sample). if you want the second dropdown to render based on values picked from first drop down, the pass the value as a range to query.
