How to join the information out of two nodes

[Former Member]

Hi,

I´ve got a little problem. I created a dropdown field which shows me the data of a specific column of a table. The table is filled by many nodes. My problem is, that I want to show more than one column in the dropdown field. For example: The columns are name and city and I can see and select the name in the dropdown field. The city will also change after my selection, but I want to see it before I select a name. Is there a way to show more than one node in a dropdown field? So that I could see the name an the city which belongs to it.

Hi Andreas,

An option is to use EVS. create a simpletype attribute (at design time or at runtime) and create key-value data for it. Let the key be name and the value be the city. Now if you bind an input field to this attribute , a value help will be available to you which will show both the name & the city. But the disadvantage is that the user can eneter his own custom values too. Therefore a check needs to be done for the same.

If you need more information on creating EVS, this document will help you. https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/va... help in web dynpro applications.pdf

If you need more info on populating the node dynamically, search this forum using the keywords 'dropdownbykey' and 'populate'.

Hope this helps,

Best Regards,

Nibu.
