OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

[Former Member]

Hi Experts

We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.

Rrgards,

Srikanth.

Hi Srikanth.

Try this...

Bind the VISIBLE property of all UI elements/fields you want to hide to a context attribute of type WDUI_VISIBILITY. now, in the onSelect method of DropDown, when the value changes to a desired value, Set the value of context attribute WDUI_VISIBILITY to '02'. This should make the feilds hidden.

Thanks,

Hi

Thanks for your quick reponse. However, this is not a Dropdown box that is placed on the screen. This is a part of the Selection Screen which is generated dynamically by the webdynpro.

Well, the OnSelect event doesn't exist and hence it is not possible.

There are some events on the select options component to which you can bind your own handlers:

ON_CANCEL

ON_CHECK

ON_ENTER

ON_EXECUTE

ON_OVS

ON_RESET

try some of those. I don't see any on_select, but maybe the on_enter event works too?

Hi

THanks for the information. However, I am specifically looking for On_Select event of the dropdown menu.

Hi Srikanth,

as you seem to be already aware, the component is dynamically built.

so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.

What is it about this that you particularly want help with?

Cheers,

Chris
