Aaccessing view elements in view coding

[Former Member]

Hi all,

I want to access view element attributes in coding beyond the static wdDoModifyView method. This method has a paremeter "view" (type com.sap.tc.webdynpro.progmodel.api.IWDView) which gives me access to element attributes via view.getElement(<name>).

Is it possible to access this IWDView object in view coding outside of method wdDoModifyView?

Hi Michael,

You can store view variable in context BUT it is hardly recommended to avoid doing this - try to redisign your logic.

Armin, isn`t it your opinion on this: :

<i>

No, this is bad advice. UI element instances should only be referenced in wdDoModifyView(). To change properties from event handlers, use data binding.

Do not store the IWDView reference in the context for accessing UI elements from event handlers.

Hello Maksim,

you got me wrong. I asked "why" on the original posters question.

I wonder why he wants to access view elements for getting property values because he should use data binding for this.
