changing context mapping of a label at runtime

[Former Member]

Hi,

how can I change the context mapping of a label at runtime (by code)? I have a label and like to use it for displaying different "Model attributes" from different "Model Nodes" depending on some conditions.

Thanks a lot.

Regards,

Henning

In the IWDmodify view you can change the binding of any UI elements

IWDLabel lb1 = (IWDLabel) view.getElement("Label");

IWDAttributeInfo attrinfo = wdContext.getNodeInfo().getAttribute(IPrivateHelloWorldView.IContextElement.CA__SECOND);

lb1.bindText(attrinfo);

Hi Anoop,

sound like the solution I am looking for.

But how must I call the method out of my custom controller in detail?

I need to deliver some parameter values.

- IPrivateXSSPortalApplicationMainView wdThis

- IPrivateXSSPortalApplicationMainView.IContextNode wdContext

- com.sap.tc.webdynpro.progmodel.api.IWDView view

- boolean firstTime

But what must I pass to these varaiables in detail?

Thanks a lot.

regards,

Henning

com.sap.tc.webdynpro.clientserver.uielib.standrad.IWDLabel. is to be imported.

No particaular jar files to be added

you do one thing type IWD and after that press ctrl and space together...

you may get all the UI element type.

Hi,

Simply copy the code from Anoop post and past your WDModifyview() method

it showing some errors for that you can do simple ctrlshifto or right click the mouse there source->ogranizeImports might helps you.

there change your label name "Label" what u mention in the design of ur View.

thanks,

Lohi.

doModify will be inviked after each and every action in the view..

ok, that it is called on each action sounds good. Then there will be no need to call it from the controller.

But now I have another problem.

The type "IWDLabel" is unknown and can not be resolved. Even after trying to organize the imports.

Do I need to add a special import/external jar?

Thx.
