Code to creating Radio Button

[Former Member]

Hi All,

We are trying to create Radio Button UI Element dynamically.

IWDTransparentContainer container = (IWDTransparentContainer) view.getElement( "RootUIElementContainer");

IWDRadioButton radiobutton = (IWDRadioButton)view.createElement(IWDRadioButton.class, "MyRadioButton");

container.addChild(radiobutton);

This is the code we are using. We have craeted 2 context attributes and set the KeyToSelect and SelectedKey properties to it.

radiobutton.setKeyToSelect("radiooptions.male");

radiobutton.setSelectedKey("radiooptions.common");

Now for setting teh default radio button we gave this,

wdContext.currentRadiooptionsElement().setMale(1);

wdContext.currentRadiooptionsElement().setCommon(1);

But its giving an error:

com.sap.tc.webdynpro.progmodel.context.ContextException: Path null does not point to an attribute, but to com.sap.tc.webdynpro.progmodel.generation.DelegatingView@e6846b

And if we dont give the context and just create a radio button, the radio button comes as greyed out, even the text that we set is coming greyed out.

Please help me out with this...

Regards,

Becky.

Hi u can put this method in the component controller.

Call this method in wdinit() of the view.

public void populateValues( )
  {
    //@@begin populateValues()
    try
    {
    	
		/*****POPULATING RADIO BUTTON**********/
		
		IWDAttributeInfo a2=wdContext.getNodeInfo().getAttribute(IPublicNewTestComp.IContextElement.RADIO);
		ISimpleTypeModifiable stm2=a2.getModifiableSimpleType();
		IModifiableSimpleValueSet svs2=stm2.getSVServices().getModifiableSimpleValueSet();
    	
		svs2.put("A","First");
		svs2.put("B","Second");
		
		/**************************************/
    }
    catch(Exception e)
    {
    	msgMngr.reportException("In populateValues "+e,false);
    }
    //@@end
  }

Can you give more details on the use-case? Why do you need to create radio buttons by code?

Maybe you can just use a radio button group defined at designtime?

Hi

I think this problem is ocurr becouse you missed some bindings of your UI element or the context mappings. Check for the same. Or try to delete that dropdownbyindex element and test application. Then insert new dropdown element once again, bind all required properties and then test.

Thanks
