Hi Naga,

1) Under your context, create attributes of type "visbility". (create an attribute and change it's type to Local Dictionary -> com.sap.ide.webdynpro.uielementdefinitions->Visibilty)

2) Bind the Visbility property of the required UI element to this attribute.

3) When required chnage the visbilty as below:

WDContext.currentContextElement().set<attribute name>(WDVISIBILTY.VISBILE);

/* Makes the UI element visible */

WDContext.currentContextElement().set<attribute name>(WDVISIBILTY.BLANK)

/* Makes the UI element invisbile , but it takes up the space on the screen */

WDContext.currentContextElement().set<attribute name>(WDVISIBILTY.NONE)

/* Makes it invisible and doesn't take up space too */

Hope this helps,

Best Regards,

Hi,

You can make use of LifeCycle property of a component.

While adding the components in the used components you can specify the lifecycle. Set the property to "CreateOnDemand" so that you can control the creation of the component.

I really didn't understand what you meant by <i>VISIBILITY</i> of a component. However, if you want to control the lifecycle of a component then, you may do that by using the <i>"Life Cycle"</i> property of a Used Component. You may set it to <i>"Create on demand"</i>(default/automatic control over the lifecycle -- taken care by WDruntime) or <i>"Manual"</i>(To create and destroy manually).
