How to pass information from one SAP standard webdynpro component to another?

On the click of the tabs in one SAP standard webdynpro component, we want to display some help text in the vertical navigation strip which is in another SAP standard Webdynpro component?

hi Sandeep ,

hv u folowed these steps :

// component B using component A

1 in the component B , Double click the component in the object tree and choose the tab Used Components.

2 Define a usage of your component A within this component.

3 Do a mapping between the interface controller of ur MAIN component B & the component controller of

ur SUB component A 4 Before you can call the Interface Controller method of the used component in ur view ,you have to declare that the view controller can use the Interface Controller of the used component. By default only the component controller can access used components directly, view controllers have to specify this explicitly.

5 go to the tab Properties of the B, click the button Create Controller Use and select the INTERFACECONTROLLER of the component A for component use .

6 go to WINDOWS , inside ur View container right clck to select embed view to select the view to be embedded

n hv u refered this article on component usage :

hi,

Use the concept of Assistance Classes.

REfer teh SAP Online help :

http://help.sap.com/saphelp_nw70/helpdata/EN/43/1f6442a3d9e72ce10000000a1550b0/frameset.htm

Use the Same Assistance class in all the components and set an Attribute in Assistance class with the information while in One Component.

Now in your 2nd Component , you can access that Attribute of Assistance class and check the value set.

To call the attribute/method use the instance wd_assist.
