Hi,

You can use the visibility property of the Group Element to make it invisible.

In the doModifyView

get the object of the 4th and the 5th element.

Based on a condition

IWDGroup grp4 = (IWDGroup) view.getElement("Group4");

grp4.setVisible(WDVisibility.NONE);

or

grp4.setVisible(WDVisibility.BLANK);

This should make the group not visible

Hope this solves your problem.

Hi RK,

Just to add to Prakash's answer,

before the if condition, first set the Visibility to VISIBLE. This will ensure, if the condition changes in the view, in the next reload of the view you can see the Group.

grp4.setVisible(WDVisibility.VISIBLE);

Also there is a difference between WDVisibility.NONE & WDVisibility.BLANK

WDVisibility.BLANK will display an empty area depending on the size of the Group.

WDVisibility.NONE will not display anything on the view.

If you want to manipulate the visibility in this way, don't use wdDoModifyView() but use data binding.

Just to add to Armins answer.

Create a data element in the context of type Visibility, which is available under

Dictionary Simple Type
 |_ Local Dictionary
     |_ com.sap.ide.webdynpro.uielementdefinition.Visibility

then you bind the visibility property of the group to your newly created context element, and updates the visibility of the element in the action method of your button.

This is the prefered way, since it provides a cleaner design.
