Hi,

Create an attribute of type com.sap.ide.webdynpro.uielementdefinitions.Visibility

Map this attribute to the visible property of the table.

Initially set this to WDVisibility.NONE and inside the action handler set this to WDVisibility.VISIBLE.

Ex:

If your attribute name is TableVisibility then

In the init

wdContext.currentContextElement().setTableVisibility(WDVisibility.NONE);

In the button action Handler

wdContext.currentContextElement().setTableVisibility(WDVisibility.VISIBLE);

Hi Nisha,

Create button and Table say "TableID" in the view

(1) Keep a global boolean variable say "showTable".

(2) in the action of button click set this variable as true.

(3) Now in wdDoModifyView method:

IWDTable table=(IWDTable) view.getElement("TableID") ;

if(showTable){

table.setVisible(WDVisibility.VISIBLE);

}else{

table.setVisible(WDVisibility.NONE);

}

Now your problem is solved.

By "global", you mean static, yes? Then this is bad advice.

Hi Armin,

I accept it, it's a bit misleading. At the beginner's perspective it's not good. But with

Global, the sense was :- you can create a boolean context variable, which value you can set on the action of button.

Hi,

To toggle I guess this should be a better approach.

WDVisibility currentStatus = wdContext.currentContextElement().getVisibility() //Visibility is a context attribute created of type WDVisibility mentioned above

if ( currentStatus.equals(WDVisibility.VISIBLE) )

wdContext.currentContextElement().setVisibility(WDVisibility.NONE);

else

wdContext.currentContextElement().setVisibility(WDVisibility.VISIBLE);

Dont forget to initialize the context variable to a default value either NONE/VISIBLE.

It has nothing to do with "beginners perspective". Using a static variable here will break your code because it is not thread-safe. The data binding solution is the way to go.

It is safe here to compare using "==".
