AW: dataScroller

[andreas.mitter]

Another possible is that you set the rendered attribute of the datascroller  to false or true at the point where you get your list for the datatable in the backing bean.

e.g something like that in your backing bean:

 

rowList is the result you will display on the datatable. In my example a datascroller will only be displayed if the list contains more than 5 items.

 

 if (rowList.size() > 5) {
    dbAdminDto.setShowDatascroller(true);
   }
   else {
    dbAdminDto.setShowDatascroller(false);
   }

 

 

in the JSP:

<t:dataScroller...

    rendered="#{dbAdminDto.showDatascroller}"

...

/>

 

I hope it's clear, what I mean...

 

Regards

Andy

Betreff: dataScroller

I'm trying to render a dataScroller only when the number of rows of the table are greater than rows exibited on a page.
I tried this :  rendered="#{((rowsCount>displayedRowsCountVar) ? true : false)}" , but the dataScroller is not displayed, despite the number of rows.
