How to calculate the number of displayed rows in a repeat control

In my XPages application I am displaying a list of objects via the xp:repeat control.

I also use the xe:pagerAddRows control to add an X numbers of rows to the repeat control.

In the text of the xe:pagerAddRows control I want to display how many more items there are. Therefor I need to know the number of rows currently displayed in the repeat control.

How must I do this?

Solution

  • I am using this:

    var text = strings["btn_show_more"]
var dv = getComponent('rptHistory');
return text + " (" + (dv.getRowCount() - dv.getRows()) + ")";
