        // collapseCount is a custom variable
        var count = pane.collapseCount;
        if (count)
            count = count + 1;
        else
            count = 1;
        pane.collapseCount = count;
        var id = pane.get_id();
        if (id == "RadPane2") // RadPane
            pane.set_content("This pane has collapsed " + count + " times.");
        else // RadSlidingPane
            pane.setContent("This pane has collapsed " + count + " times.");
    }
</script>
