Thanks. The cellrenderer function approach solves issue #2. I still have issue #1. when I dynamically increase the font size through a click event. Here’s what happens. I see the font size increase and a split second later it reverts to the original size.

Here is the click handler for the increase button size event. When called with up === true doesn’t work. When called with up === false works fine.

function changeFontSize(up) {
	var newSize;
	if (up) {
		newSize = currentFontSize * SIZE_FACTOR;
	} else { // must be down
		newSize = currentFontSize / SIZE_FACTOR;
	}
	$("#current_question").css("font-size", newSize );
	$("#current_answer").css("font-size", newSize);
	// as per jqWidgets documentation.
	$(".jqx-grid-column-header").css("font-size", newSize);
	$(".jqx-grid-cell").css("font-size", newSize);
	$("body").css("font-size", newSize);
	currentFontSize = newSize;
}

Thanks for pointing out the html error. You made me think about the initialization process and the critical error in initContent was setting ‘source: null’ for the jqxTree. Once I deleted that line things starting working as I expected. Thanks for the feedback.
