When I call the SetInteractive function it is setting the below value.
imageViewer.defaultInteractiveMode = new lt.Controls.ImageViewerZoomToInteractiveMode();
When I do I get back the following error message
Unable to get property 'parentNode' of undefined or null reference
my other functions like below are working fine.
imageViewer.zoom(lt.Controls.ControlSizeMode.fitWidth, 1, imageViewer.defaultZoomOrigin);
imageViewer.reverse = false;

Please see the attached code. I am able to set the default interactive mode without issue.
HTML:
Code:<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />

<!-- DIV to use as the container for the LEADTOOLS image viewer -->
<div id="imageViewerDiv" style="width: 600px; height: 600px; background-color: darkgray; float:left"></div>
</body>
</html>
JavaScript:
Code:var imageViewer;
window.onload = function () {
InitViewers();
LoadImages();
};
function InitViewers(){
var imageViewerDiv = document.getElementById("imageViewerDiv");
var createOptions = new lt.Controls.ImageViewerCreateOptions(imageViewerDiv);
createOptions.useElements = true;
imageViewer = new lt.Controls.ImageViewer(createOptions);
imageViewer.defaultInteractiveMode = new lt.Controls.ImageViewerPanZoomInteractiveMode();
}
function LoadImages(){
imageViewer.imageUrl = "Images/Cannon.png";
}
