Hi,
I'm actually evaluating the JSF-Controls for our Product, so I'm not very experienced with NetAdvantage.
Is there a way to call clientside Javascript-functions when an item is getting selected in a treeView.
I managed it to define some ActionListeners in my ControllerBeanfor my treeNodes, but I can't call any JS-Functions.
ELContext elContext = context.getELContext(); MethodExpression exprActionListener = application.getExpressionFactory().createMethodBLOCKED EXPRESSION.
Thanks in advance ,Mike
Hi Roshan,
the two functions didn't make a difference.
But in the meantime, I've contacted the Infragistics Developer Support directly and they told me that there is a bug in the WebTree and they search for a resolution.
I will let you know what they find out if you are interested.
Thanks a lot,
Mike
Hello Mike,
I am not sure about that.. Have you added following script in your application?function myAjaxRequesting(sender, args) {}
function myAjaxResponseCompleted(sender, args) {}
I am not sure if it could be the reason but you can give it a trial. In case if you still have problem..Then try to provide small size code of your application here (beans, and JSP). I will look into this and try to find out the reason.
Thank you.Roshan
Hello Roshan,
thanks again for your time.
I tried the tree from your example and it worked fine, but when I try to create the nodelist in my bean my tree still disappears. (example from my previous post).
Do you have any idea what I am doing wrong or is the CSOM-feature not working with beans?
I cheked and found no issue while working with CSOM for TreeView. Following is the sample JSP which I test this:
<%@ page language="java" pageEncoding="ISO-8859-1"%><%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%><%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%><%@ taglib uri="http://es.infragistics.com/faces/netadvantage" prefix="ig"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><title>My JSF 'TreeViewTest.jsp' starting page</title><script>
function nodeExpanded(sender, args) { alert("Node Expanded");}
function nodeClick(sender, args) { alert("Node Clicked");}
function myAjaxRequesting(sender, args) {}
</script></head><body><f:view><h:form><ig:treeViewstyle="border: 1px solid silver; height: 200; width: 300">
<ig:treeViewClientEvents nodeExpanded="nodeExpanded"nodeClick="nodeClick" /> <ig:treeNode id="treeNode1" value="My Computer"iconUrl="/resources/myComputer.gif">
<ig:treeNode value="Local Disk (C:)"iconUrl="/resources/localDisk.gif">
<ig:treeNode value="Folder 1"><ig:treeNode value="Folder 1-1" />
<ig:treeNode value="Folder 1-2" /></ig:treeNode>
<ig:treeNode value="Folder 2"><ig:treeNode value="Folder 2-1" /><ig:treeNode value="Folder 2-2" /></ig:treeNode></ig:treeNode><ig:treeNode disabled="true"value="CD Drive (D:) --> (disabled node)"iconUrl="/resources/cdDrive.gif" /><ig:treeNode value="Control Panel"iconUrl="/resources/controlPanel.gif"><ig:treeNode value="Fonts" iconUrl="/resources/fonts.gif" /><ig:treeNode value="Network Connections"iconUrl="/resources/networkConnections.gif" /><ig:treeNode value="Printers and Faxes"iconUrl="/resources/printersFaxes.gif" /><ig:treeNode value="Scheduled Tasks"iconUrl="/resources/scheduledTasks.gif" /></ig:treeNode></ig:treeNode><ig:treeNode id="treeNode2" value="My Network Places"iconUrl="/resources/myNetworkPlaces.gif"><ig:treeNode value="Entire Network"iconUrl="/resources/entireNetwork.gif" /><ig:treeNode value="www.sun.com (redirect to the page)"href="http://www.sun.com" /></ig:treeNode></ig:treeView></h:form></f:view></body></html>
The expand and click event are triggerd without any issue. There is no any beans used here so you can check this easily.
Hope it helps you.
Roshan
I could not get time to have a look for this. I will let you know as I get chance for it..
