function ClickHandler(sender, args) {
 
 
 
		   isChecked = args.get_item().get_row().get_cell(0).get_element().children[0].checked;

I get an error message stating that "Microsoft JScript runtime error: Object doesn't support property or method 'get_item'

I am sorry, but it just doesn't work for me.

I have implemented the script as instructed. But the check box click event is not firing.

If doesn't change the child node check boxes.

I will play with it some more, but it just isn't working with my templated controls.

Hello Daryl,

Provide me with an isolated sample project and I will be happy to assist you finding what is causing the issue.

Could you try what I sent you but wrap it in a webtab? Could that have an effect.

Okay, I have given up on this and gone to using the built in check boxes.

Now I need to use autocheck, which works, but, when I click a child I don't want the parent changed. I only want it to work when I click the parent then update all the children.

Hi Daryl,

You could achieve such behavior using the following script for NodeChecking client side event:

var checkState = 0;

function WebDataTree1_NodeChecking(sender, eventArgs) {

    var node = eventArgs.getNode();

    checkState = (node.get_checkState() == 0) ? 1 : 0;

    setChildrenCheckState(node);

}

function setChildrenCheckState(parentNode) {

    if (parentNode.hasChildren()) {

        for (var i = 0; i < parentNode.get_childrenCount(); i++) {

            parentNode.get_childNode(i).set_checkState(checkState);

            if (parentNode.get_childNode(i).hasChildren()) {

                setChildrenCheckState(parentNode.get_childNode(i));

            }

        }

    }

}

In order for this to work, you should set EnableAutoChecking to false.

Let me know if you have any questions regarding the matter.

I'm glad I could help.

Feel free to contact me if you have any further questions.

You sir, Are my hero.

Thanks!
