Parent node value is not included in the selected items about ngx-treeview HOT 11 CLOSED

please get some example to get parent value(Id) in items. I think, It's very important for all developers.

Parent (value: 1) -- I need this value, but I think this component doesn't have such functionality.
--Child 1 (value: 2)
--Child 2 (value: 3)

from ngx-treeview.

Question 1: using TreeviewEventParser like in my example 5 https://leovo2708.github.io/ngx-treeview/. You can get list of checked from root to leaf.

Question 2: Yes, you can. You can update checked of your TreeviewItem object. But it will not update checked of parent, you must do this yourself. You should write a helper to handle this.

Thanks for quick resposne @leovo2708.
Yes, #1, I was thinking about create a custom TreeviewEventParser to return a flat list of selected items.
About #2, can you give an example?
What I was thinking is in TreeviewItemComponent

onCheckedChange = (skipChildrenCheck) => {
        const checked = this.item.checked;
        if (!_.isNil(this.item.children)&& !skipChildrenCheck) {
            this.item.children.forEach(child => child.setCheckedRecursive(checked));
        }

        this.checkedChange.emit(checked);
    }
    onChildCheckedChange(child: TreeviewItem, checked: boolean, skipParentUpdate) {
        if (this.item.checked !== checked && !skipParentUpdate) {
            let itemChecked = true;
            for (const tmpChild of this.item.children) {
                if (!tmpChild.checked) {
                    itemChecked = false;
                    break;
                }
            }

            this.item.checked = itemChecked;
        }

        this.checkedChange.emit(checked);
    }

I tried to override the onCheckedChange and onChildCheckedChange but the component is not exported from the lib so not so sure how I can achieve this.

If I support option {disabled: true, checked: false} for item ReactJS, does it rescue you?

I think you can use itemTemplate. It can help you.

from ngx-treeview.

@leovo2708 I need a way to emit this event this.checkedChange.emit(checked); using itemTemplate without calling onCheckedChange and onChildCheckedChange.
I think this requires a minor change in TreeviewItemComponent and TreeviewItemTemplateContext.

Please help me to create pull request. Thanks.

Published in new version 1.2.2.

Hi,
"selectedChange" event has been fired when selecting Parent but the $event array is empty. But the expected would be event array with Parent node value.
I guess the problem is with binding the selected node in ngmodel

Its working as expected when I select child nodes. I'm using the latest verion 1.2.3.

Parent and child nodes can be selected independently by setting decoupleParentChild= true in the config.

same issue please let me know if it's fixed
