[Solved] In treeview, how to know if parent checkbox is checked from child node

[Jon]

Hi,

I have a question in MVC Treeview checkbox.
My tree looks like this:

root
        level 1
                level 11
                level 12
                level 13


In my program, I check the "level 11" node, and would like to know if its parent node "level 1" is check or not. I use the following logic in my code (onCheck method) but it deos not work. Please help. Thanks.

var

 

 

childrenChecked = $('#NoteTreeView > ul.t-group > li.t-item > ul.t-group > li.t-item:has(ul.t-group)').find("*:checkbox:checked").length;

 

if ($(this).parent().checked) {

   childrenChecked = childrenChecked - 1;
}

Hi Jon,

Here is how to check if the parent node is checked:

function onChecked(e) {
    var parentItem = $(e.item).parent().closest('.t-item');
    var isParentChecked = parentItem.find(':checkbox:first').is(':checked');

    alert(isParentChecked ? 'parent is checked!' : 'parent is not checked!');
}
