[Solved] Get the item value from clicked checkbox

[Pedro]

Hi all,
How can I get the item value based on the clicked checkbox?
I need to filter a grid based on the clicked chebox in the treeview (I'll do this using json).

Regards,
Pedro

Hello Pedro,

If you are subscribed to the onChecked client-side event, you can use the following script to get the item value:
    var treeview = $('#TreeView').data('tTreeView');
    var value = treeview.getItemValue(e.item);

If you want to get the values of all checked treeview items, you can use the following:
    var $treeviewElement = $('#TreeView1');
    var treeview = $treeviewElement.data('tTreeView');
    var values = [];
    $treeviewElement.find(':checked').each(function() {
        var item = $(this).closest('.t-item');
        values.push(treeview.getItemValue(item));
    });
    // values is now an array that contains all checked items' values

Thank you Alex, but I dont have the onChecked event in the TreeView (I think i'm using a old version of the control). :(
Can I update the control? (I'm not using the .Net 4 framework)
Is This the best choice?

Cheers,
Pedro

Well... I did it my way. :)
I put a code to get all the treeview checkboxes and put a click event to fire a post using json.
Like this:
 

 $(document).ready(function () {
        $("#treeview").find("li").find("div").each(function (index, item) {
            var cb = $(item).find(':checkbox');
            $(cb).click(function () {
                if (cb.attr("checked")) {
                    jsonPost(cb, item, true);
                } else {
                    jsonPost(cb, item, false);
                }
            });           
        });       
    })

 

 

I hope this help somebody.

Cheers,
Pedro
