[Solved] e.isValid on NodeDrop?

[Derek Hunziker]

Hello,

I am trying to alert my users before NodeDropped using the NodeDrop client event. It's working great, but I only need to alert when the drop is actually possible (I.E. when the "+" sign indicator appears on the dragged node).

Is there a way to determine if the drop target is valid? It seems as though you guys have already figured it out for the dragged node indicators?

Currently, I am using the following. It works, but I'm wondering if there's a more elegant solution:

function OnNodeDrop(e) {
    if ($('.t-drag-status').hasClass('t-add')) {
       //...
    }
}

Thank you!

-Derek

Hi Derek,

Great suggestion - we just implemented it and it will be available with the official release. If you want to have it right away, replace the isDropPrevented assignment in the onDrop function in telerik.treeview.js with:

var isDropPrevented =
        $t.trigger(this.element, 'nodeDrop', {
            isValid: !$dragClue.find('.t-drag-status').hasClass('t-denied'),
            dropTarget: e.target,
            item: $draggedElement.closest('.t-item')[0]
        });

Your Telerik points have been updated.
