Treelist prevent selection

[Philippe]

Hi everyone, I'm trying to implement a click validation on the selection event for the treelist.

All I've fount is this inspering article http://www.telerik.com/forums/disable-treeview-selection 

Claiming the preventDefault would do the job.

So I've tried placing an avent in Select and selectable with no succes.

change is the only event triggering

executing e.preventDefault does run that script inside Kendo.all.js

var preventDefault = function() {

   this._defaultPrevented = true;
};

then the trigger function "return e._defaultPrevented === true;"

 but it seem that your change function will not listen to it.

 _change: function() {

   this.trigger(CHANGE);
 },

 It seem like a bug

Am i missing anything?

Hello,

In order prevent selection you can handle the click event of the row in the treelist and remove the relevant css class:

$("#treelist").on("click", "tr[role='row']", function (e) {
                    if (//...some condition...//) {
                        var row = $(e.target).closest("tr[role='row']");
                        row.removeClass("k-state-selected")
                    }
                });
