prevent id change on node selection

[Gaetano]

Hi, 
I found that kendo treeview automatically change  the id of a node when selecting that node..

example:

<ul class="k-group" style="">

    <li id="idItem1" class="k-item" data-uid="f15ccb0c-f3d8-4a56-bebd-e9d14d2dc877" role="treeitem">

        <div class="k-top">

            <span class="k-icon k-plus"></span>

            <span class="k-in">

                <span class="k-sprite folder"></span>Item1

            </span>

        </div>

        <ul class="k-group" style="display: none;">

            <li class="customClass k-item k-last" id="CustomId" data-uid="f244d97f-2adb-4e49-b40a-3766dd1eba92" role="treeitem">

                <div class="k-bot">

                    <span class="k-in">

                        <span class="k-sprite pdf"></span>Sub-Item1

                    </span>

                </div>

            </li>

        </ul>

    </li>

    <li id="idItem2" class="k-item" data-uid="8da3519c-27cd-49e6-a478-6e4cf1ccd3d0" role="treeitem">

        <div class="k-mid">

            <span class="k-in">

                <span class="k-sprite folder"></span>Item2

            </span>

        </div>

    </li>

</ul>

this is the default state; then if i select a node, its id change into

id="treeName_tv_active"

and once i select another node, its became just an empty field..

now, I saw that seems to be the "design" behavior for this control...
the problem is that if I can't get the Id of the node (I use this treeview to filter a listView and its pager).

I personally think that change the id of node is not a good behavior...I usually see some added classes to manage control's states...
Is there anyway of preventing this behavior?

Thanks

Hello Fabio,

You are right that the "treeName_tv_active" id is set to the selected items of the TreeView, but only if there is no user specified id for the current list item. I prepared the following JS Bin Example to demonstrate this. Notice how the "treeview_tv_active" id is set on every selected node, except the ones, where I have my custom id.

Hi Dimiter,
ok, I tried your example and it works fine..so I tried with my own tree and surprisingly It worked too...
I checked my version of kendo.all.js and it's v2012.3.1114, while I imagine you used the last one...
Could it be that this issue was present in my version and that it has been fixed in the last release?
Otherwise I cannot figure out why I have this issue in my code.

Thanks
Fabio

Hello Fabio,


Yes, this was an issue in version 2012.3.1114, but was fixed in 2012.3 1315. This is also described in the release notes:
"Fixed: The widget does not preserve the ID of the LI element"

You could find the rest of the changes and bug fixes here.
Wish you a great day.
