The AddClass function does not work properly in the Kendo Tree View after the RemoveClass function, especially when selecting the same node

Hey there, I am currently working with a kendoTreeView and trying to set up an action triggered by clicking on the same selected node. To achieve this, I incorporated the following code in the change event:

change : function(e) {
                        $("#DT-DICT-treeview").data("kendoTreeView").select()
                                            .find("span.k-state-selected")
                                            .removeClass("k-state-selected");
                                }

While this solution worked perfectly, I noticed that the background color of the selected node became transparent. To address this issue, I created a new class with the same CSS properties as the selected node and added it upon each change event. Initially, this fix seemed to work fine for the first selection, but it failed to do so on subsequent selections.

If you'd like to see an example, feel free to check out this jsFiddle link.

Here are the steps to replicate this issue:

1) Select node DT1: It turns blue

2) Select node DT2: DT1 returns to normal while DT2 becomes blue

3) Attempt to select DT1 again: Doesn't seem to be functioning anymore

Your assistance will be greatly appreciated. Thank you!

Answer №1

It is important to note that altering the k-state-selected class manually will disrupt the functionality of the plugin. Instead, adjust the styling without interfering with the selection class already in place.

http://jsfiddle.net/TrueBlueAussie/syg9746k/1/

For example, create custom CSS styles targeting the specific additional class:

.k-treeview .k-in.k-state-selected.k-selected-treeView-active {
    background-color: #428bca;
    color: #fff;
    background-image: none;
}

To enhance specificity, use Chrome to identify selectors for properties like border, hover, etc., and include your own CSS styles incorporating .k-selected-treeView-active.
