Hi,

Please try the following JavaScript code:

var $ = $telerik.$;

function pageLoad() {
    var treeView = $find("<%=RadTreeView1.ClientID %>").get_element();
    var rtMinus = $(treeView).find('.rtMinus');
    var rtPlus = $(treeView).find('.rtPlus');

    rtMinus.on("mouseover", function myfunction(e) {
        this.click();
    });

    rtPlus.on("mouseover", function myfunction(e) {
        this.click();
    });
}

I made you a video, showing how this custom code works at my side.

Hope this would be helpful.

rtMinus.mouseover(function myfunction(e) {
            this.click();
        });
     
        rtPlus.mouseover(function myfunction(e) {
            this.click();
