I try implement Kendo UI PanelBar (see http://demos.kendoui.com/web/panelbar/images.html) If I open some items (Golf, Swimming) and next click to "Videos Records", I have expanded items. But when I do refresh page (click on some link), all expanded structure is lost.
On KendoUI forum I found, that I can get only possition of selected item and after reload page I must calculate all noded. Is there any way, how can I have expanded items in my situation? If do not need, I don't want to use the html frames.
Best regards, Peter
Thank you for your answer, was very usefull. I add here code of skeleton of jQuery which remember 1 selected item now. Required add jquery.cookie.js [https://github.com/carhartl/jquery-cookie]
function onSelect(e) {
var item = $(e.item),
index = item.parentsUntil(".k-panelbar", ".k-item").map(function () {
return $(this).index();
}).get().reverse();
index.push(item.index());
$.cookie("KendoUiPanelBarSelectedIndex", index);
//alert(index);
}
var panel = $("#panelbar").kendoPanelBar({
select: onSelect
}).data("kendoPanelBar");
//$("button").click(function () {
// select([0, 2]);
//});
function select(position) {
var ul = panel.element;
for (var i = 0; i < position.length; i++) {
var item = ul.children().eq(position[i]);
if (i != position.length - 1) {
ul = item.children("ul");
if (!ul[0])
ul = item.children().children("ul");
panel.expand(item, false);
} else {
panel.select(item);
}
}
}
// on page ready select value from cookies
$(document).ready(function () {
if ($.cookie("KendoUiPanelBarSelectedIndex") != null) {
//alert($.cookie("KendoUiPanelBarSelectedIndex"));
var numbersArray = $.cookie("KendoUiPanelBarSelectedIndex").split(',');
select(numbersArray);
}
else {
// TEST INIT MESSAGE, ON REAL USE DELETE
alert("DocumenReadyFunction: KendoUiPanelBarSelectedIndex IS NULL");
}
});
