[Solved] Sorting the checked nodes in treeview

[pankaj]

Hi,

I am using RadTreeView control in radCombobox. I am using get_checkedNodes() method to get the checked nodes. This method is returning the collection of checked nodes but the order of the collection depends upon the values checked by user. I want this order in the order of index of the items in treeview. For example treeview is structured to have nodes A,B,C,D,E. If user checks in the order as D,B,C than collection returned is also in the order D,B,C. I want this collection in the order of index as B,C,D. Is there any way to sort this collection in javascript or to get the collection in the order of index. I am using 1 level depth of treeview control and I want this sorting in javascript.

Thanks,
Pankaj

Hi pankaj,

Since get_checkedNodes returns an array of RadTreeNode objects, so you could sort this array by Node Text, e.g.

function getSortedCheckedNodes() {
    var treeView = $find("<%= RadTreeView1.ClientID %>");

    var checkedNodes = treeView.get_checkedNodes();

    return checkedNodes.sort(sortNodes);
}

function sortNodes(a, b) {
    if (a.get_text() < b.get_text()) return -1;
    if (a.get_text() > b.get_text()) return 1;
    return 0;
}
