Treeview checkboxes with FormDecorator

[Phani Alla]

Hello, I have a treeview with OnClientNodeChecked event, I'm unable to check or uncheck the checkboxes in the tree. I have another tree which does not have an OnClientNodeChecked event, the checkboxes on this work fine, i'm able to check or uncheck.

Here is my OnClientNodeChecked event. each time I click on the checkbox the event is fired and it does return checked nodes, but i can't see them checked or unchecked on the UI. any help please?

function clientNodeChecked(sender, eventArgs) {
    var node = eventArgs.get_node();
    var tree = node.get_treeView();
    var checkedNodes = tree.get_checkedNodes();
    var radioNodes;
    for (var i = 0; i < checkedNodes.length; i++) {
        if (checkedNodes[i] != node) {
            if (checkedNodes[i].get_parent() == node.get_parent()) {
             if(checkedNodes[i].get_parent().get_attributes().getAttribute("radio")=="yes")
                oldNode = checkedNodes[i];
            }
        }
    }
    if (oldNode != null) {
        if (oldNode.get_parent() == node.get_parent()) {
            oldNode.set_checked(false);
            oldNode.set_expanded(false);
        }
        }
        node.set_checked(true);
        node.set_expanded(true);
        oldNode = node;
    }

thank you,

Hi Phani,

Please remove node node.set_checked(true); line as this node is already checked and it will work:

function clientNodeChecked(sender, eventArgs) {

var node = eventArgs.get_node();
var tree = node.get_treeView();
var checkedNodes = tree.get_checkedNodes();
var radioNodes;
for (var i = 0; i < checkedNodes.length; i++) {
if (checkedNodes[i] != node) {
if (checkedNodes[i].get_parent() == node.get_parent()) {
if(checkedNodes[i].get_parent().get_attributes().getAttribute("radio")=="yes")
oldNode = checkedNodes[i];
}
}
}
if (oldNode != null) {
if (oldNode.get_parent() == node.get_parent()) {
oldNode.set_checked(false);
oldNode.set_expanded(false);
}
}

// node.set_checked(true);
node.set_expanded(true);
oldNode = node;
}
