Get parent tree node in nodeClick client event ASP.NET MVC

How do you get the parent tree node in the nodeClick JavaScript event? And, where is the documentation source for this information?

Here is my tree with the nodeClick client event:

@(Html.Infragistics().Tree()
    .ID("FilterTree")
    .Bindings(b1 =>
    {
        b1
        .ValueKey("Value")
        .TextKey("Text")
        .ImageUrlKey("Base64ImageUrl")
        .ChildDataProperty("ChildItems");
    })
    .DataSource(Model.TreeListItems)
    .DataBind()
    .ClientEvents(new Dictionary<string, string> { { "nodeClick", "FilterTreeNodeClicked" } })
    .Render()
)

Here is my JavaScipt event:

function FilterTreeNodeClicked(evt, ui) {

    // This is NOT the tree node. Instead, it looks like a DOM element
    var ParentNode = $("#FilterTree").igTree("parentNode", ui.node.element);

    // I need the parent for ui.node

}

Hello Ray,

Thank you for your patience while I was looking into this matter for you.

Indeed the parentNode method returns a jQuery node element. However, having this element, you can use the nodeFromElement method of igTree in order to get the node object of the parent:

function FilterTreeNodeClicked(evt, ui) {
    var parentNodeElement = $("#tree").igTree("parentNode", ui.node.element);
    var parentNodeObject = $("#tree").igTree("nodeFromElement", parentNodeElement);
}

I believe you will find the following documentation regarding the igTree control very helpful:

– API reference

– Help topics

– Online samples

Please do not hesitate to contact me if you need any further assistance with this matter.

To get the parent tree node in the nodeClick client event in an ASP.NET MVC application using the Ignite UI for jQuery Tree (igTree), you can use the parentNode method. The parentNode method allows you to retrieve the parent node of the clicked node.

In your code, you correctly identified the parentNode method, but it's important to understand how to access the ui.node element correctly, as ui.node represents the tree node object, not a DOM element directly.
