Children of DataItem

[Kazimierz]

Hi,
I have a static HierarchicalDataSource defined in a file. I use it as source for a TreeView. TreeView has an 'expand' event fired before expand actually occurs. In that event I can get dataItem related to the node that is being expanded. I need to get children of that dataItem but I cannot see any method/property on dataItem that would allow me to get them. Is there any way to get/load child items?

I would be most grateful for any help :)

Hello,

You can use the node children field to access the item child dataSource and its items e.g.

function expand(e) {
    var dataItem = this.dataItem(e.node);
    if (dataItem.hasChildren) {
        var childItems = dataItem.children.data();
    }
}

Regards,
Daniel
