ExpandAllItems with NeedDataSource

[Derek]

I need to begin the treelist with all nodes expanded, and then allow to expand/collapse as needed. I use NeedDataSource for the expand collapse, but the list starts off collapsed by default and I can't use ExpandAllItems() because I'm assuming it used a type of databind method that won't work with the NeedDataSource event. Is there a way to accomplish what I need?

Thanks, 

Derek

Hello Derek,

NeedDataSource event can be used for binding the TreeList. One suggestion is you can expand the treelist in pageload as shown below.
C#:

protected void Page_Load(object sender, EventArgs e)
{
    RadTreeList1.ExpandAllItems();
}

Perfect. Thanks, Shinu.
