    I have a 3 level tree.

    Category a
    - Sub Category a1
    --sub sub category a11
    --sub sub category a12
    --sub sub category a13
    Category b
    - Sub Category b1
    --sub sub category b11
    --sub sub category b12
    --sub sub category b13

    I want to expand only the first 2 levels like...
    Category a
    +Sub Category a1
    Category b
    + Sub Category b1

    How would I do this?  I am using a database to pull in the values and relationships.

    Thanks, Marty

    EDIT: I found the solution in the forum

    protected void RadTreeView1_NodeDataBound(object sender, RadTreeNodeEventArgs e)
            //root nodes only
            if (e.Node.Level == 0)
                e.Node.Expanded = true;
