How to get all child nodes of selected parent?

 

Ultratree:

example scenario: 

parent

         child1

                 child3

                       child4

        child2

             child 5

 

how can I get all parent1 child nodes?????

thanks for any reply…..

 

 

 

tree.Nodes["parent"].Nodes will return the child nodes collection of the parent node. 

If you want all descendants, and not just the direct children, then you will need to walk down the tree recursively. 

void ultraTree1_AfterSelect(object sender, SelectEventArgs e)
{
    UltraTreeNode node = e.NewSelections.Count == 1 ? e.NewSelections[0] : null;
    if ( node != null )
    {
        List<UltraTreeNode> descendants = this.GetAllDescendants( node );
        bool stop = true;
    }
}

private List<UltraTreeNode> GetAllDescendants( UltraTreeNode node )
{
    List<UltraTreeNode> retVal = new List<UltraTreeNode>();
    this.GetAllDescendants( node.Nodes, retVal );
    return retVal;
}

private void GetAllDescendants( TreeNodesCollection nodes, List<UltraTreeNode> descendants )
{
    foreach ( UltraTreeNode node in nodes )
    {
        descendants.Add( node );

        if ( node.HasNodes )
            this.GetAllDescendants( node.Nodes, descendants );
    }
}
