How do you walk the tree from the selected node to
the last child within that branch?

TTreeNode* ChildNode = TreeView1->Selected;
while(ChildNode)
{
ChildNode->Selected = true;
String ss = ChildNode->Text;
TreeView1->SetFocus();
Sleep(1000);

ChildNode->GetNextChild(ChildNode);
}

This is my layout

ParentNode1
ChildNode1
ChildNode2
ChildNode3
ChildNode4
ChildNode5
ChildNode6
ChildNode7
ChildNode8

If i select ParentNode1, it must end up on ChildNode8, if i select
ChildNode3,
the last node that will highlight will be ChildNode5.

Not sure what i am missing, but my loop is not going anywhere to get
the result.


Thanks.

You need to provide more details. Given the example layout you mentioned
earlier, if you click on ParentNode1, should it do anything with ChildNode1,
ChildNode2, and so on, or just jump directly to ChildNode8? What EXACTLY do
you want to do with the walking?

ParentNode1
ChildNode1

ChildNode3
ChildNode4
ChildNode5
ChildNode6
ChildNode7
ChildNode8

ParentNode2
ChildNode1
ChildNode2
ChildNode3
ChildNode4
ChildNode5
ChildNode6
ChildNode7
ChildNode8

I want it to walk down each node in the following order. If i click
on ParentNode1,
it will go from ParentNode1, ChildNode1, 2, 3, 4, 5 ,6, 7, 8 and then
stop.
In the same way if i click on lets says ChildNode3, it will go to
ChildNode4, then
ChildNode5, then stop. Basically, it will go down each node of the
branch that
is attached to the Selected node.

There are two different ways to handle that:

1)
DoSomethingWithNode(TreeView1->Selected);

void __fastcall DoSomethingWithNode(TTreeNode *Node)
{
if( Node )
{
// do something with Node...

Node = Node->getFirstChild();
while( Node )
{
DoSomethingWithNode(Node);
Node = Node->getNextSibling();
}
}
}


2)
TTreeNode *Node = TreeView1->Selected;
if( Node )
{
TTreeNode *StopNode = Node->getNextSibling();
while( Node != StopNode )
{
// do something with Node ...
Node = Node->GetNext();
}
}
