Hi I am building a very large tree (about 320 nodes and 321 arrows between the nodes). The Flowchart.NET control seems to go belly up when I try this. Here are the problems I am seeing when I build the tree with a layout TopToBottom

The Horizontal scrollbar fails to show up. The vertical is the only one that shows. How can I make the horizontal scrollbar show? If I try zoomtofit I can see all the nodes in there but it doesnt let me scroll in normal view and look at all my nodes. here is my code I tried both with grouping and without grouping as you can see in the code. How can I fix this?

private void GenerateTree(Customer rc)
{
ArrayList al = rc.NetworkAsTree;
foreach(NodeData nd in al)
{
RootNode = CreateBox(nd.Node.Name);
//AssessmentTree.CreateGroup(RootNode);
GenerateNodes(RootNode, nd);
Rearrange();
}
AssessmentTree.RouteAllArrows();
}

private void GenerateNodes(Box Parent, NodeData nd)
{
foreach(NodeData nd1 in nd.Children)
{
Box b = AssessmentTree.FindBox(nd1.Node.Name);
if (b == null)
b = CreateBox(nd1.Node.Name);
//Group parentGroup = AssessmentTree.FindGroup(Parent.Tag);
//parentGroup.AttachToCorner(b, 0);
//AssessmentTree.CreateGroup(b);
AssessmentTree.CreateArrow(Parent, b);
Rearrange();
GenerateNodes(b, nd1);
}
}

private Box CreateBox(string Text)
{
Box b = AssessmentTree.CreateBox(0,0,30,10);
b.Text = Text;
b.Tag = Text;
return b;
}

private void Rearrange()
{
if (treeLayout == null)
{
treeLayout = new TreeLayout(RootNode,
TreeLayoutType.Cascading,
false,
TreeLayoutArrowType.Straight,
TreeLayoutDirection.TopToBottom,
10, 5, true, 10, 10);

}

treeLayout.Arrange(AssessmentTree);
}
