TreeNodes collection

[Ferrari.NET]

Hi all

I have a treeview in a form that I need to store inside a nodes
collection so I'll not loose the values when I change between screens.

What I'm doing is store all the checked nodes into a ArrayList and then
retreive them:

// Generate the arraylist with the modules that are checked
foreach(TreeNod e node in trv_Directories .Nodes)
if(trv_Director ies.GetChecked( node) !=
TriStateTreeVie w.CheckState.Un checked)
GenerateModules Array(node);

private void GenerateModules Array(TreeNode nodes)
{
// Check to see if it's a single node
if(nodes.GetNod eCount(true) == 0)
if(trv_Director ies.GetChecked( nodes) ==
TriStateTreeVie w.CheckState.Ch ecked)
CompileModules. Add(nodes);
else
{
// Read the node and store into an arraylist
foreach (TreeNode node in nodes.Nodes)
{
if(trv_Director ies.GetChecked( node) ==
TriStateTreeVie w.CheckState.Ch ecked)
{
CompileModules. Add(node);
if(node.GetNode Count(true) > 0)
GenerateModules Array(node);
}
else if(trv_Director ies.GetChecked( node) ==
TriStateTreeVie w.CheckState.Gr eyChecked)
{
if(node.GetNode Count(true) > 0)
GenerateModules Array(node);
else
CompileModules. Add(node);
}
}
}
}

And then when I get back to the screen I do this:

private void RetreiveTreeVie w()
{
foreach(TreeNod e node in CompileModules)
if(trv_Director ies.Nodes.Conta ins(node.FullPa th))
trv_Directories .SetChecked(nod e,
TriStateTreeVie w.CheckState.Ch ecked);
}
On form_LOAD event:

// Check to see if the array is already populated
if(CompileModul es.Count > 0)
RetreiveTreeVie w();

It gets inside the RetreiveTreeVie w routine, but the Contains method is
not finding the nodes.

Somebody can help me with that?

Thanks!
