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(TreeNode node in trv_Directories.Nodes)
if(trv_Directories.GetChecked(node) !=
TriStateTreeView.CheckState.Unchecked)
GenerateModulesArray(node);

private void GenerateModulesArray(TreeNode nodes)
{
// Check to see if it's a single node
if(nodes.GetNodeCount(true) == 0)
if(trv_Directories.GetChecked(nodes) ==
TriStateTreeView.CheckState.Checked)
CompileModules.Add(nodes);
else
{
// Read the node and store into an arraylist
foreach (TreeNode node in nodes.Nodes)
{
if(trv_Directories.GetChecked(node) ==
TriStateTreeView.CheckState.Checked)
{
CompileModules.Add(node);
if(node.GetNodeCount(true) > 0)
GenerateModulesArray(node);
}
else if(trv_Directories.GetChecked(node) ==
TriStateTreeView.CheckState.GreyChecked)
{
if(node.GetNodeCount(true) > 0)
GenerateModulesArray(node);
else
CompileModules.Add(node);
}
}
}
}

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

private void RetreiveTreeView()
{
foreach(TreeNode node in CompileModules)
if(trv_Directories.Nodes.Contains(node.FullPath))
trv_Directories.SetChecked(node,
TriStateTreeView.CheckState.Checked);
}
On form_LOAD event:

// Check to see if the array is already populated
if(CompileModules.Count > 0)
RetreiveTreeView();

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

Somebody can help me with that?

Thanks!
