Selective checkboxes in TreeView

[Trevor]

How can I recursively loop through _every_ TreeNode in a TreeView using
C#? The CheckBoxes property enables checkboxes for all TreeNodes. I
only want checkboxes on TreeNodes that have 0 child nodes. I don't know
how many levels deep the TreeView will be. I have the checkboxes part
under control but my code only loops through the root nodes of my
TreeView.

// My incorrect code

treeGroups.Chec kBoxes = true;
foreach (TreeNode node in treeGroups)
{
if (node.Nodes.Cou nt == 0)
TreeViewEx.AddC heckBoxToNode(n ode);
else
TreeViewEx.Remo veCheckBoxFromN ode(node);
}

Trevor,

Try something like this:

public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeCompo nent();

foreach( TreeNode node in treeView1.Nodes )
{
SetupTreeView(n ode);
}
}

private void SetupTreeView(T reeNode parentNode)
{
foreach( TreeNode node in parentNode.Node s )
{
SetupTreeView(n ode);

if( node.Nodes.Coun t == 0 )
TreeViewEx.AddC heckBoxToNode(n ode);
else
TreeViewEx.Remo veCheckBoxFromN ode(node);
}
}
