I've been exploring the dark alleyways of the Windows Presentation Foundation this week and found no way in my trawlings of the net to expand a treeview to a specific node.
No FindNode, no ExpandTo or ExpandAll. Great.
Anyway, here's the solution I came up with. It relies upon a binding the Tag property to the text you are searching for, but that could obviously be changed.
void jumpToFolder(TreeView tv, string node)
{
bool done = false;
ItemCollection ic = tv.Items;
while (!done)
{
bool found = false;
foreach (TreeViewItem tvi in ic)
{
if (node.StartsWith(tvi.Tag.ToString()))
{
found = true;
tvi.IsExpanded = true;
ic = tvi.Items;
if (node == tvi.Tag.ToString()) done = true;
break;
}
}
done = (found == false && done == false);
}
}
