<p>I have a WinForms TreeView with one main node and several sub-nodes.</p>
<p>How can I hide the + (plus sign) in the main node?</p>

Treview Property:
```
.ShowRootLines = false
```
When
```
ShowRootLines
```
is false, the Plus/Minus sign will not be shown for the root node, but will still show when necessary on child nodes.
With the Plus/Minus sign hidden, you might consider executing the
```
Expand()
```
method of the root node once the tree is populated.  That will make sure that the root node shows all first-level child nodes.
Note: There is a
```
ShowPlusMinus
```
property on the TreeView, but it works on
all
nodes.
