隐藏 WinForms TreeView 加号 [英] Hide WinForms TreeView plus sign

问题描述

我有一个带有一个主节点和几个子节点的 WinForms TreeView.

I have a WinForms TreeView with one main node and several sub-nodes.

如何隐藏主节点中的+(加号)?

How can I hide the + (plus sign) in the main node?

推荐答案

Treview 属性:.ShowRootLines = false

Treview Property: .ShowRootLines = false

当 ShowRootLines 为 false 时，加号/减号不会在根节点上显示，但必要时仍会在子节点上显示.

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.

在隐藏加号/减号的情况下，您可以考虑在树填充后执行根节点的 Expand() 方法.这将确保根节点显示所有一级子节点.

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.

注意:TreeView 上有一个 ShowPlusMinus 属性，但它适用于所有节点.

Note: There is a ShowPlusMinus property on the TreeView, but it works on all nodes.
