添加后如何从树视图中删除图像
使用 Visual Studio 2010 和 C#，我有一个树视图，并向每个节点添加了图像。回想起来，我现在想要删除与 3 个主根节点的子节点关联的图像。如何从 3 个主根节点的子节点中删除图像，但将图像保留在 3 个根节点上？
我尝试打开节点的属性，并将所有子节点的 ImageIndex 和 SelectedImageIndex 更改为“none”，当我按“确定”时，它仍然显示每个子节点的默认图像。
谢谢
Using visual studios 2010 and c# i have a treeview and i added images to each of the nodes. In retrospect i now want to remove the images that are associated with the children of the 3 main root nodes. How do i remove the images from the children of my 3 main root nodes but keep the images on the 3 root nodes?
I have tried opening the properties for the nodes and changed the ImageIndex and SelectedImageIndex to "none" for all of the children nodes and when i press ok, it still shows the default image for each child node.
Thanks

我不确定，但我相信您可以通过 TreeView 中的每个控件在 [TreeView].Controls... 中执行 foreach... 在那里您可以搜索 [control].GetType() == typeof( [type_of_the_image]），并执行一些逻辑以获取主要图像。
除此之外，您可以通过 jQuery 删除，执行类似于我上面所说的操作。如果您对这些想法感兴趣，我可以帮助您开发。
I'm not sure of it, but I believe that you can pass through every control inside the TreeView doing a foreach in [TreeView].Controls... In there you can search for [control].GetType() == typeof([type_of_the_image]), and do some logic to get just the main ones.
Besides that, you can remove by jQuery, doing something close to what I said above. If these ideas are something that interests you, I can help with the development.
