Image associated with a TreeView Node

Hi,

I am a little confused about associating an image w/ the VB.NET TreeView
Control. My specific requirement is that I want to associate an image w/ some
specific nodes in the TreeView only.

I coded a test project with a form with a TreeView and an ImageList control.

///
Me.TreeView = Me.ImageList
\\\

'The above statement associates the image at the 0th index of the ImageList
w/ all the nodes of the treeview.

The only way I was able to turn off an image for a particular node is by
saying
\\\
Node.ImageIndex = <Some invalid index of the imagelist>
///

If the treeview has a lot of nodes, this would be a painful thing to do.

Have I misunderstood something?? How can I associate an Image w/ say just
1node in the treeview?

Looking forward to your responses!

TIA

i have a very odd behaving treeview. i use image list with a bunch of icons and as nodes get added to a tree i assign image index to each node. everething works fine, no problems there. now, when i click on any node it's icon changes to icon with index 0 in image list, and as i move to another node the original image comes back. i have no events handling in code, so this is a mistery.

Hello, I knew how to use the treeview under VB6. After migrating to .NET, well, I'm lost. I try to add a new node, either to the same level or as a child to a selected node in the treeview. However, either it only add it to the root level or it only add it on level below, doesn't matter what I select. And in some case, I just get an exception.

I'm building a treeview from an xml file. The node values point to various paths, some of which are network paths. Next to every node I'd like to display an "offline" image (if that the path is not accessible). I'd like to do this either before or after the user selects that particular node. How do I check for a path's status? Also I've played around with the AfterSelect event combined with

Hi, I have a treeview which contains nodes of a class (classA) derived from treenode. These classA nodes may contain nodes of a class (ClassB) derived from classA. The form load populates a imagelist and calls a subroutine that assigns an image to each node depending on its type. If I expand a classA node, all is well. ie. I see the classA image on the classA node and the classB image on the exposed classB node (which is always

Hello, In a MDI application, I want a child form which contains a treeview with a associated form for each node. If I create a child form, I only can put controls.

Hi All, I have a form that displays hierarchical categories in a treeview. Ok so far so good. What I was to do is have users be able to select a node in the treeview as part of filling out the form. I only want to allow single selection, so using checkboxes is out of the question. It works as is, but it makes the form very cumbersome if every time that a user selects a node, the whole page has to reload. Is there a way to have a node...

Hi, How can I make root node of a TreeView control to have different expanded and collapsed images from the rest of the tree? If I use "ExpandImageUrl" and "CollapseImageUrl" it applies to all nodes including the root. And if I use "RootNodeStyle-ImageUrl" the image stays the same even if expand or collapse the root node. Appreciate your help. Thanks, Harish.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
