I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure). Initially, the node 1 is parent and its child nodes are 2 and 3. The node 3 has child nodes 4 and 5. At run time the pressure changes. Now, node 3 is parent and its child nodes are 1, 4 and 5. The node 1 has child node 2.

View 3 Replieshave a treeview with 13 different categories. Under each category are many sub-categories.At the minute the icons used to represent the categories are the plus/minus signs.I would like to use an Imagelist to change the icons to a closed folder icon when closed and an open folder icon when opened.

How can I determine programmatically, whether one of these events/changes was occur?

I'm a newbie to VB 2008 Express. I have a treeview to which I'm trying to add icons. I've added the icons to the treeview images collection, and I've put an imagelist on the form and added the icons to the listview images collection. I can't seem to work out the syntax required to show the icons.
Code:
Me.TreeView1.Nodes(0).Nodes.Add(driveName(i) & volumeLabel(i), _
driveName(i) & " " & volumeLabel(i) & formatSize(freeSpace(i)) _
, ??? )

View 1 RepliesI have a treeview, and lets say in the treeview I have the nodes "Textbox1", "Textbox2", and "Textbox3". Also on the form I have 3 textboxes. What I want it to do is when I click "Textbox1" in the tree, to select all text and bring focus to the first textbox. So on the AfterSelect event of the treeview, I find out what node Im on, and what textbox to go to, then I say Textbox1.Focus() : Textbox1.SelectAll().When I use the keyboard and navigate to that node, it works. It jumps the focus off of the treeview and to that textbox, selecting all it's text. Works fine.But when I click on it with my mouse, it doesn't. It does select the text, bring focus to the textbox, but immediately brings focus right back to the treeview. (you have to look really close to see it) I'm thinking there's some mouse event that is bringing the focus back to the treeview, but not sure what.

View 10 RepliesI have a treeview. The root nodes have images set at 30x30 - is there a way to add child nodes with NO image or a smaller image? I can do a blank image, but each child is spaced far apart! I would like the child nodes to be like there is no image... tight and close to each other.
View 13 RepliesI have a TreeView with several nodes that have child nodes. Whenever I create a child node, it sets the image to a seemingly random icon in my ImageList. There are a couple of properties for the TreeView that have this icon, but nothing happens when I change it to a different one. And besides, it won't let me set those properties to "None."
I tried look at the properties of the child nodes, but everything is set to none and nothing changes. Does anyone have any ideas? In the photo below, you'll see the Internet Explorer node and its child nodes that have the Chrome icon. I need the child nodes to be blank.

How do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
