Using Recurisive i can do this but i don't how to do..
In my website, I have a TreeView that has this structure:
Root
|-Leaf
|-Parent
|--Leaf
|--Leaf
|--Child
|---Leaf
|---Leaf
|--Child
|---Leaf
|---Leaf
Is it possible to make the tree in a "collapsed" state where all the Leaf nodes and ONLY leaf nodes are hidden from view until its parent node is expanded? The ideal solution would be to do this without a postback, but any solution at this time would be helpful. The "collapsed" view would look like this:
Root
|-Parent
|--Child
|--Child
Expanding the Root, Parent or Child nodes should show their Leaf nodes. Collapsing the node should re-hide its leaf nodes, but leave the child nodes visible.
I need to know a way to disable nodes in a tree view when a particular node is checked (the leafs has check boxes), currently I was able to do it but my problem is I have check the check box, then click on the node in order to get it disabled, this not an user friendly at all. I want it to happen when I check the checkbox in the tree node.

I have been trying to delete nodes from a tree view that is being generated from a database. I have the code written and it works, but only on the root Nodes. It will not delete Parents/Childs/Leaf, it will if I delete the root, but I also want to be able to delete parent nodes and such.
Right now i have this code so far
Dim tn As TreeNode = treeView.SelectedNode
treeView.Nodes.Remove(tn)
I know that I can just use treeView.Nodes.Remove(treeView.SelectedNode) but was doing some error checking to see if I could firgue out what was going on. I am using VB6, I am not so worried about the database deleting at the moment. I would prefer not to use the Clear() method as this will remove all the nodes I only want to remove certain ones and keep the rest.
I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?

View 1 RepliesWhen installing an Umbraco site, I changed my umbraco admin url from '/umbraco/' to '/myadminurl/', even before I went through the install process.
Just like it's documented, I changed in the web.config the keys 'umbracoReservedPaths' and 'umbracoPath' to match my new admin url.
Installed and everything is working fine, except for one thing: All the nodes in the trees in all sections aren't showing any thumbnails. There used to be a win folder thumb before each tree node, but now it's just empty, except for the 'packages' node in the developer section, and for the recycle bin thumb.

I am able to bind the first level nodes from the xml but not able to display the child nodes in the xml onto the detailsview on grid.
find my snippet below and help me in correcting the issue. I don't want to use the aspx page to bind the datasource.

I have a treeview and all nodes are check box, when user clicks on a button, how can I get all the checked child nodes belongs to specific parent? I wanna something better...
private TreeNodeCollection GetCheckedNodeForParent (string parentNode)
{
TreeNodeCollection treeNodeCollection=new TreeNodeCollection();
foreach (TreeNode node in tvBaseline.FindNode(parentNode).ChildNodes)
{
if (node.Checked)
treeNodeCollection.Add(node);
}
return treeNodeCollection;
}
I have a TreeView control on a ASP.Net page, and the data will be populate by DataBinding, using XMLDataSource.
<asp:TreeView id="treeview1" runat="server" DataSourceID="xmlDataSource1">
<DataBindings>
<asp:TreeNodeBinding DataMember="All" TextField="#InnerText" />
<asp:TreeNodeBinding DataMember="Categorie" TextField="#InnerText" />
<asp:TreeNodeBinding DataMember="Question" TextField="#InnerText" ValueField="id" />
</DataBindings>
</asp:TreeView>
The XML Data document is as follow:
<All>
<ProjectName>
Project A
<Categorie>
[code]....
It's like something wrong with the TreeNodeBinding. But changing the TextField to example "Value" doesn't work (empty node text).
i don't use XSLT transform file. The Xml will be given directly to the XmlDataSource.
I'm positive that, by now, a lot of people have run into this problem but even with all the forum posts with great answers, I still can't seem to get to the bottom of it. Here are some specs:
Windows Server 2008 Visual Studio 2008 x86 So here's the issue:
I have VS2008 installed on the server listed above. This is our development server and everything is created and tested here. I have created an asp.net application, tested it on the dev. environment and everything works great. When I try to migrate this application up to our Quality Assurance environment (which is Windows Server 2003), I get the error in the subject title.
I've read many things that can be the cause of this and I'm positive that I know 2 ways of fixing it. One is from this post: Simple web site problem on Vista, related to <providerOption>, and the other is making sure 3.5 framework is at least installed on the server in question. There are 2 reasons why I'm unable to use these 2 methods:
The patches from DVD that I'm supposed to install won't let me install them. Upon double clicking I recieve a message saying the "Update is not applicable to your computer" I don't have permission to install 3.5 framework on the QA server even though it's installed on the Dev server. I've also tried changing the target framework of my application to 2.0 however this creates a bunch of errors as some of the code is not compatible and is unable to publish the project.
Perhaps know a reason why I can't install those .msu updates or have a workaround to the 2.0 vs 3.5 issue?
I'm very new to xml so I hope I'm not asking any silly question here. I'm currently working on populating a treeview from an XML file that is not hierarchically structured. In the xml file that I was given the child and parent nodes are defined within the attributes of the item element. How would I be able to utilize the attributes in order for the treeview to populate in the right hierarchical order. (Example Mary Jane should be a child node of Peter Smith). At present all names are under one another.root
<item parent_id="0" id="1"><content><name>Peter Smith</name></content></item>
<item parent_id="1" id="2"><content><name>Mary Jane</name></content></item>
<item parent_id="1" id="7"><content><name>Lucy Lu</name></content></item>
<item parent_id="2" id="3"><content><name>Informatics Team</name></content></item>
<item parent_id="3" id="4"><content><name>Sandy Chu</name></content></item>
<item parent_id="4" id="5"><content><name>John Smith</name></content></item>
<item parent_id="5" id="6"><content><name>Jane Smith</name></content></item>
