I am used treeview control within updatepanel,updation was no problem but i am unable to control treeview node expand and collapse.
I am trying to use a treeview control in my application. From the begining I had one parentnode and several childnodes for each parentnode. I wanted to be able to close an opened node when I click on a new one and I maneged that with OnTreeNodeExpanded method.
My problem is that I now need to expand my treeview so it will look something like this:
[code]....
What I want now is:
1. to be able to close an opened parentNode if i click on some other parentNode,
2. if i click on childNode i want to expand it so I can see grandchild,
3. if i click on another childNode for the same parentNode I want that the allready expanded childNode collapses and that the childNode I clicked on to expand.
I want to add, edit(update) and delete a node from a treeview. These all opeartion must be performed on the treeview itself.
I am using VS2010 with framework 3.5, in asp.net c# language.
My database is Mysql.
I have a sitemap with about 50 nodes. I want to expand the nodes for specific links directly related to the node group to which the current page belongs. Currently, when I navigate to a page, all nodes are expanded by default. Is there a properly I can use to control this behavior?
View 1 RepliesI am using Tree view to display Categories & SubCategories under it. It's working fine. to create a Tree View I had used,
http://aspalliance.com/732.
Problem is that I want my TreeView to be expanded. How can one do that? Moreover, From another page when I click a Product, I want that in treeView that Category(under which Product falls), should be expanded & node(ie selected Product) should be highlighted.
how I can set a default view for a treeview. meaning I have a treeview created and has some data in it. when the page first loads it just shows the treeview. I need to actually display the very first node's data. So i have the treeview, with a parent node and 3 child nodes. I need to dynamically get the the parentnode and then get the first child node and display that data without clicking. I could just hard code the path in, but since this is still in development more nodes will be added and there for the order could change.
View 2 RepliesWhat I am acheiving is a simple treeview which will have a tree structure
dir1
-- xx
dir2
Simple stuff !. Here is the code
TreeNode tree1 = new TreeNode("dir1", "", "", "dir1", "");
tree.Nodes.Add(tree1);
TreeNode node = new TreeNode("xx", "xx");
tree1.ChildNodes.Add(node);
TreeNode tree2 = new TreeNode("dir2", "", "", "dir2", "");
tree.Nodes.Add(tree2);
Now I want to do is collapse all the tree and find a particular node e.g dir1xx
I have put the code
tree.CollapseAll();
tree.FindNode("dir1").Select(); <-- falls over
tree.FindNode("dir1").Expand();
tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();
but it falls over on the 2nd line with object not set
in my asp.net treeview if i click one parent node then it should be extended if i click again on that node it should be collapsed in treeview...
is any javascript availabe for this? or any code in selected node changed?

I am using a SiteMap data source boudn to a navigation control. I would like to also put this in the footer (sort of like the bottom of Yahoo! pages) where all items are expanded and static.
So my major heading would be across the top (horizontal) and the sub items would be indented vertically below and always expanded. Is there a way to do this? Check out the bottom of the BlackBerry DEVCON 2010 site for an example:[URL]
I've got a Treeview inside an Updatepanel, currently I'm developing directly on a dev server with a remote connection to it. I've set the CollapseImageUrl and ExpandImageUrl properties and when I view it on the dev servers' browser it renders fine.
It produces:

I have a TreeView that has a border around the expand/contract area (where the plus or minus icons live). I'm looking for how to turn it off. I'm guessing that this is begin inherited from some CSS somewhere, but it fails even if I put it inside a border-free div, like this:
[Code]....
I was hoping to find a <ExpandContractAreaStyle> construct, like <NodeStyle>, but I must be missing something.
The following is a version of some code I'm having trouble running in IE version 6. It seems to work fine in IE 7, IE 8, FireFox, and Google Chrome. But in IE 6, when I expand and collapse nodes in the treeview, the SurroundingWrapper div resizes, but the message at the bottom stays glued in place (I'd prefer it stayed glued to the bottom of the div SurroundingWrapper). Can someone please tell my why this code falls apart in IE 6?

I'm new to the Ajax Control Tool Kits and I was trying to use the accordion control which is cool according to
its sample.
I followed this video tutorials, however after I created the simple demo, the accordion control doesn't collapse or expand. It just didn't respond to my clicks.
Following is my code and I've trimmed is as simple as possible.

On a treeview, you can collapse/expand the nodes by clicking the +/- icon.
I would like to know how I can also click the node text to achieve the same results.
I want to be able to click the node text to expand/collapse the node.
How can I do this in ASP.NET/C# ?
I have Already used many treeview in my web page, when any user try to expand them the web page view will become not so good because every treeview has expanded.how can I close every treeview when any user expand one of them?
View 12 RepliesThis is so frustrating...that such a simple feature should not be included in the design of this control. I am using the cssfriendly adapters and the rendered code is shown below.
I thought I might be able to use the adapter's treeview JS function ExpandCollapse__AspNetTreeView(this) since this is what is called when I click on the node that causes it to expand/contract. But that did not work.
I have seen other code posted but it seemed to imply the treeview was a table not a ul.
Does anyone know how to simply expand or collapse all nodes from a link button without doing the postback. Of course the postback works but what a waste to have to postback to do such a simple action.
Why doesn' t MS consider the users and developers when creating these controls and tools? Stupid!

I have been having an issue when expanding a treeview, it looks fine when I load it, but when I click on a parent node it does expand, but also puts like 2 other parent nodes undernearth it. I am thinking it's because the treeview is saying that the parent nodes that have children have an index of 0, while everything else as there own index.
