View 3 RepliesOn 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've built a TreeView in ASP.NET 3.5 and it works great, except the expand and collapse images (which are 20px by 20px) do not align properly with the text in the nodes. Below is a screen shot of the applicable tree, with all items selected to allow you to see where the items are lined up. I need the text to be vertically centered (by one means or another) so it lines up with the center of its expand/collapse image.
I've tried numerous tricks to make this happen, including CSS, but can't seem to find the right technique.

I am used treeview control within updatepanel,updation was no problem but i am unable to control treeview node expand and collapse.
I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

View 3 RepliesI am experiencing an issue with the TreeView control when loading new pages. It is databound to web.sitemap, but when loading a new page, it does not select the node of the current page, just resets it to the root. THe new page loads fine, just not preserving the current navigation in the tree view.
View 2 RepliesI 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.
how's it possible to expand or collapse only one parent node at time. i am using Xmldatasource.
View 7 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 a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page.
But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?
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?

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?

What 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
