AJAX :: When Expand Another Node, The Previous Expanded Node Collapses?
Oct 19, 2010
I created a sitemap with a treeview navigation in my aspx site. I am hoping someone can show me the code to put in a Masterpage so that when I expand a child node, all other nodes collapse, and when I expand another node, the previous expanded node collapses.
I have an example here of what I am trying to accomplish:

I am using asp.net with VB.
I have been scouring the internet looking for a solution, but so far haven't found anything that works.
I created a sitemap with a treeview navigation in my aspx site. I am hoping someone can show me the code to put in a Masterpage so that when I expand a child node, all other nodes collapse, and when I expand another node, the previous expanded node collapses.
I have an example here of what I am trying to accomplish:
I'm populating a treeview dynamically. On OnTreeNodePopulate I call a sub and populate the Parent nodes. I do not want to populate the child nodes at this time. Upto this point it works fine.
Now I would like the user to click the parent node and then populate the child node. I tried to use TreeNodeExpanded, but that is called for each parent node, so that didn't work.
MainMenu is the Parent node and Tracker, Reports ... are subodes. I want that if I click the node Tracker the all it's parent nodes(NBD, EOI, Proposal, Project, Sub Contract) should expand the remaining treevew remain same.
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've been using hardcoded hyperlinks for my web app navigation, but the app has grown since and managing it is becoming a real pain. I've decided to replace what I have with the TreeView control, however I want to make several changes to the way it looks. Is there any property that needs to be set, that would allow user to expand the TreeView node by clicking its text instead of +/- ? I've already set ShowExpandColapse to 'false'. I want my final result to end up as something similar to the TreeView on the left of the MSDN site.
I have a second level node that goes onto two lines. The first line indents 15px as is set by the class for node level 2. The seond line kicks back to the same level as 1st level nodes. Here's what I mean:
i want to create one treeview dynamically which will have child node and sub child node.for this i am getting my treeview value from the table with below column:Id,Name,Parent,IsActivewhere main parent nodes parent id will be 0 and then all other records parent id would be related id. the table structure would look
I have four collapsiblepanelextendrs on my page. Now i want that whenever, i click on one extender to expand others panels in expanded state should be collapsed at same time. How can i achieve this in C#
I have a treeview, the TreeNode's NavigateUrl have a javascript function, after i click the "Item 1", it shows a message box ("1"), but it does not expand the child node, what can i do?
I have a tree-view which doesn't have any events and AutoPostBack property is also false. But whenever the treeview node is selected,its taking a lot of time...The tree view is placed inside update panel...I have an update progress and selection of any node shows the progress for atleast 5-6 seconds.
I have a treeview and a button inside a panel. On a click of button 'btnView' i want to show the panel. So i decided to use the ajax modal popup. Every thing is fine but mu popup closes on selecting a node in the treeview. Actually i want to close the popup on click of button 'btnOK'. Here is my page markup
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?
Ok so the code below works to inject a new node in to my XML document, however I can't figure out how to pass properties in to the node. So for instance if I wanted the date in the node I would want something like this
<submission date="2/29/10">Text Inside The Node</submission> protected void submitButton_Click(object sender, EventArgs e) { XmlDocument doc = new XmlDocument(); XPathNavigator xpath; //used to navigate tru the XML file
