View 1 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 am used treeview control within updatepanel,updation was no problem but i am unable to control treeview node expand and collapse.
I want to prevent TreeView Node Collapse when i am clicking the node and redirecting to other page.
View 3 RepliesI'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 have a asp.net tree view control and its being data bound to XML returned from the DB.

I want to add a link of my default.aspx to <MainMenu> tag.
I am writing a programming using Tree View. I have created the Tree View object and have added a node for the root called Favorites. I want the user to be able to enter a value in a text box and once clicking on an add folder button, an event fires that takes the text that was entered in the textbox and creates a new node under the root node of favorites.
I am having a problem with my program in that the user is not able to click on the Favorites root note in order to create another node underneath of it. Favorites is simply displaying on the screen, but they cannot click on it to select it. What do I need to add so that the user can select the node to which they want to add a child node to?
how to read selected node and its parent node values for treeview in asp.net in JAVAscript.
View 3 RepliesI am trying to build a tree view and was able to create one.The tree is a multi-level tree(6 child levels). The problem I am facing is that for some node the node text is more than 260 characters and for those nodes the node is not expanding and showing the child nodes. I read in the web that the Max lenght for the node Text is 260 only. I am picking these node text values from database and they can be longer than the 260 mark.

View 1 RepliesI 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 5 RepliesI having an issue with the ASP.NET Treeview control. I create the treeview just fine but the nodes will not expand or collapse. I see there is a javascript error but it is for line 1 character 0 of the webpage, there is nothing at line 1 character 0.
I am using the ASP:Treeview control in conjunction with the Telerik controls, but I'm not sure if that is an issue.
I saw there was a similar question here but the answer is not pertinent to my site. Has anyone run into this issue before? I've tried searching Google and tried a number of proposed solutions but so far none have worked.
I have a TreeView menu populated from a SiteMapDataSource. The TreeView defaults to all nodes expanded, but the normal client side expand/collapse behaviour for the nodes is not working. I get one Javascript error in my Firebug console, being:
TreeView_ToggleNode is not defined
What could be causing this?

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.
how's it possible to expand or collapse only one parent node at time. i am using Xmldatasource.
View 7 RepliesI'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.

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?

This 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!
