Web Forms :: Treeview Expand/collapse All Nodes Client Side?
Mar 26, 2010
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!
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 Jquery. My page looks something like this:
[Code]....
I got it to work using AJAX Control Toolkit, but I find it a bit cumbersome and rather slow. I want to use JQuery for this one.
What I want to do is when the user clicks on <img>Expand/Collapse</img>, divChild will expand/collapse and that row of the GridView will also expand/collapse according to the size of its content.
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'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 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.
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.
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?
I want to populate the search results in grid. The results should be grouped based on condition. I mean if i am searching for name called Osama laden, all the names containing Osama be grouped(+) and Laden as well. I should get the count side to the (+) button. When i click on + button the results should expand and when i click on(-) the results should collapse.
I'm using Treeview control with asp.net 2.0. I would like to know how to get the client side events working. I don't want a post back for every little thing i do with the Treeview. Particularly i want to catch the node click event on the client side using java script, i want to enable/disable buttons based on the selected node. Is this possible? i tried some examples available on net but doesn't seem to be working.
I am looking for a expand/collapse script for a grid view. But after searching around, seems like all sample code are for datagrid instead of grid view. And because there are differences between properties of gridview and datagrid, I can just implement it. Does anyone has any reference for grid view?
I am using .Net Framework 2.0 as its a old application with a datagrid in a page. I want to expand each row when clicked to create a new row to display a page in the newly created row.

Instead when I show here orderdetail.aspx in a different page. I want to show it when any row is expanded based on ordernumber.
I have a updatepanel and div within it. I want to collapse and expand the panel/div on image button click. I tried 3 options
1. Collapsible panel: This is not smooth it closes and opens in intervals bit by bit
2. Accordian: I tried using it in a simple example which worked fine but it didnt work in the project. In the div there are many nested divs and updatepanels. is this a reason that it didnt work in my project?
3. Giving a image button and writing code in cs file on button clickevent to display:none/block the div.
Option 3 worked, but on click of the image button, the button shifts or the background panel shifts the position, hence the panel and image button are not inline(not in the same position as before)
Also, since we are using ASP.NET 3.5 and Ajax, option 1 or 2 looks good but they are not working as expected.
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.
