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'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.
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 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 RepliesThe 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?

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# ?
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!

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 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.

I added it and when the user clicks on the panel(working as header) then the collapsing/expanding of another panel(working for displaying the content) works great.All of it happens in the client side;i.e;no need of server side code.But now i want to change it a bit.All i want to do is when the mouse curser moves in/out of the panel(which is the header) then the panel(working for displaying the content) should automatically expand/collapse respectively.

View 2 RepliesI am creating an ASP.NET web Appivation in which I have added many rows in the table.
When I run the application the table is not displayed, only the rows are displayed.
My question is I want to Expand and collapse the rows since they are large in no.
I have a jQuery accordion I have been messing with... everything works how I need it except one thing.
I cannot figure out how to add a collapse and expand button to work.

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.
When I click on the panel's CollapseControl (in my case its pnlTeleReceipt) the panel itself drops down hiding all the controls associated with that panel. However, I expected the panel to be fixed at its place and the controls were supposed to expand and collapse on click of CollapseControl and which is not happening. I've posted the Code below.

Here Am Using Table and grid views For Registration.
Am get Collapse and Expand with Table But There No Data Displayed in Grid view (Means it not Showing asp Controls Like Grid view etc).
May i use the collapse and expand feature (like tree menu) at Report iam using the Report viewer Control for displaying the Report on my Asp.net Page .
I have number records and each record have detail as i clicked or expand the record then details will be shown is it possible with report viewer control as.
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.
View 2 Replieshow to expand and collaps the tree view nodes in asp.net
View 4 RepliesI have a Radtreeview that sits inside a RadGrid. For some reason the expand/collapse buttons of the Treeview are not working. I can expand the Treeview initially, however the NodeExpand event never fires.(a postback does occur to the server, and I have several buttons on the treeview node that work.) Once the node has been expanded, the collapse button doesn't work, and clicking on it does nothing.(no postback to server). I have the ExpandMode set to ServerSide. However, if I change the Expandmode to Clientside it works properly.
I really need the control to work with ExpandMode set to serverside, to reduce the loading for large Tree's.
Im not sure if this matters. But I am adding the Events to the RadTreeview when the event RadGrid_ItemDataBound is fired.I am noticing one strange behavior, that I cannot explain either, if I do not attach an event to NodeExpand It fails to open or close. Also the NodeDataBound event fires successfully and the data is loading fine into the tree.
RadTreeView tree = (RadTreeView)e.Item.FindControl("RadTreeView1");
tree.NodeDataBound += new RadTreeViewEventHandler(RadTreeView1_NodeDataBound);
tree.NodeExpand += new RadTreeViewEventHandler(RadTreeView1_NodeExpand);
tree.NodeCollapse += new RadTreeViewEventHandler(tree_NodeCollapse);

how to have a expand/collapse ALL function on top of individual rows?
I have added 4 CollapsiblePanel programmatically and it is working with IE7 and IE8 but it is not working with IE6 its behaving flashing while expand and collapse and on mouse move to the panel.
View 1 RepliesI 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?
This is one of them.
