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 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:
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 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!
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 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 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.
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.
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.
