Web Forms :: Treeview: Click Node Text To Expand/collapse?

Mar 10, 2011

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# ?

Web Forms :: TreeView Expand/collapse Images Aren't Aligned With Node Text

Jul 16, 2010

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.

Web Forms :: Expand And Collapse Treeview Control?

Feb 11, 2010

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.

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!

Expand TreeView Node By Clicking Its Text Instead Of "+/-"

Jan 12, 2011

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.

Web Forms :: Expand A Particular Node On Treeview

Jun 22, 2010

What I am acheiving is a simple treeview which will have a tree structure

dir1
-- xx
dir2
Simple stuff !. Here is the code

TreeNode tree1 = new TreeNode("dir1", "", "", "dir1", "");
tree.Nodes.Add(tree1);
TreeNode node = new TreeNode("xx", "xx");
tree1.ChildNodes.Add(node);
TreeNode tree2 = new TreeNode("dir2", "", "", "dir2", "");
tree.Nodes.Add(tree2);

Now I want to do is collapse all the tree and find a particular node e.g dir1xx
I have put the code

tree.CollapseAll();
tree.FindNode("dir1").Select(); <-- falls over
tree.FindNode("dir1").Expand();
tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();

but it falls over on the 2nd line with object not set

When Expand And Collapse Nodes In The Treeview, The SurroundingWrapper Div Resizes?

Oct 18, 2010

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?

Web Forms :: TreeView - User Isn't Able To Click On Favorites Root Note In Order To Create Another Node Underneath Of It

Jul 14, 2010

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?
