Web Forms :: Expand A Particular Node On Treeview
Jun 22, 2010What 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

Web Forms :: TreeView Expand/collapse Images Aren't Aligned With Node Text
Jul 16, 2010I'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.

View 3 RepliesExpand TreeView Node By Clicking Its Text Instead Of "+/-"
Jan 12, 2011I'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.

View 1 RepliesWeb Forms :: How To Highlight Selected Node In Treeview Using Javascript
Jun 30, 2010Im using an asp.net treeview control and i managed to get code from these forums so that when i select a node no postback is done but i can access the selected node in my C# code behind pages by using javascript.
It works fine i can get the selected node by saying:
TreeNode t = TreeView1.SelectedNode;
and then displaying it to a label on an on click event of a button:
Label1.Text = t.Text;
But what i really need is to either display the node selected to a label (or textbox) or when a node is selected it needs to be highlighted so that the end user knows the option chosen is selected.

Treeview Default Expand?
Apr 17, 2012how I can set a default view for a treeview. meaning I have a treeview created and has some data in it. when the page first loads it just shows the treeview. I need to actually display the very first node's data. So i have the treeview, with a parent node and 3 child nodes. I need to dynamically get the the parentnode and then get the first child node and display that data without clicking. I could just hard code the path in, but since this is still in development more nodes will be added and there for the order could change.
