I have a treeView as the main navigation of the website.
Whenever user selects item im treemenu then POSTBACK is accored, and the treeview reset its state.
How can I force the treeview to remmember the selected item on postback and select a different background so user will know on which item he view?
i am using asp:menu for showing the menus in masterpage. If i click the menu item 1, the corresponding page is loading in the content page. I need that the selected Menu item should be highlighted by some color.

How do I get the value of a treeview's selected node and it's children's values?
TextBox1.Text = TreeView1.SelectedNode.Text; doesn't do it.
I have a TreeView, breadcrumb, and Web.sitemap.
I was given some code a while ago which hid certain nodes from the TreeView but allowed them to appear in the breadcrumb.
Here it is:

I later needed do the same thing but, by now, was using C# instead of VB.
I've tried to translate the VB into C# but the code doesn't work. It doesn't report any design time or run time errors; it just doesn't work (the nodes ARE visible in the TreeView.
Here's the C#:

I'm dynamically generating a tree view on the folder structure on client machine:
C:
-- Folder 1
-- Folder 2
D:
-- Folder 1
--- Folder 11
--- Folder 12
-- Folder 2
etc...
When the user expands and select - say folder 12, I want to get the path as D:/Folder1/Folder12 in to a string
then when the user changes the selection to D:/Folder1 i want to get that path in the string.
I have a treeview loaded with nodes. When I click on a node that is set to .Selected, I want a frame to load with that node's objects. Instead, it appears that the TreeView is posting back and causing the node that was clicked to be lost. For example,setting the below function to OnSelectedNodeChanged causes a NullReferenceException.
Protected Function LoadObject(ByVal sender As Object, ByVal e As EventArgs)
Dim node As TreeNode = tv1.SelectedNode
Response.Write(node.Text.ToString())
I have a treeview and a button.
OnPostBack I wish to know what are the selected categories. also, I need to give a spiciel ID number for each checkbox when data is binding.
Im 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.
i ve used the following code to avoid postback and selected node style for treeview by using this im able to avoid postback but im not able to set selected node style.

On the left hand side I have a tree navigation . It is populated from a XML file with . What I want to achive is when a querystring of the value of the XML file is matched , the tree node sets a setfocus or highlights on a particular node from the querystring passed through. I cant find a method which mimmicks findtreenode with value x and sets a selected .
e.g treenode is filled
home
|
folder 1
| -- item 1
| -- item 2
|
folder 2
| -- item 3
| -- item 4
when a querystring of SC=Item 1 is passed , it should search against the tree and open the folder branch and select item Item 1
I can use a for next loop and loop through each node but it will get slower as more nodes are added.
I don't want to use Sessions to handle each click event inside treeview selected node changed.Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.

View 1 RepliesI am trying to maintain the state of a TreeView on postback. I have a simple method to save the state of the tree on postback but it does not seem to capture the Expanded and the Selected state. Also, i have another method to restore the tree state after a postback. When a user selects an item in the TreeView i would like to have this item highlighted/selected. Along those lines i would also like to have all expanded or collapsed mainated after a postback.

View 2 RepliesI have a user control is shown through a SimpleModal popup (JQuery), this user control gets some data from database and displays them (the details of a record).
The problem is that this user control makes a round-trip to gets the data every PostBack for the parent page even it's hidden.
I wonder if I could make it gets its data only if the popup is appeared.
I tried to put it inside a Panel with false for Visible property and change it to true when I open the popup, but it stil call Page_Load which gets the data from database!
I have an ASP .Net TreeView control that I am dynamically adding tree nodes to from my codebehind on Page_PreRender. The TreeView is populated nicely and the appropriate checkboxes are where they are expected to be. For each of these nodes the SelectAction=TreeNodeSelectAction.None. However, when accessing the TreeView CheckedNodes() collection in my codebehind after selecting a few nodes (checkboxes are selected) and clicking a submit button to post back to the server in the button click event, my CheckedNodes.count() = 0. I can not figure out why my CheckedNodes collection in the codebehind does not contain the nodes that I have checked from the GUI.

I am using a treeview control. I am buliding the tree dynamically. sometimes the tree becomes larger and the down scroll bar is need to see the entire tree. user can select a node from the tree. if one node is selected ,i change the color of the node from server side.
my problem is that if a user selected a node which is bottom in the tree(means, the user used the down scrollbar to see that node), after postback it shows the top of the tree.to see the selected node the user need to use the down scroll bar.
I need to show the selected node after postback. How can I do this?
I am using c# and asp.net
How can I get selected node text and value of asp.net treeview via jQuery?
