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.
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.
we can get a parent & child value by using 'tvCityGroups.SelectedNode.ValuePath' then how can i get the parent & child Text in treeview.

View 1 RepliesI had applied the following code as said by you :
byte[] b = YourByteArrayFromDb;
File.WriteAllBytes(MyFilePath, b);
But I am receiving an exception "Access to the path is denied". How do I solve this using ASP.Net with C#? And is there any format to set the path as string?

then i want to write it on FTP using following code.
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();

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 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 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.

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.

Along those lines i would also like to have all expanded or collapsed mainated after a postback.

View 1 RepliesI have a form where users can store some data for archived documents. All documents are ONLY in PDF format.
There are 2 things I would like to do:
1. there is a "file path" text box on the form. I would like to open a "browse file dialog" box when user clicks the textbox and then the user browses for the file (file is on the users local machine) and selects it. The full file path should be saved to the textbox as string (e.g. "c:archive2010document11122011.pdf"). Also I would like to "limit" the file browser dialog to only show PDF format files...
2. add a code behind command to open the file from the saved path+name (see 1.) in the user's default PDF viewer (Acrobat or Foxit)
