Simple example:
string someText = yourTextBox.Text;
TreeNode aNode = new TreeNode();
aNode.Name = "some name here";
aNode.Text = someText;
yourTreeCtrl.Nodes.Add(aNode);

Google "reading text file in C#", this is basic IO. It's a text file, look at the StreamReader, (or even the XmlTextReader if you really need it, though it doesn't sound like you do).

Tut tut. It's always urgent. Saying this is just plain rude and inconsiderate. Why do you think your requirements are any more urgent than all of the other posters? This is a volunteer only forum, so you have to be patient and wait for the relevant volunteers to get round to answering your questions. Pestering people and posting crap like this makes it less likely that you will get help. We get very annoyed at people with attitudes like this.

Do you want to display XML file contents to a rich text box ?

AFAIK, you need to handle the event which fires when a node is deleted, then find the same node in the XML file and delete it. Then save the file. You can use XMLDocument class for this.

I replied to your other thread, but you should be using the XMLDataSource and it's Save method to save the XML. I beleive you should just be able to add nodes by creating a new node entry.
// Create the new node.
TreeNode newNode = new TreeNode();
newNode.Text = row["CategoryName"].ToString();
newNode.Value = row["CategoryID"].ToString();
// Set the PopulateOnDemand property to true so that the child nodes can be
// dynamically populated.
newNode.PopulateOnDemand = true;
// Set additional properties for the node.
newNode.SelectAction = TreeNodeSelectAction.Expand;
// Add the new node to the ChildNodes collection of the parent node.
node.ChildNodes.Add(newNode);
I did a quick look and it appears you should be using the XmlDataSource for the TreeView's Datasource. There is a Save method on the XmlDataSource, so I would start there and see what you can figure out. http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.xmldatasource.save(VS.80).aspx[^]
Have you come up with any good ideas?
