[.net] TreeView Nodes

Should be pretty straight forward. Assuming you have a button created, and a function assigned to when that button is clicked, and the TreeView object is a member of the object the code is in, it should be something like this:



Of course if you wanted it to change to something other than "Hello World!" you could always read the string from a text box or something when the button is clicked.

Basically, the key to working with a tree view is to know the node structure. The nodes are objects of type TreeNode stored in a TreeNodeContainer. myTreeView.Nodes gives you access to that. Because a TreeView supports multiple levels, each TreeNode also has a Nodes collection, so you can do stuff like:

myTreeView.Nodes[0].Nodes[1].Text = "Hello World!"

Which would take the first node in the top branch, and then go to the 2nd node under that branch and change the text.

Well, your kinda close. I want the user to be able to click the button (once the node is selected) and be able to type in what they want it to be called. From my programming I already have a name set everytime the user clicks the "New Node" button, if you click new node, it makes a child node to the one selected THAT IS ALREADY NAMED "NAME". So, what I need is once someone clicks that rename node button the user will be able to change the name of the node selected (remember, the default name for a newly created node is "Name" according to what I have programmed). Get it?

You mean like how in Explorer's tree view you can click a node, and then an edit box will show up on the node that'll let you type in the new name?

Take a look at TreeNode.BeginEdit. You also need to set TreeView.LabelEdit to true.

Your exactly right,

Thanks mutex! I'll look into it right away.
