displaying tree structure 1

[ArmenD]

how do i create & render a tree structure of categories in asp.net using vb?

i want to render the following on a web page...

Animal->Dog
->Cat
->meow
->Horse
Tree -> Pine
-> Redwood
-> Some other tree
->Big
->not too big

i am hoping there is some kind of data structure that already does this. src code or links to is appreciated.

i am trying to find an example that shows how i can display a treeview control horizontally...

example
a->b->c

how is this done? I just want the look of a linked list?

Could you just use HyperLink controls? They could just be created dynamically when needed to make the "look of a linked list" display that you are looking for.

can u elaborate on how it can be made dynamically without refreshing the page?

I'm not sure I understand why you need to do it without refreshing the page. Surely by the Page Load you will know what links need to be displayed.

Although I mentioned hyperlink controls, for a simpler example I have just used a literal control and set the text property by using anchor tags. See if this is the type of solution you are looking for:

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here

        Dim lit As New LiteralControl
        For i As Integer = 1 To 5
            lit.Text &= "<a href=""" & i & ".aspx""> " & i & "</a> > "
        Next
        Panel1.Controls.Add(lit)

    End Sub
