Databinding XML to a TreeView

[=?Utf-8?B?QnJpYW4gTmljaG9sc29u?=]

Hello -- I'm having problems figuring out how to bind an XML file to a
treeview control. I have the following test XML:

<?xml version="1.0" encoding="utf-8"?>
<instruments>
<instrument name="Name1" type="Type1" path="Path1" />
<instrument name="Name2" type="Type2" path="Path2" />
<instrument name="Name3" type="Type3" path="Path3" />
</instruments>

And I try databinding it to the TreeView with the following:

Dim xmlds As New XmlDataSource()
xmlds.DataFile = Server.MapPath("test.xml")
treeSrc.DataSource = xmlds
treeSrc.DataBind()

The problem is that the items appear in the tree like this:

instruments
instrument
instrument
instrument

But I would instead rather have them appear like this:

Name1 [Type1]
Name2 [Type2]
Name3 [Type3]

I figure I'll have to implement custom data binding, but I can't figure out
how.

Thanks for your help.

Hello Brian,

Please try the XMLDataSource control, assign your XML file to this control.
and then bind your treeview with this XML datasource and then do the
Databinding for each node in the treeview something similar to our control.

<c1c:C1WebBinding DataMember="channels" Text="channels"></c1c:C1WebBinding>
<c1c:C1WebBinding DataMember="channel" TextField="id"></c1c:C1WebBinding>
<c1c:C1WebBinding DataMember="message" ToolTipField="comment"
NavigateUrlField="link" TextField="title"></c1c:C1WebBinding>

Thanks; this helped to an extent. I now have the following:

instruments
Name1
Name2
Name3

Each "instrument" node has both a name and a type value -- is there a way to
get both of these to appear simultaneously in the TextField?
