Question : WPF, VB.net, generating a multi column listbox from list (of type Structure)

Hi Experts,

I am new to WPF. I want to display a MULTI COLUMN listbox or listview or datagrid/table of some sort. The data should come from a generic list (of type Structure). As a stubborn programmer, I prefer to apply my ASP.net patterns to this new WPF paradigm, if at all possible.

Here is how I would generate the data in ASP.net:

response.write ("<table>")
myList = myEmp.getStructEmployeeList("SEN", "Active")
For Each item In myList
response.write("<tr>")
response.write("<td>" & item.LastName & "</td>")
response.write("<td>" & item.FirstName& "</td>")
response.write("<td>" & item.City & "</td>")
response.write("<td>" & item.State & "</td>")
response.write("<tr>")
Next
response.write ("</table>")

'The method get.StructEmployeeList returns EmployeeList - List(Of Employees_Structure)

Public Structure Employees_Structure
Public EmployeeNumber As Integer
Public LastName As String
Public FirstName As String
Public Initial As Char
Public HomeAddress As String
Public HomeAddress2 As String
Public City As String
Public State As String
Public ZipCode As String
etc...
End Structure

I was able to use this for-each-loop pattern and generate a SINGLE column listbox in WPF.

myList = myEmp.getStructEmployeeList("SEN", "Active")
For Each item In myList
ListBox1.Items.Add(item.LastName & ", " & item.FirstName & " (" & item.EmployeeNumber & ")")
Next

But I can't seem to generate anything with multiple columns in WPF.

Thanks,
