C# XML ListBox

[EinToR]

I'm trying to make a series of listboxes that filter the next listbox.

Ex.:
Listbox01: Toyota, Hundai
Listbox02 (Toyota selected): Supra, Corola
Listbox03: (Supra selected): Red, Black

The DataSource is an XML file simnilar to this:

<items>
  <item name="Toyota">
    <item name="Supra">
      <item name="Red"></item>
      <item name="Black"></item>
    </item>
    <item name="Corola">
      <item name="Red"></item>
      <item name="Green"></item>
    </item>
  </item>
  <item name="Hundai">
    <item name="Elantra">
      <item name="Black"></item>
      <item name="Blue"></item>
    </item>
  </item>
</items>

I know how to create the listboxes but can't figure out how to query the XML to get what I want. It has to be done in C# 2.0...

I would make an object which holds a collection of models and also a collection of colours, or if colours are model specific i would put the colour collection in inside te model object.

thus fill the object using the parent/child relationship of the XML. you could make an array of these objects and insert that a as the datasource for your first text box, then fill the other text boxes with the data in the object, not directly from the XML file.

good luck

I'm not sure if you are developing ASP.NET or a desktop application. If you are developing an ASP.NET application there is a CascadingDropDo wn control that CodePlex has made freely available to developers. It's not ListBoxes but I think it would accomplish what you would like to do.
