vb.net Treeview from XML AfterSelect

Hi,

I have an application I am building in Visual Express which contains a treeview that populates from XML. The XML looks something like this

<Town>
 <Street>
  <House>
    <Name>John's House</Name>
    <Doornumber>1</Doornumber>
    <Owner>John Smith</Owner>
    <HasPet>Yes</HasPet>
    <LikesGardening>No</LikesGardening>
   </House>
  <House>
    <Name>Jane's House</Name>
    <Doornumber>2</Doornumber>
    <Owner>Jane Jones</Owner>
    <HasPet>No</HasPet>
    <LikesGardening>Yes</LikesGardening>
   </House>
  </Street>
</Town>

Open in new window


The Treeview is coded to look like the following

+Town
  +Street
   - John's House
   - Jane's House

i.e. the treeview ends at the <House> node and displays the name of the <Name> node.

I want the AfterSelect sub to display the other leaf nodes in that <House> in various text fields.

At the moment what I am trying to do is translate the fullpath attribute of the selected node into the XML path, but I am sure there must be a better way to do this.

How would you do it?

Thanks

Mike

I would think that you could get the child nodes for the selected node, and do the processing that you need.

Further to TheLearnedOne's comment, AfterSelect event passes you TreeviewEventArgs which you can use to get the list of all child nodes of the selected now

e.Node.Nodes

and loop through to get all the houses. You can determine if the selected node is a street node by checking the e.Node.Level property.
