I am using the TreeView control for navigation for download files. The files are contained in a SQLServer DB. Some of the tree nodes will initiate a download and others are just for navigation to a specific download file so the property RaisesServerEvent = True is set only on nodes that can trigger a download. I have populated the ItemID with a ID that will be used in a SQL statement to select the download file.

I am using a vb code behind file, but can't seem to figure out how to call the node itemclick event on the aspx page and what vb code to use to handle the click event. I don't need help with the SQL, just a simple example of what I use in the aspx page and the vb code to handle the node itemclick event to do something like change the text of a label would get me going.

Probably pretty simple stuff, but I am pretty green on web based programming. I am using MS Expression Web as the development environment.

Thanks

OK, I am not using VS but Expresseion Web, but I think I have figured out the RaisesServerEvent. What was confusing was that if for example, I create a asp button on a aspx page I have to use something like OnClick="btnID". Since the download files are actually in a DB, then I won't be using a url to get the file, but rather SQL, which I know how to do. The node itemid is a column in my DB so by using it in a SELECT stmt I can get the file for the clicked node.

Now what is the vb to get the itemid for the node that is clicked and show that id as label text for a lable on the page?

Thanks

Ok it must be something simple but so far no joy. When I click a tree node the label text doesn't change.

Here is what I have on the aspx page for the tree and the label:

<eo:TreeView ID="TreeView1" runat="server" ControlSkinID="None" Height="400px" Width="230px" RaisesServerEvent="True">
