[Solved] Accessing control data in Razor

[Jonathan]

Right now, I'm trying to write a web page that has two major items: a TreeView and an Upload. The idea is that the TreeView represents a file structure on the hard drive (I got that working fine), and the Upload lets you upload files somewhere into that structure. The way I intend to let the user control where the uploaded files go is to somehow let the Upload know what node in the TreeView is currently selected.

What I'd like to do is pass the value of the currently selected node (which holds the full directory path that that node represents as a string) in as a route value in the Upload's Save() call. The only problem is that I don't know how to access the TreeView's nodes from within the definition of the route values. So basically, what would I put in place of the question marks in this snippet:

@(Html.Telerik().Upload()
    .Name("files")
    .Multiple(true)
    .Async(async => async
        .Save("Save", "File", new { @destinationDirectory = ???????})
        .Remove("Remove", "File")
        .AutoUpload(true)
    )
)

I know that in javascript I can just do

$('#fileViewer').data("tTreeView").getItemValue(e.item);

where "fileViewer" is the name of the TreeView. So I guess another way to look at the question is: what's the razor equivalent of that?

I'm working with all the latest stable versions of ASP.Net, MVC, and Telerik, and I'm working in C#.

Hi Jonathan,

There is no way to access TreeView's nodes from within the definition of the route values.
To pass the selected node you need to declare a handler for the OnUpload event and attach a data object, which contains the path, to the passed event. There is more detailed information on how to achieve this in the documentation. 

Kind regards,

Yeah, I had somebody else explain the difference between client and server side things to me. Thanks anyway!
