How can I get the id of an expanded node of a treepanel in the ASP side?

[Elfayer]

Hi,

I have that Model:

Ext.define('EXC.model.TreeStore', {
    extend: 'Ext.data.Model',
    fields: [
    { name: 'id', type: 'int' },
    { name: 'name', type: 'string' },
    { name: 'leaf', type: 'bool' }
    ],
    proxy: {
        type: 'ajax',
        actionMethods: {
            read: 'POST'
        },
        api: {
            read: '/File/GetFile/'
        }
    }
}); 

And I would like to know how can I get the id of an expended node of my treeStore.
I tried :

            long id = Convert.ToInt64(Request.Form["id"]); 

But that always return 0.

Node id is sent with the param named 'node' not 'id'.

Request.Form["node"] 

return NaN for the root node.

node param sent in GET

[vietits]

That's because your root node does not have an id.

Is there no way to send it in POST?
Because the problem is that if I try in GET, I have an error that tells:

This request has been blocked because of sensitive information wich could be transmit to other Web sites when using a GET request. To allow GET requests, set JsonRequestBehavior to the AllowGet value.

With your code, request params for reading request are sent by POST not GET.

sorry, 4.1.x send node param in POST
