Passing radComboBoxContext to client

[Vladimir]

Hello.
I have a question if there is some way to pass some information from server WCF to client combobox object. for example using RadComboBoxData.Context.

The situation is^ combobox populated with two queries in single WCF method.
I want to know how match items werel loaded by each query, to use this information in "show more" to organize some kind of paging.

var result = new RadComboBoxData();
result.Context["users"] = context.ContainsKey("users") ? Convert.ToInt32(context["users"]) : 0 + userList.Count();
result.Context["contacts"] = context.ContainsKey("contacts") ? Convert.ToInt32(context["contacts"]) : 0 + userList.Count();
return result;

But there is no "users" and "contacts" keys in second request, only standart text and numberOfItems.
Is there anything I've missed?

Thanks

Hi Vladimir,

Did you review the following help article?
You may subscribe to the onClientRequesting event and access the RadComboBoxData.Context trough the arguments:

function onClientRequesting(sender, e)
    {
        var context = e.get_context();
         .............
    }

Kind regards,

Hi Vladimir,

Actually it is not possible. Did you review our paging example for RadComboBox Load On Demand:
