GridView for MVC- How to get row values on the client side without callbacks

Hi,

I have an MVCxGridView.

I need to get specific cell data from the grid using ASPxClientGridView. I add the MVCxGridView to the page using the following;

JavaScript
settings.CustomJSProperties = (s, e) =>  
{  
    MVCxGridView g = s as MVCxGridView;  

    Dictionary<int, object> dict = new Dictionary<int, object>();  
    int startIndex = g.PageIndex * g.SettingsPager.PageSize;  
    int endIndex = startIndex + g.SettingsPager.PageSize;  
    for (int i = startIndex; i < endIndex; i++)  
    {  
        dict[i] = g.GetRowValues(i, "shippingnumber");  
    }  
    e.Properties.Add("shipmentData" + ViewBag.Count, dict);  
};  

Now I have a seperate button which calls a client side event and does some ajax work. I want to get hold of these shipments numbers.

Can someone please tell me how to do this? So far I have;

C#
var shipmentGridView = ASPxClientGridView.Cast('@shipmentGridViewId');  

however I cant see from the documentation hot to then access the vars other than using a callback which I would rather aovid please.
