Client-side binding, how to get raw AJAX response object?

[Jason]

I'm using client-side binding to a WebMethod, and I need to intercept the AJAX response object. I can get the row objects that are children of the response in the OnRowDataBound through args.get_dataItem(); how to do I get the return object from the WebMethod (either before or after the grid is bound at client-side)?

Hi Jason,

You could take a look at the OnDataBinding and OnDataSourceResolved client events and its argument properties described in the help articles below. We wrap the AJAX response object and provide related data in these events. We do not directly expose the raw AJAX response object.

• OnDataBinding
• OnDataSourceResolved

So if my webmethod returns the following object, I can only get at the "Data" property, and I have no way of accessing the "IsError" or "ErrorMessage" properties?

public class FlattenedReportResult<T>
{
   public int Count { get; set; }
   public List<T> Data { get; set; }
   public bool IsError { get; set; }
   public string ErrorMessage { get; set; }
}

Hello Jason,

You could achieve your scenario but it is not trivial implementation. The idea is to manually bind the grid by creating your own ajax request using jQuery ajax function. I have provided a demo for the client-side binding of RadGrid and an article covering ajax usage.

• Grid / Programmatic Binding
• jQuery.ajax()
