Grid Error Handler not being triggered.

[Shauna]

I am using the Telerik Grid's, with MVC3. These grid allow you to specify a error
event handler in case of an error. When a redirect occurs, after the session timeouts, this
function is not triggered, even though the redirect response is not in Json format.

  .Events(events => events.Error("error_handler"))

Note: error_handler is a js function which is not triggered.

Hi Shauna,

Current behavior is expected as the Grid is not aware of that the session is expired and the page is redirected - that why the desired behavior require custom solution (which is out of scope of our support service).

A non Json response should trigger the events.Error correct? The grid should error when the response is not in the correct/expect form of Json.

The problem is that the grid cannot parse the response, but instead of triggering the events.Error function, it does nothing. I doubt this is expected behavior.

Hi Shauna,

Basically it depends on your current implementation, however with the default settings if Ajax request call given controller Action and the session is expired, the action will try to redirect to the "login" page. That redirect will not be considered as "error". More information on the matter can be found in the following StackOverflow thread:
