Hello, i'm trying to implement a exception handling system on my application.
But i'm getting an error on firebug related to grid
syntax error
what i'm trying to do catch all exception custom or not and on base controller send it a custom ascx file that will present my custom error messages.
i'm using a base controller whit the following
| protected override void OnException(ExceptionContext filterContext) |
| { |
| // Output a nice error page |
| if (filterContext.HttpContext.IsCustomErrorEnabled) |
| { |
| filterContext.ExceptionHandled = true; |
| this.View("Error", filterContext).ExecuteResult(this.ControllerContext); |
| } |
| } |
than on my child controller i have an action that is responsible for insert a new row in database,
i have a try catch block that will catch sqlexception and throw a custom exception
after that the OnException of base controller is called and so the Error View ascx, on firebug i see the response containing the Error View Html but it is not rendered and the js error is showed in firebug.
someone now how to achieve this?
Best Regards
Marco

Hello Marco,
The grid does not know how to handle the HTML which you return from the error handler. It expects JSON if the HTTP status code is 200 (which is the default case). In case of error HTTP status 500 is expected by the grid (you can test by throwing exception in the action method which feeds the grid with data for the ajax binding). Then the grid will display a message box telling that an exception has occurred. You can override that by handling the onError client-side event and preventing the default behavior.
<%= Html.Telerik().Grid()
.ClientEvents(events => events.OnError("onError"))
%>
<script type="text/javascript">
function onError(e) {
e.preventDefault();
alert("Server error!");
}
</script>
I think that the HTTP status code remains 200 when you render the error page. I think that if you can get it to 500 the grid will properly handle the error. Then you can handle the OnError event and act accordingly.
