Global error handler for numerous grids

[Steve]

I've currently inherited an application which has numerous Kendo grids (and other controls) throughout, and I'm trying to fix an error which keeps cropping up now and again - specifically when the user is no longer authenticated.

I know what the solution is for a single instance of the control - return a flag to indicate authentication failed, and then detect this in the error handler and perform the authentication.

The problem is am I really going to have to handle this for every instance of a Kendo control I have? Is there not a global error handler I can hook into for the DataSource? Or the grid or all Kendo controls?

This would be a more straighforward short term solution than refactoring everything to specific error handlers, etc.

Hello,

You could specify a default error handler for the dataSource e.g.

kendo.data.DataSource.prototype.options.error = function (e) {
   //your logic
};

Thanks Daniel. Looks like an interesting solution. I actually received a response on StackOverflow which I've just implemented and which works well. It has the added bonus of hooking into all Ajax on the site - not just the Kendo controls.

But your solution would come in handy just for handling Kendo DataSource errors.
