@MrChief had the idea above about the ugly hack...I put that together. Here is the main code that I used to do this. It does, indeed, hijack the ajax call before it is put on the wire. The key is to modify the URL that is getting sent because the grid will grab that URL from HttpContext.Request.Path. and plug it into the onclick for the anchor element.

I put this into my main common.js and will simply attach a function to capture the ajaxSend event which happens just before the data is sent.

// Used to hijack the sending of all AJAX calls.  Before it sends the call to the server, it checks to see if the 
// active element (the element that prompted the call) is marked with a given class.  If so, then it will perform
// the given operation.  
$(document).ajaxSend(function (event, jqXHR, ajaxOptions) {

    var activeElement = document.activeElement;

    if ($(activeElement).attr('redosorturl') != null) {

        // If this is a sort anchor link from a grid that needs to have the sort link redone, do it here.
        // the code is in the eipGrip.js file.
        if ($(activeElement).attr('redosorturl').toString() == 'redoSortURL') {
            var newURL = RedoGridSortURL(activeElement, ajaxOptions.url.toString());
            ajaxOptions.url = newURL.toString();
        }
    }

    return false;
});

When rendering the page, I have marked the tag in column header that contains the incorrect URL with a class named "redosorturl', so I know when I hijack the ajax call, the operation has to be done on this element. I then call a custom function that gives me the correct URL, then the ajaxOptions.url is then rewritten with that new URL.

I have to pass the activeElement to that rewrite function so I can traverse up the DOM to get the grid information, where I have put data like the controller and action method that is used along with and IDs and other info that I use for the URL. Likewise, I pass in the current url string because the grid will inject a token at the end of the url that I parse off and put on the new url.
