Determine Selected Item and Current Page of Telerik MVC Grid - Client Side

Question

I am using the Telerik MVC grid, with Ajax data binding.

I would like to do 2 things with the Telerik MVC Grid:

When a row is selected, detect (client side) which page the grid is currently on as well as which row was selected.
The next time the grid is loaded (using ajax ... I never leave the page), page back to the same page to show the last select. (I guess I am really just asking if there is a way to immediately go to a page of the grid once the data is loaded, rather than page 1)

Please keep in mind, I am aware of the client side events already. I would like to know how to do #1 from the event, and #2 either from the client side or programatically somehow.

Edit/More Details: I think I know what I need to do here. Since I am using Ajax loading here, the Ajax POST is being called somewhere in the Telerik code. I can see that during that Ajax POST they are sending a "page" parameter to the controller. If I could edit that somehow, I am sure it would work - but I am having trouble changing that parameter.

Thanks in advance!

For the sake of anyone else looking for this, I figured it out:

Getting the current page of the Grid: To do this, I use jQuery to determine which number has the "selected" style (t-state-active) to determine the current page number. Example (my grid id is 'cases-grid'):

function getCurrentGridPage() {
        ///<summary>Gets the current page of the #cases-grid</summary>
        var page = $('#cases-grid .t-state-active');
        if (page.length == 0) {
            return 1; //default to page 1 when unknown
        }
        return page.text();
    }

The second part of my question was actually well documented on the Telerik site ... I just missed it for awhile. To load the grid to a specific page (other than 1) I added the following to my grid:

.Pageable(pager => pager.PageTo(@Model.InitialPage))

And added the InitialPage property to my model.
