How to count selected items in RadGrid

[IT]

Hopefully this is a simple question.


I've got Radgrid (Ajaxed) and with Paging enabled

How do I create a label on the page and then have the label updated with the count of all selected items


I've correctly got this javascript attached to the RadGrids (ClientEvents - onrowcreated, onrowdeselected, onrowselected)

 var rgGrid = $find("<%= RadGridBirthdays.ClientID %>");
               var MasterTable = rgGrid.get_masterTableView();
               var selectedRows = MasterTable.get_selectedItems();
               document.getElementById('<%= this.SelectedCount.ClientID %>').innerHTML = selectedRows.length;

The problem is when i go to the next page my count resets so the actual count is never correct.


Can someone please explain how to get the count (the correct way ) with paging enabled.

Hello Brian,

To learn how to achieve the desired functionality, please take a look at the Persisting the selected rows server-side on sorting/paging/filtering/grouping or at the Persisting the selected rows client-side on sorting/paging/filtering/grouping help topics depending on the way of selection.
I recommend that you also have an asp:HiddenField holding the count of selected indexes on all pages and update it and the label as well on paging.

You wouldnt happen to have an example of such a operation

Would prefer to do most of this client side if possible 

What I am doing is taking the selected items and then using them on another page (but as the selected items are not saving between pages I need get the right number of items back)

If i've got a hidden field which I take it will save the item keyvalues? then i can use the field to fill a session arraylist that i'm using on the next aspx page.
