Where to store currently selected item id?
<p>I'm trying to write an asp.net app which searches a sql db and returns/updates the data.</p>

<p>I want to be able to hold the currently selected id of the item my user has selected. For example a doctors surgery would select a patient record then be able to browse the app without having to re-select that patient on each page.</p>

<p>What would be the best way to do this. Ideally I need to be able to get this ID application wide. the only thing i can think of is to create a public class, store the id and make it public but this seems quite messy</p>

<p>Thank you </p>
