Question

I have a page that uses GridView to display some data taken from a stored procedure

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DBConnectionString1 %>"
            SelectCommand="p_get_all_students" SelectCommandType="StoredProcedure">
        </asp:SqlDataSource>

One of the columns returned is studyYear with the possible values: 1,2,3

I would like to add a set of 3 checkboxes to allow filtering of the displayed results by the studyYear

How could I do this?

Ideally I would like to keep the stored procedure as p_get_all_students and only filter the displayed information – so there would be only one initial call to the database.

EDIT
The number of rows returned by the stored procedure is from 20 to 200

I’d personally change the way the app was architected. If you want to keep the code the same though, you could hook into the RowDataBound event.

Update- here’s an example which should help you.
