Updating Multimple Rows In A Data Source

I have a sql data source that is filtered by a date range.  The results are then presented in a Gridview.  What I am hoping to do is add a button that will update all the filtered rows in the sql data source.  Is this possible?

The data source is shown below:

<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:MYSTR%>"

 SelectCommand="SELECT * FROM [dbo_cheques] WHERE (([chq_banked] >= @chq_banked) AND ([chq_banked] <= @chq_banked2))"

UpdateCommand="UPDATE dbo_cheques SET chq_printed = @chq_printed WHERE (chq_id = @chq_id)">

<SelectParameters>

<asp:ControlParameter ControlID="Calendar1" Name="chq_banked" PropertyName="SelectedDate"

Type="DateTime" />

<asp:ControlParameter ControlID="Calendar2" Name="chq_banked2" PropertyName="SelectedDate"

Type="DateTime" />

</SelectParameters>

<UpdateParameters>

<asp:Parameter Name="chq_printed" />

<asp:Parameter Name="chq_id" Type="Int32" />

</UpdateParameters>

</asp:SqlDataSource>
