I have a query in sql server as below :

Alter procedure testprocedure
As
Begin
select column_date, sum(qty1), sum(qty2), sum(qty3) from table1
End
Go

I used the code below to access the stored procedure in asp.net. Even i copied this code from another source but it worked for me.

        ID="SqlDataSource1"  
        runat="server"  
        ConnectionString="<%$ ConnectionStrings:databasename %>"  
        SelectCommand="testprocedure"  
        SelectCommandType="StoredProcedure"  
        >  
    </asp:SqlDataSource>  
    <asp:GridView   
        ID="GridView1"

        AllowPaging="true"  
        PageSize="31"  
        BorderColor="Salmon"

        Width="650"  
        >  
        <HeaderStyle BackColor="IndianRed" ForeColor="Snow" Height="45"/>  
        <RowStyle BackColor="DarkSalmon" ForeColor="Snow" Font-Italic="true" />  
        <PagerStyle   
            Height="45"   
            HorizontalAlign="Right"   
            BackColor="RosyBrown"  
            Font-Bold="true"  
            Font-Size="X-Large"  
            ForeColor="Snow"  
            />  
        <PagerSettings Mode="Numeric" />  
    </asp:GridView>  
</div>  
</form>  
</body>  
</html>

Now I altered my query like this for accepting date in parameters :

Alter procedure testprocedure @startdate nchar(8), @enddate nchar(8)
As
Begin
select column_date, sum(qty1), sum(qty2), sum(qty3) from table1
where column_date between @startdate and @enddate
End
Go

Please note my date column has data type nchar(8).
Now I would like to alter the previous asp.net code posted above to accept this parameter for dates. I don’t know to edit the code as I’m very new asp.net and still learning.
