You can try like below.

XML

<asp:SqlDataSource ID="ProductsFilteredByPriceDataSource" runat="server"
    ConnectionString="<%$ ConnectionStrings:NORTHWNDConnectionString %>"
    SelectCommand=
        "SELECT ProductName, UnitPrice
        FROM Products WHERE UnitPrice <= @MaximumPrice">
    <SelectParameters>
        <asp:ControlParameter ControlID="MaxPrice" Name="MaximumPrice"
            PropertyName="Text" />
    </SelectParameters>
</asp:SqlDataSource>
