Solution 1

<%# Eval("order_id") %> is more than enough I guess. Remove the "=" from the expression.

Use SelectParameter

XML

<asp:SqlDataSource ID="SqlDataSource3" runat="server"
       ConnectionString="<%$ ConnectionStrings:OpticsConnectionString %>"
       SelectCommand="SELECT [pro_name],
       [pro_purchased_qty], [pro_sale_price], [Purchases_price]
       FROM [rpt_UVU_allOrders_In_Details_R] WHERE ([order_id] = @order_id)">
       <SelectParameters>
            <asp:Parameter Name="order_id" />
       </SelectParameters>
</asp:SqlDataSource>

You can apply parameter value from code behind.

<code>
SqlDataSource3.SelectParameters["order_id"].DefaultValue = "value";
</code>

Beside SelectParameter offers few built-in parameter types.
