Can I use a defaultvalue for an ObjectDataSource Update-Parameter?

Question

Can I use this ASPX-code in defining my ObjectDataSource control?

<UpdateParameters>
   <asp:Parameter Name="UID_KEY" Type="Int32"  DefaultValue="<%= hidUID_KEY.V"ALUE %>"/>

I am not fluent in the "ASP" special tags (<%= or <%...other tags, not sure if <%= is the correct syntax.) Further...must I convert the hidden-control-STRING to an Int32?
If so, please show me how to cast it within the above ASPX code. Thanks...John

Here is the example and the URL for more detail to use asp.net inline expression.

 <asp:Parameter Name="UID_KEY" Type="Int32"  DefaultValue="<%= Convert.ToInt32(hidUID_KEY.Value) %>"/>
