I am trying to get an `asp:SessionParameter` of a `SelectParameters`, to use a property of an object in session
instead of having a string in the session like `Session["CustomerID"]` 

Something like `Session["Customer"]` where the property is ((Customer) `Session["Customer"]).CustomerID)`

I don’t know the syntax to do that, if you can help, I’d really appreciate it

Thank you

My code:

```
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:DBConnectionString %>" xmlns:asp="#unknown"> SelectCommand="SELECT * FROM getStoreCustomers (@customerID,@week,@day)"
ProviderName="System.Data.SqlClient">
<selectparameters>
<asp:sessionparameter name="customerID" sessionfield="Customer" /> ?????? (what is the syntax to pass the property here?)
<asp:controlparameter controlid="ddWeek" defaultvalue="-1" name="week" propertyname="SelectedValue" /> <asp:controlparameter controlid="ddDay" defaultvalue="-1" name="day" propertyname="SelectedValue" /> </selectparameters>

```

The class I use is like any other class (but serializable)

```
[Serializable]
public class Customer
{
public int CustomerID
{
get;
set;
}
} 

```
