<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="nFormatin">
<class name="nFormation.Devise, nFormation" table="T_DEVISE">

<id name="clsDevise" unsaved-value="1">
<column name="deDevise" sql-type="nvarchar(10)" not-null="false"/>
<generator class="native"/>
</id>

<property name="clsDesignation" type="String">

</property>

<property name="clsPays" type="String">
<column name="Pays"/>
</property>

</class>
</hibernate-mapping>

public Devise(String Devise, String Designation, String Pays)

private void btnModifier_Click(object sender, EventArgs e)
{
ISession s = NhibernateSessionFactory.openSession();
ITransaction tx = s.BeginTransaction();
Devise d = new Devise(txtDevise.Text, txtDesignation.Text, txtPays.Text);


s.Update(d, txtOldId);
