protected System.Web.UI.WebControls.TextBox txtPrenom;
protected System.Web.UI.WebControls.TextBox txtNom;
protected System.Web.UI.WebControls.TextBox txtCourriel;
protected System.Web.UI.WebControls.TextBox txtAdresse;
protected System.Web.UI.WebControls.TextBox txtVille;
protected System.Web.UI.WebControls.TextBox txtProvince;
protected System.Web.UI.WebControls.TextBox txtPays;
protected System.Web.UI.WebControls.TextBox txtCodePostal;
protected System.Web.UI.WebControls.TextBox txtTelephone;

in my page_load I do something like this :

txtNom.Text = objUsager.Nom;
txtPrenom.Text = objUsager.Prenom;
txtCourriel.Text = objUsager.Courriel;
txtAdresse.Text = objUsager.Adresse;
txtVille.Text = objUsager.Ville;
txtProvince.Text = objUsager.Province;
txtPays.Text = objUsager.Pays;
txtCodePostal.Text = objUsager.CodePostal;
txtTelephone.Text = objUsager.NoTel;

But when I try to get back the "change" in the texte box in

private void cmdUpdate_Click(object sender, System.EventArgs e)
{
    objUsager.Nom = txtNom.Text;
    objUsager.Prenom = txtPrenom.Text;
    objUsager.Courriel = txtCourriel.Text;
    objUsager.Adresse = txtAdresse.Text;
    objUsager.Ville = txtVille.Text;
    objUsager.Province = txtProvince.Text;
    objUsager.Pays = txtPays.Text;
    objUsager.CodePostal = txtCodePostal.Text;
    objUsager.NoTel = txtTelephone.Text;
    objUsager.Update();
}

I only get the value I had in my page load and not the modification I've made in the page...

Is there somebody who know why and howto fix this?

I solve my problem by putting a if(!IsPostBack) before

txtNom.Text = objUsager.Nom;
txtPrenom.Text = objUsager.Prenom;
txtCourriel.Text = objUsager.Courriel;
txtAdresse.Text = objUsager.Adresse;
txtVille.Text = objUsager.Ville;
txtProvince.Text = objUsager.Province;
txtPays.Text = objUsager.Pays;
txtCodePostal.Text = objUsager.CodePostal;
txtTelephone.Text = objUsager.NoTel;

In my page load

Thanks again
