                            <table style="height: 100%; width: 100%">
                                <tr>

                                <tr>
                                    <td align="center" valign="bottom">
                                        <input id="btnClose" type="button" value="Fermer" onclick="HideDiv()" class="button" />

                                </tr>
                            </table>
                        </div>
                    </div>

Quand je clique sur le bouton consulter de ma gridview :

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
protected void listeStations_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Consulter")
        {
            //remplir details/paiement/echange/corresps
            //activer details panel
            int id = Convert.ToInt32(e.CommandArgument);
            HiddenFiltre.Value = id.ToString();
            lblresult.Text = "";
 
            chargerDonnees(id.ToString());
            fillGridCorresps(id.ToString());
            filleRepeatPhoto(id.ToString());
 
        }
    }

les deux methodes chargerDonnees(id.ToString());fillGridCorresps(id.ToString()); s'executent avec succes
MAis la methode filleRepeatPhoto(id.ToString()); s"execute mais mes images ne s"affichent que si je clique sur le bouton telecharger.

Code:

1
2
3
4
5
6
7
8
9
10
11
private void filleRepeatPhoto(string id)
    {
        string queryPhoto = "SELECT * FROM Photos WHERE ID = " + id;
 
        SqlDataAdapter da = new SqlDataAdapter(queryPhoto, connection);
        DataTable dt = new DataTable();
        da.Fill(dt);
        repeatPhotos.DataSource = dt;
        repeatPhotos.DataBind();
 
    }

vous avez une idee ?
