GridView, SortedAscendingCellStyle server side databinding
<p>I try to use SortedAscendingCellStyle to assign the style of my gridView this is my ASP Code: </p>

<pre><code>&lt;asp:GridView ID="GridView1" runat="server" AllowSorting="True" CellPadding="4" OnSorting="GridView1_Sorting" AutoGenerateColumns="false"&gt;
            &lt;SortedAscendingCellStyle CssClass="SortedAscendingCellStyle" /&gt;
            &lt;SortedAscendingHeaderStyle CssClass="SortedAscendingHeaderStyle" /&gt;
            &lt;SortedDescendingCellStyle CssClass="SortedDescendingCellStyle" /&gt;
            &lt;SortedDescendingHeaderStyle CssClass="SortedDescendingHeaderStyle " /&gt;
            &lt;Columns&gt;
                &lt;asp:BoundField DataField="Nom" HeaderText="Nom" SortExpression="NOM"&gt;
                    &lt;ItemStyle Width="150px" /&gt;
                &lt;/asp:BoundField&gt;
                &lt;asp:BoundField DataField="Prenom" HeaderText="Prenom"&gt;
                    &lt;ItemStyle Width="150px" /&gt;
                &lt;/asp:BoundField&gt;
                &lt;asp:BoundField DataField="Pseudo" HeaderText="Pseudo"&gt;&lt;/asp:BoundField&gt;

                &lt;asp:BoundField DataField="Mail" HeaderText="Mail"&gt;
                    &lt;ItemStyle Width="140px" /&gt;
                &lt;/asp:BoundField&gt;
            &lt;/Columns&gt;
        &lt;/asp:GridView&gt;
</code></pre>

<p>there is no problem when i use DataSourceID, but when I use server side databining the SortedAscendingCellStyle Did Not work, this my code behind:</p>

<pre><code> protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                EmployeDAL oem = new EmployeDAL();
                this.GridView1.DataSource = oem.GetAll();
                GridView1.DataBind();

            }
        }
</code></pre>
