[Solved] RadAjaxManager & Co F4.0

[Jean-Yves]

Hello,

I just begin a new project on the framework 4.0.

And my AJAX is not working at all and I don't understand why. May be I forgot an important step... But I don't see where.

So, it's easy, I have 1 masterPage and 1 page.

In the master page : 

    <telerik:RadScriptManager id="RadScriptManager1" runat="server">
    <Scripts>
            <asp:ScriptReference assembly="Telerik.Web.UI" name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference assembly="Telerik.Web.UI" name="Telerik.Web.UI.Common.jQuery.js" />
        </Scripts>
    </telerik:RadScriptManager>

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadTextBoxRecherche" EventName="RadTextBoxRecherche">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="DivContent" />
                    <telerik:AjaxUpdatedControl ControlID="DivRecherche" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

    <telerik:RadAjaxLoadingPanel id="RadAjaxLoadingPanel1" runat="server" />

    <telerik:RadTextBox ID="RadTextBoxRecherche" runat="server" Width="230px" Height="25px"
                    EmptyMessage="...Rechercher" EmptyMessageStyle-Font-Size="Medium" Font-Size="Medium"
                    ontextchanged="RadTextBoxRecherche_TextChanged">
                        <EmptyMessageStyle HorizontalAlign="Right" Font-Size="Medium"></EmptyMessageStyle>
                        <ReadOnlyStyle HorizontalAlign="Right"></ReadOnlyStyle>
                        <FocusedStyle HorizontalAlign="Right"></FocusedStyle>
                        <DisabledStyle HorizontalAlign="Right" />
                        <InvalidStyle HorizontalAlign="Right"></InvalidStyle>
                        <HoveredStyle HorizontalAlign="Right"></HoveredStyle>
                        <EnabledStyle HorizontalAlign="Right" />
                </telerik:RadTextBox>

 <asp:ContentPlaceHolder ID="ContentPlaceHolderContent" runat="server">
 </asp:ContentPlaceHolder>

<div id="DivContent" runat="server">
Test 1
</div>

<div id="DivContent" runat="server">
Test 2
</div>

and 

protected void RadTextBoxRecherche_TextChanged(object sender, EventArgs e)
        {
            if (!String.IsNullOrWhiteSpace(RadTextBoxRecherche.Text))
            {
                gestionRecherche(true);
            }
            else
            {
                gestionRecherche(false);
            }
        }

        private void gestionRecherche(bool b)
        {
            DivContent.Visible = !b;
            DivRecherche.Visible = b;
        }

And in the page : 

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadTextBoxSociete">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="ImageSocieteGood" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>

<telerik:RadTextBox ID="RadTextBoxSociete" runat="server" OnTextChanged="RadTextBoxSociete_TextChanged" AutoPostBack="true"></telerik:RadTextBox>
                        <asp:Image id="ImageSocieteGood" runat="server" ImageUrl="/Images/fam/good.png" Visible="false" />
                        <asp:Image id="ImageSocieteError" runat="server" ImageUrl="/Images/fam/error.png" Visible="false" />

and 

protected void RadTextBoxSociete_TextChanged(object sender, EventArgs e)
        {
            ImageSocieteGood.Visible = true;
        }

So, as you see it's very simple situations.

But both don't work... and I don't know why.

Thank you
