Update values in a content page are not working

[Fabian Raul Jofre]

Hello,
 I have a project using master page and Ajax.
In the master page i  use RadComboBox to select language of my application, for example English to Spanish.
I have a problem when I try to change a language from the RadComboBox.
The page of the ContentPlaceHolder contain RadGrid, and everything function ok, but not update the values of the RadGrid Header-Text control from one language to another.

This is a part of the code of master page:
*****************

<

 

asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

 

 

<telerik:RadAjaxPanel ID="RadAjaxPanel10" runat="server">

 

 

<telerik:RadComboBox Width="250px" ID="cmbMultiLenguage" runat="server" ZIndex="99999" Skin="Forest" Font-Size="11px" AutoPostBack="true"/>

 

 

</telerik:RadAjaxPanel>

 

 

<asp:ContentPlaceHolder ID="Contenedor" runat="server">

 

 

 

 

 

</asp:ContentPlaceHolder>

This is a Part .aspx & .cs of the page (ContentPlaceHolder):

Thank's if you can help me.

Hello Fabian,

I suggest that you use RadAjaxManager to ajaxify your application. To achieve it, remove the RadAjaxPanels wrapping the RadComboBox and the RadGrid and try the below ajax settings:

in the master page:

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

in the content page:

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

in the content  page code behind:

protected void Page_Load(object sender, EventArgs e)
{
    RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);
    Control combo = this.Page.Master.FindControl("RadAjaxManager1");
    manager.AjaxSettings.AddAjaxSetting(combo, RadGrid1);
}

Hi Fabian,

Could you please confirm that it works properly without any ajax at all? I would suggest that you try sending the master and the content pages so I could try replicating your scenario and issue on my end and find a proper solution for you.
