RadAjaxManager MasterPages and AjaxRequestDelegate

[jose luis]

Hi,

in an scenario with a master page with the Radajaxmanager control and a content page with a grid i never get the Ajaxrequestdelegate event reach, in this case RadAjaxManager1_AjaxRequest, thanks a lot

the code behind of the content page:

       protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                RadAjaxManager AjaxManager = (RadAjaxManager)this.Master.FindControl("RadAjaxManager1");
                //                RadAjaxManager AjaxManager = RadAjaxManager.GetCurrent(Page);
                AjaxManager.AjaxSettings.AddAjaxSetting(AjaxManager, RadGridClientes);
                AjaxManager.AjaxSettings.AddAjaxSetting(RadGridClientes, RadGridClientes);
                AjaxManager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(RadAjaxManager1_AjaxRequest);
            }

        }

        protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            if (e.Argument == "Rebind")
            {
                RadGridClientes.MasterTableView.SortExpressions.Clear();
                RadGridClientes.MasterTableView.GroupByExpressions.Clear();
                RadGridClientes.Rebind();
            }
            else if (e.Argument == "RebindAndNavigate")
            {
                RadGridClientes.MasterTableView.SortExpressions.Clear();
                RadGridClientes.MasterTableView.GroupByExpressions.Clear();
                RadGridClientes.MasterTableView.CurrentPageIndex = RadGridClientes.MasterTableView.PageCount - 1;
                RadGridClientes.Rebind();
            }
        }

in the content page aspx file:


<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">



    <telerik:RadGrid ID="RadGridClientes" runat="server">
    </telerik:RadGrid>

                <telerik:RadButton Text="Cancelar" runat="server" ID="Cancelar" OnClientClicked="refreshGrid">
                </telerik:RadButton>

   <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function refreshGrid(arg) {
            if (!arg) {
                $find("<%= RadAjaxManager.GetCurrent(this.Page).ClientID %>").ajaxRequest("Rebind");
            }
            else {
                $find("<%= RadAjaxManager.GetCurrent(this.Page).ClientID %>").ajaxRequest("RebindAndNavigate");
            }
        }
    
    </script>
    </telerik:RadCodeBlock>
</asp:Content>

Hi jose luis,

The conditional statement on page load is adding a handler to the ajax request only when the page is loaded(not on postback). This way the handler would be attached and unloaded when the page unloads, it won't be persisted in further requests.
Therefore I would suggest you remove the conditional statement in the page load.

Let me know if this helps.
