I have Master Page I use with certain projects. I add AjaxManager to the a content page and when I configure it shows no controls in the project. I have tried to move the Manager to all the different MasterPage areas with no luck. From what I've read I should be able to run ajax on any controls within the same content area without any problems. I am using AjaxManager v2009.2.826.35. Here is a test sample:

    
            <%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="Login.aspx.vb" Inherits="_Default" title="Untitled Page" %> 
        
            <%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %> 
        
            <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">  
        
            </asp:Content> 
        
            <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">  
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server">  
        
                </telerik:RadScriptManager> 
        
                &nbsp; &nbsp;&nbsp; &nbsp;<br /> 
        
                <br /> 
        
                <telerik:RadDatePicker ID="RadDatePicker1" Runat="server"   
        
                    Culture="English (United States)">  
        
            <Calendar UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x"></Calendar> 
        
            <DatePopupButton ImageUrl="" HoverImageUrl=""></DatePopupButton> 
        
                </telerik:RadDatePicker> 
        
                <br /> 
        
                <br /> 
        
                <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1"   
        
                    GridLines="None" Width="228px">  
        
            <MasterTableView AutoGenerateColumns="False" DataKeyNames="ID"   
        
                        DataSourceID="SqlDataSource1">  
        
            <RowIndicatorColumn> 
        
            <HeaderStyle Width="20px"></HeaderStyle> 
        
            </RowIndicatorColumn> 
        
            <ExpandCollapseColumn> 
        
            <HeaderStyle Width="20px"></HeaderStyle> 
        
            </ExpandCollapseColumn> 
        
                <Columns> 
        
                    <telerik:GridBoundColumn DataField="ID" DataType="System.Int32" HeaderText="ID"   
        
                        ReadOnly="True" SortExpression="ID" UniqueName="ID">  
        
                    </telerik:GridBoundColumn> 
        
                    <telerik:GridBoundColumn DataField="DevDesc" HeaderText="DevDesc"   
        
                        SortExpression="DevDesc" UniqueName="DevDesc">  
        
                    </telerik:GridBoundColumn> 
        
                </Columns> 
        
            </MasterTableView> 
        
                </telerik:RadGrid> 
        
                <asp:SqlDataSource ID="SqlDataSource1" runat="server"   
        
                    ConnectionString="<%$ ConnectionStrings:SCCSDConnectionString %>"   
        
                    SelectCommand="SELECT [ID], [DevDesc] FROM [tblDevices]">  
        
                </asp:SqlDataSource>

            </asp:Content>

Pavlina,

Thanks for the quick response. I have looked at those examples before but revisited. In reading about Content Pages I read:

"...... one can add RadAjaxManager control in any ContentPage. Unfortunately not all possible scenarios can be handled when using RadAjaxManager this way - for example a control in the master page cannot be ajaxified. RadAjaxManager can handle only cases when there controls to ajaxify are beneath in the manager control hierarchy"

In my test example code I have no controls in anyting but a content page. I am not trying to ajaxify any controls execpt under the AjaxManager within the same content page. When I go to AjaxManager Configuration, it shows no controls listed.

I did try the RadAjaxManager in the Master Page and RadAjaxManageProxy in the Content Page as the example you sent me listed, with the same result.

I am just not sure how I should continue from here. I have talked with another developer that says he uses the RADAjaxManager with MasterPages/ContentPages without any problems.

Thanks for your help,
Lee
