    I have a very simple page that includes a RadComboBox tied to a SqlDatasource.

    As soon as I attempt to add AJAX Manager (v2011.2.712.40) to the page, the combo box is non-reponsive.

    If I configure the Manage by turning off the "Enable Ajax" option, the page returns to normal operation.

    Where would I start looking for configuration or other areas that might cause Ajax to fail?

    Bear in mind, I have had great success with all of these components in several other projects, so I am sure the workstation is configured correctly.

    This problem persists across the latest versions of IE, Firefox and Chrome, yet another reason to suspect my configuration.

    The other possibly relevant details are: VS2010 Pro, IIS 7.5 on Win 7 Pro, coding in VB, targeting ASP.NET 4.0. (all updated as of this morning)

    Hello Tomica,

    I have tried the following aspx and which worked as expected. Please make a double check with your code.
    <form id="form1" runat="server">
       <asp:ScriptManager ID="ScriptManager1" runat="server">
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <telerik:AjaxSetting AjaxControlID="RadCboCategories">
                        <telerik:AjaxUpdatedControl ControlID="RadComboBox1" />
        <telerik:RadComboBox ID="RadComboBox1" runat="server" Width="100px" Skin="Default"
            MarkFirstMatch="True" AutoPostBack="true" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
                <telerik:RadComboBoxItem Text="AND" Value="AND" />
                <telerik:RadComboBoxItem Text="OR" Value="OR" />
                <telerik:RadComboBoxItem Text="Not" Value="Not" />
                <telerik:RadComboBoxItem Text="XOR" Value="XOR" />

    Hope it helps.
