    I have a legacy .net application code using AjaxManager control associated with dropdowns and a button. It works fine with earlier versions of IE but when accessing the site through IE10 the dropdown doesnot cause a postback while the button control still works fine.Can you please suggest what could be the issue and how can it be fixed?

    below is the html generated for the dropdown(used alphabets for actual usercontrol names):

    <select name="a$b$c$lstddl" onchange="javascript:setTimeout(&#39;window['
                    a_b_c_RadAjaxManager1'].AsyncRequest(\&#39;a$b$c$lstddl\&#39;,\&#39;\&#39;)&#39;, 0)" id="a_b_c_c_listddl" style="width:310px;">

    Hello Surinder,

    I am afraid that based on the provided information it would be hard to pinpoint what is causing the behavior.

    Would you provide snippets of the relevant code so that we could try and reproduce the behavior locally?

    Also, please ensure that IE is not running in Compatibility Mode. This mode is using IE7 rendering and that is not supported.

    Hi Viktor,

    There are 4 dropdownlists lstA lstB etc and updating first one updates others using the dropdownlist selectedindexchanged event in code behind file:

    <rada:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <rada:AjaxSetting AjaxControlID="lstA">
                <UpdatedControls>
                    <rada:AjaxUpdatedControl ControlID="lstB"></rada:AjaxUpdatedControl>
                    <rada:AjaxUpdatedControl ControlID="lstC"></rada:AjaxUpdatedControl>
                    <rada:AjaxUpdatedControl ControlID="lstD"></rada:AjaxUpdatedControl>
                    <rada:AjaxUpdatedControl ControlID="pnlHelpText" LoadingPanelID="LoadingPanel1">
                    </rada:AjaxUpdatedControl>
                    <rada:AjaxUpdatedControl ControlID="radAjxPnl"></rada:AjaxUpdatedControl>
                    <rada:AjaxUpdatedControl ControlID="hdnParentFacilityEntitySelected"></rada:AjaxUpdatedControl>
                </UpdatedControls>
            </rada:AjaxSetting>
        </AjaxSettings>
    </rada:RadAjaxManager>
    <rada:AjaxLoadingPanel ID="LoadingPanel1" Style="padding-top: 20px" runat="server"
        Width="300" Height="75px">
        <asp:Image ID="Image1" runat="server" ImageUrl="~/RadControls/AJAX/Skins/Default/loading3.gif"
            AlternateText="Loading" BorderWidth="0px"></asp:Image>
    </rada:AjaxLoadingPanel>

    The RadAjax dll version is 1.0.3.0 and there are 2 js files with this dll RadAjax.js and RadAjaxNamespace.js. Please let me know if any other details are needed.

    Hi Surinder,

    It seems that you are using the classic RadControls. Note that they are outdated and are no longer supported.

    If you would like to target more modern browsers you should upgrade the controls to a recent version. The current version of the controls is 2016.1.113.
