    I am using Teleriks' 2014.2.618 version. Earlier, I was using 2012 ones. 

    I have ContextMenu on RadGrid which is suppose to open a menu. It worked perfectly fine on 2012 version. However, on 2014, the ContextMenu doesn't open up. While debugging our javascript its breaks at contextmenu.showAt(100,100). 

    We verified the passing parameter as integer. We pass the RadGrid's Id as sClientId.

    It throws error as : Unable to get property 'showAt' of undefined or null reference 

    var x = 0;
    var y = 0;

    function showMenu()
            x = e.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
            y = e.clientY + document.body.scrollTop + document.documentElement.scrollTop;

            var contextMenu = $find(sClientId);
            contextMenu.showAt(x, y);

    Hi Prachi,

    Unfortunately I couldn't replicate the issue at my end. Please try the below sample code snippet which works fine at my end.

    <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" GridLines="None"
        AllowSorting="True" AllowPaging="True" PageSize="50" Width="900px">
            <ClientEvents OnRowContextMenu="RowContextMenu" />
            <Selecting AllowRowSelect="true" />
            <Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="true" FrozenColumnsCount="2">
        <HeaderStyle Width="225px"></HeaderStyle>
        <PagerStyle PageSizeControlType="RadDropDownList" Mode="NextPrevAndNumeric"></PagerStyle>
    <telerik:RadContextMenu ID="RadMenu1" runat="server" EnableRoundedCorners="true"
            <telerik:RadMenuItem Text="Quick view">
            <telerik:RadMenuItem Text="Add" Value="add">
            <telerik:RadMenuItem Text="Edit" Value="edit">
            <telerik:RadMenuItem Text="Delete" Value="delete">

    function RowContextMenu(sender, eventArgs) {
        var x = 0, y = 0;
        var menu = $find("<%=RadMenu1.ClientID %>");
        var evt = eventArgs.get_domEvent();
        x = evt.rawEvent.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
        y = evt.rawEvent.clientY + document.body.scrollTop + document.documentElement.scrollTop;
        menu.showAt(x, y);
