    I am getting the following javascript error when my radmenu loads : Error:Unable to get property 'addEventListener' of undefined or null reference

    This causes some (not all) of the children menu items to not show up. Only 2 dropdowns (children) work and the rest do not drop down.

    Is there any way to fix this? I have tried so many things but no luck.

    Using IE 11    ASP.net 2.0 C# code.

    Hi May,

    Such errors are expected when IE is running in Compatibility mode (which is not supported as well). Can you, please, make sure that this is not the case at your end?
