I have an aspxpopupcontrol

<dx:ASPxPopupControl ID="popupTest" runat="server" Width="750px" ClientInstanceName="popTest"
                    AllowDragging="true" Modal="true" PopupVerticalAlign="TopSides" PopupHorizontalAlign="NotSet"
                    HeaderText="Test" SkinID="pop_Olive" CloseAction="CloseButton">
                    </dx:ASPxPopupControl>

The pop up gets opened and I am able to close the pop up. CloseAction works well in firefox and Chrome. in IE it works in lower version but it is not working in IE 10. Please help me on this regard. Very urgent issue........
