I get a Object required generic error in IE

 

Using Firebug in Firefox gave me this

this._foregroundElement is null

Make sure you have the CancelControlID="btnCancel" and OKControlID = "btnOK" in the mpe control. Please post some code if this doesn't work.

Hi helixpoint,

What my thought of the issue is you have set the DropShadow property with true and not set the BackgroundCssClass property’s value.

Please modify your ModalPopupExtender’s tag as this: 

        <ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender" runat="server"
            TargetControlID="LinkButton1"
            PopupControlID="Panel1"
            BackgroundCssClass="modalBackground"
            OkControlID="OkButton"
            OnOkScript="onOk()"
            CancelControlID="CancelButton"
            DropShadow="true"
            PopupDragHandleControlID="Panel3" />

    <style type="text/css">
        .modalBackground
        {
            background-color: Gray;
            filter: alpha(opacity=70);
            opacity: 0.7;
        }
    </style>

Please let me know the result.

Best regards,
