Hello guys, There is a problem that I added a few AspxGauges to my project. I set the customize Gauge control and save them out as XML. The page load is below:

    protected void Page\_Load(object sender, EventArgs e)
    {
            this.gauges\_yil.RestoreLayoutFromXml(MapPath("~/aspx/gauges\_yil.xml"));
            this.gauges\_m2.RestoreLayoutFromXml(MapPath("~/aspx/gauges\_m2.xml"));
            this.gauges\_kasa.RestoreLayoutFromXml(MapPath("~/aspx/gauges\_kasa.xml"));
            this.ASPxGaugeControl4.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl4.xml"));
            this.ASPxGaugeControl5.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl5.xml"));
            this.ASPxGaugeControl6.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl6.xml"));
            
    }

However, I got this error after I sent it to the server: Server Error in '/' Application. Security Exception Description: The application attempted to perform an operation not allowed by the security policy.
