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:

C#

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:

C#

Server Error in '/' Application.
Security Exception

If somebody can help me, pls let me know...

Looks like your Sys Admin is the one to help you. As the error says, it's a permissions issue. So talk (or email or communicate in some way) with your server admin and ask for the required permissions to use the ASPxGauge control. If you are the server admin, look up in Google how to give yourself the required permissions. I don't see that this is really an issue with your code.

Hope this helps,
Ed

Hello Ed,

We have already called the server admin to ask whether they could change the security level because it was the highest one. They said yes...but then if the security level is low and that would be problem for our project and we could be able to lose all of our codes of the project.

I just wanted to know whether there is any another way for that...

Error looks self explanatory: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Looks like you don't have permission to save file on server.
