System.Security.SecurityException occured in iexplore


Recommended Posts


Recently, the IE closes automatically when refreshing the ChartFX with data. In PC with visual studio, it shows "System.Security.SecurityException" occured in iexplore.exe,

{"Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."}


  what is the reason for this error?

I Assume you are using the .Net client control to render the chart, correct? How are you manipulating the data? Are you doing something at the client side using Java script? Are you using Ajax to bring new data from the server?

 The error you mention may indicate trust issues on the client side. If you are indeed manipulating the chart object on the client side, you need to make sure you have the .Net trust set to full. Can you please verify your .Net trust settings for the zone in which the page is running?
