Any one with the solution plz

Did you have any further information about the exception? Can you track it back to what in your code was causing the problem?

Did you have any further information about the exception? Can you track it back to what in your code was causing the problem?

actually i m using ActiveX GridView, Every page where i placed that GridView is giving same error, I just wanna know that, How can i change application trust level, Where my host has refused to change the system web.config to FULL, is there any other way i can use, Please help

aliusmankhan:

actually i m using ActiveX GridView

Could you explain more?  Why are you using that?

I suggest that you replace the ActiveX control with its ASP.NET equivalent.

Hi,

The error message indicates that your website doesn't have rights to access the resource on server.

Commonly, the host server uses Medium trust level to restrict which resource types your application can access and which privileged operations it can perform.
 
During development in local, the code access security is Full trust level and application can implement more works. For testing, you can run your website with Medium trust level in local. I think we will get the same issue.

<system.web>
  ...
  <trust level="Medium" />
  ...
</system.web>

For more information, see http://msdn.microsoft.com/en-us/library/ms998326.aspx (Typically, Table 4: Default ASP.NET Policy Permissions and Trust Levels).

You also can ask you Host Company to confirm whether they support Full trust website or find other host server that supports it.
 
I look forward to receiving your test results.

Thank you Thomas for the reference to http://msdn.microsoft.com/en-us/library/ms998326.aspx

It stated: If your application calls unmanaged code, it must run with Full trust.

Thus active X will not run in a medium trust web site (or application).

Yes i know all about it, but here i just wanna know that how can i give my application Full trust level progmatically, Where my host does not support Full trust level.

Because i was needed some facilities which the asp.net Grid was not giving.. I really cant get rid of it,

No i really cant get rid of that, Cuz i need them in my application to perform some very necessary functions , which is not possible with standard Grid.

Hi,

Thanks for your response.

Since your host server doesn't allow Full truest level, they will lock it in machine level config file, and you cannot modify it in your web.config programmatically.

Thanks.
