Hi guys,

First of all, sorry for the long post.

I'm having a problem with a custom module. At the moment we're creating a bunch of custom modules and coming across the following Exception on a redirect in the first one:

A critical error has occurred.
Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

A look into the Log Viewer shows a Page Load Exception with the following details:

The problem occurs post-save on an item content. the content is 2 text boxes, one with name (string) and one with a reference (string). The two are set as props in a class (CodeInfo) and the controller class (CodeController) saves it through a SqlDataProvider to a SQL 2005 Server. Once all those bits and pieces are done it does a Redirect back to the content page (Response.Redirect(NavigateUrl(), true)) and shows the content list again. it is displaying the content just fine, however, above the module (there is only one module on the page) it displays the critical error above. The full code for the event handler after which the error occurs is:

/// <summary>
/// Handles the <see cref="LinkButton.Click"/> event for the <see cref="EditCode.Update"/>
/// <see cref="LinkButton"/>.
/// </summary>
/// <param name="sender">The <see cref="Object"/> source of the event.</param>
/// <param name="e">An <see cref="EventArgs"/> that contains event data.</param>
protected void Update_Click(object sender, EventArgs e)
{
   try
   {
      CodeInfo itemInfo = new CodeInfo();
      itemInfo.Id = this._id;
      itemInfo.Name = this.Name.Text;
      itemInfo.Reference = this.Reference.Text;
      itemInfo.CreatedByUser = this.UserId;
      if (this._id == 0 || DotNetNuke.Common.Utilities.Null.IsNull(this._id))
         CodeController.AddCode(itemInfo);
      else
         CodeController.UpdateCode(itemInfo);
      // refresh cache
      this.SynchronizeModule();
      this.Response.Redirect(Globals.NavigateURL(), true);
   }
   catch (Exception ex)
   {
      Exceptions.ProcessModuleLoadException(this, ex);
   }
}

The problem occurs whether adding a new code or updating an existing one, or even when you cancel (in the edit screen) or delete a code.

Here is the code for the cancel and delete handlers:

/// <summary>
/// Handles the <see cref="LinkButton.Click"/> event for the <see cref="EditCode.Cancel"/>
/// <see cref="LinkButton"/>.
/// </summary>
/// <param name="sender">The <see cref="Object"/> source of the event.</param>
/// <param name="e">An <see cref="EventArgs"/> that contains event data.</param>
protected void Cancel_Click(object sender, EventArgs e)
{
   try
   {
      this.Response.Redirect(Globals.NavigateURL(), true);
   }
   catch (Exception ex)
   {
      Exceptions.ProcessModuleLoadException(this, ex);
   }
}

/// <summary>
/// Handles the <see cref="LinkButton.Click"/> event for the <see cref="EditCode.Delete"/>
/// <see cref="LinkButton"/>.
/// </summary>
/// <param name="sender">The <see cref="Object"/> source of the event.</param>
/// <param name="e">An <see cref="EventArgs"/> that contains event data.</param>
protected void Delete_Click(object sender, EventArgs e)
{
   try
   {
      // only attempt delete if item exists
      if (!DotNetNuke.Common.Utilities.Null.IsNull(this._id))
      {
         CodeController.DeleteCode(this.ModuleId, this._id);
         //refresh cache
         this.SynchronizeModule();
         this.Response.Redirect(Globals.NavigateURL(), true);
      }
   }
   catch (Exception ex)
   {
      Exceptions.ProcessModuleLoadException(this, ex);
   }
}

Has anyone seen this? Ideas, suggestions, comments?

Thanks in advance.

I was having a similar problem.  Try changing your Response.Redirect to allow DotNetNuke to finish it's processing by:

 this.Response.Redirect(Globals.NavigateURL(), false);

If a control tries to end the current thread, which is what this.Response.Redirect(Globals.NavigateURL(), true); does, then that will cause the ThreadAbortException.
