The Hidden expression for the tablix ‘Details9’ contains an error

Question

User-1782670433 posted

Hi,

I am getting the following error when the report viewer loads. It only occurs if I use the expression below to hide a table row if there is no value. Any Ideas?

• The Hidden expression for the tablix ‘Details9’ contains an error: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

NM found a solution

 

 Protected Sub ReportViewer1_Load(sender As Object, e As System.EventArgs) Handles ReportViewer1.Load

        ReportViewer1.LocalReport.SetBasePermissionsForSandboxAppDomain(New PermissionSet(PermissionState.Unrestricted))
    End Sub
