hide parameters and block changes

[Arthur]

I'm using MVC 3, and I use Telerik Report to call a method witch the parameter is the user id, and it should not be changed, so the user wouldn't see other user data.

public List<ViewBoleto> ListBoleto(long userid)

what I did was, in the report.cs, I let the parameter as:
 new Telerik.Reporting.ObjectDataSourceParameter("userid", typeof(long), "=Parameters.userid.Value")});

so I set the value in ViewReport.aspx, and I set as Visible = false, so nobody could edit it.

rpt.ReportParameters["userid"].Value = ViewData["UserId"];
rpt.ReportParameters["userid"].Visible = false;

It works wonders, but there is a bug, when I click in Refresh, the "Navigate Back" button turns green, and if I click on it, the Parameters will turn to Visible = true, and the user can change the values!!!

Is there a better way to I call the method ListBoleto, and pass the parameter, and block the user from changing it?

here is a sample:

mirror2: http://www.crocko.com/DC177BE8D9AD498B9581512C7ACD22AC/TelerikReportTest.zip

I tried in the Telerik Reporting Q1 2012

in the TelerikReportTest folder there are 3 pictures that shows what is happening.

In the sample, there are 2 users (user 1, and user 2). When the bug happens, I can access the other user.

Hi Arthur,

We've answered your inquiry in the support ticket you've opened. Here is our reply:

We verified the unexpected behavior you've reported. For the time being you can easily resolve this by setting the ParametersAreaVisible property of the viewer to false.

Hi Steve,

I tried to set it to false in the Report1.Designer.cs file before, but I had somewhat misunderstood it, and couldn't make it work. But I got it now, and it's working great!

Thank you very much :)
