Hiding Parameter Prompts

Hello everyone,

I have a request to hide certain parameters in a report based on the current user logged into our web based report viewer using the ReportViewer control fo asp.net.

I am doing the standard stuff required to display the report as shown below.




Code Snippet
rptViewer.ServerReport.ReportServerUrl = new Uri("http://172.17.144.26/ReportServer"); // new Uri(MINETSecurity.WebSettings.WebServerPath, UriKind.Absolute);
rptViewer.ServerReport.ReportPath = ReportName;
rptViewer.ServerReport.DisplayName = "Report1";
rptViewer.ServerReport.ReportServerCredentials = new CustomReportCredentials("myUsername", "myPassword", "myDomain");






Now that i have loaded the report into the viewer i illiterate through the report parameters looking for the ones which the specified user should not see as show below.




Code Snippet
ReportParameterInfoCollection MyReportParams = rptViewer.ServerReport.GetParameters();
foreach (ReportParameterInfo MyParameter in MyReportParams)
{
// returns a value from a custom class which is a predefined value for this user based on the current user logged into the website
string Value = CustomParameterValues.ToString(GlobalUserSettings.CurrentUser.CustomValueList);
if(Value != "") MyParameter.PromptUser = false;
}



Here is where the promblem lies, when i try to set the value of PromptUser i get the following compiler error.

Property or indexer 'Microsoft.Reporting.WebForms.ReportParameterInfo.PromptUser' cannot be assigned to -- its is read only

Is there anything i can do to set certain parameters invisible to the user and set there value myself. I know i could create 2 seperate reports and set the PromptUser value in the designer but i dont really want to be duplicating reports just to hide or show parameters.

I have tried using the SetParameters method of the ReportViewer component to pass the value of the parameters that should be hidden and even set the visible property to false, but it dosn't seem to work.

Any help here would be appreciated.

Cheers
