Is there a way to disable levels of a cascading dynamic parameter?

Question

Hello,
As the title describes, I'd like to see if there's a way of programmatically disabling levels of a cascading dynamic parameter.
For example, I have a dynamic cascading parameter that has two levels, levelA -> levelB, where based on the value of levelA, levelB choices get filtered. I'd like to programmatically populate a value for levelA and disable it so that the user can't change it.
Miscellaneous info:
Language: C#,
IDE: Visual Studio 2010
CR for Visual Studio ver: 3.0.2.x
Any help is appreciated.
Thanks.

Hi Andrew,
First, the version of CR for VS does not make sense, did you mean 13.0.2000.0? If so that is the Assembly version which never changes. The real version s the version of the dll's. Or you can query the GAC for the version this way:
foreach (Assembly MyVerison in AppDomain.CurrentDomain.GetAssemblies())
    if (MyVerison.FullName.Substring(0, 38) == "CrystalDecisions.CrystalReports.Engine")
        //File:             C:\Windows\assembly\GAC_MSIL\CrystalDecisions.CrystalReports.Engine\13.0.2000.0__692fbea5521e1304\CrystalDecisions.CrystalReports.Engine.dll
        //InternalName:     Crystal Reports
        //OriginalFilename:
        //FileVersion:      13.0.9.1312
        //FileDescription:  Crystal Reports
        //Product:          SBOP Crystal Reports
        //ProductVersion:   13.0.9.1312
        //Debug:            False
        //Patched:          False
        //PreRelease:       False
        //PrivateBuild:     False
        //SpecialBuild:     False
        //Language:         English (United States)
        System.Diagnostics.FileVersionInfo fileVersionInfo = System.Diagnostics.FileVersionInfo.GetVersionInfo(MyVerison.Location);
        txtRuntimeVersion.Text += fileVersionInfo.FileVersion.ToString();
        // check if CrsytalDecisions.Enterprise dll's can be loaded ( Anything but Cortez - managed reporting )
        if (fileVersionInfo.FileVersion.Substring(0, 2) == "13")
            btnRasOpen.Enabled = false;
        CRVer = fileVersionInfo.FileVersion.Substring(0, 2);
        return;
As for the dynamic parameter you cannot get the top levels of the prompt, only the last field info but there are limitations right now.
If you look at the Query all you will see is the last prompt field in the SQL.
Currently we have an Enhancement request to be able to get the field name from the the report to get that last field name. There is no plans to get the field names above though so no option to disable in code.
What you can do though is change the Dynamic parameter to Static and/or List of Values and then you can change the behaviour in your app by creating your own Parameter Prompt UI and the result should be noted in the WHERE portion of the SQL Statement. And no you cannot modify the SQL statement.
