How do I make this code more readable?

Question

I wrote this today and I'm ashamed. What do I need to do to make this chaotic stuff more accurate and readable amongst others?

switch ((RequestReportsCalculatingStoredProcedures.RequestReportStoredProcedureType)Enum.Parse(typeof(RequestReportsCalculatingStoredProcedures.RequestReportStoredProcedureType), ihdType.Value))
    {
            //REF:This can (but should it?) be refactored through strategy pattern
        case RequestReportsCalculatingStoredProcedures.RequestReportStoredProcedureType.ReportPlanWithEffects:
            grvEconomicCriteria.DataSource = RequestReportsCalculatingStoredProcedures.ReportsDataParser(
                            RequestReportsCalculatingStoredProcedures.ReportPlanWithEffects(requestNo, RequestReportsCalculatingStoredProcedures.GetAlgorithmNoByRequestNo(requestNo)));
            break;
        case RequestReportsCalculatingStoredProcedures.RequestReportStoredProcedureType.ReportPlanWithEffectsForFacts:
            DateTime factDate;
            try
            {
                factDate = Convert.ToDateTime(ihdDate.Value);
            }
            catch(FormatException)
            {
                grvEconomicCriteria.DataSource = RequestReportsCalculatingStoredProcedures.ReportsDataParser(
                            RequestReportsCalculatingStoredProcedures.ReportPlanWithEffectsForFacts(requestNo, RequestReportsCalculatingStoredProcedures.GetAlgorithmNoByRequestNo(requestNo), DateTime.MinValue));
                break;
            }
            grvEconomicCriteria.DataSource = RequestReportsCalculatingStoredProcedures.ReportsDataParser(
                            RequestReportsCalculatingStoredProcedures.ReportPlanWithEffectsForFacts(requestNo, RequestReportsCalculatingStoredProcedures.GetAlgorithmNoByRequestNo(requestNo), factDate));
            break;
        default:
            break;
    }

You can always use an alias for the very long type RequestReportsCalculatingStoredProcedures:

using RRCSP = RequestReportsCalculatingStoredProcedures;

Note: You will need to use the fully qualified name (including namespace) in the using directive.
