PROBLEM
How to use a Guid as value for report parameter or data source parameter?

SOLUTION
Set the Type of the ReportParameter to String. Use the CStr(System.Object) built-in conversion function to convert the Guid to String for the ValueMember property of the report parameter AvailableValues.
When using Guid DataSourceParameter and its value is set to a ReportParameter, create an User Function to handle the conversion:
C#
public static Guid ConvertToGuid(string guid)
{
           return new Guid(guid);
}

VB.NET
Public Shared Function ConvertToGuid(guid As String) As Guid
    Return New Guid(guid)
End Function

and set the value for the DataSourceParameter:

= ConvertToGuid(Parameters.Parameter1.Value)



OTHER APPROACH

Convert the Guid value to a String value in the data-retrieval method, or add a calculated field to the data source component by using the CStr(System.Object) built-in conversion function to convert the Guid to String.
Then you can use String report parameters directly.
