using GUID type for valuemember in reportparameter

[katja purrazzo]

Hi
I have a report with a report paramter set with the following properties

Name=myparameter
type= string
available values:
        datasource= (mybusinessobject)
      displaymember=lastname
      valuemember=ID
multivalue=true


The valuemember ID is of type System.Guid. Executing the report I get the message:
availablevalue for parameter myparamter should be of type string.invalid value.

how can I use guid??

Hi guys,

The Report Parameters Type property is used to give the report engine guidance which editor (UI) to render for the specified parameter. You can easily convert the input and output values to any type with an embedded Functions and an User Function such as the following one:

public static Guid ConvertToGUID(object guid)
{
    return new Guid(guid.ToString());
}

To convert the Guid to String for the ReportParameter.AvailableValues.DisplayMember and ValueMember properties you can use the CStr(System.Object) function that converts an expression to string value.
