NULLABLE TYPE IN DATA METHOD

[panchooo]

hi guys,

Im using a objectdatasource and after selecting my data method, and giving values to the data parameters im having problems,  an error apears while processing the report its because some of my parameters are nullable, but im not sure now what value i have to send

i tried nothing null -1  and nothing seems to work, any guesses?

Thanks for answering peter, and sorry if i didnt explain my self

i was using an object data source and when i defined the data method i used this method

      Public Shared Function SearchRejections(ByVal rejectionID As Nullable(Of Integer), ByVal defectID As Nullable(Of Integer), _

            ByVal comments As String, ByVal insertedbyID As Nullable(Of Integer), ByVal lot As String, _

            ByVal productID As Nullable(Of Integer), ByVal qaTechID As Nullable(Of Integer), ByVal quantity As Nullable(Of Integer), _

            ByVal rejectedOnStart As DateTime, ByVal rejectedOnEnd As DateTime, _

            ByVal detectedByOperator As Nullable(Of Boolean), _

            ByVal isVoided As Nullable(Of Boolean)) As List(Of Rejection)

problema was the nullable data type no matter what i send as a parameter the report would produce an error while processing, what i did was a new method

     Public Function SearchRejections2(ByVal rejectionID As Integer, ByVal defectID As Integer, _

            ByVal comments As String, ByVal insertedbyID As Integer, ByVal lot As String, _

            ByVal productID As Integer, ByVal qaTechID As Integer, ByVal quantity As Integer, _

            ByVal rejectedOnStart As DateTime, ByVal rejectedOnEnd As DateTime, _

            ByVal detectedByOperator As Integer, _

            ByVal isVoided As Integer) As List(Of Rejection)

and it worked great that way.

thanks

Hi Peter,

I've got the same issue as well. I've got a ObjectDataSouce bound to a Select method which has a nullable datetime parameter.
The parameter is mapped to a ReportParameter specified as DateTime with allow null set to true as well as allow blank.

How can I map this to my Select method? Everything I've tried so far has failed.

Hello Tomas,

We have made some tests locally with a nullable DateTime report parameter and nullable select method parameter. However we are unable to reproduce the unexpected behavior. Thus we will appreciate if you elaborate further and open support thread and send us a sample project that exhibits the issue to debug on our end.

Best wishes,
Peter

Hi,

It looks like you have to use the Objectdatasource's configure wizard instead of editing the parameters through the edit parameters dialog to correctly map nullable types.

Thanks Peter for the help.
