buscando en el internet me encontre este codigo, pero lamentablemente para mi no se como transcribirlo, he intentado una y otra ves pero sin resultados.

Si alguien me Hace el Favor se lo voy a agradecer muchisimo.

To Modify Parameter Fields at Runtime
[Visual Basic] 
' Declare variables needed to pass the parameters
' to the viewer control.
Dim paramFields As New ParameterFields()
Dim paramField As New ParameterField()
Dim discreteVal As New ParameterDiscreteValue()
Dim rangeVal As New ParameterRangeValue()

' The first parameter is a discrete parameter with multiple values.

' Set the name of the parameter field, this must match a 
' parameter in the report.
paramField.ParameterFieldName = "Customer Name"

' Set the first discrete value and pass it to the parameter
discreteVal.Value = "AIC Childrens"
paramField.CurrentValues.Add(discreteVal)

' Set the second discrete value and pass it to the parameter.
' The discreteVal variable is set to new so the previous settings
' will not be overwritten.
discreteVal = New ParameterDiscreteValue()
discreteVal.Value = "Aruba Sport"
paramField.CurrentValues.Add(discreteVal)

' Add the parameter to the parameter fields collection.
paramFields.Add(paramField)

' The second parameter is a range value. The paramField variable
' is set to new so the previous settings will not be overwritten.
paramField = New ParameterField()

' Set the name of the parameter field, this must match a
' parameter in the report.
paramField.ParameterFieldName = "Customer ID"

' Set the start and end values of the range and pass it to the 'parameter.
rangeVal.StartValue = 42
rangeVal.EndValue = 72
paramField.CurrentValues.Add(rangeVal)

' Add the second parameter to the parameter fields collection.
paramFields.Add(paramField)

' Set the parameter fields collection into the viewer control.
crystalReportViewer1.ParameterFieldInfo = paramFields

crystalReportViewer1.ReportSource = "c:\reports\my report.rpt"

En Realidad todo el Codigo no me interesa me interesa la parte donde se envia el rango de valores.

' Set the start and end values of the range and pass it to the 'parameter.
rangeVal.StartValue = 42
rangeVal.EndValue = 72
paramField.CurrentValues.Add(rangeVal)

Bueno Mientras tanto seguire Intentando.


Saludos y mil gracias...
