Hi,

Glad to hear that you have found the solution to your question.

Please let me know if you have further questions.

My application is in VB.Net (windows desktop).  All the examples were for web programming which I haven't gotten into.  I did try the on-line documentation and, in frustration, gave feedback.  I was rewarded with the information that I needed:

You can handle the Form.Load event and set the parameter values by using UltraReportViewer.Parameters.Add() method.  You will need to pass in a Parameter object that has its ParameterName and ParameterValue properties already set.

The following subroutine works for my needs.  I can call it anytime I need to change the values of the parameters for this report. 

    Private Sub ChangeParameters()

        Try

            Dim PRptDwgNo As New Infragistics.Win.UltraWinReportViewer.Parameter

            Dim PRptDwgRev As New Infragistics.Win.UltraWinReportViewer.Parameter

            If strParameter.Length = 2 Then

                Me.UltraReportViewer1.Parameters.Clear()

                PRptDwgNo.ParameterName = "PDwgNo"

                PRptDwgRev.ParameterName = "PDwgRev"

                PRptDwgNo.ParameterValue = strParameter(0)

                PRptDwgRev.ParameterValue = strParameter(1)

                Me.UltraReportViewer1.Parameters.Add(PRptDwgNo)

                Me.UltraReportViewer1.Parameters.Add(PRptDwgRev)

                Me.UltraReportViewer1.RefreshReport()

            End If

        Catch ex As Exception

            MsgBox("Change Parameters" & vbCrLf & ex.Message)

        End Try

    End Sub

Thanks
