  • User-309799621 posted


    I am using VS 2008 and SQL 2008,.I am trying to build a report using Report viewer using Parameters.I am completly new to this concept,so i was trying to develop using the basic steps as shown in various tutrials.

    1> connect to dataset

    2- Configure server

    3 - table Adapter

    4 - Add new report

    5 - Drag a table in the Report screen and add the columns

    6 *  Here i am adding parameters ( fromdate,todate).Please tell me what mistake i am doing

    I got to Reports -> ReportParamaters -> Add new Parameter - > fromdate -> type : Datetime. (Same for Todate)

    7 - > In the web page. Added 2 textboxes and a button

    8 - > Dragged Reportviewer - > choose Datasoure and Report name

    Now the code Behind.

    On button click

    Protected Sub btnView_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnView.Click
            Catch ex As Exception

            End Try
        End Sub

     Private Sub setReportParameters()
            Dim Fromdate As New ReportParameter("Fromdate", tbFromDate.Text)
            Dim Todate As New ReportParameter("Todate", tbtodate.Text)

            Me.ReportViewer1.LocalReport.SetParameters(New ReportParameter() {Fromdate, Todate})

        End Sub

    When i Run the Report I get this Following Error


    • An error occurred during local report processing.
      • Error during processing of ‘FromDate’ report parameter.

    All i can see is the textboxes and Button.When i click on it,nothing happens...

    Pleaseeeeeeeeeeeeee help..

    Remove step 7 ..... That will be created by the reportviewer. And remove all the code behind Set the Datasource and report path from the viewer's smart tag

    just try to remove the setReportParameters() method in your View Button call and check whether report works by directly typing from date and to date.

    I think may be its a datetime issue. can you please run the report the way as i said and then confirm?

    Hii Ashutosh,

    I did the same way u told me to..but still the same error repeats.When i load the page..

    An error occurred during local report processing.
    Error during processing of ‘FromDate’ report parameter.

    When i click on Run Report button it says

    An unexpected error occurred in Report Processing.
    Object reference not set to an instance of an object.

    I also want to mention When i add Parameters,in the Report design. Report Parameters -> Add Parameters -> In the available values -> i have added the Expression - > =Parameters!FromDate.Value(0)


    Is this correct?

    So..When i  made the change i got the Build Error

    "Error    2     The report parameter ‘FromDate’ has a DefaultValue or a ValidValue that depends on the report parameter “FromDate”. Forward dependencies are not valid.
