How to Create Report Viewer Binding to Object in VB.NET

I have Class named "User", code:

     Public Class User

        Private m_id As String
        Private m_user_name As String

        Public Sub New(ByVal id As String, ByVal name As String, ByVal pwd As String)
          m_id = id
          m_user_name = name
          m_pwd = pwd
        End Sub

        Public Property Id() As String
          Get
              Return m_id
          End Get
          Set(ByVal value As String)
              m_id = value
          End Set
        End Property

        Public Property Name() As String
          Get
              Return m_user_name
          End Get
          Set(ByVal value As String)
              m_user_name = value
          End Set
        End Property

     End Class
And I want to report all the user's information, so I also have another class named "Users", code:


     Public Class Users
           inherits List(Of User)
           Public Sub New()
                  'Query users' information from Table in Database
                  Add(New User(...)
           End Sub
     End Class

When I clicked on "Print" button, it will pop up the report. I have only one Form with Report Viewer, but I have a lot of reports using this Form with Report Viewer. so I code like this:


     Public Class Form1
            Private Sub Form1_Load(...) Handles MyBase.Load

                Dim bs As New BindingSource
                bs.DataSource= New Users
                
                Dim rpt As New Microsoft.Reporting.WinForms.ReportDataSource
                rpt.Name = "Report_User"
                rpt.Value = bs
                ReportViewer1.LocalReport.DataSources.Add(rpt)
                ReportViewer1.LocalReport.ReportEmbeddedResource = rpt.Name
                ReportViewer1.RefreshReport()
            End Sub

But it doesn't show anything... Please help me... I really need your help..
Thanks in advance

Hello all,

I've developed an application on .net Framework 3.5 with VS 2010 and now I am trying to develop it with VS 2012.

I'm facing a problem with ReportViewer.

In my application, I'm using a specific .dll that is called by several local reports (.rdlc files). I dutifully copy the .dll in the Common 7\IDE\Private Assemblies directory, but  still cannot compile solution due to error:

"Error while loading code module: ‘Development.Tools, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’. Details: Could not load file or assembly 'Development.Tools, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies."

Please help!

I allways get an error "the assembly couldn't be loaded" is it a bug or have I to copy my assembly in an another directory.

Drill through report in Report Viewer

I am getting the following error when I click on the hyperlink in report1, and it should take me to report 2

A data source instance has not been supplied for the data source 'DataSet1_Order_Details'

 I have written the following code to handle the drill through event

 

  protected void ReportViewer1_Drillthrough(object sender, DrillthroughEventArgs e)
  {
    string orderid = e.Report.GetParameters()[0].Values[0].ToString().Trim();
    ObjectDataSource2.SelectParameters["OrderID"].DefaultValue = orderid;
    DataView dv = (DataView)ObjectDataSource2.Select();
    ReportDataSource rd = new ReportDataSource("DataSet1_Order_Details", orderid);
    rd.Value = dv;
    ReportViewer1.LocalReport.DataSources[0] = rd;
    ReportViewer1.DataBind();
  }

 Can you tell me where I am going wrong? I have a report parameter OrderID in the Report2. In the getdata method for the tabledapter for orderid I take the paramter. I am passing the paramter to the objectdatasource2 which I belive is for the getdata method of report2.

But still, it doesn't work!

Show Data-bound table in Page Header

Hello,

my situation is that I want to print a (same) table (which gets data from a dataset) on every page of a report. The table is on top of the page and followed by 4 charts per page. 

Unfortunately it is not possible to place data-bound controls (like tablix) into the page header-area. Here [http://msdn.microsoft.com/en-us/library/ms252093(VS.80).aspx ] I found this message:

You cannot add data-bound fields or images directly to a header or footer. However, you can write an expression that indirectly references a data-bound field or image that you want to use in a header or footer.

Has anyone done this? I tried to place textboxes in the body of the report, hide them, and show the value (via expression) in a textbox in the page header. That works. But with a table that has an infinite number of rows I have no successful solution.

Thank you.

What's wrong with this expression?

Hi,

One of the columns in my report contains the following value expression:

=IIF(System.Decimal.Compare(Fields!BalanceAmount.Value, System.Decimal.Parse("0.0M")) < 0,  string.Format("{0:N2}", Math.Abs(Fields!BalanceAmount.Value)) & " DR.", IIF(System.Decimal.Compare(Fields!BalanceAmount.Value, System.Decimal.Parse("0.0M")) > 0, string.Format("{0:N2}",  Fields!BalanceAmount.Value) & " CR.", "0.00"))

On running the report, the column however shows the value "#Error" in all the rows, and a following warning is written out on the Output window of Visual Studio:

Warning: The Value expression for the textrun ‘BalanceAmount.Paragraphs[0].TextRuns[0]’ contains an error: Input string was not in a correct format. (rsRuntimeErrorInExpression)

Could someone tell me what is wrong with the expression as the project compiles without any error? Also, is it allowed to insert a manual line break in the expression to make it more readable? Finally, I don't seem to find the good documentation for the report viewer.

Thanks in advance.

I have just installed VS 2005 RC.

Tried using the LocalReport control using the exact sample code provided in the help for the Render method.

I keep getting an error during the LocalReport.Render method call - InnerException = "A data source instance has not been supplied for the data source". The dataset and table supplied is valid as it works with the Reportviewer control.

Is there something I am missing or is the sample code wrong?

508 Compliance using ReportViewer and .rdlc

Hello,

I'm new to using .rdlc files and the ReportViewer control.  We have been tasked by our customer with a new requirement of making our web apps 508 compliant (things like using "alt" tags in the rendered html, etc.).  I've used a tool, AccVerify, to validated some reports as rendered in a browser and fail quite easily.  The biggest problem areas are any of the Menu and Paramter controls, which are automatically rendered from the design time property settings.

The problem is that .rdlc files are basically xml, so is there a way to update the xml files to include our own custom tags that are required for the 508?

Is there any other info available on how well ReportViewer and .rdlc files handle 508 compiance issues?

Report Viewer Control Not Exporting Properly through Cisco VPN Gateway

December 4, 2012, 2:14 pm

I have a web page that uses the reportviewer control to display reports from a remote SSRS server. It is access through an HTTPS Cisco VPN gateway for security.

I have no trouble displaying the reports , and they seem to function fine, but the toolbar is missing Icons, and the export function uses the wrong URL to try to export - which causes a 404 error.

For Example, the Url to the report Page is:

SampleUrl.com/cvpn/wpFIPiL-2fGCePezuG28P_cLZg/bahn/Interfaces/AdminReports.aspx?ReportName=CLR

This works fine, but when I try to export the report, it uses the URL:

SampleUrl.com/BAHN/Reserved.ReportViewerWebControl.axd?ReportSession=f5vcte45kbsny3rcbydo34m3&Culture=1033&CultureOverrides=True&UICulture=1033&UICultureOverrides=True&ReportStack=1&ControlID=78d4463cc8bd4cab8c99265c1bdc227f&OpType=Export&FileName=CallLogReport&ContentDisposition=OnlyHtmlInline&Format=PDF

-- It leaves out the cvpn/wpFIPiL-2fGCePezuG28P_cLZg section of the URL, and gets a 404 error.

If I manually add that section back into the URL, it gives me the export as normal.

Is there anyway to get the export working uring the proper URL?

Any help would be appreciated.

Report1 (Master Report)

Report2 (SubReport)

I added parameters to the reports. then I dropped a subreport control on the report1. and set its properties to reference to Report2.

I also set the parameter for the subreport.

But it gave me the error

Hi All,

            I have Visual Studio 2010, and .net framework 4.0 installed on my development machine.    I also have SQL Server 2008 installed (which you indicate above does not affect the issue).

           When I create a new Report project in Visual Studio 2010, the RDLC file has a reference inside it to .../2008/01/.... that looks like this:

<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">

I have tried this several times.  I have only built "loca" reports.  When I build on my local machine, the reports build and run just dandy.   But when I try to build them on our build server, running MSBUILD, the  build fails with:

the report definition has an invalid target namespace 'http://schemas.microsoft.sqlserver.reporting/2008/01/reportdefinition' which cannot be upgraded".

Im not sure why the new report didn't get created as /2010/, since everything I believe is using .net framework 4.0.       Any help greatly appreciated.

Regards,

Mike

Hi all, I have a Report Viewer that I am supplying a SQL statement with a LIKE statement in it, I am passing two parameters to it from another web page.  Everything works fine on it until I pass it the '%' wildcard...  when I run the SQL statement in SQL it runs fine and returns what I want, but not in the report.  If I pass it specific values then the report runs perfect, but for some reason it doesn't seem to like the wildcard??  Been trying to get this to work for a day now, but no luck...

Thanks for any help!!
