Showing Classes And Structs In ReportViewer
Nov 22, 2006
I show business objects in the ReportViewer as it is described in the MSDN article [1]. In the article they only use intrinsic types like int and string as properties of the business object.
My business objects contains also structs and classes (e.g. Point) as Properties. I expected the Reporting Services to call the ToString() method if it is not an intrinsic type. But it only shows the error string "#Error" in the TextBox.
How can I show a Struct property of my business object as a report value?

I am trying to use VB.NET to run SSIS packages. However I don't have the various dts namespaces available. When I attempt to import them I only have Microsoft.SqlServer.Server in intellisense.
I am running on XP sp2, VS 2005 (full install) and even went so far as to install sql 2005 sp1 full install on my local machine.
What gives with only having Microsoft.SqlServer.Server available?
thanks,
Scott

As you all know, in Framework 2.0 on the desktop platform you have the convenient "abstract" Db* classes that can be used to write more generic code. For instance System.Data.SqlClient.SqlConnection inherits from System.Data.Common.DbConnection, and so forth. Now the docs clearly say that this applies to the corresponding classes in the Compact Framework. And i have seen this implied by other web searchs I've done. However this does not seem to be the case -- or, I'm missing something somewhere.
The following simple code on the desktop platform compiles OK:
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
DbConnection conn = new SqlConnection();
However it doesn't compile in a compact framework project: "Cannot implicitly convert type 'System.Data.SqlClient.SqlConnection' to 'System.Data.Common.DbConnection'".
Reflector also indicates that the Compact Framework class doesn't inherit from DbConnection.
OK, so am I missing something here, or what was the reason that Microsoft did it differently??

Anyone have a recommendation on SSIS classes (providers and instructors)? It looks like Brian Knight's classes must be at the top of the list. His classes are always full!

I have a report which has an embedded image in the heading and an image control that loads images from the database (Image control Data section configured as MIMEType=image/jpg, Source=Database, Value=Fields!Img_Data.Value).
In both cases I can see the embedded heading image and the database images in design mode (VS2005) and through the report manager web pages. When I try to render the report through the ReportViewer web control in my web application, the images do not display (standard missing image red "X" appears).
I have a button on my web form which re-runs the report and exports it to PDF, and when pressed the report is displayed correctly in PDF with all images.
What do I need to do to the ReportViewer web control for it to show embedded and database images? I am using the ReportViewer for 2005.
Please advise of give me some place to look.

I'm still trying to transition from a DB-centric view to an OO view,
and I could use some help from any of you OO-design wizards out there. A very common db representation is Table A, Table B, and Table A_B, which maps the two in a one-to-many relation. E.g., create table Companies ( companyId int, name varchar ); create table Products ( productId int, name varchar ); create table Companies_Products ( companyId int, productId int ); So how does this translate into object-land? I started with: public class Product public id as integer public name as string end class public clas Company public id as integer public name as string public products as generic.list(of Product) end class OK,
so far, so good -- I've represented most of my data. But I've lost some
important information: given a Product object, I have no easy way to
find out which company sells it. SQL: scan the Companies_Products table OO: iterate through companies, nested iteration through company.products. Do I just add a function to my data access layer that does the lookup? Is that allowed? On
a side note: can anyone recommend a good intro to OO design
specifically for database programmers? It seems like most of my
confusion comes from issues of translating tables into classes. Thanks!

I work on the Clinical Surgery Department Data Application.
The patient gets through the Admission, Surgery, PostSurgery and Discharge stages during his staying in the department. The Doctors just insert their medical data in to the different tables. I have three main classes: User, Patient and Portfolio ( patients portfolio ) and all the business bases on these classes.
The problem is with the Classes per Medical Data Tables. The Medical tables should exist cause it includes the medical data about the patient however what is not clear: Whether I should create Business and Entity classes per each medical data table ( and this is something like 50 tables ) or I should insert all the functions in the Portfolio class and then there will be a mess of functions in one class? What is the accepted way to perform it ?

All --
Please help.
I need to know how to refresh Linq-To-SQL classes after schema changes without dropping and adding them.
Now, when I make a schema change (such as add or delete a column to a table), I want to "refresh" the Context.dbml file.
The only way that seems to work is to drop the table from the Context.dbml designer and then add it back in.
Is there a better way to do this?
How are others doing this?
Please advise.
Thank you.

Hi,
Hopefully someone out there will be able to help me with this question. I'm trying to setup my C# program to use the Backup and Restore classes to perform backups and restores on an SQL Express 2005 database.
From the documentation I've read... it seems that when you go to restore the database, it's a good idea to backup the current transaction log. But when I do this using the Backup.SqlBackup method I get an error saying that no database backup is detected so a log backup can't occur. I'm not sure if this has something to do with the fact that I moved my backup files from the default SQL Express/Server Backup folder to a different location. Shouldn't it know I've already performed a backup though?
And does anyone know how to set a parameter to backup to a different file location than the default? I've been doing a backup then a file move. Works the same, but it would be nice to have everything together in the Backup object.
Thanks!

Hi all,
I'm creating a custom interface for reporting services but I am having a few problems. This is my environment:
Using the ReportViewer component in remote mode to show my reports of the report server. There are 2 user levels of which any user can be apart of, Admin & user. In every report, there is a parameter called MERCHANTID, when the user who logs in (via custom login interface) is of group admin, then the merchantid parameter gets prompted before the report is run, if the group of the user is "user" then the merchantid parameter is hidden, and is passed programatically to the report. The report path also
My Questions:
1. When my reportviewer component loads up the report and prompts for a parameter, when you select a parameter value or type it in, it just posts back with no results, just the parameter prompt again with no data... How can this be corrected?
2. How do I pass report parameters programatically... so that when my user id of group "user" then "merchantid" gets passed automatically, but if there is any more parameters, then that gets prompted...
Thanks for your help.

I have read a million documents on this question and I still don't get it. I would greatly appreciate any insights.
I start a new WebSite. I put these specs in web.config:
<authentication mode="Windows"/>
<identity impersonate="true" userName="AIBablh" password="blah" />
<authorization> <deny users="?"/> </authorization>
I put a ReportViewer control on my only page.
I set the URL and the ReportName and run the application which returns HTTP 401, authorization error. What else do I have to do to make this little demonstration work?
I have read entries about credentials, about delegation, about application pools, about just about everything.
Isn't this just supposed to work? This works without difficulty on a Windows form.
Much thanks.

Hi,
I am trying to develop a custom web page to display and generate our company reports.
It shoud have a login page, and then a general window with 2 or 3 frames (top frame with general info, left frame with a
dynamic list of all existing reports (eventually categorized by a certain word in the report title), and a center frame
that has initialy the company logo and after selecting a specific report displays the parameters and afterwards the
generated report).
Does anybody has some pointers or links on the web where some of this is a little bit documented.
I have dev skills in vb.net and know how to work with ssrs.
My web dev skills are intermediate.
All info, tips, hints are very welcome ...
Greetings

I have a report in which I am trying to get a parameter to be displayed in a textbox. I have declared a parameter in my .rdlc called UserName and the expression in the textbox is as follows...
=Parameters!UserName.Value
With that said, I have code in the window containing my ReportViewer to set the parameters and run my report as shown below...
string UserName = "test";
List<ReportParameter> paramList = new List<ReportParameter>();
paramList.Add(new ReportParameter(UserName));
this.baseReportViewer.LocalReport.SetParameters(paramList);
this.baseReportViewer.RefreshReport();
With these things in mind, can anyone here provide me with a reason as to why my report on comes up with a message stating "An error occurred during local processing. One or more parameters required to run the report have not been specified." ???
If I remove the parameter and text box and strip out the code pertaining to the paramter in my window, the report runs without error.
Any ideas?

Is there a way to make the data selecatable. For example, a user runs a report and wants to copy the applicationId onto their clipboard so they can use it to search in another application. Currently they have to remember or write down a 9 digit number. Not very user friendly...
I am currently using a data table as the container for the data in my rdl file. Then I use reportviewer for winforms to embed it in our user application.
Thanks

Hello,
I'm having problems using the ReportViewer control (which you can use in VS2005). When I go to the page that contains the control, the images (back, next, print, etc) don't show up and I get different javascript errors (one of them is the "RSClientController is undefined" error). After some investigation, I found out that the path to the Reserved.ReportViewerWebControl.axd file is incorrect (as I see it in the page source). On every place this axd file is used (for the images and the necessary javascript file), the path is "/Reserved.ReportViewerWebControl.axd?...", while it should be "/reportserver/Reserved.ReportViewerWebControl.axd?...". If I go directly to the "/reportserver/..." url, I can retrieve the images and javascript file. So, somewhere the path to the axd file is set in a wrong way.
For example:
<script src="/Reserved.ReportViewerWebControl.axd?OpType=Resource&Version=8.0.50727.42&Name=Scripts.ReportViewer.js" type="text/javascript"></script>
while this should be:
<script src="/ReportServer/Reserved.ReportViewerWebControl.axd?OpType=Resource&Version=8.0.50727.42&Name=Scripts.ReportViewer.js" type="text/javascript"></script>
I have included the ReportViewer control in a usercontrol (ascx). This usercontrol is implemented in Sharepoint using the "Son of Smartpart" webpart. I'm using SQL Reporting Services 2005 (with the database, SQL Server 2005, hosted on another server). Using the ReportManager, everything is fine.
I really need to get this working, but I'm out of ideas (I've been searching for days to solve this, but can't seem to find the correct solution).
Any ideas?

Regarding this post: http://forums.microsoft.com/TechNet/showpost.aspx?postid=2111183&siteid=17
This could be the follow up of that post, but I thought it would be a good idea to open a new post to discuss the ReportViewer.Reset() method.
This is the background:I was getting a "Execution '' not found" error when generating reports, VDeepak wrote something about ReportViewer.Reset() as a solution for this, so I tried with it.
At my workstation, running the project with VS2005 it worked flawlessly. Nevertheless, when I updated the files on the server I got an exception: "method ReportViewer.Reset() not found". Apparently, this was because of an outdated dll: Microsoft.ReportViewer.WebForms.dll. In other post, somebody told this could be solved installing the SQL Server 2005 SP1, I did it with no success... I found a SP2 was launched recently, so I downloaded installed it... Now another exception: a "http bad request exception". Desperate, I removed the ReportViewer.Reset() line from the code and uploaded the files to the server again. This time, everything went ok again, actually, I havn't found the freaking "execution '' not found" exception.
There are two questions here:
1 - What exactly does ReportViewer.Reset() method do? and why the same code could be failing on the server when it was working ok in the workstation (believe me, I tried everything, the only diference is this method).
2 - By chance, could the "Execution '' not found" error be fixed with the SP2??? I searched the change log and found nothing about it.
Thanks!

Hi,
apologies for what I know is a very basic question. We have a very simple ASP.NET page that includes a report viewer object. The site containing the page is on a public server, and the report server is on an internal server (actually the same physical machine, but running on a different IP) - we are referencing the report server via a 10.x.x.x address and it's not connecting from outside. The report server is not accessible from the public address, and I don't believe there's firewall issues - can someone please point me in the right direction?
thanks,
Steve.

Hi
Everyone. I see that Visual Studio 2005 SP1 is out and includes an updated
ReportViewer control. Is there an update to the ReportViewer
Redistributable with those same fixes? Our product installs this
redistributable silently, and we render reports locally (i.e. RDLC), so
installing the full Visual Studio service pack would not help us (and installing just the assemblies would not either, since the Redistributable install seems to do other things "under the hood."
Thanks for your help!

The report isn't shown until F5 or refresh button isn't clicked. Does anybody have problem like this one?
