SQL Reporting :: Dynamically Changing The Path / Data Source For A Reportviewer?
Nov 12, 2010
I have a reportViewer control and I dynamically setting the report path and dataset in the page load event if it is not a post back. This first report displays without issue. However, when I attempt to change the report path / dataset via the onChange event from a dropdown list I get the following error:
A data source instance has not been supplied for the data source "Summary_DataTable1".
This code works fine and the summary report is displayed the first time the page is loaded.

I have a simple web form with a dropdownlist and a ReportViewer. I would like to dynamically change the report within the viewer when the user makes a selection in the dropdownlist. I think I need to alter the ObjectDataSource that the ReportViewer is using. I've tried a few things without success.

I'm venturing into the world of Microsoft Reporting Services for the first time. So far it's gone pretty well, but I do have a couple of questions. The biggest one is, can I get the ReportViewer to use a relative path to my .rdlc file instead of the full path name that it seems insistent on using? When I'm developing locally oh my desktop, my filepath is c:inetputwwwrootcascadewritingwritingresults.rdlc; however, when I move this to production the filepath will become :websitecascadewritingwritingresults.rdlc. The .aspx page that my ReportViewer is embedded in resides in the same directory as the .rdlc file itself, so I was hoping I could just simply chop off the path altogether and reference the file name, but when I do ReportViewer fusses at me and says it can't find the file.
An error occurred during local report processing.
The report definition for report 'c:inetpubwwwrootCascadeWritingResults.rdlc' has not been specified
Could not find file 'c:inetpubwwwrootCascadeWritingResults.rdlc'.
In case you need/want to see it, my code for the ReportViewer is below:

I have a vb.net web site. Currently it is generating reports via ReportViewer. The datasouce for the all reports is set at the deploying of the report.
ReportViewer is configured in the aspx page
<rsweb:ReportViewer ID="myReportViewer" runat="server" ShowParameterPrompts="true"
ZoomMode="Percent" Height="1100px" Width="1000px" BorderWidth="1">
</rsweb:ReportViewer>
I am setting up the ReportViewer using the following code.
Dim _cred As New ReportServerCredentials(Session("_ApplUser"), Session("_ApplPswd"), Session("_ApplDom"))
'Set the processing mode for the ReportViewer to Remote
myReportViewer.ZoomPercent = 100
myReportViewer.Width = Unit.Percentage(100)
myReportViewer.Height = Unit.Percentage(100)
myReportViewer.ProcessingMode = ProcessingMode.Remote
Dim _SrvRpt As ServerReport
_SrvRpt = myReportViewer.ServerReport
_SrvRpt.ReportServerCredentials = _cred
'Set the report server URL and report path
_SrvRpt.ReportServerUrl = New Uri(Session("_RSConn"))
_SrvRpt.ReportPath = Session("_RSFold") + _rr.Report_Path
myReportViewer.ServerReport.Refresh()
lblTitle.Text = _rr.Report_Title
myReportViewer.ServerReport.Refresh()
myReportViewer.Visible = True
What I want to do is dynamically set the datasource for a report at runtime. That is, I have 2 datasources already configured in my Report Manager. I want to have the vb.net pick which datasource based on a enviornment variable. So, if Env 1, then use Datasource 1 in the Report Manager. Of Env 2 then use Datasource 2 in the Report Manager. I have seen what looks like software for doing this Locally but no for Remote.

I think I'm getting mad here...I thought this should be super simple, but I just can't figure out how to do that.This is what I'm trying to do:I want to create an rdlc report using the ReportViewer control in ASP.NET 4 (VS 2010), and, as its datasource, use a class with some properties.I tried everything I can think of, but I just can't figure this out. All the docs I found state that the object should appear in the DataSource pane of the website, but I can't make it appear there.I would like the fields of the class to appear in the report desiger so I can use them - but I can't do that either.Using the designer, I can only define new dataset - I don't want to use dataset, but business objects!So - how can I do that? Do I have to use some kind of DataSource control? How can I make the report designer know about the business object?

I recently started using SSRS 2010 and I didnt come across this issue in 2005 or 2008 versions of reporting services.
I have a report that drills down to child report1 and then that drills down to child report 2 but clicking a field in the report.
When I click on the link on the first report to go to the second report. I get this error message
"A data source instance has no tbeen supplied for the data source ''reprort2dataset"
I am not sure how to handle this error.
All reports run fine stand alone, but when I try to link them up I get that error.
I have a report viewer running the reports in an aspx page.

I have a reportviewer (Microsoft.ReportViewer.WebForms) control on my page. All my reports use one data source. I want to be able to let my reports run on a different database when started from my UAT enviroment. So the location of the reports is the same, but the data comes from a different db. I cannot seem to find how this is done, is it even possible?
EDIT: They are server reports on SQL Server . I know you can set the dataset programmaticaly but I just want the reports to point to a different db and leave the rest of the report intact.

this is the first time I have tried this so I am probably missing something that is staring me right in the face.
I have an ASP.NET page where the user fills in a request which then emails a PDF rendered from a ReportViewer instance.
It all works fine when I run it locally through the ASP.NET localhost but when I try and run it of the webserver it fails with the following message:
An error has occurred during report processing.Cannot create a connection to data source 'DataSource1'.
I can preview the report via the web based report manager via http://servername/reports which works without any problem and using the report editor in VS2005.
I suspect it is something to do with the credentials but I am at a loss. The data source is set with a username and password but this is saved within the datasource.

I have a ReportViewer control on an ASP.Net page and an RDLC set up that uses a TableAdapter that pulls one record. This works fine.I'd like to have the *same* RDLC use a different TableAdapter (schema of table is the exact same, but may have multiple records). I've tried putting two DataSets in my RDLC and having the code dynamically select which one to use, but it's not working quite right for me.

I have a data object where one of the properties is a collection of another data object. I never really figured out how to map this to a GridView, but I came up with a workaround. Now I am stuck and cannot figure out any way to do this in a ReportViewer.
Here is how I solved the GridView issue:
Say we have these objects:
public class BoysWithToys : List<BoyWithToy>
{
}
public class BoyWithToy
{
string FirstName { get; set; }
string LastName { get; set; }
int BoyNumber { get; set; }
List<Toy> FavoriteToys { get; set; }
}
public class Toy
{
int BoyNumber { get; set; }
string Toy { get; set; }
}
What I wanted to do was to map BoysWithToys to the GridView and present one GridView row per BoyWithToy record. Where there was more than one FavoriteToys record I wanted to list them in a bulleted list in the FavoriteToys column. I accomplished this by calling RowDataBound() for the GridView, casting the e.Row.DataItem to BoyWithToy, then looping through all of the FavoriteToys and adding each Toy to a bulleted list, then setting the column's text to that list.
I have no idea how to accomplish anything similar in ReportViewer. If I simply drag the BoysWithToys DataSource to the designer and run it, the FavoriteToys column shows '#Error'.

I'm working on a local report that has two ObjectDataSource objects. When trying to bring up the report from an ASP.NET page using the ReportViewer control, the report goes out to the first ODS and gets its data just fine but when it calls out to the second ODS to get that data the HttpContext.Current property is null. We're using InProc sessions and the worker process count is set to 1. Has anyone else bumped into this one?

I'm stumped after a few days of searching and trying to create a Data Source to Oracle for a report under Visual Studio 2005. I followed the guide at
[URL]
I am able to connect through the Server Explorer to our Oracle database using both .NET Framwork Data Provider for Oracle and Oracle Data Provider for .NET. I can execute queries on both of these and retrieve data.
The problems start when I try to create a data source under the Solution Explorer. I have created a Business Intelligence project on my local computer.
Data Source Wizard Select Create a data source based on an existing or new connection. Click New... Here the Provider is disabled and it appears defaulted to SqlClient Data Provider. All I can do is connect to a MSSQL server.
How can I connect to an Oracle database here?

I can successfully run a sample report on the local computer. DataSource and Report are valid it renders perfect.
But when i move my DataSource and Report to Remote server which is hosted by a company, then i always receive following error!. It is really disgusting.
An error occurred during client rendering.
An error has occurred during report processing.
Cannot create a connection to data source 'DataSource1'.
For more information about this error navigate to the report server on the local server machine, or enable remote errors

I'm working on a site where we want to include a pie chart on a page. Right now I'm working on implementing that through Reporting Services (RDLC file) with an object data source.The SelectMethod of my object data source is a method that returns a list of business objects; lets say a List<Alpha> and Alpha has a sub object Beta with a Name property. In my report definition I have set the Category groups to be: =Fields!Beta.Value.Name this means that Alpha.Beta.Name are my pie slices. I got the following error:
An error has occurred during report processing. The Group expression for the rouping 'chart1_CategoryGroup1' contains an error: Object variable or With block variable not set.I was able to confirm this is because Beta is nullable and was able to fix the issue by updating the object Alpha to return a new Beta() if the Beta property is null. This solution is not ideal though because there are other places in my code where I need Beta to be null if it doesn't have a value yet.Is there a way to update the report definition to accept a null property as valid? Ideally I would like to specify the value as "Not Set" if Beta is null.

I have an SSRS report that has a Comments field where there's enough text to span multiple rows per record. It renders fine in the ASP.Net ReportViewer control, but when it's exported the formatting can be different. Exporting to Word it looks fantastic. But exporting to Excel and PDF, the row height for each record is never increased beyond the default, so the text just gets truncated. In Excel I can go in and double-click on individual or multiple row heights to fix them, but this is an extra step we don't want.

I have upgraded web application from VS.2008 to vs 2010. I was using previously ReportViewer 2008 control in a page and replaced with 2010 ReportViewer Control.
I have installed the ReportViewer Redistributable also in my local pc as well as in the server. Also as per the new requirement I have placed the Scriptmanager in the web page where the reportviewer control located.
While running the page, the reportviewer run the report and is not showing the data on the screen. It shows the blank screen. But If I export the data to execl or world it is showing the data. Also the page numbers in the reportviewer showing the total pages available in the navigation bar. I am sure the report is running and bringing the data to the screen but not showing it.

For many of the pages I build, I don't wish to have the ReportViewer visible until firing an event such as a button click. Using .Net 4.0 and ReportViewer10, however, throws the error "Message: Sys.ArgumentNullException: Value cannot be null. Parameter name: panelsCreated[1]" if you try to keep a panel containing the ReportViewer hidden until after a button click.Since I couldn't find much about this topic online, I'd basically been working around this for some time until I figured out today that if you reset the ReportViewer ReportPath in the code behind in the button click (even if it's the same path as in the aspx page), you can successfully keep the ReportViewer hidden until the button click.

I have created many reports in my ASP.Net 3.5 app's and using VB Code-behind. I have the following code that will take the report from the reportviewer and on a click of a button, export it to PDF. So now, I can hide the reportviewer and just have the button click events generate my PDF's. I do not know how to tweak this code to enable me to print directly from another button's click event without the reportviewer being visible.
