Accessing Datasets / Field Collections Through Custom Code
Jun 12, 2007
Hi,
My report has multiple datasets, and I want to access the fields of a particular dataset from custom code. The problem is that the name of the dataset to use is only calculated during the execution of the custom code.
Allow me to illustrate:
public function Test(data as DataSets, fieldName as string)dim datasetName as string = CalculateDatasetName()dim ds as Dataset = data(datasetName)' now here I want to get the fieldName out of the dataset.' in the report, I would do something like
' First(Fields!fieldName.Value, datasetName)' but in custom code, this obviously doesn't work.end function
I've been looking for a way to accomplish this, but it seems you cannot get data from a dataset through custom code (there is only the commandtext property). Also it is not possible to pass the Fields collection as a parameter, as I do not know the dataset name when in the report designer.
I hope my problem description is clear.
Does anyone know how to solve this issue?
I am trying to retrieve and manipulate the value of the stored procedure parameters in the following custom code:
Code Snippet Public Function ShowLoading(ByVal intOption as integer, byVal BasicLoading as string, byVal BasicHealthExtra as string, byVal RiderLoading as string, byVal RiderHealthExtra as string, byVal TotalAmount as string) As string
dim strRider as String dim strCompanyName as string strCompanyName = Fields!CompanyName.Value
select case strCompanyName case "and Plus Rider ": strRider = "Plus Rider" case "and Assist Rider ": strRider = "Assist Rider" end select return strRider
End Function
However, i got this error when I try to preview the report: An error occurred during local report processing, The definition of the report :
'/reportC' is invalid. There is an error on line 5 of custom code: [BC30469] Reference to a non-shared member requires an object reference.
Any help is greatly appreciated. Thanks in advance.
I have to create tablix report using data from 2 datasets. The data source for one of the dataset, DataSet1Â is Microsoft SQL Server and the data source for the other dataset, DataSet2 is Excel.
I have to pic 3 columns from DataSet1 and one column from DataSet2.
I am not sure if this is possible or not, we have two datasets and each one has an additional calculated field which breaks the value JobBilledExVAT into three years.
So it reports for example how much we billed in May 2015, 2014 and 2013.
I have got the table to display this when reporting on one dataset by grouping by year
The datasets both look similar to thisÂ
SELECT  Practice.ibvSalesByJob.JobBilledExVAT  ,Practice.ibvSalesByJob.[Year] FROM  Practice.ibvSalesByJob  INNER JOIN Practice.idvJobType
[Code] ...
The calculated field isÂ
=Switch(Fields!Year.Value = Parameters!Year.Value ,"15", Fields!Year.Value = Parameters!Pre1Year.Value ,"14", Fields!Year.Value = Parameters!Pre2Year.Value ,"13") The field I am looking to add together is below =Sum(Fields!JobBilledExVAT.Value)
If I do the below on the dataset associated with the matrix it displays the sum for each year correctly, I would however like to add the Sum(Fields!JobBilledExVAT.Value) from a different dataset (ABS1M) for the relevant year.
However this adds 2015, 14 and 13 from ABS1M and doesn't add them individually if that makes sense? With the calculated field it only shows Year under the main dataset heading not 15, 14 and 13 separately.
I was think of using LOOKUP however I don't know how this would work as 15, 14 and 13 are not displayed under the dataset.
I am attempting to set my custom properties in the UI I have created for my custom transformation. I can access them in the ProcessInput, but if I try to assign them a new value in my UI the values dont change.
I set the properties up in ProvideComponentProperties
I am having two datasets in the same report, the column names are the same, in both the datasets, Now How can I use the individual fields in same report. If I use (Fields!xyz.Value, "dsDataSet1") and (Fields!xyz.Value, "dsDataSet2") It is giving me syntax error.
How can I use both these fieds, I do not want any aggregates
...I guess that simply means that I can't access a package's variables within a custom log provider? Can anyone comment/confirm? Any other options/routes to achieving the same..?
I'm running rs2005 sp2, and the dll was made with .net 1.1. Before, there were no issues with this version crossing of .net 1.1 and 2.0.
In the RS IDE, the webservice call works fine. I've read that this execution is done with full trust - so I've tried to tackle the CAS issue.
When I try to call the webservice from the dll, I catch the exception, and it's: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Now what confuses me is, why is the version of WebPermission 2.0 when the dll is 1.1? Maybe there is translation done and the dll is really run w/ the 2.0 framework?
Anyways, this I've done are:
* Added this right before my webservice call. Is something missing? // We need to ensure that this library is permitted to access the webservice url // http://support.microsoft.com/default.aspx?scid=kb;en-us;842419 System.Text.RegularExpressions.Regex urlRegEx = new System.Text.RegularExpressions.Regex(@"http://server/.*"); System.Net.WebPermission p = new System.Net.WebPermission(NetworkAccess.Connect, urlRegEx); p.Assert();
* Gave the 'All_Code' group permission of full trust in both .net 1.1 and 2.0 configurations to see if it helped - it did not, and I checked the report after I did an iisreset. This should have done it!!
* I also tried changing: rsmgrpolicy.config and rssrvpolicy.config
and updated these lines to have version 2.0.0.0: <SecurityClass Name="SecurityPermission" Description="System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <SecurityClass Name="WebPermission" Description="System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
iisreset was done, and the code executed was still complaining about the permission request failing for WebPermission.
* These blocks were added to rsmgrpolicy.config and rssrvpolicy.config, in respective sections: <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="CompanyPermissionSet" Name="CompanyRS" Description=""> <IMembershipCondition class="UrlMembershipCondition" version="1" Url="file://C:/Program Files/Microsoft SQL Server/MSSQL.3/Reporting Services/ReportServer/bin/Company.RS.dll"/> </CodeGroup>
We use reporting services to report on our SQL 2005.
I wanted to have a function that translates a filter (parameter) in one RDL from IDs to Names to be able to show a summary of what the user selected when he executed the report.
Instead of writing this function in the .Code, I said great, lets use custom assemblies.
PROBLEM: I see examples on how to enable a function in such dll access to DB, but they all hardcode the connection string in the vb code. that seems useless to me. Each customer will have different server name, I need to get the connection string from the sme (shared data source) used in the catalog's folder. just like the RDl is using it. how do I do that?
I have following query in stored procedure Select ContractId, Version, CreateDate, body, IsCurrentFrom CRM_Contracts where ContractId=@ContractId I am trying to access the value of IsCurrent field in Code behind using sqlDataSource to hide a radiobutton list in Formview control's when it is in Edit Mode. How can i do this.
Does anyone have code to access data? I want to create a sqldatasource control on the page, but would like to programmatically/manually/code-behind-wise to fill in my queries and their parameters. Thanks!
I have the following datasource... <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ***%>" ProviderName="<%$ ***%>" SelectCommand='SELECT "var1", "var2", "var3" FROM "tbl1"'> </asp:SqlDataSource> Would it be possible to use VB code to read the reasults from this datasource? (There are conditions that restrict me from running the query itself through VB code.) As always, any help is greatly appreciated. Thanks!
I am not able to access SSIS variables which are defined at Data Flow Task in a custom component. This custom component is developed by me in C#. How can i access these variables?
Please let me know if theres a way to access SSIS variables.
Hey guys I have a problem I am trying to solve using custom code but I am open to other solutions.
Situation: I have multiple reports that the user can see. Example (Move In Corp. report, Move In Region report,Move In Division report, Mid Year Corp. report, Mid Year Region report,Mid Year Division report etc.) I have a stored procedure that returns all the information needed based upon the UserID being passed from the report to the stored procedure.
Goal: When the user logs in I want to be able to foward the user to a specific report based upon their userid (global in RS). I currently have three textboxes(Move In, Mid Year, Year End) with navigation enabled to jump to another report. The report to which the user is passed to is determined by an expression which is something like this for the Move In text box =IIF(Fields!orgtypeid.Value = 1,"Move In Corp","Move In Region"). The orgtypeid.value is returned by the stored procedure. I want to be able to forward the user a specific Move In report (Move In Corp, Move In Region, etc) without having the user select the textbox.
Hello, this is probably a pretty easy one. I have made a report, and added custom code in the code tab on the report properties. But when I type code.whatever in a text box expression my function does not show. Does anyone know what I am doing wrong?
I am trying to access HttpContext.Current in my report code section (report properties) since I have to look at a cookie. However, HttpContext.Current is always null. Has anyone managed to access HttpContex.Current from a report?
I am trying to find ways around the limitation of not being able to resize columns based on the text input. I am dynamically setting what values a column is getting from my query. I am wondering if I can access the table (and thus, the columns) from within the custom code.
For example:
Public Function Whynot() As Integer Report.table1.TableColumn1.Width = .... table1.TableColumn.Width = .... Return 0 End Function
Neither of these seem to work, anyone else have any ideas?
I developed a ConnectionString assembly in custom code a while back. Now it won't work. I've changed boxes since. My question is do I have to have SQL Server and Reporting Services on my development machine to run Custom Code assemblies?
I put my dll in the PublicAssemblies folder. I see that I need to put my dll in C:Program FilesMicrosoft SQL Server80ToolsReport Designer but I don't have that folder.
When I try and set the ConnectionString to "=ReportingLibrary.ReportingLibraryFunctions.ConnectionString(User!UserID)", I get "Unrecognized Identifier." I checked the reference and it was still there from when the project was working before.
Code Snippet using System; using System.Security.Permissions; using System.Configuration; namespace ReportingLibrary {
public class ReportingLibraryFunctions {
public static string ConnectionString(string userName) {
I have been stuck in a problem for a while now. I am trying to count the number of groups. I tried soo many things and nothing worked . Now I want to try to write a function that does the counting for me.
Can somebody write me an example of a cutom code that can be called from expression. So my custome code should be something like that
Public int CountFun(int counter) { Return counter= counter +1;
}
Also how do I call this method from my expression? i am going to call it from a field inside the groups, so each time the group is implemented i add one to the counter.
I'm using a GAC-installed assembly as part of a Reporting Services (2005) report. The code does not need any permissions beyond execution. All it does it take today's date and calculate last week's start and end date. It's all just datetime manipulations. All methods are static.
In the VS2005 report designer, I can do everything fine. The code runs as expected and defaults the parameters to the right date.
When I upload the rdl to the Report Server, I get the message "Error during processing of €˜Start€™ report parameter. (rsReportParameterProcessingError) ". If I override the "Start" parameter, it doesn't give me that error anymore. Start should be the Sunday of the previous week.
I have deployed the signed assembly to the GAC on the report server as well as the bin folder for reporting services. Because it doesn't need anything beyond execution, I shouldn't have to modify any config files, right? I have already restarted IIS & the Reporting Services service.
I've got an issue where I want to sum the group values and not the details, the reason is because I am hiding duplicate records. Here's how my Layout is setup.
This gives me incorrect results and I can't figure out why. Here's how it shows on my report:
Part Number Quantity
Cost Regular Subtotal Method Using Custom Code
Part 1 4,000
1.49 $5,947.20

0.20 $5,380.20
Customer 5
$66,891.69 $3,922.59
Grand Total
$141,301.23 $0.00
The issues brought up from the duplicates is shown in the "Regular Subtotal Method" column (there are 2 detail records for Customer 1-Part 1, which is why it is doubled). I can't use a distinct on the SQL query because there are other fields (not shown) on the report that are different.
As you can see, the GF1 (Customer #) shows the subtotal from the previous group, and the Table Footer (Grand Total) shows 0. Why is this?
i was developing some custom code to do a running total in a matrix, and i have noticed some odd behaviour with the InScope function. I am doing year on year reporting, so i have two row groups on my matrix: the first is on month (matrix2_Calendar_Month), the second on year (matrix2_Calendar_Year).
I needed to total the number of days covered by the months i was reporting on, so i wrote some very standard code to do this, along with an expression in that column of the matrix:
Code.AddDays() calculates and returns the number of days in the month of that year on that row. Code.getBounds simply returns the lower and upper bounds of the array, plus its contents (so i can inspect them). This is what is returned in the report:
Month / Year

If you look at the output in the total row, you will see that Code.AddDays() has been called one extra time at the end, with Feb 2006 as its parameters, thus adding an extra 28 days to the running total. Why is Code.AddDays called on the total row, when i should be out of the scope of both the row groups? (Note: this happens for whichever row group i use in the InScope check in the expression).
Here is the custom code used for all this:
Dim numDays()
Public Function AddDays(ByVal month As String, ByVal year As Integer) As Integer Dim thisMonth As String
Dim upper As Integer upper = 0 On Error Resume Next upper = UBound(numDays) + 1 ReDim Preserve numDays(upper)
I have a custom C# assembly that my report is calling with embedded code that is called from fields in a reporting services table. The value comes back fine, but I need some of the values to be indented, so I have tried all of the following and every time the spaces are cut off. Spaces work when not using embedded code.
I tried the following in the table cell =Space(3)+Code.<<String Function Name>> and I tried =" "+Code.<<String Function Name>>
Then I tried the code in the assembly and in the embedded code with the same result. No matter where I put the spaces they get cut off. Any ideas? I tried characters other than spaces and they came back fine.
I'm trying to run a DTS package, and cant find an easy direct way to run it. It seems like the easiest solution would be to throw a custom error- then the server notices the error and runs a custom job, and the custom job runs the DTS. This is a roundabout way, but seems like it would be the simplest solution.Anyways, how do I throw the error in my code? Do I just write a throw 3829 statement? Also maybe this is a very bad way to do this- any suggestions?
Is it possible to add a multivalued parameter to a report from C#? I already have a C# .dll which I reference in the report. If so, could someone give some hints on how to do it?
As I searched the net for an answer to this, I came across ReportExecutionService. It looks like it's what I want, but I cant find the dll to reference in order to used this class. Does anyone know?
If it is not possible to do this from C#, then can someone please give an example on how to do it from Custom Code?
HI all, I am having a problem while trying to create a list item through SSRS.The scenario:I have created a SSRS report which has custom code. the report has some parameters. The code accepts the parameters and tries to create a list item in moss. I have added the required references. This works fine as long as I work in VISUAL STUDIO IDE. When I deploy the report to report server it throws an error in the code.Can anybody help me in this...?Regards...
