Reporting Services :: Using Custom Code To Create A Heatmap?
May 21, 2015
Below is code I am using to create a heatmap in SSRS. THe code seems to be working well except for one glitch. Sometimes numbers in the "middle of the pack" are white. Obviously they should be one the of colors listed below. Why numbers would be white when I declared only white for IsNothing.Â
 Public Function GetHeatmapColor(ByVal textBoxValue, ByVal minDataSetValue, ByVal maxDataSetValue) As String
    Dim colours As String() = New String() {"White","DarkGreen","Green","ForestGreen","LimeGreen","YellowGreen","Yellow","Gold","Orange","DarkOrange","OrangeRed","Red"}
        If IsNothing(textBoxValue) = True Then
      Return colours(0)
i need to create a 32 tile Heatmap in SSRS 2008 R2,I am not too concerned with adjusting colours by values, I just need to get the 32 tiles in place in the report initially, then extend it with more functionality later on.
I created a class library which uses a web reference My SSRS report uses the class through its custom code I copied the dll & dll.config of the class library to the VS2005 private assembllies and the report works I copied the dll & dd.config to the reportserver bin and gave the assembly full trust by adding the necessary code group I even added a code group the give the dll.config file full trust as well Yet on Repost server, the report does not work Any ideas I suspect it is a permission problem
but gives me the "Unrecognized identifier" red squiggle.
My FormatString function (in the rdl file) is this:
Public Shared Function FormatString(ByVal Decimals as object) As String  dim format = "N0"  if not (Decimals is nothing or Decimals is System.DBNull.Value) then    dim decs as integer    decs = Convert.ToInt32(Decimals)    if decs>0 then      format = "N"+decs.ToString()    end if  end if  return format End Function
I have a SSRS report that parses RTF to TXT and displays it in a report.  The report works fine and everything displays correctly.  The subscription email, however, contains a report with errors: Request for the permission of type 'System.Security.Permissions.UIPermission, mscorlib, Version=2.0.0.0, Culture= neutral,PublicKeyToken=b77a5c561934e089' failed.The report contains embedded code as well as references to System.Security and System. Windows. Forms.  I've updated .....Reporting ServicesReportServer ssrvpolicy.config and ....Reporting ServicesReportManager smgrpolicy.config to change permissions to FullTrust.
I wrong a custom code in my report - Public shared Function Myfunc and in the header textbox - I tried to reference this code = Code.Myfunc.... the Myfunc gives an error Unrecognized identifier.The code is written in the report properties = Code Tab.
I have a requirement in which i have to create a custom .net class library for Ex:-I retrieve password(s) from a thrid party component. Below is what i am doing.
(1) Created a custom class library which reads a custom .xml file from a drive Ex:- "D:MyAppMYAppCofig.xml" and sets to my properties of my custom class library and inside it i created an instance of third party component's class and passed these values. Since i need to use this .net custom class library both in web and ssis/database side i am using this custom .xml file.
(2) After validating passed data (properties set in custom .net class library) the thrid party component instance object created in my custom .net class libraty returs a password to me own custom .net class libray.
(3) This password I use in my web app for connecting to database. This code is working fine.
(4) My question is how to execute a custom .net class library code through ssis and to use the my same custom .net class library and pass the password to my SSIS component / taks so that that code block also uses the returned password to connect and do any needed tasks? In other words how to use custom .net class library from SSIS.
My Environment is as follows:- SQL Server is : 2008 R2 VS.NET 2013
For custom authorization, I am overwriting the CheckAccess method.
But how do I know what I am trying to access in CheckAccess method? I need to know what report the check access method is trying to execute for our requirements.
I got authentication to work without too many problems, and it authenticates by querying my custom table. I want to also maintain my authorizations in the same manner. I want to be able to define in my own tables that user test1 has permission to view reports 1, 3, 5, and 8. User test2 can view reports 1,3,5,8, and 9. User test3 can view 1, 2, and 4. Etc.
The authorization extension, contained in my version of Authorization.cs is where I expected to be able to do this. I wanted to be able to write code that queries my own tables and says, "does this user have permission to view this item?" Getting the this user portion is easy as is obvious in the many checkAccess methods. But being able to tell what item I am currently dealing with has proved impossible from the context of Authorization.cs, which implements IAuthorizationExtension. Knowing what type of item I am dealing with is obvious, but I need to know something that uniquely identifies the exact item I am dealing with.
How can I determine in checkAccess or any of the other available methods what "thing" they are looking at? What can I examine to determine that for instance this particular authorization request is against "Report 1"? It seems that if I was allowed to completely override Authentication to use my tables, I should be able to override Authorization to do the same. Is this possible or am I missing something?
I need some help regarding Custom Colors implementation for Charts in the Reporting Services.
What we are trying to do is to make every color for every Series(see example below) to be a customized Corporate color.
For example each of the series on the Chart should be in specific Custom Color:
Series 1 - "LightBlue" Series 2 - "LightYellow"
Series 3 - "DarkBrown"
All I found from MSDN is how to do it in the Chart Properties in a Code section (right click on the report outside the chart -> Properties -> Code tab -> paste the Custom Code ).
And then to use it in the Chart color definition as:
Code Snippet=Code.GetColor( Series# )
But we are trying to do it in a separate C# class that would be updated only in one place, instead of changing 30 reports each time something is changed. So that it could be generic.
The C# class:
Code Snippet
namespace CustomColorPalette
{
public class CustomPalette
{
public CustomPalette()
{
}
public static string GetColor(string GroupingValue)
Error 303 [rsCompilerErrorInCode] There is an error on line 2 of custom code: [BC30451] Name 'CustomColorPalette' is not declared. c:developmentvoyagerreportsvoyager convert reports.rootvoyager convert reportsReport_007D.rdl 0 0
2.
Second way I tried:
Then I put a code into a Custom Code section of a report:
And after compilation I am getting an error like this:
Error 302 [rsCompilerErrorInExpression] The BackgroundColor expression for the chart €˜chart2€™ contains an error: [BC30456] 'X' is not a member of 'ReportExprHostImpl.CustomCodeProxy'. c:developmentvoyagerreportsvoyager convert reports.rootvoyager convert reportsReport_007D.rdl 0 0
Is there any workaround? Or all I can do is to make the Custom Colors manually in each report, and if something need to be changed - I will need to change it in each report separately
I have problem with SQL Reporting Services, actually i want display the 3 parameters in a single line in a report i.e. in the while preview of the report and after deploying the report (by default it is showing 2 parameter per line). for example if have 6 parameters i wanted it display it in 2 rows and 3 columns format.
I am working on SSRS report with project server 2013 and I want to add custom dll in SSRS report.I have create dll first then add into GAC Assembly After that i have add this dll in report project in SSRS.when i have try to deploy and build report...
.An error Occurred during local report processing.
Failed to load expression host assembly.

Hi all, We are displaying an SQL Server 2005 Reporting Services report in our ASP.NET 1.1 application by accessing the report through URL and embedding the same in an iframe HTML web control. The user can export the report contents into CSV format by making use of the export functionality provided by Reporting Services. Now we have been asked to display a warning mesage to the user when the no. of records in the report exceeds 1 million i.e. if the no. of records in the report exceeds 1 million and the user tries to export the report to CSV format by clicking on the "Exprot" link button, we need to display a warning message to the user. My doubt is whether this can be done in Reporting Services. Are there any programmatic interfaces exposed by Reporting Services which might help us implement this requirement ?
I was trying to write a custom legend text for a chart that I have in SSRS. In the chart I have a Bar chart and a Line chart. I have two values coming from a dataset. One is a running value. All the series values are from year dataset.
I need to get a custom legend text for the three data series looking like this. "2013- Mth", "2014-Mth". Year should be dynamic and coming from the dataset.
I tried writing an expression in the series legend option as shown below.
But I don't get the required text for the chart. I only get the default series text for the legend. If I only write a text without the dynamic year taken from the dataset columns I get the custom text. But not when I concatenate the dynamic year series with the static text. Any property to enable/disable?
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.
This is a subject that has been brought up before but I have not seen a definitive answer/solution. We have implemented a custom authentication extension (forms authentication) for reporting services and it has been working just fine under "normal" conditions; "normal" being users logging in, viewing reports, and then moving on. Recently some reports were created by our report group and they contain Dundas gauge controls for "dashboard" style reports. These reports are meant to be up all day and they post back every few seconds because the data they present is mission critical. This of course exposed the inability of the reportviewer control to stay in the context of Report Manager when it comes to the cookie exchange and authentication thus resulting in the following error: <html><head><title>Object moved</title></head><body> <h2>Object moved to <a href="/ReportServer/logon.aspx?ReturnUrl=%2freportserver%2fReportExecution2005.asmx">here</a>.</h2> </body></html>
I created a quick ASP.NET web application and added the reportviewer to it, implemented IReportServerCredentials and the report came up as expected but behaved the same way as it did in Report Manager. Same with a Windows Forms application.
Increasing the cookie timeout in the forms authentication tag is an option, but not an attractive one. Extending the reportviewer control is also an option, but I don't know if that is a good candidate right now because I don't see anything extensible yet.
Is this just the nature of RS with custom authentication or is there a viable solution out there right now?
Any and all answers are much appreciated and I thank you in advance.
I'm getting the below mentioned error when i tried to open the sample reporting services code in Visual studio 2005
The application for project 'C:Program FilesMicrosoft SQL Server90SamplesReporting ServicesApplication SamplesFindRenderSave SamplecsFindRenderSaveFindRenderSaveCS.csproj' is not installed.
Make sure the application for the project type (.csproj) is installed.
In the Project types in Visual stuido i dont have Visual Basic projects or Visual c# projects.Please let me know how to install these projects types on the existing Visual studio and pls give me the link for downloading these project types.
I read that this sample is included, however when I install the samples the other three are in the "Extension Samples" directory but the "Custom Report Item Sample" is missing. Can anybody please tell me where I can find it?
I have a SSRS report that uses a custom library. The custom library returns a string values, and I have tested this with a windows application.In the SSRS report. I have set the expression value for a text box as  =CodeReportingLibrary.CodeReportingFunctions.GetImage(1232)
However, when i preview the report the text box value shows as #ERROR. I checked the error list and I get a warning message : Warning 1 [rsRuntime ErrorIn Expression] The Value expression for the textrun ‘Textbox5.Paragraphs[0].TextRuns[0]’ contains an error: Attempt by security transparent method 'CodeReportingLibrary.CodeReportingFunctions.GetReferenceImage(Int32)' to access security critical method 'Microsoft.

TfsTeamProjectCollection..ctor(System.Uri)' failed.  Assembly 'CodeReportingLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is partially trusted, which causes the CLR to make it entirely security transparent regardless of any transparency annotations in the assembly itself.  In order to access security critical code, this assembly must be fully trusted.
I have updated the rssrvpolicy.config in ReportServer folder, to include my custom dll.
I am creating a SSRS report which would be executed by User manually through ReportServer URL.User would be generating the SSRS report for different Customer ID based on ad-hoc basis.
I am passing CustomerID as input parameter to the report. Is there any way to get the manually generated SSRS report name as 'Report_CustomerID_TodayDate.xls'.
E.g.If User is generating report for Customer ID 123 today then report name should be 'Report_123_07092013.xls'
Is it possible to have a custom start date parameter on a report? I would like to have a cumulative daily report for the week, Friday to Thursday. The final daily to run on the Friday, then the next week begins.  I have a enddate, which is today()-1 (for previous day); I need a start date to be variable.  In other words,
On a Monday, report pulls data from last Friday to Sunday; On a Tuseday, report pulls data from last Friday to Monday, On a Wednesday, report pulls data from Friday to Tuesday, etc, until on Friday, the report pulls data from last Friday to Thursday.
I am using Custom Data Processing Extension to call a stored procedure. Iam getting following error when creating a dataset in report designer using the extension. I wrote the code in c#.
