Note in VS , you will find the Report Properties under Extensions. In the custom code window, we can easily add the following code to handle the divide by zero problem. This results in the following report. The first and second argument in the code are the numerator and denominator, but the third item determines what is displayed when a divide by zero results. In this example, nothing is displayed. We could have easily had the value be 0 with the expression above. Using custom code to establish a set color scheme is a common practice.
You can see these tips related setting custom colors: Different ways to create Custom Colors for Charts in SQL Server Reporting Services and SQL Server Reporting Services Custom Code Assemblies. However, most of those use a fixed interval range set, such as 0 to 10, 10 to 20, etc. What happens if the values do not fit into these fixed range of numbers or if the numeric values are ever increasing? Custom code can again help us solve this particular problem with just a bit of help from a SQL query. Continuing with our example data, we will now set the background color for the Tax column.
Since this amount can vary greatly, we actually need to calculate the maximum and minimum tax amount for the selected Sales Territory. Thus we want to generate a single maximum and minimum tax amount for the report. The maximum Tax Amount value will be passed to the custom code to set the color. The below code is added to the custom code set; we pass two arguments to this public function. The first is the actual value and the second is the maximum value from the above query. Next, two variables are created, the first one, BackgroundColor, for the resulting background color and the second, MeasureMaxThreshold, is used in the calculation for determining the intervals for each color. In the below example, we create 5 intervals, but you could use any number of intervals, as long as a color is defined for each interval.
To make this determination, we use the maximum amount and divide it by 5. Interval 1 is then from 0 or less to the maximum amount divided by 5; we assign the color of MediumSeaGreen to this interval. These intervals continue until we get to the value for interval 4. Anything greater than that value is assigned a fixed color. The next step in the setup process includes creating a parameter to hold our maximum tax amount value. With the SQL dataset setup, the parameter created, and the code added to the report properties, we can now implement for the Tax Amount textbox. As shown below, the function uses two arguments; the first argument being passed to the function is the Tax Amount value. The second argument is the maximum Tax Amount from the aggregate query; this value is sourced through a parameter.
The aggregate data set cannot be called directly from a visual the Tablix visual which uses another dataset. One alternative that could be used is to include the maximum and minimum values in the main data set. As illustrated below, we now have a flexible way to implement conditional formatting in a textbox without using fixed interval values. The color coding will adjust as the max value adjusts; note a large outlier value could impact this setup. One potential caveat to using the report code is that it must be copied from report to report or utilized in some sort of SSRS report template. However, once perfected, the code can be easily copied from report to report and can be used to control many options and properties including items, such as, font and background colors, and custom, complex formulas.
This particular area of knowledge centers on being sure to know your report audience and what their desired output options will be. Using these pieces of information, you can cater the end version of your report to that particular audience. A reporting being exported to Excel has a very different look and potentially navigation path then one being exported to PDF; a PDF report is often printed, while Excel reports are often used for further processing. For example if you have a report that will always be exported to Excel, you can format the report in such a way that it exports to Excel in an appropriate format for easier reading in Excel.
You may want to export to multiple Excel worksheets as described in this tip: Export SQL Server Reporting Services Report Data into Multiple Excel Worksheets. Finally one of the newer features to exporting that I have found helpful in certain instances is exporting a report to Power Point. This tip describes that process in detail: Exporting SQL Server Reporting Services Reports to PowerPoint. All these different methods bring us to another code set; one in which we can do these exports automatically while at the same time passing a render format for example Excel, Word, PDF, etc. and any parameter values. This information is passed via URL string commonly known as URL access. Using this method, we can actually automatically download the report.
The commands are initiated from the report server command set, rs:. We will cover several of the report server command, but SSRS also includes the report viewer rv: commands which are beyond the scope of our tip. In order to complete the direct export of the desired file, we need to build a URL string that tells SSRS each of the following items:. In In order to completely automate the export of the file, all required parameters must either have a default value or a parameter value must be included in the URL string being created; as shown above, multiple parameters can be sent in the URL string.
Additionally, we could just as easily change the rs:Format to Excel or Word, or even give the report consumers a choice via a parameter or clicking on a particular text box. So for our example create a new Visual Studio Class Library project in either C or VB. Call it MyCustomAssembly. Next rename Class1 to SayHello. To the SayHello class we will add one method which is shown below. Once you're done with the code go ahead and compile the project. Once you've gotten your assembly compiled follow this link for instructions on how to add a reference to your code.
Note: You only need to add a reference. The Class section will only be used if you're class has instance methods versus Shared or static methods. Hello ". You should be able to preview the report and see "Hello from My Custom Assembly" on the report. So you have now used both embedded code and custom assemblies. Before you can deploy the report you need to copy the MyCustomAssembly. Once you have copied the dll file you should be able to deploy your report to the server. But what if you want to actually do something interesting like grab values from a database or use a web service? To do that you will need to modify the Code Access Security CAS settings for reporting services.
There is actually a comprehensive article on this topic here. I would recommend you read that article. There is also a good introduction to CAS in general here and here. The goal of this article the one you're reading is to give you a quick-and-easy example that can get you started. So we will attempt to read a value from a file and return it. First create a text file called hello. In the file add the text "Hello from a text file! Next add the following method to your SayHello class:. ReadToEnd reader. txt" { return reader. ReadToEnd ; } }. Next compile you the project. Once the project is compiled you will need to remove the old reference in your report and add the new reference and copy pver the new dll you will have to close the report project to do this. HelloFromFile ".
You should be able to preview the report and see the text that you added to the text file. When you try to view the report on the server you won't see your message. Instead you should see " Error". In order to make this work on the server we need to follow the steps outlined in the CAS article. The first step according to the article is to: 1. Identify the exact permissions that your code needs in order to make the secured call. If this is a method that is part of a. NET Framework library, this information should be included in the method documentation. Next we need to: 2. Modify the report server policy configuration files in order to grant the custom assembly the required permissions. Note: Be careful when you edit this file. I would highly recommend making a backup copy of the original file before making any changes.
This file is an Xml file and you must be sure that what you add is valid Xml. Then build a new string by iterating all items in the Character array and adding line breaks using vbCrLf between each character in the string. At last return the resultant text or string back to the caller of the function SplitTextWithLineBreaks. And you can call this custom function by a sample expression like Code. SplitTextWithLineBreaks with the sample code shown below:.

Vasant Raj , first published: The Code tab is used to add the code. This code can contain a class or functions. Only VB. NET can be used. The References tab is used to specify the external DLLs to be used. This DLL can be created in any language. The important step in the References tab is the creation of the objects. The DLL functions can be accessed using the object name specified. If a DLL is using some additional libraries, it has to be added as a reference. For example, System. Xml has to be referenced if any XML functions are used. Each time modifications are done to the DLL, the new version has to be copied to the above folder.
The functions can also take values as parameters, which can be any field from a dataset or user specified value. This example will show how to add and use the code in the reports. Also, the use of DLL will be shown. The sample DLL for this example is created in C Create a new report [name of the report is TestReport. rdl] and open the Report Properties from the Report menu. Add the following code in the Code tab:. The code contains a CLASS having a function and a property in VB If a class is present, then an object is required to be created for accessing the functionality. If no class,. Create a simple DLL having properties and functions that are returning basic data-types values and taking parameters.
The code for the DLL is in C , but it can be in any language. Name of the library having this class is TestDLL. Add reference to the DLL by browsing to the PrivateAssemblies folder. Also, create objects for the classes. The objects are required for accessing the functionality. The parameter value for MyNewFunction is the name of the report. As we have seen that it is very easy to access code from DLLs and also add our own code, this can be used for performing complex operations and conditional processing of the data. The reports will no longer. be used only for displaying data. Using this functionality, the reports can now figure out what to do with the data and be more powerful i. Log in or register to rate.

In this article, I will show you how to leverage the Reporting Services unique extensible architecture to supercharge your report capabilities. First, I will explain how embedded and custom code options work. Next, I will show you how you can leverage custom code to author an advanced report with sales forecasting features. Adding Custom Code To Reporting Services Vasant Raj , first published: Introduction SQL Server Reporting Services has techniques for developing reports that can have their own code and also can access code from custom librarys i. Earlier, if we look at any report, it will have a designer for creating the layout and some method through which we can assign the data for the report.
Reporting services add one more step to this process i. In this article, we will see first look at the option that allows adding code and creating objects for accessing the DLL code. Adding code Create a report or open an existing report. Open the Report Properties option from the Report menu. Dialog box opens. To Remember: If a DLL is using some additional libraries, it has to be added as a reference. Only the functions returning basic data-types [like string, integer] are supported. The DLL has to be referenced in the References tab from this path only. Keyword code to be used while accessing the custom code.
Example: This example will show how to add and use the code in the reports. Add the following code in the Code tab: PUBLIC CLASS TestVB FUNCTION MyFunction AS STRING RETURN "Value returned through a FUNCTION from Code Tab. If no class, then it can be accessed directly. Add this code in the Code tab. namespace TestDLL { public class Test { public string MyProperty { get { return "Data accessed through PROPERTY from a DLL.
