Writing custom code for reporting services - Intellipaat Community
For our first trick we will write some embedded code. To get started open your browser to this page. On that page under embedded code you will see the following statement. To use code within a report, you add a code block to the report. This code block can contain multiple methods. Methods in embedded code must be written in Visual Basic. NET and must be instance based. So let's get started and add some embedded code to a report.
Next click this link for instructions to add the embedded code to the report. To add code to a report. SayHello " without the quotes in the textbox. You should now be able to preview your report and see "Hello from Embedded Code" on the report, writing custom code for reporting services 2020. That is as far as we are going to take embedded code I also found this article which talks a little more about embedded code.
At this point you should be able to deploy your report to the server and run it on the server. The next topic is custom assemblies. This is a much more useful feature since you aren't constrained to writing code in VB. Net on a small dialog in the report designer. You can use Visual Studio and your language of choice. 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.
First create a text file called hello. In the file add the text "Hello from a writing custom code for reporting services 2020 file! Next add the following method to your SayHello class:. Note: You will also need to add Imports System. IO in VB and using System. IO in C. Next compile you the project.
Once the project is compiled you will need to remove the old writing custom code for reporting services 2020 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 ", writing custom code for reporting services 2020. 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:. 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:. 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. Next we need to add the code group. Again, based on the example in the CAS article we can add the following Xml. We have to put this under the correct CodeGroup node in order for it to work correctly.
So you will need to put it under the last code group, but make sure it has the same parent node as the last code group. To do this just insert it before the second to last ending CodeGroup as shown below:. Here is the code group to add. Assert the required permissions as part of the method in which the secure call is made. This is required because the custom assembly code that is called by the report server is part of the report expression host assembly which runs with Execution by default.
The Execution permission set enables code to run executebut not to use protected resources. Mark the custom assembly with writing custom code for reporting services 2020 AllowPartiallyTrustedCallersAttribute.
This is required because custom assemblies are called from a report expression that is a part writing custom code for reporting services 2020 the report expression host assembly, which by default is not granted FullTrust, thus is a 'partially trusted' caller.
For more information, see "Using Strong Named Custom Assemblies," earlier in this document. Next in your assembly attribute file AssemblyInfo, writing custom code for reporting services 2020. cs in C or AssemblyInfo. vb in VBadd the following assembly-level attribute and add Imports System, writing custom code for reporting services 2020.
Security or using System. Security :. Once you've done this, recompile the assembly and copy it to the server. You should now be able to execute the report and see "Hello from a Text File!
If you still see the error need to make sure that you click the refresh button on the report toolbar and you may have to restart the reporting service. Source: bryantlikes.
