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. You should be able to preview the report and see the text that you added to the text file. Next copy the dll and the text file and put the text file in the c: 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. 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:. 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 execute , but not to use protected resources. Next in your assembly attribute file AssemblyInfo. Security or using System. 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 refesh button on the report toolbar and you may have to restart the reporting service. Hopefully you were able to get everything to work. Now you should have a basic understanding of how to use custom code with reporting services.
If you have drop leave a comment and I will try to address it. You are returning an array item an array of strings into a text field. Instead, try returning a plain string. If you would still like to return an array list, you must basically bind it to a list control in your RDL. You can definitely do that with dataset extensions. However, I am not sure if there is any other easy way.
Check the proprties of the list control and see if it allows you to directly bind to an array list. You can create the same stored procedure on SQL Server and load parameter values from that procedure. GetValues , where the function uses a For loop to create the values. I changed the return type to Array as suggested by prashant sable, but the select list is still grayed out, it does not work. And coldice is correct in saying that the access modifier should be Public. In my digging around I found an article by James Kovac from that pointed out why this is not possible.
The Parameters class has a get method, but no set method. My current workaround is to just hard code the list of values, but if your value list needs to be dynamic then your only choices are database queries, web services, or custom assemblies.
