And thank you to Tim for 6 great articles about Reporting Services! Find all 6 here.
Here's an excerpt from the article:
SQL Services Reporting Services is a very powerful tool and with each new release, it grows in functionality. However many users find that the expression builder functions do not quite do what they need. Fortunately, Microsoft has provided a powerful means of extending the capabilities of a report, virtually without limit, by using the custom code capability. While custom code can access custom assemblies, the string manipulation functionality discussed here uses only the core .Net assemblies which are available by default on the Reporting server and so requires no explicitly referenced assemblies.
String Manipulation Using Custom Code
The SQL Server Reporting Services, Power View MSDN forum contains numerous questions asking how to extend the string manipulation capabilities of Reporting Services. In some cases, the solution can only be achieved through custom code. We will explore three different string manipulation scenarios requiring custom code in SSRS reports:
- Concatenating Data Column Values Into a Single String
- Counting Occurrences in a Concatenated String
- Sorting Elements of a Concatenated String
Concatenating Data Column Values Into a Single String
Occassionally a report author may have a need to display detail records in a grouped table in a single cell rather than separate rows.
My dataset returns multiple rows of data for a given grouping with only one field (we will call it Grade) varying across those rows. I want my report to display a single line for a group with all of the values of Grade for that group displayed as a concatenated string in a single cell of each group row.
Add the below function to the custom code module of the report:
Private Num AsString=""
Private tempstr AsString=""
Function AggregateString(Group asString, Val asString) as String
If Group = Num Then
tempstr = tempstr +", "+ Val
Num = Group
tempstr = Val
With this custom VB.Net function, you can create a delimited string that concatenates all of the specified detail records of a group using the RunningValue function.
