If you want to add a group row header to an existing group row in order for that group row header to repeat on each group break, do the following.
- In the Row Groups Panel below the report designer in the Design tab, right mouse click the group where you want a group row header to appear above it and select, ‘Add Total’ then choose ‘Before’.
- Add an expression to the column(s) of the group row header that you just created that you want displayed to the client based on the group break.
For example, let’s say you have two groupings, the first being TruckModel, the second being V8Engine with a value of Y or N; Y being that it is a V8. If you created a row group that breaks on V8Engine, the group row header will appear only when the V8Engine changes for the specific TruckModel. In the expression, you can check for the value of Y, and if true, display V8 else V6 like so:
=Fields!TruckModel.Value & " " & iif(Fields!V8Engine.Value = "Y", "V8", "V6")
This collection already contains an address with scheme http.
There can be at most one address per scheme in this collection.
If your service is being hosted in IIS you can fix the problem by setting ‘system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled’ to true or specifying ‘system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters’. Parameter name: item
In .Net 4 and above, you can add this to the web.config to resolve the issue:
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
Let’s say you have a table called ‘car_make’ and another table called ‘car_model’. There is a one to many relationship between make and model.
You want to bring back a result set of all makes, 1 row per make, but you want only 1 generated column for model that has all the models concatenate into that 1 column.
You also want to add carriage controls so each model will appear on a separate line in your row on your report.
Let’s say you have 4 models for your 1 make of Chevy. Here is the output of what you are striving for:
The following SQL will give you this result:
left(ModelsConcat.Models,LEN(ModelsConcat.Models)-PATINDEX('%[^'+CHAR(13)+CHAR(10)+']%',REVERSE(ModelsConcat.Models))+1) As CarModels
OUTER APPLY (SELECT DISTINCT SUBSTRING((SELECT DISTINCT (m1.model + ', ' + + char(13))
FROM car_make AS m1
WHERE a.make = m1.make
ORDER BY (m1.model + ', ' + char(13)) For Xml Path(''), type).value('.', 'nvarchar(max)') ,1,2000) AS Models
FROM car_model) AS ModelsConcat
FROM car_make a
In your expression, you simply reference the field like this:
