- Open the report in layout mode. The RDLC kayout of your report should be on display
- Go to column groups advance mode
- A series of static groups is created
- Select a static group for the row you would like to repeat
- Set the properties of that Row static group as follow
KeepWithGroup ="After"
RepeatOnNewPage = "True"
The procedure is true for both Report builder and Visual Studio
