I have an RDLC report with a sub-report that I want to be A4 paper in height. The number of rows in the sub-report may vary, so I placed the sub-report in a rectangle so that if the sub-report is short the rest of my report doesn't shrink. According to the documentation rectangles are fixed size. This works fine when I show the report on a web page, but when I run it in a ReportViewer in a WinForms app it shrinks!
Is this a known problem and does anyone have any ideas about what to do about it?
Six minutes later, I find the answer to my own question...
By default the ReportViewer is displaying the report in Normal mode - (which looks wrong to my mind). Setting it to Page Layout mode corrects the problem.
In VB.NET this was done with:
Me.ReportViewer1.SetDisplayMode(DisplayMode.PrintLayout)
Set all textbox CanGrow is False, then rectangles are fixed size
