Row colouring in rdlc report

Actually I need t开发者_StackOverflowo color 2 row one color and next 2 row another color ,alternatively in rdlc report. For example 1st and 2nd row should be in red color and 3rd and 4th should be in yellow.Again 5th and 6th should be in red and 7th and 8th should be in yellow ...etc.

It is very similar to what you would do if you were coloring every alternate row, you just need a small change to the Mod calculation:

= IIf(RowNumber(Nothing) Mod 4 < 2, "FirstColor", "SecondCOlor")

This is untested, but should be enough to get you going.
