Hi Boyan Penev,
why do you need parameters?
Your Resultset of the StoredProcedure has only one row containg the value of the colors. So, my meaning is that you can use an expression like this in the color-Property:
=First(Fields!HeaderColour.Value, "usp_CTL_Get_Report_Colours")
Then also the disadvantage of the parameters is eliminated.
With kind regards,
Markus Krenn
