Is there anyway to achive the following, easily? I have quite a few TDateTimePickers that are used to represent dates read in from a Database. When the values are read in from the database, the DateTimePickers are set to represent them, when the user changes the data, the values of the DateTimePickers as the basis of the update SQL statement. Now the problems is that quite often there are no initial value value in the database so I can't assign the dtp a value, other than a 'blind-date' (31/12/1899 etc...). Then when the user changes some of the data, I check to see if tha value of the dtp is the 'blind-date' and if so I don't save it. This all works fine except it looks crap and deseving. What I want to try and do is (I know I can do this with a Panel) try and over-ride some Paint method, and if the Date property is equal to the 'blaind-date' don't display any value i.e. make it blank. Is there any way to achive this without having to create my own custome VCL? Thanks in advance, K
