How to check, if a DBImage (or it's DataField) has a picture loaded or not

rbuser · February 2010

Hello,
as the title says, I would like to know, how I can check in RAP, if a
DBImage (or it's DataField) has a picture loaded or not.
I need to know that, so I can set it to visible or invisible. The DBImage is
placed on the detail band and has a certain size (AutoSize = false) and if
there is no picture, that size shouldn't stay "reserved" for the DBImage,
i.e. the height of the current detail "entry" should become smaller and not
have the "max" height, which would be the same as the DBImage height.

All attempts I made were not successfull... How can I achieve that in RAP?

Regards,
Mark

Hi Nico,
works just fine now, thank you very much.

For some reason the WiKi-search doesn't return any results to "IsNull", so I
wasn't able to find anything about it that way...
