custom formatting Crosstab

rbuser

Is there anyway (in code at runtime or IDE at design time)
to control the vertical spacing between rows in the
crosstab. I can change the font to make it smaller, but the
rows still retain quite a bit of white space between
themselves. I'd like to shrink the row height and get rid of
the "padding" if possible.

TIA,

The spacing is calculated internal to the crosstab renderer. You can create
a descendent crosstab renderer and register it over the default one. I was
hoping to suggest that you could override the CalcSpaceUsed method and
perform your own spacing calulations for the row heights, but there is no
setter method for the rowheights list. You may have to copy the code in the
ppCTRend unit for the crosstab renderer and save the TppCrossTabRenderer
class as TmyCustomCrosstabRenderer in its own unit. Change the class to
perform the spacing how you would like it. Search for the CalcSpaceUsed
method to start with. Then make a register call at the end of the unit to
register your new crosstab renderer.

Thanks Jim, I'll give that a try...

BTW, I'm using RB for the first time and "stumbled" across
the CrossTab component almost by accident. It seems to be
very powerful, but also, unfortunatley, very "unpolished"
and "bare-bones". How much attention will you guys be giving
it in the future in the way of enhancing it and surfacing
more of the functionality in a way that matches the ease of
use of the rest of RB?

Have you run through the extensive crosstab demos? They mainly show how to
change the formatting of the crosstab cells as they generate.

Yes, perhaps in a future version it would be a good idea to make it more
flexible.
