|Image within Grid|

Just started investigating EWB. Can a grid column be used to display an icon or small graphic for status purposes? Thanks!

I believe not at this point. EWB 2 may do, but that isn't here today.
FWIW, I have done a lot of "semi-grids" and I just create a master TPanel populated
with the controls I want, and then replicate it "manually" for each entry in the
table. You can sort of see an example at https://dev.banxia.com/ which is not at
all finished as an application, but the store items are created at run-time with
data from the server. The cart is a similar list of items.

Thanks for the reply. Most of my datasets are around 100 records. I wonder what that would be like performance wise.
Has there been a "ballpark" release date on 2.0?

I think you could do some sensible optimisations to make 100 "panel rows" quite
viable. Create those that are needed immediately for display, and then create the
rest on a timer.
Ballpark on 2.0 is "when it is ready". Tim is working on it among other things, but
being programmers we know how things go.

That should be fine, for now. The biggest issues with the grid, currently,
are the styling limitations and the fact that the grid is not "virtual".
IOW, if you have 1000 rows and 10 columns, then it will create 10,000 cells
to hold everything. EWB 2.0 will have a virtual grid, so that 1000 rows and
10 columns will create N visible rows x the number of columns. The big
hold-up with doing this in 1.x was the fact that it requires custom
scrollbars. EWB 2.0 uses nothing but custom scrollbars in order to support
things like transparency, etc.

ASAP, is about all I can say at this point. I'll have more information as
soon as the form designer overhaul is finished, which should be soon.
