I checked again Trevor. It makes sense that it does not work in
cases where
the controls are not cached - where it is broken is when the
controls are
cached but you try to get:
the dgRectOfIndex [1] of dataGrid
and the controls are scrolled heavily, so that the invisible row
view would
be above the top of the card. In these cases it does not return the
correct
geometry as the invisible row view is limited to the top of the
screen and
no its "true" negative y values. These means that if you try to
scroll to
the first row it does not work.
I just performed the following test and the dgRectOfIndex[1] returned
the proper result.
1) Created new Data Grid.
2) Changed style to "form"
3) Turned off fixed row height
4) Turned on "cache controls"
5) Turned off "persistent data"
6) Positioned Data Grid at 0,0
I then added about 50 or so lines to the Data Grid. Here are results:
put the dgRectOfIndex[1] of group 1
0,0,233,21
I then scrolled to the bottom of the Data Grid:
put the dgRectOfIndex[1] of group 1
0,-451,233,-430
I then tried scrolling the first index back into view and it worked:
dispatch "ScrollRectIntoView" to group 1 with the dgRectOfIndex[1] of
group 1
Just let me know what steps you are taking and what you are seeing. If
there is a bug that is the only way I can track it down.
