Many thanks to Mike and Mark for helping me get my array and datagrid issues
resolved to date.
The latest issue is in calculations. I need to have calculations done in
floating numbers and then the array finishes calculating it truncates at the
6th decimal. I need to go out to at least E-23.
on mouseUp
get the dgdata of group "DGTester"
put it into tArray
put the keys of tArray
Repeat with x = 1 to 1249
put "3.76" into tArray[x]["usl_lcb"]
end Repeat
set the dgData of group "DGTester" to tArray
end mouseUp
putting a breakpoint at the end mouseUp shows that 3.76 was suc
Yep, what mark said. :) Sorry I wasn't as clear as I should have been.

If you then *put the keys of tArray[1]* you will see the
column keys, col1 and col2, so to get a specific cell is as you've been
trying to do with the dgtext tarray[1]["col1"] will get the data from row 1
col 1.
I do not get this behaviour. This only gives me the column keys, not column
keys

Forgot to mention, once you adjust the array you can then set the datagrid
to the new values by setting the dgdata of group "yourgrid" to tArray.
Depending on what you're doing, it may be more efficient to just update
values directly in the datagrid. Here are some base links to datagrid
lessons t
dgtext isn't an array value, to do what you want you need to get the dgdata
For example, if you have a simple table grid with 2 columns, col1 and col2
with 3 records, to get the array back out do
*get the dgdata of group "yourdatagridgroupname" *
*put it into tArray*
At this point, knowing whats
I have a datagrid of 1250 by 28 that has been successfully uploaded during the
creation of the datagrid.
I can use this line
put the dgText of group "DGTester" into tArray
to move the datagrid into an array. During debug process with breakpoint, this
is successful.
Now when I try to read, modi
