Trevor,
Summary
Thank you for the explanation! I am trying some variations on your
suggestion. The code for the repeat loop that will do the deletion is
not within the behavior script for the data grid, so I cannot use the
syntax as suggested "of me", right? The code is part of a menu choice
so it's in the menu button script. I am trying to refer to the data
grid by it's name but do not have the syntax correct. I can't find an
example. Details follow.
More Details
Context
Haven't gotten it working yet, perhaps due to misunderstanding of
syntax, or use of the getdataofindex command,
or where it can be used. The API manual says
GetDataOfIndex
- GetDataOfIndex (pIndex, pKey)
- Retrieves the internal array for key pIndex of the internal array in
the data grid. If pKey is empty
then the array associated with key pIndex in the internal data array
will be returned. If pKey is not
empty then the value of that key for key pIndex of the internal data
array will be returned.
When I put the following code in the message box, it works
repeat for each item theIndex in the dgIndexes of group "data grid 1" of
card "data grid card"
answer theIndex
end repeat
When I add a line to call getdataofindex (and the grid is not empty in
column 2, fyi, I think of it as row = index, key = column)
repeat for each item theIndex in the dgIndexes of group "data grid 1" of
card "data grid card"
answer theIndex
if GetDataOfIndex(theIndex, "col 2") is not empty then
answer "not empty"
end if
end repeat
then the first answer command works, but it never gets to the 2nd one,
in trying to execute the if statement there is an error message
Message execution error:
Error description: Function: error in function handler
If I change it to refer specifically to the grid, like this
repeat for each item theIndex in the dgIndexes of group "data grid 1" of
card "data grid card"
answer theIndex
if GetDataOfIndex(theIndex, "col 2") of group "data grid 1" of card
"data grid card" is not empty then
answer "not empty"
end if
end repeat
then there is a syntax error
Script compile error:
Error description: if: missing 'then'
Can you enlighten me as to syntax that would work? Or what I am doing
wrong?
Thank you again,
Sadhu
