[Solved] fpspread: any method to make range address in order
«

I think there is a method/function that will change cell range from 'B3:A1' to 'A1:B3' but I could not find it. Any clue?
Thanks

There's no direct method available. You must use the formula parser to split the adress into parts and have it reassemble them:
Code: Pascal
[Select]
[+]
[-]
uses
fpsExprParser
;
function
FixCellRange
(
AWorksheet
:
TsWorksheet
;
ARangeStr
:
String
)
:
String
;
var
parser
:
TsSpreadsheetParser
;
begin
parser
:
=
TsSpreadsheetParser
.
Create
(
AWorksheet
)
;
try
parser
.
Expression
:
=
ARangeStr
;
Result
:
=
parser
.
Expression
;
finally
parser
.
Free
;
end
;
end
;
procedure
TForm1
.
Button1Click
(
Sender
:
TObject
)
;
begin
ShowMessage
(
FixCellRange
(
WorksheetGrid
.
Worksheet
,
'C3:A1'
)
)
;
end
;
I am not sure if this is working in the release version because I changed a lot with the formula parser recently.

yes. it works in trunk version.
I actually wrote my function as follows
Code: Pascal
[Select]
[+]
[-]
uses
fpsUtils
,
fpsTypes
;
function
FixCellRange
(
AN
:
string
)
:
string
;
var
cr
:
TsCellrange
;
procedure
Check
(
var
a
,
b
:
cardinal
)
;
var
ii
:
cardinal
;
begin
if
a > b
then
begin
ii
:
=
a
;
a
:
=
b
;
b
:
=
ii
end
;
end
;
begin
ParseCellRangeString
(
AN
,
cr
)
;
with
cr
do
begin
check
(
Col1
,
Col2
)
;
check
(
Row1
,
Row2
)
;
end
;
Result
:
=
GetCellRangeString
(
cr
)
;
end
;

Yes, of course. This is better because it does not require a worksheet
