I'm trying to use LiveBindings to format a number for display in a TEdit on a FireMonkey form.
I'm trying to use the Format method in the CustomFormat of the binding to format the number with two decimal places.
I can 'hard code' the output:
Format("Hello", %s)
which is working, but I can't work out what formatting string to use. If I try a standard formatting string such as,
Format("%.2f", %s)
I get a runtime error "Format invalid or incompatible with argument".
Indeed I get an error whenever I include a % symbol in the format string, so I'm guessing Format takes a different type of argument, but I can't find any documentation to say what the correct format string is.
You can not use Format('%.2f',[%s])
in LiveBindings -> CustomFormat
The %s is reserved for the data and for a TEdit , it's a string
d : double;
s : string;
...
d := 1234.5678;
s:=Format('%.2f',[d]);
Format() is to convert [int, decimal, double, float] to a string .
all other give you a error : invalid argument
valid is for example
TLinkControlToField1 -> CustomFormat : "Double : "+UpperCase(%s)
will give you in Edit1.text
Double : 1234.5678
OK , we know that Uppercase() for '1234.5678' has no effects .
Is only to show (%s) is a string
Solutions:
#00000.00
01234.57
1234.57
