Hi,

I try to put VisibleExpression on a control in the data band, but I can't refer to the value of the field.
For example, if I type: 'A' = 'B' the expression works, but if I insert in the VisibleExpression the condition: [fieldname] = 'B' does not work. I get an error from EExprScanner which says: unknown character at pos 1: '['.
Can anyone tell me why?

(code typhon 6.8 with fpc 3.31 on windows 10)

Hi,

I have uploaded an example with the described case. I would like to be able to display / hide an image
based on the field retrieved (in this case 'Y' or 'N')

Hi,

I solved the problem!
In the VisibleExpr condition of the image control, instead of:

[APPROVED] = 'Y';

I put:

IF (APPROVED = 'Y', TRUE, FALSE)

and the report is created correctly.
