Access Objects..

Gchamm

Hi,
Im a newbie.. Ive created a form, that I want to populate with data. I've added some variables, and I can populate, then print the form. Im not using any bands, but just a simple form..

Anyway, I have some check boxes i the form.. From code, I want to turn the check boxes on or off. I for the life of me cant figure out how to access those properties from code. Can someone help??

What I mean by a form , is a business form, that will be populated with real time data.. then printed.

use the obp event of the checkbox
ie
procedure CheckBox1OnBeforePrint(Sender: TfrxComponent);
begin
checkbox1.checked := <My Variable 1> = 20;
end;
this example assumed "my variable 1" was added to the variables list and given a value either when created or using the set method somewhere in report code.
or
you can also use an onbefore print event of the report component to retrieve a value from delphi
ie
if sender.name = 'CheckBox1' then
tfrCheckboxview(sender).checked := some boolean value.

Thanks, I think that helps.. But Ive got about 40 check boxes that I'd like to do all at once.. I.E. Reset them all to unchecked.. I guess Id have to build a large "if then" structure to do that huh?

depending on where you do it from
you can iterate through all the objects and set their values
either from just after loading the report in delphi and using the findobject method
or internally
in obp of page

var
i: Integer;
c: TObject;
begin
for i := 0 to Sender.Objects.Count - 1 do
begin
c := Sender.Objects
if c is TfrxCheckboxView then
TfrxCheckboxView©.Visible := False;
end;
end;

TfrxCheckboxView?©.Visible := False;
should have read
TfrxCheckboxView( C ).Visible := False;
