Value of control in subform on mainform

SnoT

Hello,

I have a mainform with two subforms. (SubF1 and SubF2)
Both subforms are based on the same object and have a control called Ref.
On the mainform, I'd like to create a third subform that holds a filtered table, based on the two first subforms.

As a first step, I thought to do this by creating a variable that contains the necessary filter. (like = SubF1.Ref|SubF2.Ref ) but already there, I have problems to generate this value.

My question, though, is probably rather sipmle to answer : can I read information in a control on a subform towards a control on a mainform ?

Tnx in advance !

define a function on subforms's form that returns the value of your variable:

PROCEDURE GetMyValue@1() : Integer;
BEGIN
   EXIT(MySubFormsGlobalToPassToMainForm);
END;

Then you can call this function from main form using:

ValueFromSF1 := CurrForm.SubF1.FORM.GetMyValue;
ValueFromSF2 := CurrForm.SubF2.FORM.GetMyValue;

You can return only simple variable types.

If you want to return a complex variable types (like records) then you should change your function:
define a function on subforms's form that has a parameter called by reference. you don't need to use the return var.

PROCEDURE GetMyRec@1(VAR MyRecToPass 36);
BEGIN
   MyRecToPass := SubFormsRecToPass;
END;

Then you can call this function from main form using:

CurrForm.SubF1.FORM.GetMyRec(PassedRec1);
CurrForm.SubF2.FORM.GetMyRec(PassedRec2);
