Dear All

How can i get reference of any controls of Form at class level.

For example--: On standard Axapta Application SalesTable Form having the
post button on the SalesTable Form Header i can get the absolute path of this
control through the right-click to the control it self and go to
Add-Ins-Copy-Entire Path through this i can got following absolute path:

\Forms\SalesTable\Designs\Design\[Group:Table]\[ButtonGroup:ButtonsHeader]\[MenuButton:ButtonHeaderUpdate]

Axapta application programming having any standard method through which we
can get reference of sepecific path.

Hi Manish

Do you need a handle to the a specific control on a form?

If yes, that's easy:

// direct access with name
FormButtonControl formControl;
;
formControl = formRun.design.controlName('myButtonControl');
formControl.visible(false); // modify a property


// or loop all controls
FormControl formControl;


getAllControlsInside(Object _obj)
{
int i;
;
if (classIdGet(obj) == classnum(FormDesign) || // only container
controls, may be there are some more ...
classIdGet(obj) == classnum(FormGroupControl) ||
classIdGet(obj) == classnum(FormButtonControl) ||
classIdGet(obj) == classnum(FormTabControl) ||
classIdGet(obj) == classnum(FormTabPageControl))
{

for (i = 1; i <= formRun.design().controlCount(); i++)
{
formControl = formRun.design.controlName('myButtonControl');
info(formControl.name());
getAllControlsInside(formControl);
}
}
}
;
getAllControlsInside(formRun.design());


If I was going wrong, please let me know what else your desire is ;-)
Best regards
Patrick

PS: the code snippet was written direct in this forum so it could contain
some little bugs.

Or a bit more generic

public static void listControls(FormRun formRun)
{
int level;

boolean hasMethod(Object obj, identifierName methodName)
{
return new SysDictClass(classidget(obj)).isMethodActual(methodName);
}

str objectType(Object obj)
{
return new SysDictClass(classidget(obj)).name();
}

void GetChildControls(Object control)
{
int ctrlNum;
FormControl childControl;
Object childControlObj; // for Axapta "casting by assigning"
;
// those methods should be on every container control, but we want to be sure
// (there should actually be a father class (or better an interface) for all of them,
// exposing those methods)
if (hasMethod(control, 'controlCount') && hasMethod(control, 'controlNum'))
{
level++;
for (ctrlNum = 1; ctrlNum <= control.controlCount(); ctrlNum++)
{
childControl = control.controlNum(ctrlNum);
info(strfmt('%1%2 (%3)', strrep(' ', level * 3), childControl.name(),
objectType(childControl)));

childControlObj = childControl;
if (hasMethod(childControl, 'isContainer') && childControlObj.isContainer())
{
GetChildControls(childControl);
}
}
level--;
}
}
;
info(formRun.name());
GetChildControls(formRun.design());
}

You can call this from inside a form passing element or like this

Args args = new Args(formstr(InventTable));
FormRun formRun = new ClassFactory().formRunClass(args);
;
formRun.init();
CbsTools::listControls(formRun);

hi Luegisdorf !

Thanx Luegisdorf to sending this ,but this code is no working on
class level.
I want to access any specific control on any method of class but this code
is not working on class level.

I am writting following code on class method:

void AccesFormControl(FormRun formRun)
{
FormButtonControl formControl;
;

formControl = formRun.design().controlName("ButtonToggelSimple");
formControl.visible(false);

}

and i'm call this method from the run method of "Purch table" like this:

void run()
{
Args args = new Args(formstr(PurchTable));
FormRun formRun = new ClassFactory().formRunClass(args);
;
super();

MenuButtonApprover.enabled(false); // USR-Modification on 08 Nov 2005 by
E-297

if (!advanced)
TabHeader.tab(2);
else
TabHeader.tab(1);

eis297_Approve.AccesFormControl(formrun); // method called here


}
But these code sequence flashing the error messge "Formdesign object not
initilized" .

Can u do some thing in situation?

If u have solution for this problem plz revert me back as soon as possible.



Thanks & regards

Hi E-297,

formRun.design.controlName('ControlName') is a correct way of accesing a form control. This has
nothing to do with class level (whatever you mean by this).
The FormDesign is not initialized in your code because you did not call init on the FormRun object
you were creating. Anyway if you want to change controls on the PurchTable form, from which you are
calling your method, you should pass this FormRun to your method through the element keyword
(eis297_Approve.AccesFormControl(element))instead of creating a new FormRun.
