Enable/Disable Menu Items in Menu Button

sanjeevasawale · 2006-03-27

Friends,

I searched for the solution but couldn't get.

Actually, I wanted disable one Menu Item in Menu Button based on some condition.

Can this be done. I can do other way round that is, write code in that menu item to restrict its functionality.

Please guid better way.

Thx,

Sanjeev

Hi,

Do one thing. make another menu button(MB2) and make the menu item disable (which u want to disable by making visible to No). put this menu button on ur previos menu button(MB1). now add following line of code to OnOpen Form:

if <Condition> Then begin
Currform.MB1.visible := False;
Currform.MB2.visible := True;
end
else begin
Currform.MB1.visible := true;
Currform.MB2.visible := false;
end;

Regards,
Gaurav

Assign a value to the Name property of a command or menu button then you can dynamically set the Enabled or Visible properties of the control in the trigger code using C/AL commands.

For example, to disable a menu button that has the value of the Name property set to btnCustomer, you would use the following command:

CurrForm.btnCustomer.ENABLED(FALSE);

Unfortunately, there is not a method to dynamically control the individual menu items of a menu button. However, it would be possible to create two different menu buttons with different Name property values. These two button controls could then be stacked on top of each other and trigger code added to the form to make one button visible and one button not visible, based upon the desired criteria.

For example, to control which menu button is displayed, based on the existence of a customer email address, where the button controls were named btnCustomer1 and btnCustomer2, you would use the following code in the OnAfterGetCurrRecord trigger:

IF "E-Mail" = '' THEN BEGIN
CurrForm.btnCustomer1.VISIBLE(TRUE);
CurrForm.btnCustomer2.VISIBLE(FALSE);
END ELSE BEGIN
CurrForm.btnCustomer1.VISIBLE(FALSE);
CurrForm.btnCustomer2.VISIBLE(TRUE);
END;

Friends,

I feel u didnt get my problem. I wanted to enable/disable the Menu Item in Menu Button and not Menu Button. I know menu button can be enabled/disabled. I wanted to enable/disable the 1 or more Menu Items in Menu Button.

Dear Gaurav,

Thx for ur efforts of putting it again. Your suggestion will work only when it will be only 1 or 2 conditions. But think the case where for different reasons (multiple conditions) will be there then I can not have multiple buttons. I should be able to simply enable/disable the items based on multiple conditions.

for example:
condition 1 will disable menu item 2
condition 2 will disable menu item 5
condition 3 will disable menu item 8
condition 4 will disable menu item 10

I hope u got what I mean to say.

We should all be able to simply enable/disable individual menuitems ... but we can't. It is so by design.
I think you have to live with it. Sorry

... but you can't, it is simply not possible in Navision. You can ask the same question multiple times, but the fact remains that it is not possible.

If you want something that looks like a dynamic menubutton you will have to use the trick posted by Guarav.

Do I hear an echo ;-)

Hey Black ?,

U got it wrong. M not under estimating anyone or thinking people are fool here. I thought people miss-understood my query so written it again.

Try this

Not exactly you want but ...

Trigger onPush of ComandButton

var bool1,bool2,bool3 - boolean - or your conditions
var OptionString, NewString - text 250

OptionString:='';

IF bool1 THEN
  IF OptionString='' THEN
    OptionString:='menu 1'
  ELSE
    OptionString:=OptionString+',menu 1';
IF bool2 THEN
  IF OptionString='' THEN
    OptionString:='menu 2'
  ELSE
    OptionString:=OptionString+',menu 2';
IF bool3 THEN
  IF OptionString='' THEN
    OptionString:='menu 3'
  ELSE
    OptionString:=OptionString+',menu 3';

NewString := SELECTSTR(STRMENU(OptionString),OptionString);

CASE NewString OF
  'menu 1':BEGIN
    MESSAGE('Menu 1 action. May be open list form');
  END;
  'menu 2':BEGIN
    MESSAGE('Menu 2 action.');
  END;
  'menu 3':BEGIN
    MESSAGE('Menu 3 action.');
  END;
END;

I'm not sure exactly what you are looking for but it sounds like you want to disable menu items for certain users which sounds like security to me.

A post was made a while ago about security roles and how the ones from Microsoft don't seem to work. A idea was put forth that you should start out with giving the users everything. Not just Table/Form/Report 0, but list every table/form/report/codeunit/etc by number and granting permissions. Then as you want to restrict users and tighten security you take away the permissions from all users and create a new group of users that have these permissions.

I was testing this out and found it works very well, especially if you just remove permissions for the forms they have no need to see.

(And now I get to the point!)

If what you are trying to do is not allow the users to see a form/report/dataport all you have to do is take away their permission to view that object and they cannot see it in the Menu. This makes their security the condition and it does it automatically without extra coding. If their security changes in the future to allow them that object then it will be back on their menu.

Of course it is a little more involved to set up but it does tighten security a lot in the process and who doesn't want that?

Hopefully this helps,

Joe
