Use of Property "Editing" in Pages using C/AL Code.

Posted on by Community Member

Hello All,

I need help with the following:

In Dynamics Nav 2013, I have a Page type CardPart, where I have set a source table to manage data, on page I added the fields from that table. I do some field validations using C/AL Code, with respect to enable editing in a field if the condition introduced in a previous field is met and if is not met I want to disable the field.

I tried to do, in the following ways:

Field.Editing(FALSE);
CurrPage.Field.Editing(FALSE);

However, in both ways I get the following error:

---------------------------

Microsoft Dynamics NAV Development Environment

---------------------------

You have specified an unknown variable.

Editing

Define the Variable under 'Global C / AL symbols'.

---------------------------

Could anyone tell me how can I?.

Best regards,

Marlon T. Ramirez

I think you need to use the EDITABLE property instead of the EDITING one.

Use the C/AL Symbol menu to find out :)

In C / AL code I can not make a field editable property.

And yes you're right, I was wrong the truth the right word is editable, but even so I can not use it, because said property I can not not even see in the C / AL Symbol Menu, this only appears for the page, but the page I do not want setting it but only the field or control that I specify. :)

Hi

Yes it is not possible to change only a field to editable,

Rather what you need to do is to set the "On Validate" code of the field in the form or page to check if it is allowed to be edited then generate an error if not, the error will cause the system to empty the field again

Field - on validate()

IF Rec.OtherField = '' THEN

ERROR('you cannot fill in this field if the other one is blank');

Hope this makes sense

Take a boolean variable (ex: fieldeditable)

set it to false in the begining of the onOpen page

Based on the your first field validation, change it to true

set the boolean in second field editable property..

Dear Mohana,

I created a Boolean variable named EditarSucursalInv in the C/AL Global.

Then I added to the property "Editing" of my control.

After initialize the variable in Event "OnInit()" of the Page.

And finally reassign the variable in Event "OnValidate()" of the field that triggers the validation of editing changes.

Only that's what I did, but it does not work, because although disabled the field, since the code that I put in the Event "OnInit ()", was executed, but it when running the Event "OnValidate ()" is not generates unchanged, that is, it is always disabled.

Could you to send me an example with Nav controls, how would you?

Best regards,

Marlon T. Ramirez

Are you sure this works Mohana?

Hi Marlon,

It can be done very easy. You do not use Editable - but Enabled.

On the fields you want to be editable, you make the enabled depending on a Boolean value.

This boolean you control both from OnOpenPage, and later from the validate on the different fields.
I suggest you make a function you call with the FieldNo each time, so you keep it all centralized and the code clean.
On OpenPage you call the function with a 0 (zero), which in the function will process all the fields.

You can see an excellent example on this on the standard Item Card.

Kind regards

One small thing. When you declare the boolean variable, don't forget to set the property IncludeInDataset to Yes. Otherwise, you'll get an error because the program can't find the variable.

Yes this surely works, for an example look at page 21 customer card, how ActivateFields function is used for contact no. fields.

Hi Neville,

It works, you are to ensure that the "IncludeInDataset" property is set to True.
