Validating in form extension without datasources

Posted on by Community Member

Hello , I need to validate a create form without datasources.

Validating is based on 2 FormControls from EcoResProductCreate form.

1. formControlStr(EcoResProductCreate, Types_ProductType)

2. formControlStr(EcoResProductCreate, SalesPrice)

For validating I take event handler in extension class but I dont know how to extract and interact with FormControls without datasources.

    [FormControlEventHandler(formControlStr(EcoResProductCreate, Types_ProductType), FormControlEventType::Validating)]
    public static void Types_ProductType_OnValidating(FormControl sender, FormControlEventArgs e)
    {
        FormControl fc = element.design().controlName(Types_ProductType);
        var args = e as FormControlEventArgs;
        boolean ret;

        ret = checkFailed('%1',fc.text());
        args.cancel(ret );
    }

    [FormControlEventHandler(formControlStr(EcoResProductCreate, SalesPrice), FormControlEventType::Validating)]
    public static void SalesPrice_OnValidating(FormControl sender, FormControlEventArgs e)
    {


    }

(I was trying some advice from web)

? How can I get Value from Form Controls and return checkFailed properly ?

Hi dreed,

For your scenario you can use COC instead of event handlers.

Thanks,

I think you should hook into onValidated event, so that your code runs after the standard validation.

You can check this example to understand how to set the return value of the validation (it's about a validateWrite event on a table, so there's some homework for you to apply it to your scenario): d365solution.blogspot.com/.../validatedwrite-eventhandler-d365-at.html

I also warmly recommend Chain of Command if you want to avoid confusion, since it's much simpler and less confusing than events :)

I would also use COC but if you are going to do it with eventHandler you can try something like below. (This is a solution I haven't tried myself, I got it from the link below.)

The situation in the link is slightly different but I hope the parmValidateResult will do the trick

[FormControlEventHandler(formControlStr(EcoResProductCreate, Types_ProductType), FormControlEventType::Validating)] public static void Types_ProductType_OnValidating(FormControl sender, FormControlEventArgs e) { FormControl fc = element.design().controlName(Types_ProductType); var args = e as ValidateEventArgs; boolean result = args.parmValidateResult(); if(..control..) { result = checkFailed('%1',fc.text()); } args.parmValidateResult(result); }

Yes, that's when the "homework" that I mentioned comes into play :)

Reading your first post again, I think you actually don't even have any problems in the validation itself (set true/false based on a condition). Am I correct? But you don't know how to read the value of the form control?
