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 ?

Try this:

FormControlCancelEventArgs eventArgs = e as FormControlCancelEventArgs; info("not valid!"); eventArgs.cancel(true);

I fixed my code 1-2 minutes after posting (I forgot to fix it while I was copy-pasting your code). I think you got it without me correcting it.

But it seems like the problem is using values. You can get the value of the other control as you did first control, just be careful with its type.

But how can I take another FormControl from same form. Because for my validations rules I need both of values of FormControls to do validation. If I take this from sender how can I take another formControlStr(EcoResProductCreate, SalesPrice) form control value.

You have the form control in the "sender" parameter of the event handler method.

You need to cast it to a correct type, something like this:

[FormControlEventHandler(formControlStr(EcoResProductCreate, Types_ProductType), FormControlEventType::Validating)] public static void Types_ProductType_OnValidating(FormControl sender, FormControlEventArgs e) { FormComboBoxControl productTypeControl = sender as FormComboBoxControl; EcoResProductType productType = productTypeControl.selection(); info(strFmt("%1", productType)); }

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?
