Hi Steve, hi guys,
first of all thank you very much for this wonderful piece of software.

My problem: in a new record form sometimes i need to overwrite the default value for several fields with an arbitrary content.
Let's say I have a table 'customers' with fields defined as

[field1]
Default = ""

[field2]
Default = ""

Under some circumstances I need something like this delegate class:


class tables_customers {
    function block__before_new_record_form(){
		if (*something happens*) {
			the_value_of_field_customer_field1 = "abc";
			the_value_of_field_customer_field2 = "xyz";
		}
}

then show the form as usual, letting the user to change those values before saving the new record.

I can't figure out how to set those field values.

Thank you in advance for any suggestions.
Regards, Carlo

OK.. you can do this in a couple of different ways.

1. In the delegate class you can define methods of the form %fieldname%__default() which will return the default value for that field.ÃŠ This way you can do some logic in this method to produce a different default value under different circumstances.ÃŠ (This is the best way to do it).

2. Using javascript.ÃŠ Add some javascript in a block like "after_new_record_form" that actually sets the default values.ÃŠ (This isn't' as good IMHO).
