==============

Usually in Dialog Forms it's unable to set mandatory property for Dialog Fields. The lack of this property sometimes annoyed me. At the end I've decided to eliminate this gap :-)

To expand the standard functionality you need to do the following steps:

1.Add mandatory() method into DialogField class:

// Created by GRR on 01.11.2005
void mandatory(boolean r)
{
    str name;
    // If properties exists then we are on server
    if (properties)
    {
        name = #Propertymandatory;
        if (! properties.exists(name))
            properties.add(name,true);
        properties.value(name,r);
    }
    else
        this.fieldControl().mandatory(r);
}

2. Add into unpack() method following lines:

case #PropertyMandatory:
    this.mandatory(unpackedProperties.valueIndex(i));
    break;

Now you may enjoy mandatory property in Dialog Forms.

This trick published in Axaptapedia too.

Здесь следует учитывать вот это

Цитата:

Mandatory property starts working only after a value is entered into the control. What this means is that if you simply press OK right after the dialog is opened, you won't receive an error (regular forms works this way too)
