Greetings!

I have a form that uses a combo box to enable/disable a button, depending on
the content of the combo box. I overrode the modified() method to call my
method InitButton() which does the actual button.enabled( false ) call. I do
a selection on the combo box, and the button is enabled/disabled. So far. so
good.

However, the combo box is a bound control, and even though I call
initButton() in my form's init() method, the button is not enabled/disabled
correctly based on the combo box data fetched from the datasource. When I do
a selection, though, it does what it is supposed to. As I mentioned, both the
combobox modified() and form init() method both call initButton().

Any idea why loading the data does not initialize the button?

Why is the value of the combobox.selection() always 0?

Here is my code:

in the form:
public void init()
{
super();
element.initButtonA();
}

in the combo box:
public boolean modified()
{
boolean ret;

ret = super();
element.initButtonA();
return ret;
}

void initButtonA()
{
if ( cmb.selection() == Enum1::Value1 )
buttonA.enabled( true );
else
buttonA.enabled( false );
}

Thanks!

Hi,

You need to override a method active() on datasource. In this method after
super() just call this method.
Actually when ever you change a record the button should work according to
the value in that record.

Thanks for the suggestion. However, nothing has changed.

Here is what I did.

in the form data source:
public int active()
{
int ret;

ret = super();
element.initButtonA();

return ret;
}

Is this what you suggested?

The enabling/disabling works when the combo box is modified, but not on the
initial activation of the form.
It seems that the combo.selection() always = 0 on startup, regardless of the
actual data from the datasource that is loaded into the combo box , hence the
button is always disabled (i set the button disabled when enum value = 0)

I would appreciate more suggestions/insights. Thanks.

Hi,

Then I think cmb is a form control name. As you said that it is bound
control, then it will be better to take it as table's field. Do it like this:

void initButtonA()
{
if ( Table.ComboField == Enum1::Value1 )
buttonA.enabled( true );
else
buttonA.enabled( false );
}

Also call the same method from modified() method on Data Source -> field ->
ComboField.

Also no need to call initButtonA() from form - init().

Thanks! You hit the nail on the head.

Moving the enable/disable method call to the active() method instead of the
init() method was the difference.

Thank you so much.

Dear PacMan,
For this you need to write code on two places:

1. Datasoources>>TableName>>FieldName>>Modified()
2. Datasources>>TableName>>Methods>> active()

I had written these few lines on both the places:

if(eisTransportTable.eisTestEnum == eisTestEnum::ValueOne)
myBtn.enabled(true);
else
myBtn.enabled(false);
