uninumberedit onchange

[jahlxx]

Hi.

 

When I direct set a value to a uninumberedit, the onchange event don't raise.

 

If I tipe a velue, yes, but if I change its valur from code (ie.: x := 3), the event doesn't raise.

 

I forgot something?

 

Thanks.

Hi,

 

For now you can use this:

function dirtychange(sender, isDirty, eOpts)
{
   //
}

Best regards.

function dirtychange(sender, isDirty, eOpts)
{
   unilabel2.caption := 'Hello';
}

 

but reise an error.

Try:

function dirtychange(sender, isDirty, eOpts)
{
    sender.fireEvent("change", sender)
}

[jahlxx]

sorry, don't work.

 

I supouse that "change" is the is the onchange event of the uninumberedit, isn't it?

[jahlxx]

Sorry, but I can't make this to work ok.

 

I don't know why the onchange event doesn't raises.

 

Thanks.

Hi,

 

For now try to use this:

UniNumberEdit1.JSInterface.JSCall('setValue', [100]);

[Farshad Mohajeri]

sorry.

 

same result.

 

don't work

 

It should work in build 1352.

[Farshad Mohajeri]

OK I fixed it.

[jahlxx]

And in version 1....1360?

 

Thanks.

[jahlxx]

Yes, works.

 

Thanks.

I think that the changevalue event raises just before the value changes.

 

This behaviour, I think is not correct.

Hi,

 

Sorry, what do you mean? Can you explain how it should be ?!

 

Best regards.

I'm experiencing some extrange behaviour with this,

 

Attached is a sample project.

 

In the sample,works ok, but if you remove the UniNumberEdit1Change procedure, doesn't work as expected.

 

Thanks.

Hi,

 

Thanks for the test case, need to analyze...

 

But, of course, you can use one event hadler for two events for now:

procedure TMainForm.UniNumberEdit1Change(Sender: TObject);
begin
  Edit1.text := 'value ' + uninumberedit1.text;
end;

OnChange          -> UniNumberEdit1Change,

OnChangeValue -> UniNumberEdit1Change

If you remove UniNumberEdit1Change the events will not be sent to the server each time user presses a key. Changes will be available only when an event is generated on the client.

 

You don't need to use OnChangeEvent. Just put something like a OK button or APPLY button to get values from Form when user has finished editing.

[jahlxx]

Ok.

 

 

The only way to do this works as I need is put the necessary code in the onchangevalue of the component, and in the onchange event, put something. A blank commented line is enough.

 

With this (extrange for me), works ok, and the onchangevalue event works.

 

Thanks.

Why do you need to monitor changes on each key press?

[jahlxx]

For example, in a form, I type the customerId.

 

If the curtomerid changes, I have to query from the database the payment terms, default address, etc.

 

In vcl apps, I do this operation in the onchange event.

 

Here, with unigui, I do the the same, but with onchengevalue.
