Custom Component

[shawdown]

Hello, I am creating a custom component inherited from uniEdit.

In this component I would like to add a function in the ExtEvents KeyDown event.

 

What would be the correct way to do it?

Any suggestion.

Hi,

 

Sorry for delay,

 

Also you can use IUniJSInteface, for example:

JSAddListener('keydown', 'function(sender, e, eOpts){...}');

Delphi Developer, correct me if I am wrong but I assume he would need to add that call in the "WebCreate" method  which needs to be overridden in a custom component?

TCustomControl = class(TUniEdit)
protected
  procedure WebCreate; override;
end;

procedure TCustomControl.WebCreate;
begin
  inherited;
  JSAddListener('keydown', 'function(sender, e, eOpts){...}');
end;

Hello friends I added in the create event and it worked perfectly.

Having trouble using create?

 

constructor TCustomControl.Create(AOwner: TComponent);

Begin

  inherited;

  JSAddListener('keydown', 'function(sender, e, eOpts){...}');

End;

Lastly, what would be the way to add this code to a custom component?

 

 

[Sherzod]

JSConfig('remoteSort', [False], DataStore);

 

[shawdown]

JSConfig('remoteSort', [False], DataStore);

 

Perfect.

Thank you one more time.

Hi,

I want to put a javascript encapsulate on a customDateTimePicker.

function afterrender(sender, eOpts) {
$("#"+sender.inputEl.id).inputmask("99/99/9999",{placeholder:"__/__/____"});

I'm trying to add the method on WebCreate but it give me error 'There is no Default JavaScript Object. [ : TUniSmDateTimePicker]'.

If I put it in LoadCompleted, it doesn't work.

Is there any other method to add the listener that could be encapsulate?

Also you can use ClientEvents.

I already use ClientEvents but I would like to encapsulate my method.

Which method ClientEvents is loaded? Is there a way to override it?
