UniLabel txtHTML height

[JDDEV]

Hi all,

I have an uniLabel with AutoSize=True and textConversion=txtHTML

The default height is 23 and at runtime i put Caption:='Line1<br>Line2';

The height is still 23. I hoped 46 !

Does exist a function to get the height of a Html text ?

Thank you.

Sorry, for what purpose?

The UniLabel has got an UniSimplePanel for parent.

The UniLabel is align on top to the UniSimplePanel.

At run time when i change UniLabel.Caption (with html tags), i would like to autosize UniSimplePanel synchronized with the new Unilabel content height.

No solution for that ?

Hello,

On the server side?

Yes on the server side.

It is to optimize a custom message form size

You can try this approach:

1. UniLabel1.ClientEvents.ExtEvents ->

function resize(sender, width, height, oldWidth, oldHeight, eOpts)
{
    ajaxRequest(sender, '_change', {height: height})
}

2. UniLabel -> OnAjaxEvent

procedure TMainForm.UniLabel1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = '_change' then
    (Sender as TUniLabel).Height := Params.Values['height'].ToInteger

end;
