Desktop HTMLFrame - Script Updated At Runtime - How Can We Force Scroll-To-Top via code ?

[andyhill]

Subject to user interaction we change the contents of a HTMLFrame (our frame has a pre-specified height):-

BeginUpdate
Clear

script

EndUpdate

The previous contents were many many lines long forcing the user to scroll to bottom, now that we have new contents I want to reposition to the top.

How Can We Force Scroll-To-Top in code ?

Hi,

Sorry, do you have a simple testcase to see the "problem"!?

Set Flag in Server Module BeforeInit to suit (we have multiple frameworks).

As stated above clearly, I need to scroll to the top of the HTMLFrame via code at runtime after script update.

Hi,

In your case:

procedure TMainForm.UniHTMLFrame1UpdateHtml(Sender: TObject);
begin
  UniPanel2.JSInterface.JSCall('body.setScrollTop', [0]);
end;
