Just a thought on this, but I get the impression that this doesn't work if you set the content and then call it. I suspect this is because the DOM hasn't been updated yet, and so there is nothing to select, or it gets cleared. But I have an OnEnter which changes the text (when not in, it shows values with things like currency or percent signs, when editing, it removes them and goes full precision) and SelectAll doesn't work. But doing edit.SelectStart := 0; edit.SelectEnd := Length(myContent); works fine.

SelectAll does exactly that:

procedure TInputElement.SelectAll;
begin
  if (Self=InterfaceManager.ActiveElement) then
     THTMLInputElement(DOMElement).setSelectionRange(0,Length(InputValue));
end;

However, you'll notice that it does a check on the focused element first.  That may be what is tripping you up, but I would have to investigate this further to be sure.

Hah! I didn't click the further call when I chased it down as I presumed it was a "native DOM" thing. I suspect that you are right in the focus issue - OnEnter may not know it is the new focus I guess.
Is there a reason it can't select all for anything? Why can't I selectAll in a hundred edits at the same time?

It actually *is* a native DOM thing - an input element must have focus before you can manipulate the selection ranges for the input element.

I can't reproduce what you're seeing here.  I'm doing this:

procedure TForm1.Edit1Enter(Sender: TObject);
begin
  Edit1.Text:='Hello World';
  Edit1.SelectAll;
end;

and it works fine, selecting all of the text.

If you want to send me something more specific, I can test it out here and see what's going on.

Hmm, okay, I will dig into it further.
