What key do you press in Edit1? Is this the return key? If so, if you change the focus from the OnKeypress event or OnKeyDown event, the actual key message arrives in the new focused control, i.e. AdvEdit and ReturnIsTab = true, this will move the focus to the next control. I'd suggest to use TAdvEdit instead of TEdit and adding custom code or add the code that changes focus in the OnKeyUp event.
1, Yes, Return key.
2, If I use AdvEdit / AdvEditBtn / AdvCombobox,... (no ReturnIsTab) instead of edit, the problem is stay.
The problem up about in TMS CP 126.96.36.199.
The OnKeyUp event usage solved the problem, but previously I use OnKeyDown for this without problem.
It is not recommended to force focus changing from events that are coupled to an underlying sequence of Windows messages. OnKeyUp is the safest place to change focus as it's the result of the last Windows message in the sequence WM_KEYDOWN -> WM_CHAR -> WM_KEYUP
I understand, not recommended.
But about until TMS CP 188.8.131.52 (and before some years) this work perfect, no problem.
That would be lovely, if the TMS controls more standardized. In this case more control's have ReturnIsTab property.
I think I started change the OnKeyDown events to OnKeyUp.
Thanks for all.
It's on the feature request list and being considered to add ReturnIsTab to more edit-style controls.
