Hi!

Well, I also dived deep into the events firing related to page frames. The issue in my application was with grids and it was similar. But it was related to NOT firing the LostFocus event of the control inside of the grid.

The problem was that I made a grid similar to ListBox. So I used SET CURSOR ON/OFF to hide the text cursor when text field is focused. It worked ok till I switched to next page. On teh next page I observed strange thing - when textbox was focused inmy grid, and I switch to anotehr page, text cursor does not appear in the text boxes on next page. I started to dive deeper and determined that LostFocus of the grid control does not fire (I SET CURSOR ON there). The worse - that grid was a class in our framework (listbox-like grid class).

How I solved this problem? To workaroud this generically on a framework level, this was a kind of nightmare. First of all, I had to define code in UIEnable. In that event I call SetAll for special property. this assignment was catched by grids property _Assign method where I catch the moment where I need to SET CURSOR ON or OFF.

I see the same story is yours. All I recommend is to make this on the level of classes, otherwise you will require to add too much code to the form. I have no any recommendations to your case apart from my general experience. You can send me a form and I will try to look to it, if you have a time to prepare it for this.

Situation like "Catch a wind on a field". The one that cause sitting at office till 23:00 or all over the night... ;(((

>Say, user choosed S (Sales) first, typed info, ended on Seller1 field (required) and without leaving this field pressed F9 (save). FormValid was fired, suppose, there were no problems with this particular transaction and so data were saved and append blank was issued and the cursor is now back on the txtSource field. The user typed another S in the txtSource field and I move focus to the Page1.txtDate programmatically. However, this fires unwanted valid of the Seller1 textbox, since in order to set focus on another control I first need to leave focus from the current active control on the page.

>>I also go for option to use Cancel=.T. for button. It does not matter that field value changes are lost when user press ESC key - you will cancel anyway, and in most interfaces pressing cancel does not prompt user for confirmation. So, wonder why this is an issue?

>>In our framework we created special generic approach for this, but we did not dived so deep into generalizing things. We have a propery to specify Cancel button object location (starting from thisform object). Then we just had a generic method in the form class that using coordinates of mouse and coordinates of button determine if that button is pressed by mouse. Also, check for all other things like ESC or hotkey or whatever. Remember that Cancel button could go with image, as well as a hot key for it could be not always "C".
