>I have some code, which is repeated in all grid columns in most grids all over the application. In trying to centralize this, to have the code in a single place (and, especially, not having to call a special program every time I add a grid column!), I experimented with BindEvent(). The code contains This. and ThisForm., which I managed to translate.

Interestingly I have the very similar problem now and I'm trying to figure out a good solution.

I have a pageframe on the form. I want to be able to detect changes and prevent user from leaving the page if there are changes done.

I can write a code in Page.Deactivate:

If changes were made and user answer Cancel on the question 'Do you want to save changes?'
there should be NODEFAULT in the page.Deactivate.

Now, since there is exact same code in all pages, it will be nice to bind them to form's custom method. However, how do I prevent users to leave the page using this technique?

Thanks in advance.
