how do I check for a fieldvalue before the user has left the record in a page ?

NAV is new to me

I have a field that I want to check before the user leave the record. the field must not be empty.
I have tried with Error('something') but without look.

Try to Set NotBlank property as 'Yes' for the corresponding field.

Constraints -
If the NotBlank property is used on other fields than primary fields, the behavior is as follows:

• If the field is blank, and never entered, the page can be closed.
• If the field has been entered, and the user tries to enter a blank value, a validation error occurs

RockWithNAV

You can do what Sowkarthika suggested or else if you have certain conditions then you can write code on the QueryClose Trigger of the Page.

Note that if you use the OnQueryClose method suggested by RockWithNav then this won't work if the user moves off the record by going to the first/next/previous/last record instead of closing the page. You would also need to add code to the OnFind and OnNext methods too and check when the user navigates to a different record. You'd also need to handle the normal record navigation in those methods.
