Hi,
I’m sure I’ve spotted the solution for this, I saw something mentioned in a code snippet somewhere that I suspect is the fix … but can’t recall what/where!
I have a UserControl placed on a TabPage in the parent form. It is on the second tab and therefore not displayed when the form loads.
The parent form has a student selection list. Prior to student selection I don’t want any interaction on the UserControl, so this.Enabled = false at design time, and then “public void LoadFees(ApplicationService service, CourseEnrolment enrolment) => [SNIPPED] this.Enabled = true;” is called when a student is selected.
If the tab is selected (so the UserControl is visible) prior to selecting a student, all works as expected, however if the student is selected then the tab is selected, the UserControl is still disabled.
Can you advise?
Cheers,
Neil
Can’t reproduce. I added a TabControl with 2 pages, added a UserControl on each page with a child button and Enabled = false at design time. It shows the buttons as disabled since the parent UserControl is disabled. Then I have a button that sets Enabled=true on both UserControl in both tabs. In any possible sequence settings Enabled=true works.
Can you attach a small test case?
