Hi All,
For a project specific reason, I'm trying to create views by code in different B4XPages. Everything works ok except the fact that I can't catch the Click event on the correct page.
I've created a zip file of a project demonstrating the issue.
Basically I've MainPage and Page2 (two pages). Each page have a button that switch from MainPage to Page2 and vice-versa.
When we enter Page2, two buttons are created, one in MainPage and other in Page2. They're well created because when we navigate to both pages, we see them created. I'm creating one button in MainPage and another in Page2 (when I enter Page2) using this code:
I had to make Root from MainPage Public so I can access it from Page2 to add the button to it.
Now, my problem begins.
I've this in MainPage:
And this in Page2:
I was expecting that when I press the button in page1 I would see the page1_Click event being raised from MainPage and when I clicked on the button in the second page I would see the event page2_Click in page2 being fired. That doesn't happen. If I add this to Page2:
I'll see that this event is fired in Page2 event after I've added it to the Root B4XView of MainPage.
Is there any way I can achieve this? I mean, create the views in the correct page and make the events to be fired on the page I've created them?
This is a very specific issue but I hope any advanced users might have the knowledge to help me out...
Thanks in advance.
