In my program I have the main window in the background which has a smaller, UIScrollView on it. I have buttons on each page of the scroll view which I want to bring up a modal view that can be dissmissed. It works fine for the first page, however, when I click the button on the second page of the scroll view the modal view that is brought up is on top of the first page instead of the second and the second page is completely blank. When I close the modal view, the first page has been replaced with the second page and the second page is still left blank... The code I am using is:
MVC = new NewsModalViewController(this);
MVC.ModalTransitionStyle = UIModalTransitionStyle.CoverVertical;
MVC.ModalPresentationStyle = UIModalPresentationStyle.CurrentContext;
I've been trying to play around with the frames but having no luck...
Any insights?
Cheers
I would rewrite the subpages to fire an event that the parent view listens to. Then, display the modal from the parent view (you can actually create the modal in the child view and pass it up on the event). This eliminates any problems with the modal being applied to the wrong context.
There may be another explanation, but this is the method I've implemented on a couple applications and has served me well. It appears that modals are best displayed only from the highest level view in the stack.

I have used Fresh MVMM. I need to pass a data from one page model to another page model without using init and reverse init.
Eg: I have one toggle button in first content page.
I need to toggled the button based on the selection in second popup page without popup the second PopPopupPageModel.
ReverseInit is worked when popup the second PopPopupPageModel and can easily pass data.
But I need to toogled the button in first page without popup the second page.
Please help...
I am working on a xamarin forms project which have a carousel page container, and content pages as its children are created dynamically on different condition checks. (Minimum 8 children in my case)
Let's take the mentioned minimum case. I enter some values in entry/picker controls in the 1st child and then navigate/swipe pages till 5th child. When I came back to the first child page, the values I entered/selected are now vanished/refreshed.
I have noticed that carousel page saves only 3 pages data in it. i.e. (Left Page, Current Page and the Right Page).
And Tabbed page saves 4 pages data.
I want the values to stay in the child page where I entered whether I navigate to the last most page or in the middle and navigate back to that page.
I have googled via the letters as "Carousel page/ Tabbed page Saved states" etc. but unable to find something useful.
So, I need to know the property name/ method name etc. by which xamarin forms setting the limit of carousel page as 3 and tabbed page as 4.
Waiting for your response.
Thanks.
OK I found that I was using a Custom Picker Control and the value refreshing issue is with it. I just forget to set the selectedIndex of the picker on OnElementChanged event.
I have a situation where a toolbar item in CKEditor5 opens a ContextualBalloon which contains an iframe.
In my current understanding, the only way to hide the balloon is to remove the iframe view i.e.
this.balloon.remove(this.colorPickerIframeView)
However this removes the iframe view from the DOM, meaning that the next time I open the balloon view the iframe is reloaded.
I'd rather not have to reload the iframe every time, is there any way around that?
If you want to only hide the ContextualBalloon's view you can try to use this.balloon.view.hide()
Here's the scenario:
I'm working with Xamarin forms and using FreshMVVM.
My main screen is a FreshTabbedFONavigationContainer, one of the tabs navigate deeper into other pages while the others don't. If I'm in one of those deeper pages and do:
CoreMethods.PushNewNavigationServiceModal(...)
the next navigation page is added to the stack and the back button appears and works fine.
But if I call the same method from a root page in my main tabs page, the back button doesn't appear. I'm calling the same method, the same way, with the same argument types. I've even tried the same arguments.
Why would it work from a deeper FreshBasePageModel and not from the first FreshBasePageModel in a FreshTabbedFONavigationContainer? I've tried FreshTabbedNavigationContainer too and it made no difference.
Also, is there a way to force the back button to show and manage its behavior?
I have a C#.NET MVC3 web app. I have a View that has a List of Models. This list can be long, requiring the user to scroll down on the View. When selecting one of the models in the View to Edit, the user is taken to the Edit View. After submitting the Edit View, the user is redirected back to the List View. However, the List View is now displaying back at the top of the list. How can I redirect the user back to the same position in the List View where they clicked the Edit button?
You would probably be better suited using a modal popup dialog to edit the data, rather than navigating to another page.
While it's possible to do what you want, it's a pain. You would have to get the scroll location via javascript, save it to a hidden field, post that to your edit page, along with record number and anything else, then re-post it back to your original page when you return, then read the post value and scroll to it via javascript.
All that is avoided if you just use a modal edit dialog, then when the dialog goes away the page is still in the same place.
