We are using your component SlideView on Main Page of our app. Unfortunately when we upgraded Xamarin Forms to 4.0 version we are facing exception - System.NotSupportedException: Unable to activate instance of type Telerik.XamarinForms.PrimitivesRenderer.Android.SlideViewRenderer from native handle 0x75 (key_handle 0x60775bd). ---> System.MissingMethodException: No constructor found for Telerik.XamarinForms.PrimitivesRenderer.Android.SlideViewRenderer::.ctor(System.IntPtr, Android.Runtime.JniHandleOwnership) ---> Java.Interop.JavaLocationException: Exception of type 'Java.Interop.JavaLocationException' was thrown.
Steps to reproduce:
1) Open app with SlideView and BottomNavigationBar
2) Navigate to any another tab
3) Back to main page tab
4) App is crashing with this exception.
It could be important information to reproduce this but it doesn't happend on every tab. We have five tabs in app (Main Page and 4 additional) and it crashes only on navigation between main page and last tab.
I guess that could happend when SlideView disposes or reloads.
The second item is visible, but the index does not seems updated, after the second swipe again the second item is visible, but now the index is updated and the next swipe leads to the third item.
When SlideView contains ContentViews, it does not always update SelectedIndex (or visible item) after swiping on iOS
Switching the views is executed by setting SelectedIndex property of the SlideView. Available in minor release 2018.3.1109. It will also be available in the R1 2019 release.
Refer to the attached reproducible, The DataTemplateSelector should be returning RedTemplate and BlueTemplate every other item. However, the SlideView is not making calls to the selector and incidentally reuses the wrong template for multiple items in a row, Available in minor release 2018.2.821. It will also be available in the R3 2018 release.
Available in the 2018 R2 SP release.
First item content doesn't update when starting with an empty ObservableCollection even though an indicator is present. Steps to repro: 1- Starting with an empty ObservableCollection<T> ItemsSource 2 - Add two items (notice 1st item's content stays empty) 3 - Slide to the 2nd item (notice content is visible) 4 - Slide back to 1st item (notice content is now visible) Attached a runnable repro. Available in minor release 2018.1.405. It will also be available in the R2 2018 release.
When the SlideView is bound to a collection containing 1000 items it takes long time (15 seconds) to visualize the control. Available in the R2 2018 release.
Available in minor release 2018.1.0315. It will also be available in the R2 2018 release.
Available in minor release 2017.3.1214. It will also be available in the R1 2018 release.
In a scenario where you would like to cancel the sliding to a specific index, you should use the SlidingToIndex event and cancel it. However, this action results in freezing the control. Available in minor release 2017.3.1214. It will also be available in the R1 2018 release.
The only way to customize the SlideView indicators is to predefine the SlideView ControlTemplate. Available in the R1 2018 release.
