When RadPdfViewer is used in a master-detail page, I should maintain the previous page index when I traverse between pages.

In Xamarin Forms there is a serious need for a Rich Text Editor control that would allow you to do this such as highlight text, apply fonts, styles etc. I think a tool like this is in great demand among Xamarin developers. Currently there are some Open source controls that have implemented these features however they have not been maintained and cannot be relied on for enterprise solutions

Please add a search option to PDF Viewer.

It will be great If you can also add a thumbnail preview option to view all pages in the PDF and a page slider to help navigate user to any page in seconds.

April 2020 Deadline

Apple will no longer accept applications published with anything less than Xamarin.Forms 4.5 after April 2020.

This is due to the UIWebView flag that is in Xamarin.Forms 4.4 and earlier

ITMS-90809: Deprecated API Usage- Apple will stop accepting submissions of apps that use UIWebView APIs starting from April 2020 . 

Solution

Please visit this documentation for full explanation. Just to share the highlights, Telerik UI for Xamarin will need to:

• Xamarin.Forms 4.5 or higher – Pre-release versions of Xamarin.Forms 4.5 can be used.
• Xamarin.iOS 13.10.0.17 or higher – Check your Xamarin.iOS version in Visual Studio. This version of Xamarin.iOS is included with Visual Studio for Mac 8.4.1 and Visual Studio 16.4.3.
• Remove references to UIWebView – Your code should not have any references to UIWebView or any classes that make use of UIWebView.

Add MVVM friendly commands for all list view interaction events: ItemTapped, ItemSwipeStarting, ItemSwiping, ItemSwipeCompleted, RefreshRequested

I want to easily create a nice looking profile page, news page, and etc by using a template just like what I can do using bootstrap script and css in html

On UWP and Android the item can be swiped beyond the SwipeOffset property. Add option to restrict the swiped distance to the SwipeOffset value.

Provide API which enables the group headers to remain in the view when scrolling until the next ones push them away.

Add controls to selecting dates/times that also support null or blank values.  Currently the DatePicker control that is provided as part of Xamarin Forms doesn't allow for a null or blank date.
Provide the ability to select date and time in single UI.

Add public-facing methods to re-call DataSourceProvider GetSourceFor methods. This would allow for refreshing the datasource.

Alternatively, add support for ObservableCollection to be used for DataSources so that the pickers reflect any changes to the underlying data source.

Sets the number of pixels from the screen edges that will define the touchable area which allows to open the DrawerContent

The property is available in native controls:

Android: TouchTargetThreshold
iOS: EdgeSwipeTreshold
UWP: TouchTargetThreshold

Currently, all groups are expanded by default. We should expose methods to collapse/expand certain groups. Furthermore, CollapseAll, ExpandAll groups should be considered as well.
