Add a new image cropper control, which allows users to drag/zoom a selected image within a defined frame, so that the resulting image has a defined width and height. This should offer an experience similar to the Facebook app's screen for adding/updating your profile photo. The control should display the non-selected area of the photo with configurable opacity settings, and optionally allow for a resulting circular image.

Hi
I have a radcheckbox whose checked value is set on my view model, it is bound oneway. My View model implements INotify.
When my viewmodel updates the property, the ui does not update. If i set the mode to TwoWay the ui reflects accordingly. I have a converter linked to this same property on another object hence I can't set TwoWay Binding to achieve this(Not included in the sample). The checkbox will just be displaying a state and never be updated by the user
I have tested on iOS and UWP. Have not verified on Android currently, but will require this in future.
Attached is a sample project.
The RadCalendar DayView.EventView get stuck in a shifted position. This only occurs on iOS.
Steps to reproduce:
1. Load calendar.
2. Slowly slide the event view (lower portion) either right or left until the time labels (1am, 2am, etc.) are no longer in their starting positions.
3. Without releasing the scroll, tap the button to change the view to Month view mode.
4. Tap the button to change back to Day view mode.
5. Observe that the entire events view is still shifted and will remain so until the RadCalendar control is destroyed and a new one is created.
Attached are pictures showing the correct view and the incorrect view. Also, a sample project is attached that can be used to replicate this issue.
I have attempted to use a custom renderer to manually reset the events view, but nothing seems to work.
I am Lazy Loading a document in a TabViewItem on the RadTabView Control. Here are the steps.
1. My Page opens and I am on my Main Tab.
2. The user has two Bottom Menu Options, one of them is for a view of a Document.
3. The user selects the Document Tab Option, and the I fire an Async operation that Loads a Byte Array that the PDFViewer is bound to. This loads fine. The document successfully loads in the viewer.
4. The user goes back to the Main Tab
5. The user then selects the Document Tab Option again, the Byte Array is already loaded so I do not Load it again in my ViewModel. So, I am not updating the Source Property on the PDFViewer again once it is loaded. I also tried just reloading the document with the same results.
The application just crashes. My guess is the Rendering or Re-Rendering of the Pdf Document between Tab Selections and there is someting
If the document is never loaded, the app does not crash. However, once I load the document in the PDFViewer that exists on a Tab, the Application will crash if the user moves between tabs.

Example of my Binding. Very simple Byte Array Binding, and out of the box example from the QSF Code. I also tried using a Stream and it does the same thing.

Hi,
On Android, I am using a DataTemplateSelector and a DataTemplate that has a switch on it that the user can press. When the user presses the switch the ListView starts corrupting the data in the list. The item being interacting with starts appearing in other locations on the list.
This issue can be reproduced in the Telerik SDKBrowser project.
Select the following : ListView -> Cell Types -> Template Cell Selector - Xaml
Mark Item1 as special using the button. Scroll down and you will see that an item in the list has been replaced by Item 1 which is now in the list twice.

Anthony
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.
If you have a more complex HeaderTemplate containing input controls, each button placed after a certain position does not fire its Click event. If a button is placed at the top of the template, it functions properly.
Add a Map control to the product suite.
The Android and iOS versions of the control support multiple and range selections. We should consider embedding such features in the Xamarin.Forms control as well.

Hello,
I have a class, a collection of which is displayed in RadListView. If the class has a static property, no single item is displayed in UWP. In Android and iOS it works without this problem.
Regards,
Franz.
