Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled.

I've attached a handler to the ViewChanged event of the Calendar component.

The event fires on Android but not on UWP. I've tried changing the view type using the calendar controls and also programatically but the event is not being fired.

With Automatic LoadOnDemand, once all items are loaded and IsLoadOnDemandEnabled is set to false, when I scroll till the end the loading indicator keeps flickering on knowing that no more items are called.

We have implemented chat functionality using Telerik RadChat component. The problem is that the scroll functionality doesn't scroll fully to the bottom on IOS. It randomly stops somewhere in between. The same code runs perfectly on Android. Below I have attached an example code of our solution.


<telerikConversationalUI:RadChat 
          BackgroundColor="White" 
          Grid.Row="1" 
          x:Name="chat" 
          Author="{Binding Me}"
          ItemsSource="{Binding Items}"
          AutoScrollMode="Always"
          ItemConverter="{StaticResource SimpleChatItemConverter}" 
          SendMessageCommand="{Binding NewMessageCommand}"
          ItemTemplateSelector="{StaticResource CustomChatItemTemplateSelector}"
          SendMessageButtonImage="ic_send_green">
</telerikConversationalUI:RadChat>

When you have custom ItemTemplates defined with different height, scrolling up through the items causes flickering, also you cannot scroll down to display all the items.

if the swipe content of the cells are buttons, dragging the buttons up and down will keep the swiped cells in the same position of the screen, creating unexpected animations and showing the entire swipe content of the cell.

When swiping a cell, the swipe content of the cell will be shown if the swipe threshold is reached.  On iOS, the swipe content of another cell can be shown immediately by swiping another cell (which is an expected behaviour).  However on Android, when the user swipes another cell, the swipe content of the other cell isn't shown (while the swipe content of the first cell becomes hidden).  The user has to swipe the other cell again to show the swipe content.

If there is an input control (Editor, Entry) inside the ItemTemplate of the TreeViewDescriptor and its Text is bound to any property of the data item, changing the ItemsSource of the TreeView raises an exception of type AccessViolationException.

Currently IsCheckedChanged command is raised when the BindingContext of the CheckBox is updated and this is a change in the behavior compared to previous releases.

Activating the ItemHold event of an item in a list view requires holding down an item for a while.  On a physical/virtual Android device and a virtual iOS device, this can be done by holding down the mouse/finger lightly on an item for a short period of time.  However, on a physical iOS device (I am using a physical iPhone 6s to test this), holding down the item lightly with my finger won't activate the ItemHold event, and I have to hold the item really hard on the screen in order to activate it (similar to using 3D Touch / Force Touch, and I cannot reliably activate the ItemHold event possibly because my force is sometimes not hard enough).  I noticed this behaviour on the physical iOS device since the ItemHold event got implemented in early 2018.

I created a simple application to demonstrate the issue.  The app displays an alert when the user taps/holds an item in the list view.  On a physical iOS device, holding down an item in the list view requires the user to press the item very hard on the screen.

Thanks,
Kori

If you set selected date range when the Calendar is loaded, the selection is not visualized.

When you update the data in the chart so that the vertical axis values are changed - the annotation does not properly update and stays at the same location.

If there are input controls inside the templates, updating a property of any data item though an input control ( such as Entry, NumericInput, etc),  caused the control to lose focus.

By specification, names are an atomic symbol uniquely defined by a sequence of characters. However, when importing a document with names defined as an empty sequence a handled InvalidCastException is thrown which leads to missing page content.

If you set SelectedDate when the Calendar control is created, does not take any effect in the UI on iOS. 

As a workaround, set SelectedDate at a later stage.

I have a Xamarin.Forms app, but I only am using it for UWP at the moment. The plan is to have Android and iOS later, but I am having issues with the RadNumericInput (Xamarin.Forms) and how the decimal key is handled.

Here is my XAML


<tkInput:RadNumericInput Grid.Row="4" Grid.Column="1" Value="{Binding Price, Mode=TwoWay}" StringFormat="{}{0:C2}" />


Right now, "Price" will default to 0. The UI will initially show $0.00 because of the StringFormat. That is working fine. When I put focus into the control, I only see 0, that is also fine. The issue is when I try to type a decimal. The value disappears and I see an issue in my Output that says -- Binding: can not be converted to type 'System.Int32'

 

Example steps:

  • With the value set to 0.00
  • Focus the control -- you will now see just 0
  • Press the decimal key (aka the period key)
  • Notice the error in the Output window in VS and also the control shows nothing at all
  • If you press the decimal key again, you will see two decimals in the control

**** Also, the Version of the Telerik controls I am using is -- 2019.2.603.360. The drop down below doesn't let me choose that version.

When you initiate a swipe gesture and the SwipeContentTemplate is shown,  changing the device orientation from portrait to landscape, does not update the ListView layout and the swiped item width is incorrect.

If we have a ListView with a CheckBox inside the ItemTemplate and the whole ListView is placed in a Popup control, following the next steps:

1. Open the popup

2. Check and uncheck the CheckBox control in any of the items.

3. Click into the popup and then outside to close it.

NullReferenceException is raised on iOS.
