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.

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

When using OneWay mode binding for RadSideDrawer.IsOpen property, the drawer doesn't open when changing the view model property value.

XAML Implementation

<primitives:RadSideDrawer  IsOpen="{Binding IsOpen}">


ViewModel Property Implementation:

private bool isOpen = true;
public bool IsOpen
{
     get { return isOpen; }
     set { SetProperty(ref isOpen, value); }
}



WORKAROUND:

Changing the binding to TwoWay mode will make it work, for example:  IsOpen="{Binding IsOpen, Mode=TwoWay}"

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.

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.

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.

For example, if you scroll down and then scroll up to the previous pages, they do not show any content.

When the custom ItemTemplate sets bigger value of its Height e.g. more than 44 pixels, the content of the UITreeViewCell is not sized correctly. Only the cell gets the correct value.

Hi!

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.

Hi,

I rolled my app with the ListView out to production and are getting 8+ crashes a day from 140 users with the above issue. I have included a stack trace. I cannot find the steps to reproduce the issue in development. I have rolled back to using the native ListView as this does not crash the app.

Attached is an example project to see what I am doing in general terms, but I have not been able to reproduce this crash in it.

My guess is that a DataTemplate is not being cleaned up properly and when the data behind is changed it attempts to access the control that represented the data in the DataTemplate.

Regards
Anthony
