the following exceptions occur when upgrading to Xamarin.Forms v 4.0:
System.NotSupportedException: Unable to activate instance of type Telerik.XamarinForms.DataControlsRenderer.Android.ListView.TemplateCellContainer
System.NullReferenceException: Object reference not set to an instance of an object
I have an custom column extending "DataGridTextColumn". This column overrides "CreateGroupDescriptor" methods and returns an instance of "DelegateGroupDescriptor". Once we group items in this column it can never be cleared/un-grouped.
Any help would be heighly appreciated. Thanks in advance.
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.
Available in the 2018 R2 SP release.
The chart BindingContext does not propagate correctly to some of its children, e.g. axes and grid. Available in the R3 2018 SP release.
Images loaded from memory stream behave strange - on iOS they don’t load immediately, only after list is scrolled and after that they start resizing and reordering randomly when scrolling; on UWP they load on initialization but have same problem with reordering.
When there is custom template applied that hosts multiple rows of UI components with total height greater than 44, the template is not measured correctly, leading to wrong visualization.
