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 Scroll down and you will see that an item in the list has been replaced by Item 1 which is now in the list twice.

Regards

Anthony

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.

   Stack Trace from the Native Crash Reporting from the Application Output Window.

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.

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.

When using TwoWay binding for AutoComplete on iOS, the Text is cleared using the Clear button, the Text property is not updated.

Also, as a confirmation, the Xamarin.Forms PropertyChanged event is also not fired for the RadAutoComplete.Text Property 

Test 1 : Use the following repro for the Binding test:

<telerikInput:RadAutoComplete Text="{Binding SelectedInsurer, Mode=TwoWay}" />

public string SelectedInsurer
{
    get => selectedInsurer;
    set
    {
        SetProperty(ref selectedInsurer, value);
        // This is not hit on iOS when the Text is cleared using the "X" button
    }
}


Test 2 : Use this code for the PropertyChanged test:

AutoComplete.PropertyChanged += AutoComplete_PropertyChanged;

// Not executed on iOS when the Clear button is used.
private void AutoComplete_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "Text")
    {
        Debugger.Break();
    }
}

When the value of Text is set in XAML, Text value is ignored on Android. Use this example:

<telerikInput:RadAutoComplete x:Name="autoComplete" Text="Initial Text" Watermark="watermark" />

Observe that only the watermark appears (note: this issue happens with or without watermark).


Workaround:

Set the value of Text after view has loaded, for example in OnAppearing:

protected override void OnAppearing()
{
    base.OnAppearing();

    autoComplete.Text  = "OnAppearing";
}
