I recently migrated my code from Xamarin.forms to MAUI.
RadListView.GetDataView now always returns null in MAUI , its working fine in Xamarin.forms. 

I am trying to  close all the groups while loading, but facing a null exception with DATAVIEW

protected override void OnAppearing()
{
        base.OnAppearing();
        try
        {
 //collapse all
 var dataView = MyRadListView.GetDataView();
 dataView.CollapseAll();}}    

Regardless of the RadEntry's BackgroundColor property, I've noticed the visible-background-color to differ when the RadEntry receives active focus.

The observed behavior is this:

• RadEntry's visible-background-color generally equals RadEntry's BackgroundColor property
• RadEntry's visible-background-color changes to gray when hovered regardless of day-night mode
• RadEntry's visible-background-color changes to white when focused
• RadEntry's visible-background-color restores to RadEntry's BackgroundColor when unfocused

Typically, in day mode settings (Windows default), the RadEntry's BackgroundColor == white so you don't see the problem. However, in night mode settings (Android default), we want the RadEntry's BackgroundColor == black so the problem is more prevalent since you're typing white text on a white background.

When using Visual States, and, if you try to re-enforce the same BackgroundColor property in all of the visual states, sometimes focus, hover, unfocus, hover, focus sequence will allow you to edit in the RadEntry in your desired RadEntry's BackgroundColor property instead of white, but, most of the time is white.

This problem can be reproduced on Windows and Android if you set your application to night mode Application.Current.UserAppTheme = AppTheme.Dark and set RadEntry's BackgroundColor=Black and TextColor=White in XAML. Put 2 or 3 RadEntry's on the page so you can navigate between them to see the problem.

Hello,

there is probably a Bug in the ListPicker Commands. (https://docs.telerik.com/devtools/maui/controls/listpicker/commands)

Like in the example:

  private void OnAccept(object obj)
    {
        // implement your custom logic here
    }

the object is null. 

In certain situations, the RadTabView cuts off part of the header text for some of the headers.  A specific scenario where this is happening is when the following tabs are present: 

• General
• Feed
• Users (0)
• Relationships (0)
• Tickets (0)
• Attachments (0)

The problem is worse when the BorderThickness of the TabViewHeaderItem is set to 1

  <Grid>
    <telerik:RadTabView>
      
      <telerik:RadTabView.HeaderItemStyle>
        <Style TargetType="telerik:TabViewHeaderItem">
          <Setter Property="BorderColor"
                  Value="Black" />
          <Setter Property="BorderThickness"
                  Value="1" />
        </Style>
      </telerik:RadTabView.HeaderItemStyle>
      
      <telerik:TabViewItem HeaderText="General" />
      <telerik:TabViewItem HeaderText="Feed" />
      <telerik:TabViewItem HeaderText="Users (0)" />
      <telerik:TabViewItem HeaderText="Relationships (0)" />
      <telerik:TabViewItem HeaderText="Tickets (0)" />
      <telerik:TabViewItem HeaderText="Attachments (0)" />
      
    </telerik:RadTabView>
  </Grid>

Hello,

I am trying to run the Controls Sample to get familiar with the controls. However, I am unable to run the app on my attached iPhone. 

The app begins to load and then crashes.

    <VerticalStackLayout>
        <Label 
            Text="Welcome to .NET MAUI!"
            VerticalOptions="Center" 
            HorizontalOptions="Center" />
        <Label Text="Status:" />
        <telerik:RadComboBox/>

    </VerticalStackLayout>

This works for Android. IOS gives error "Cannot resolve type "http://schemas.telerik.com/2022/xaml/maui:telerik:RadComboBox" 

But  telerik:RadCheckBox does not have the same problem.

   <VerticalStackLayout>
        <Label 
            Text="Welcome to .NET MAUI!"
            VerticalOptions="Center" 
            HorizontalOptions="Center" />
        <Label Text="Status:" />
        <telerik:RadCheckBox IsChecked="True"/>

    </VerticalStackLayout>     

Will work for IOS and Android.

How do I fix this?

I am using VS Community 2022 Preview 

Version 17.3.0 Preview 6.0

and Telerik.UI.for.Maui.Trial 2.2.0
