When the control is inside listview and the drop-down is displayed, if you tap outside of the combo, the drop-down does not close.

if you have the following setup, more than one ComboBox controls:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <telerikInput:RadComboBox Grid.Row="0"
                                ItemsSource="{Binding Items}" 
                            DisplayMemberPath="Name"                        
                            SearchTextPath="Name"
                            SearchMode="Contains"
                            Placeholder="select a response..."
                            FontSize="12"
                                x:Name="popup1"
                            SelectionMode="Single"
                            HorizontalOptions="FillAndExpand"
                            HighlightTextColor="DarkOrange"
                            IsDropDownClosedOnSelection="True"
                            IsEditable="True">
           
    </telerikInput:RadComboBox>

    <telerikInput:RadComboBox ItemsSource="{Binding Items}" 
                                DisplayMemberPath="Population" 
                                Grid.Row="1" x:Name="popup2"                      
                            SearchTextPath="Population"
                            SearchMode="Contains"
                            Placeholder="select an employee..."
                            FontSize="12"
                            SelectionMode="Single"
                            HorizontalOptions="FillAndExpand"
                            HighlightTextColor="DarkOrange"
                            IsDropDownClosedOnSelection="True"
                            IsEditable="True">
    </telerikInput:RadComboBox>
</Grid> 

 

and when the user clicks on the first/second control but did not select an item and clicks on another combo, the entry steals focus and cannot close the dwop/down or navigate away.

ComboBox text is not visible when the control is inside Grid.Row="40" and testing on device with 800x1200 mdpi: 

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="40"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="20"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <telerikInput:RadComboBox BackgroundColor="Yellow" Padding="0" 
                                Margin="0"
                                Grid.Column="2" x:Name="combo" 
                                Grid.Row="0"/>
        
        
</Grid>



Workaround: 

set higher grid row height: 60 or above, or using Auto row height.

For example when setting the following code in App.xaml resources

<Style TargetType="telerikInput:RadComboBox">
                <Setter Property="DropDownBorderColor" Value="Red"/>
                <Setter Property="VerticalOptions" Value="Center"/>
                <Setter Property="SearchMode" Value="Contains"/>
                <Setter Property="Placeholder" Value="rwfrfre"/>
                <Setter Property="PlaceholderColor" Value="Yellow"/>
                <Setter Property="DisplayMemberPath" Value="Population"/>
                <Setter Property="SearchTextPath" Value="Name"/>
            </Style>

 

null ref exception is thrown for DisplayMemberPath and SearchTextPath. 

When setting the style inside the page where the control is defined, it works as expected.

When RadComboBox is placed inside CellContentTemplate of a TemplateColumn of RadDataGrid and ComboBox's SelectedItem property is bound to a property of the data item,  making a selection in any of the ComboBoxes leads to losing the SelectedItem value. The same can be observed when the window (on UWP) is resized or when the device (Android, iOS) is rotated.
