    Then I click on a MaskedTextInput, it's all selected and in insert mode, so if I have '8888' in the value and press 1, everything is replaced by 1.

    When I set the focus on the code behind, I press '1' and get '1888' then when I press 1 again I get '11888' .  It's very strange behavior.

    I have some sample code below.  When you press the button I programmatically set the focus on the RadMaskedTextInput.  Compare this to when you selected it with a mouse, or tab to it:

    <Window x:Class="FocusOnTextBox6.MainWindow"
            Title="MainWindow" Height="350" Width="525">
                <Style x:Key="UpperCodes6Mask" TargetType="telerik:RadMaskedTextInput">
                    <Setter Property="FontFamily" Value="Segoe UI" />
                    <Setter Property="Margin" Value="0 0 0 0" />
                    <Setter Property="Width" Value="60" />
                    <Setter Property="Height" Value="20" />
                    <Setter Property="Padding" Value="0" />
                    <Setter Property="Placeholder" Value=" " />
                    <Setter Property="IsClearButtonVisible" Value="False" />
                    <Setter Property="TextMode" Value="PlainText" />
                    <Setter Property="SectionsNavigationMode" Value="None" />
                    <Setter Property="IsLastPositionEditable" Value="False" />
                    <Setter Property="InputBehavior" Value="Insert" />
                    <Setter Property="SelectionOnFocus" Value="SelectAll" />
                    <Setter Property="Mask" Value=">a6" />
            <StackPanel Orientation="Horizontal">
                <telerik:RadMaskedTextInput Margin="3 0 0 0" Height="20" Padding="0"  Style="{StaticResource UpperCodes6Mask}"
                        Name="tbClid" />
                <TextBox Name="tbTest" Margin="10 0 0 0" Height="25"  Width="50"/>
                <Button Name="btnTest" Margin="20 0 0 0" Content="Test Focus" Height="25" Width="100" Click="btnTest_Click" />
                <Button Name="btnTestRegular" Margin="20 0 0 0" Content="Test Focus TextBox" Height="25" Width="100" Click="btnTestRegular_Click" />

    namespace FocusOnTextBox6
        /// <summary>
        /// Interaction logic for MainWindow.xaml
        /// </summary>
        public partial class MainWindow : Window
            public MainWindow()
            private void btnTest_Click(object sender, RoutedEventArgs e)
                tbClid.Value = "8888";
            private void btnTestRegular_Click(object sender, RoutedEventArgs e)
                tbTest.Text = "9999";
