IsEditable ComboBox LostFocus called initially instead of GotFocus event while focus ComboBox WPF RRS feed

  • Question

  • I have checked WPF ComboBox with IsEditable as true. 

    While focus ComboBox, LostFocus event called first time, then GotFocus have called. 

    How to resolve this?

    Code :


                <ComboBox Height="40" Width="200"
                      LostFocus="ComboBox_LostFocus" IsEditable="True"/>
                <TextBox Text="TextBox" Height="30" 
                         Width="200" />
            <StackPanel Grid.Column="1">
                <Button Content="Clear" Width="100" Height="50" Margin="10"
                <ListView x:Name="listview"  Margin="10" Height="300">


      private void ComboBox_GotFocus(object sender, RoutedEventArgs e)
            private void ComboBox_LostFocus(object sender, RoutedEventArgs e)
            private void Button_Click(object sender, RoutedEventArgs e)
