Hi,

Snip from the solution: "Actually after calling the "SetActivePattern" the control return to the Listview changed event and it retun to ListView. So again the Focus moved to ListView."

I don't see this. Here's a simple version:

<Window x:Class="WpfApplication1.Junk"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Junk" Height="300" Width="300">
    <StackPanel>
        <Button Height="23" HorizontalAlignment="Left" Margin="50,30,0,0" Name="button1" VerticalAlignment="Top" Width="75">Button</Button>
        <TextBox Height="23" Margin="40,66,88,0" Name="txtPatternName" Text="{Binding Path=PatternName, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" VerticalAlignment="Top" />
        <StackPanel>
            <ListBox Height="65" Margin="59,0,120,45" Name="listBox1" VerticalAlignment="Bottom" SelectionChanged="listBox1_SelectionChanged" >
                <ListBoxItem>One</ListBoxItem>
                <ListBoxItem>Two</ListBoxItem>
                <ListBoxItem>Three</ListBoxItem>
            </ListBox>
        </StackPanel>
    </StackPanel>
</Window>

with

       private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            txtPatternName.Focus();
        }

This seems to work fine - why did your code behave differently?
Regards,
Viv

To overcome u start the SetActivePattern function in a Dispatcher.Invoke or BeginInvoke with System Idle priority u get the focus in text pattern. See the sample below

>private delegate void focus(HolePattern NewActivePattern);

>paste the below code inside the lvHolePatterns_SelectionChanged

>this.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.SystemIdle, new focus(SetActivePattern),
>(HolePattern)lvSender.SelectedItem);
