Answer 1

I wanted to do the same thing, but nothing seemed to work for me. I really needed an answer that worked purely in XAML as I'm working with MVVM.

I finally found this example: http://spin.atomicobject.com/2013/03/06/xaml-wpf-textbox-focus/

and modified it to this:

In the 'Resources' section:

    <Style x:Key="FocusTextBox" TargetType="Grid">
        <Style.Triggers>
            <DataTrigger Binding="{Binding ElementName=textBoxName, Path=IsVisible}" Value="True">
                <Setter Property="FocusManager.FocusedElement" Value="{Binding ElementName=textBoxName}"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>

In my grid definition:

<Grid Style="{StaticResource FocusTextBox}" />

I like these do-my-homework-for-me questions; "the requirement states"...priceless. For those who find this via Google, the trick to progmatically moving the cursor in a WPF TextBox is to use the SelectioNStart property.

private void Button_Click(object sender, RoutedEventArgs e)
{
    textBox.Focus();
    textBox.SelectionStart = textName.Text.Length;
}
