Question

<Grid x:Name="LayoutRoot">
    <TextBox x:Name="TxtFocusOut" Height="74" Margin="186,149,225,0" TextWrapping="Wrap" VerticalAlignment="Top" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="26.667" TextChanged="TextBox_TextChanged"/>
</Grid>

private void TextBox_TextChanged(object sender, System.Windows.Controls.TextChangedEventArgs e)
    {
        if(TxtFocusOut.Text.Length>=4)
        {
            MessageBox.Show("Four you typed four values");
        }
    }

单击Ok Button On消息框后，光标应该从texbox中聚焦。但现在它在文本框中闪烁。我该怎么做才能从测试框中聚焦？
