I use Catel. I need to prevent focusing the first menu item of my application on startup.
This is my window:
<catel:Window x:Class="SpringExpert.Views.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:catel="http://schemas.catelproject.com"
ShowInTaskbar="True"
ResizeMode="CanResize"
Style="{StaticResource WindowStyle}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Menu Style="{StaticResource MenuStyle}">
...
</Menu>
</Grid>
</catel:Window>
On startup of my application the first menu item is focused.
