ShowDialog and Show methods throw exception

[Alexey]

Hi,

I've get following error.

Show and Show Dialog methods are called from usercontrol that was dynamically created

    public partial class Dialog : UserControl
    {
        public Dialog()
        {
            InitializeComponent();
            window.ShowDialog();
        }
    }




Everything works nice when we use it pure new empty project, but inside our application which has deep control hierarchy it drop that exception.

Thanks,
Alexey Zakharov.

<UserControl x:Class="RadWindowExperiment.Dialog"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:nav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
    >
    <Grid>
        <nav:RadWindow x:Name="window" ModalBackground="#AA000000" WindowStartupLocation="CenterScreen"   >
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="100"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>
                <Rectangle Grid.Row="0" Fill="LemonChiffon" Width="100" Height="100"/>
            </Grid>
        </nav:RadWindow>
    </Grid>
</UserControl>

With this hack I've tried to simulate Silverlight ChildWindow behavior when Window is just another usercontrol. But in this case usercontrol are not actually loaded. That is why data binding inside radwindow breaks everything and we get that exception.

What is the best way to use RadWindow as standart ChildWindow?

[Alexey]

I solved the problem!

I've just placed Window as root element.

<nav:RadWindow x:Class="RadWindowExperiment.Dialog"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:nav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
    x:Name="window" ModalBackground="#AA000000" WindowStartupLocation="CenterScreen"
    >
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="100"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <Rectangle Grid.Row="0" Fill="LemonChiffon" Width="100" Height="100"/>
    </Grid>
</nav:RadWindow>

Now it starts working OK.
