Solution 1

Try using MediaElement control you will can play a video in WFP.
The following example shows simple XAML code:

XML

<mediaelement name="VideoControl" width="200" height="400" source="my_file.wmv">    
</mediaelement>

To know how to use the MediaElement please see here: MediaElement Class[^]

Solution 2

The wpf panel control doesn't have handle but you can use windows forms panels in wpf to.

Edit:
First you should add reference to
WindowsFormsIntegration (for the WindowsFormsHost)
and System.Windows.Forms (for the panel).

Then you should add an xmlns to your xaml file.

XML

xmlns:WinForms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

than your xaml file would look like something like:

XML

<Window x:Class="TestWpf.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:WinForms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <WindowsFormsHost>
            <WinForms:Panel x:Name="videoPanel"></WinForms:Panel>
        </WindowsFormsHost>
    </Grid>
</Window>

then you can use the panel in your code behind like in window forms
videoPanel.Handle

Old:
You could do it in code like

C#

WindowsFormsHost host = new WindowsFormsHost();

host.Child = wfPanel;

this.gridPreview.Children.Add(host);

from url: panle handle in wpf[^]

Or in xaml code

XML

<WindowsFormsHost Height="100" HorizontalAlignment="Left" Margin="10,108,0,0" Name="windowsFormsHost1" VerticalAlignment="Top" Width="200">
    <WinForms:Panel BackColor="Red" Dock="Fill">
    </WinForms:Panel>
</WindowsFormsHost>
