I have `Request.xaml` with button and with many comboxes, so I want reload it and put combox values to put it to default after button click. Of course I do some more staff.

My `Request.xaml` code has such parts of the code:

```
<TextBox x:Name="TxtBlock_numRequest" TextWrapping="Wrap" Height="23"/>

                <ComboBox  x:Name="CmbBox_lvlPriority" Width="160"> 
                   <ComboBoxItem Content="1" Name="High" />
                   <ComboBoxItem Content="2" Name="Medium" />
                   <ComboBoxItem Content="3"  Name="Low" />
                   </ComboBox>    

```

In addition, xaml code such *event* `<Button Content="Next request" Width="160" VerticalAlignment="Bottom" Background="#FF339933" Click="Button_Click" />`

And `Request.xaml.cs` file have just `private void Button_Click(object sender, RoutedEventArgs e)` function.

I display `Request.xaml` this way: first of all, `MainWindow.xaml` displays `MainPage.xaml`, 
 `<mui:Link DisplayName="Generation" Source="/Pages/MainPage.xaml" />`,
 and finally `MainPage.xaml` dispays `Request.xaml``

Is it possible to reset the whole page, because I need to give user opportunity to add new request's parameters to existing parameters, which eventually will be located in a `.xml` file?

May be it is possible to realize via **OnNavigatedTo Method** or by **UIElement.InvalidateVisual Method** (<http://msdn.microsoft.com/en-us/library/system.windows.uielement.invalidatevisual.aspx>)
