Windows phone 7 keyboard size

问题

I want to resize the page when the keyboard appears on the screen.

I was looking for any clue all day but I can't find anything.

In my case. I want to have full page TextBox and some buttons under it.

<Grid x:Name="RootLayout" >

    <Grid >
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="70"/>
        </Grid.RowDefinitions>

        <ScrollViewer Margin="0" >
            <TextBox TextWrapping="Wrap" Text="TextBox" AcceptsReturn="True" VerticalScrollBarVisibility="Auto" Height="698" Width="480"/>
        </ScrollViewer>

        <Canvas x:Name="RootMenu" Margin="0,1,0,0" Grid.Row="1" />
    </Grid>

</Grid>

I use to thing that the first row will change its size automatically, but it doesn't happening.

Please help me.

I'm going to dislike this OS! Proposed solution is not good at all. When the keyboard is visible then I can not scroll it down.

Lets say I want just simple TextBox to let users write something. But it is impossible !!

<phone:PhoneApplicationPage.ApplicationBar>
    <shell:ApplicationBar IsVisible="True">
        <shell:ApplicationBarIconButton IconUri="/icons/appbar.check.rest.png" Text="aplay"/>
    </shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>

<Grid x:Name="RootLayout" >
    <ScrollViewer>
        <TextBox  Text="TextBox" AcceptsReturn="True" VerticalScrollBarVisibility="Auto" />
    </ScrollViewer>
</Grid>

There isn't a way to know for sure if the SIP is displayed. Jaime Rodriguez has a post showing how to make a fairly reliable guess of this.

If you want to have "buttons" that are always displayed then the best, and only reliable, way to do this is to use the ApplicationBar.
