Custom MessageDialougeBox in Windows Store Apps

Question

I am Working On a Windows Store App in which i have to implement a MessageDialougeBox that has more controls then just having some message strings and Buttons.I have checked the MessageDialougeBox class but it is not showing any content template property first i though it is not possible but when i saw the Skype Application for windows 8 they had done that.so how i could achieve that.. any help is appreciated. i want something like this

I know there is a popup control. Actually the point is, I have to apply extra effort on this control to make it look like MessageDialougebox..is there any way that i can change or edit the MessageDialougebox content..

Answer 1

Your requirement is to build Popup window not message box. See this sample

Callisto toolkit provides custom message dialog. Which can host any UI elements. The sample is given below.

XAML

<Page
................
xmlns:callisto="using:Callisto.Controls">
    <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
        <callisto:CustomDialog x:Name="LoginDialog" 
                                Title="Bacon Terms and Conditions" 
                                Background="Teal" BackButtonVisibility="Visible">
            <StackPanel>
                <TextBlock Margin="0,0,0,8" FontSize="14.6667" FontWeight="SemiLight" TextWrapping="Wrap">
                    Bacon sausage frankfurter tenderloin turkey salami andouille bresaola. Venison salami prosciutto, pork belly turducken tri-tip spare ribs chicken strip steak fatback shankle tongue boudin andouille.

                </TextBlock>
                <CheckBox Margin="0,0,0,8" Foreground="White" Content="I agree to the Terms and Conditions of Bacon" />
                <TextBlock Margin="0,0,0,8" FontSize="14.6667" FontWeight="SemiLight" Text="Enter your name for acceptance" />
                <callisto:WatermarkTextBox HorizontalAlignment="Left" Watermark="Type your name" Width="400" Height="35" />
                <StackPanel Margin="0,20,0,0" HorizontalAlignment="Right" Orientation="Horizontal">
                    <Button Content="OK" Width="90" Margin="0,0,20,0" />
                    <Button Content="Cancel" Width="90" />
                </StackPanel>
            </StackPanel>
        </callisto:CustomDialog>
    </Grid>
</Page>

CS

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    LoginDialog.IsOpen = true;
}

The output
