WP8 Out of Memory error while loading Images

问题

I am working on Windows Phone 8 app.

I am working on Coverflow feature, i am trying to load 600 items but it always shows Out of Memory Error

Code:

<DataTemplate x:Key="DataTemplate1">
            <Grid VerticalAlignment="Center" HorizontalAlignment="Center">
                <Grid.RowDefinitions>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <Border Grid.Row="0" Height="400" Width="400" CornerRadius="30,30,30,30">
                    <Border.Background>
                        <ImageBrush ImageSource="Images/sample.png" />
                    </Border.Background>
                </Border>
                <Grid Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Top">
                    <TextBlock HorizontalAlignment="Center" 
                               VerticalAlignment="Center"
                               Margin="5,20,5,5"
                               Foreground="#000000"
                               Text="{Binding Title}"/>
                </Grid>
                <Grid Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Bottom">
                <TextBlock HorizontalAlignment="Center" 
                               VerticalAlignment="Center"
                               Margin="5,5,5,20"
                               Foreground="#000000"
                               Text="{Binding SubTitle}"/>
                </Grid>
            </Grid>
        </DataTemplate>

I have tried checking why its happening so,because each time it loads image with the below code

<Border Grid.Row="0" Height="400" Width="400" CornerRadius="30,30,30,30">
                        <Border.Background>
                            <ImageBrush ImageSource="Images/sample.png" />
                        </Border.Background>
                    </Border>

I tried removing Width and Height and it works but i want the image to bigger.

How can i fix this ?

Here it's been discussed in detail. What you'll need to do is use Memory Profiling and periodically check which the memory Heap to see what's allocated when it shouldn't be.
