ScrollViewer with ItemsControl not working

<ScrollViewer VerticalScrollBarVisibility="Visible"  Height="100">
        <ItemsControl Name="icReviews" BorderBrush="Black" BorderThickness="1" Height="300">
            <ItemsControl.Background>
                <LinearGradientBrush StartPoint="0,0" EndPoint="1,1" >
                    <GradientStop Offset="1" Color="#FFFF9900" />
                    <GradientStop Offset="0" Color="#FFDD4400" />
                </LinearGradientBrush>
            </ItemsControl.Background>

            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <UniformGrid Columns="3" Width="1712" Height="300"></UniformGrid>
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>


            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition ></RowDefinition>
                                <RowDefinition></RowDefinition>
                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto"></ColumnDefinition>

                            </Grid.ColumnDefinitions>
                            <StackPanel Grid.Row="0" Grid.Column="1" TextElement.FontFamily="FangSong" TextElement.FontSize="15"  TextElement.FontWeight="Bold" TextElement.Foreground="Blue">
                                <TextBlock Text="{Binding Path=Subject}" Foreground="White" TextElement.FontSize="15" TextElement.FontFamily="FangSong" TextWrapping="Wrap" Margin="5,5"></TextBlock>
                                <TextBlock Text="{Binding Path=Review}" Foreground="White" TextElement.FontSize="15" TextElement.FontFamily="FangSong" TextWrapping="Wrap" Margin="5,5"></TextBlock>
                                <WrapPanel>
                                    <StackPanel Orientation="Horizontal">
                                        <TextBlock Text="Posted by : " Foreground="White" Margin="5,5" TextElement.FontSize="15"></TextBlock>
                                        <TextBlock Text="{Binding Path=Username}" Foreground="White" TextElement.FontSize="15" TextElement.FontFamily="FangSong" Margin="5,5"></TextBlock>
                                    </StackPanel>
                                </WrapPanel>
                            </StackPanel>
                        </Grid>
                    </StackPanel>
                </DataTemplate>
            </ItemsControl.ItemTemplate>

        </ItemsControl>
    </ScrollViewer>

I have now edited my code with the height attribute of scrollviewer. I still cant see any scrollbars

Are you giving your ScrollViewer a height, or constraining it within a panel that limits the height of its children?

If the height is not limited in some way, there's no reason for the ScrollViewer to show the scrollbars as it can grow to whatever height it needs to display its children.

You can test it by setting the VerticalScrollBarVisibility and HorizontalScrollBarVisibility to Visible to see where your ScrollViewer actually is, and if this is the case then you can fix the issue by either seting the ScrollViewer.Height to a value, or wrapping it in a container that does not allow its children to grow to whatever size they want.

You have to define a ControlTemplate for ItemsPresenter that contains a ScrollViewer. I don't believe it includes one by default...
