Vertical ScrollView of ListView without Height

My UWP application has ListView with dynamic contents. I want to enable ScrollView when it's height reaches to the end of device height it runs(desktop/mobile). I don't want to set height/maximum height of ListView. Because it should display as it is.
I have tried like below. But it is not working. It works only if specify the height of ListView.
<Grid HorizontalAlignment="Stretch" >
<Grid.RowDefinitions >
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<ListView x:Name="ItemListView" Margin="0,0,0,0" ScrollViewer.VerticalScrollBarVisibility="Auto" Grid.Row="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Width="Auto" >
<!--ListView ItemTemplate to fill-->
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="Padding" Value="0" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<Grid >
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width=".8*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Row="0" Grid.Column="0" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.RowSpan="2">
<TextBlock Text="{Binding SerialNum}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Column="1" Grid.Row="0" >
<TextBlock Text="{Binding XX}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Row="0" Grid.Column="2" Orientation="Vertical" >
<TextBlock Text="{Binding YY}" TextAlignment="Center" />
<TextBlock x:Name="tb_list_date" HorizontalAlignment="Center" Text="{Binding ZZ}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Row="0" Grid.Column="3">
<TextBlock Text="{Binding AA}" TextAlignment="Center" />
</StackPanel>
<StackPanel Grid.Row="0" Grid.Column="4" Grid.RowSpan="2" VerticalAlignment="Center" HorizontalAlignment="Center" >
<TextBlock Text="{Binding BB}" TextAlignment="Center"/> </StackPanel>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>

The problem is that the Grid.RowDefinition is set to Auto height. This lets the controls in the row to use any height they need. This causes the ListView to stretch beyond the boundaries of the page and because its height is actually the full height of the list, it does not scroll (but you can't see the overflow).
To fix this, change the Grid.RowDefinition Height to *. This will give the control all available space in the Grid but not more than that:
<Grid HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
...
</Grid>

Focus HambugerMenu Item

Currently I am implementing an app using HamburgerControlMenu from Mahapps.Metro toolkit.
I need to focus a specific HambugerMenu Item by code, after an event.
This is the WPF code:
<Grid.Resources>
<DataTemplate x:Name="aa" x:Key="MenuItemTemplate" DataType="{x:Type viewModels:MenuItem}">
<Grid x:Name="gridMain" Height="48">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="48" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<ContentControl Grid.Column="0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Foreground="White"
Focusable="False"
Content="{Binding Icon}"/>
<TextBlock x:Name="txtBlockMenu"
Grid.Column="1"
VerticalAlignment="Center"
FontSize="16"
Foreground="White"
Text="{Binding Text}" />
</Grid>
</DataTemplate>
</Grid.Resources>
<controls:HamburgerMenu x:Name="HamburgerMenuControl"
Foreground="White"
PaneBackground="#FF444444"
IsPaneOpen="False"
ItemsSource="{Binding Menu}"
OptionsItemsSource="{Binding OptionsMenu}"
ItemClick="HamburgerMenuControl_OnItemClick"
OptionsItemClick="HamburgerMenuControl_OnItemClick"
ItemTemplate="{StaticResource MenuItemTemplate}"
OptionsItemTemplate="{StaticResource MenuItemTemplate}"/>
Little help would be great.

Set the SelectedIndex or SelectedItem property. The following will for example select the second item at index 1:
HamburgerMenuControl.IsPaneOpen = true;
HamburgerMenuControl.SelectedIndex = 1;

you can set it using :
this.*yourHamburgerControlName*.SelectedIndex = *InsertHere the position of your HamburgerMenuItem in the ItemSource*;

Align controls correctly when using ItemsControl in WPF

Can someone tell me how to align and resize controls correctly when using the ItemsControl.
I want to have a description on the left and a TextBox on the right for multiple fields which are defined in an ObservableCollection to end up with something like:
First Name: [FirstNameTextBox]
Last Name: [LastNameTextBox]
Date of Birth: [DobTextBox]
but instead I'm getting this:
First Name: [FirstNameTextBox]
Last Name: [LastNameTextBox]
Date of Birth: [DobTextBox]
I want all the textbox to be aligned based on the largest <TextBlock>. If this was done directly in a <Grid> control, it would be straight forward as all controls are directly in the grid and you would just have the following columns definition defined
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
I thought I could use the SharedSizeGroup property in the <Grid> but it still doesn't resize correctly. Instead it only displays the <TextBlock> stretch across the <Grid>.
Here's my code:
<Grid Grid.IsSharedSizeScope="True" Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Labels" />
<ColumnDefinition Width="*" SharedSizeGroup="InputControls" />
</Grid.ColumnDefinitions>
<ItemsControl Grid.Row="1" ItemsSource="{Binding SelectedTemplate.Fields}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition SharedSizeGroup="InputControls"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}" Grid.Column="0" Margin="5"
VerticalAlignment="Center" Background="Red" />
<TextBox Text="{Binding Path=Value}" Grid.Column="1" Margin="5"
VerticalAlignment="Center" Background="Blue" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
Any idea how I can resolve this?
Thanks.
UPDATE1: I cannot get this to work as I need it to. This is what I've got so far:
<Grid Grid.Row="1" Background="Purple">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="Overall" />
</Grid.ColumnDefinitions>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels" Width="Auto" />
<ColumnDefinition SharedSizeGroup="InputControls" Width="*" />
</Grid.ColumnDefinitions>
<ItemsControl ItemsSource="{Binding SelectedTemplate.Fields}"
Background="Yellow"
Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Background="Green">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition SharedSizeGroup="InputControls"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}"
Grid.Column="0"
Margin="5"
VerticalAlignment="Center"/>
<TextBox Text="{Binding Path=Name}"
Grid.Column="1"
Margin="5"
VerticalAlignment="Center"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
This ends up displaying my layout this way:
As you can see, my TextBox are correctly aligned based on the largest TextBlock but my ItemsControls is not stretched all the way across. I guess that makes sense as it is within the same grid where the ColumnDefinitions are defined.
Now, if I move the ColumnDefinitions' out this grid to the outer grid and remove all instances ofGrid.IsSharedSizeScope`, I guess the following:
Which once again is closer to what I need as my ItemsControl is now stretching all the way as I've set its Grid.ColumnSpan="2" and my TextBox are still aligned to the TextBlock and are stretching all the way across but the problem now is that the TextBlock should be smaller as the Column is set to Auto but they appear to behave as if the column was set to * and I guess I'm losing the purpose of using IsSharedSizeScope since it has been removed.
Now if I add IsSharedSizeScope="True" to the outer grid, I get the following result:
Again, this is close to what I want as my ItemsControl is stretched, my textboxes are also stretch but they are no longer aligned to the largest TextBlock.
Finally, if I add Grid.IsSharedSizeScope="True" to ItemsControl as originally suggested by #mm8,
<Grid Grid.Row="1" Background="Purple" Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels" Width="Auto" />
<ColumnDefinition SharedSizeGroup="InputControls" Width="*" />
</Grid.ColumnDefinitions>
<Grid Grid.ColumnSpan="2" >
<ItemsControl ItemsSource="{Binding SelectedTemplate.Fields}"
Background="Yellow"
Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Background="Green">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition SharedSizeGroup="InputControls"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}"
Grid.Column="0"
Margin="5"
VerticalAlignment="Center"/>
<TextBox Text="{Binding Path=Name}"
Grid.Column="1"
Margin="5"
VerticalAlignment="Center"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
<!--<TextBlock Text="Invoice Number" Grid.Column="0" Margin="5" VerticalAlignment="Center"/>
<TextBox Text="InvoiceNumber" Grid.Column="1" Margin="5" VerticalAlignment="Center"/>-->
</Grid>
I get the following:
Which brings me back to square one, though the definitions are different?
I need to achieve the following:
What am I doing wrong??
Thanks.

Try to set the Grid.IsSharedSizeScope property of the ItemsControl itself:
<ItemsControl Grid.Row="1" ItemsSource="{Binding SelectedBarcodeTemplate.Fields}"
Grid.IsSharedSizeScope="True">
Synchronizing the width of elements in an ItemsControl: https://joshsmithonwpf.wordpress.com/2008/09/06/synchronizing-the-width-of-elements-in-an-itemscontrol/

I eventually found the answer in the following article: WPF Tutorial - Grid Panel under the section: "How to share the width of a column over multiple grids".
As per article:
Columns and rows that participate in size-sharing do not respect Star sizing. In the size-sharing scenario, Star sizing is treated as Auto. Since TextWrapping on TextBlocks within an SharedSize column does not work you can exclude your last column from the shared size. This often helps to resolve the problem.
So my final XAML looks like this:
<Grid Grid.Row="1" Background="Purple" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels" Width="Auto" />
<ColumnDefinition SharedSizeGroup="InputControls" Width="*" />
</Grid.ColumnDefinitions>
</Grid>
<ItemsControl ItemsSource="{Binding SelectedBarcodeTemplate.Fields}"
Background="Yellow"
Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Background="Green" ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}"
Grid.Column="0"
Margin="5"
VerticalAlignment="Center"/>
<TextBox Text="{Binding Path=Name}"
Grid.Column="1"
Margin="5"
VerticalAlignment="Center"
HorizontalAlignment="Stretch"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
And the outcome now finally looks correct:
Hope this helps others!

Windows 8.1, XAML binding listview but not showing the first item

Below is my code
<ListView ScrollViewer.VerticalScrollMode="Disabled" ScrollViewer.VerticalScrollBarVisibility="Hidden" HorizontalAlignment="Stretch" VerticalContentAlignment="Stretch" VerticalAlignment="Stretch" SelectionMode="None" Grid.Row="3" Grid.ColumnSpan="3" CanReorderItems="False" CanDragItems="False" IsRightTapEnabled="False" IsItemClickEnabled="True" BorderBrush="White" Background="White" ItemClick="lvGroupInfoCVS_ItemClick" RequestedTheme="Light" FontFamily="Helvetica" x:Name="lvGroupInfoCVS" ItemsSource="{Binding Source={StaticResource MyCollection}}">
<ListView.ItemTemplate>
<DataTemplate>
<Grid Width="{Binding ElementName=lvGroupInfoCVS, Path=ActualWidth}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="4*"/>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" FontFamily="Helvetica" Grid.Column="0" Text="{Binding Name}" Foreground="DarkGray" FontSize="23" HorizontalAlignment="Left"/>
<TextBlock Grid.Row="0" FontFamily="Helvetica" Grid.Column="1" Text="{Binding EventDate}" Foreground="DarkGray" FontSize="23" HorizontalAlignment="Center"/>
<TextBlock Grid.Column="2" FontFamily="Helvetica" Grid.Row="0" Text="{Binding StartTime}" Foreground="DarkGray" FontSize="23" HorizontalAlignment="Center"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
All my data shows up properly but my first item is blank, although it is clickable. I tried changing the width and height but I still have the same issue
Environment: Windows 8.1, XAML, C#
I tried looking into the other similar stackoverflow questions but had no luck

I had the same problem and I just fixed it!
Both of us tried to set Grid Width by binding to ListView.ActualWidth, but it's not working until first element will be rendered, so first elemnt always have 0 Width :(
To solve this, please do this (based on this answer by #Kievic
Setting the ListView.ItemContainerStyle with a
HorizontalContentAlignment setter makes the trick.
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>

You can do:
<ListView SelectedIndex="0">
If you want it to select the first item in the list on load.

how to manage tile usercontrols(having listbox binding) in MVVM model?

//this is usercontrol code
<ListBox Name="OvernightAverageListBox" ItemsSource="{Binding Path=OvernightAverageCollections}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Name="items" Background="{Binding BackColor}" Height="200" Width="200">
<TextBlock Height="46" HorizontalAlignment="Left" Margin="26,10,0,0" Name="currentRate" Text="{Binding Current_rate}" VerticalAlignment="Top" FontSize="36" />
<TextBlock Height="22" HorizontalAlignment="Left" Margin="26,20,0,0" Name="rate_difference" Text="{Binding RateChange_Value}" VerticalAlignment="Top" FontSize="20" />
<TextBlock Height="30" HorizontalAlignment="Left" Margin="26,30,0,0" Name="productName" Text="{Binding Product_name}" VerticalAlignment="Top" FontSize="24" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
//this is binding code on view
<controls:PanoramaItem Header="Overnight Average" Tap="RateTile_Tap">
<Grid x:Name="overnightAverage">
<views:OvernightAverageTileControl x:Name="eventsView"> </views:OvernightAverageTileControl>
</Grid>
</controls:PanoramaItem>
</ListBox>
now acoording to my code the tiles are coming vertically means each tile is taking in one row.
but i want them to come both horizontally and vertically means two tiles in each row.
plz share ur suggetion i am new to xaml designing.
first image shows wat i am getting.
second image is wat i want.
thanks :)

You could replace the StackPanel in your DataTemplate by a Grid:
<DataTemplate>
<Grid Name="items" Background="{Binding BackColor}" Height="200" Width="200">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Text="{Binding Current_rate}" ... />
<TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding RateChange_Value}" ... />
<TextBlock Grid.Column="0" Grid.Row="1" Text="{Binding Product_name}" ... />
</Grid>
</DataTemplate>
You may also specify absolute or relative widths of the columns and heights of the rows by setting the ColumnDefinition.Width and the RowDefinition.Height properties.

I have done it successfully using WrapPanel in toolkit oct 2011.
