I have a list view that will contain notes that I input. I am having trouble figuring out how to have the list view item look how I want it to.
Below is how it should look:
And this is what it currently looks like:
How do I write the list view item in XAML so that the Date and time appear to the very top-right of each list view item, with the text of the note to the left?
<ListView x:Name="list" ItemsSource="{Binding Note}" BorderBrush="{x:Null}" BorderThickness="0">
<DataTemplate>
<ListViewItem>
<StackPanel Orientation="Horizontal">
</StackPanel>
</ListViewItem>
</DataTemplate>
</ListView>
Any help at all is much appreciated!
You are missing a number of elements required in order to get your screen to look the way you want.
You need to define the ItemTemplate for the ListView. You're on the right track here, it is a DataTemplate declared in XAML, you just have to apply it to the ListView.ItemTemplate property.
You need to set the HorizontalContentAlignment of the ListView to Stretch (the default is Left, which means your items will not fill the entire content area).
You need to use a DockPanel (or other similar panel) inside your DataTemplate to place your date content on the right, and the remainder of your content on the left.
You need to disable Horizontal Scrolling (ScrollViewer.HorizontalScrollBarVisbility) on the ListView in order to make your content wrap (otherwise it will just happily draw it all on one line).
I've included a sample ListView that should get you started.
<ListView
ItemsSource="{Binding Items}"
HorizontalContentAlignment="Stretch"
ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListView.ItemTemplate>
<DataTemplate>
<DockPanel>
<TextBlock
TextWrapping="Wrap"
Text="{Binding Date}"
Background="Magenta"
DockPanel.Dock="Right" />
<TextBlock Text="{Binding Content}" Background="Lime" />
</DockPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

I have this template (c# windows univeral app w8.1)
<ListView ItemsSource="{Binding SelectedSongStanzas}">
<ListView.ItemTemplate>
<DataTemplate>
<ListView ItemsSource="{Binding Verses}">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel HorizontalAlignment="Left">
<TextBlock Padding="0" Text="{Binding Harmonization2}" FontFamily="Lucida Console" FontSize="16" Foreground="BlueViolet" VerticalAlignment="Bottom"/>
<TextBlock Padding="0" Text="{Binding OriginalText}" FontFamily="Lucida Console" FontSize="16" VerticalAlignment="Top"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
And This is how it look
If see at image the first list view item shows the first ListItem lines are together with no spaces between them, but the second line shows a big gap between them.
Note:
1) I'm ,was trying with Grid instead stackpanel but looks same way.
2) If Try fixed height texts could be cut.
What can i do to force all ListItems looks the same way?
(Just Like the firs Item)
EDIT ONE: Based on the comments think the problem could be the default styles from windows universal app template. And now could be another question.
How to edit / change / Override those styles on that template ?
Finally as #AnjumSKhan post, the problem wasn't at XAML code, just my structure Has a Literal char \n
Something like this "some text here" was stored as => "\nsome text here", just i remove those new lines literals an now all looks as must be.
I have these controls:
<StackPanel>
<TextBlock Text="Bill Benson"/>
<Image Source="/Assets/Images/BB.png"/>
<ListBox>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text=""/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<TextBlock Text="ends: 2015"/>
</StackPanel>
ListBox may have any number of items inside it. I want the whole page scroll from top to bottom, but it doesn't scroll down-up. How can I do that? I know the problem is because a scrollable control inside another scrollable one, but don't know how to fix it.
You need to assign the height to the listbox control, as it is taking an auto which means that the height keeps on increasing according to the count of items in it, so its impossible to access the items in the bottom of the control, So either give it a height or instead of stackpanel keep it in a grid with row definitions.
<StackPanel>
<TextBlock Text="Bill Benson"/>
<Image Source="/Assets/Images/BB.png"/>
<ListBox Height="200">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text=""/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<TextBlock Text="ends: 2015"/>
</StackPanel>
Try specifying a height for your controls, especially StackPanel and ListBox, even just an "Auto" Height could work for testing. Also, rather than setting an ItemTemplate, which would be more useful if you had a List of items to bind the ListBox to, try some hardcoded values:
<ListBox>
<TextBlock Text="1"/>
<TextBlock Text="Test"/>
<TextBlock Text="Another"/>
<TextBlock Text="testing"/>
<TextBlock Text="Sample"/>
</ListBox>
Try to add more than the ListBox can show, and see if it scrolls.
Try a dock panel instead:
<DockPanel>
<StackPanel DockPanel.Dock="Top">
<TextBlock Text="Bill Benson"/>
<Image Source="/Assets/Images/BB.png"/>
</StackPanel>
<TextBlock DockPanel.Dock="Bottom" Text="ends: 2015"/>
<ListBox>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text=""/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</DockPanel>
The ListBox will automatically expand to fill the space. Note: It has to be the last child in the DockPanel. (You can change this functionality using LastChildFill="False")
I have an ItemsControl nested inside a ListBox.ItemTemplate. The top ListBox is data-bound to an ObservableCollection. The collection is essentially a Purchase which contains Formulae which in turn contain individual products.
Now, if an individual product inside a formula is clicked, I would like it to be deleted from its formula. So, in the event handler, I should be able to determine the product's position using:
var index = [theItemsControl].ItemContainerGenerator.IndexFromContainer((sender as Button).TemplatedParent);
However, in my event handler, I do not how how to find the containing ItemsControl. I cannot give it a fixed name, since it is itself a part of a ListBox.ItemTemplate, meaning there will be multiple instances.
This is my XAML, stripped of any style-related stuff:
<ListBox x:Name="lbBasketFormulae" ItemsSource="{Binding Path=Purchase.Formulae}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<!-- Formula Title -->
<StackPanel Orientation="Horizontal">
<Label Width="30" Content="{Binding Path=Quantity}"></Label>
<Label Content="{Binding Path=FormulaType, Converter={StaticResource formulaTypeToNameConverter}}"></Label>
</StackPanel>
<!-- Formula Products -->
<ItemsControl ItemsSource="{Binding Path=Products}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button x:Name="bnBasketFormulaProduct" HorizontalContentAlignment="Left" Content="{Binding Path=Name}" Click="bnBasketFormulaProduct_Click">
<Button.Template>
<ControlTemplate TargetType="Button">
<TextBlock Text="{TemplateBinding Content}" />
</ControlTemplate>
</Button.Template>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
So, my question is: How do I find the position of my product inside my formula and the position of that formula inside the purchase, so that I can remove it from the ObservableCollection? (Changing the collection should then automatically reflect to the UI since it is data-bound.)
Many thanks in advance for any advice or hints!

It is true that you should be able to do it via the viewmodel. But if you want you could use:
VisualTreeHelper.GetParent(myUserControl);
The answer is you don't find any positions of anything using ItemContainerGenerator.IndexFromContainer. Your problem is clearly taking place inside ViewModel and therefore you should seek for selected item or whatever inside your ViewModel and not in ListBox or code behind of Window.
Therefore I suggest you to create a proper ViewModel with proper Bindings.
I´m filling a listbox with a specific data, the code works fine, but I need to add a scrollviewer to the listbox because there are many elements inside, I tried to use a ScrolViewer and put inside the listbox, but doesn't work, here is the code
<StackPanel x:Name="Sites" Grid.Row="1" Orientation="Vertical">
<ListBox x:Name="ListSites" >
<ListBox.ItemTemplate>
<DataTemplate>
<Button Width="460" Height="120" Click="click" Name="btn">
<Button.Content>
<StackPanel Orientation="Vertical" Height="100" Width="460">
<TextBlock Width="460" Name="txtname" FontSize="22" Text="{Binding name}" Height="40" Foreground="CadetBlue" />
<TextBlock Width="460" Name="txtUrl" FontSize="22" Text="{Binding Url}" Height="60"/>
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
I fixed it, simply adding the Height property in the ListBox control
If the ListBox is not given infinite space for height then it should automatically scroll when items overflow its boundaries. For instance, if the second Grid row outside your stackpanel has explicit or 'star' height set, the scrollbar in the listbox will show up automatically.

You shouldn't need to add a ScrollViewer to your ListBox. It will start scrolling when it runs out of room.
However, because you've put the ListBox inside a StackPanel it won't ever think it's run out of room because the StackPanel grows infinitely in the direction of it's orientation to accommodate its contents.
You'll need to use a different container for your ListBox.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
I want to show a list of "properties" in my application. A property is simply a name/value pair. The number of properties is dynamic.
The best way to do this? The only thing I can come up with is creating a ListView with an ItemTemplate. But then the items are selectable, and that's not what I want. If I make the list read-only, it becomes gray. Don't like that either.
Anyone has a better suggestion?
<ScrollViewer>
<ItemsControl ItemsSource="{Binding Properties}">
<ItemsControl.ItemTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name}"/>
<TextBlock Text="{Binding Value}"/>
</StackPanel>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
Use a Grid for ItemsControl.ItemsPanel with SharedSizeGroup if you want all items to line up nicely.
