I'm trying to set my layout to appear as follows:
Using the following XAML:
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Name="txtSiteName" VerticalAlignment="Top" Width="auto"/>
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" Grid.Column="1" HorizontalAlignment="Right">
<tabs:TabItem Name="tabSettings" TabItemText="Settings"
TabItemImage="settings.png" Margin="5" />
<tabs:TabItem Name="tabDelete" TabItemText="Delete Site"
TabItemImage="delete.png" Margin="5" />
</StackPanel>
</Grid>
However, it's appearing as:
What do I need to do to get the images to align to the right, and have the text vertically aligned on the left?
Try This
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Name="txtSiteName" VerticalAlignment="Top" Width="auto"/>
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" Grid.Column="2" HorizontalAlignment="Right">
<tabs:TabItem Name="tabSettings" TabItemText="Settings"
TabItemImage="settings.png" Margin="5" />
<tabs:TabItem Name="tabDelete" TabItemText="Delete Site"
TabItemImage="delete.png" Margin="5" />
</StackPanel>
</Grid>
A parent container isn't stretching to fill the available space.
You can try
<Grid HorizontalAlignment="Stretch" >
<!-- etc -->
and, if that doesn't work, move up the tree until you find the element that's not stretching.
OP Edit in support of the correct answer:
It turns out this is correct - A parent container wasn't stretching to fill the space.
The parent container was the ListBox that I was inserting the items into.
Where before I had just this:
<ListBox Name="SiteListBox" Grid.Row="2" />
I changed it to the following to force the containing ListBoxItems to stretch:
<ListBox Name="SiteListBox" Grid.Row="2">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
Change the TextBlock's Vertical Alignment to Center.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Name="txtSiteName" VerticalAlignment="Center"/>
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" Grid.Column="1" HorizontalAlignment="Right">
<tabs:TabItem Name="tabSettings" TabItemText="Settings"
TabItemImage="settings.png" Margin="5" />
<tabs:TabItem Name="tabDelete" TabItemText="Delete Site"
TabItemImage="delete.png" Margin="5" />
</StackPanel>
</Grid>
And try switching your column definitions.

I created the following ListView to display some data (removed extraneous markup):
<ListView ItemsSource="{Binding NewYorkResidents}">
<ListView.Header>
<Style>
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
</Style>
</ListView.Header>
<ListView.HeaderTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Name" Grid.Column="0" />
<TextBlock Text="Address" Grid.Column="1" />
</Grid>
</DataTemplate>
</ListView.HeaderTemplate>
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Name}" Grid.Column="0" />
<TextBlock Text="{Binding Address}" Grid.Column="1" />
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Now I want to reuse this exact same ListView + markup in a different view, just with a different ItemsSource (though it will bind to the same data type).
What is the best way to reuse the ListView and just specifiy the ItemsSource? I'm hoping to be able to do something like this:
<ListView DataTemplate="MyTemplate" ItemsSource=<some new binding> />
and still have it show the ListView headers and Name and Address TextBlocks using data from the ItemsSource.
Making a ControlTemplate doesn't seem like the right thing because I am specifiying actual data in the list view also (such as binding to name and address).
Is there a better way to create some type of resource so I can reuse this?
Define the header template and item template in resource dictionary and add reference of them in your code. you can reuse this templates.
<DataTemplate x:Key="HeaderTemplate1">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Name" Grid.Column="0" />
<TextBlock Text="Address" Grid.Column="1" />
</Grid>
</DataTemplate>
<DataTemplate x:Key="ListViewTemplate1">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Name}" Grid.Column="0" />
<TextBlock Text="{Binding clothing1}" Grid.Column="1" />
</Grid>
</DataTemplate>
<ListView HeaderTemplate="{StaticResource HeaderTemplate1}" ItemTemplate="{StaticResource ListViewTemplate1}"/>

I have a TextBlock and TextBox controls inside StackPanel, and I need to stretch TextBox to resize by the parent size in UWP.
<StackPanel Grid.Column="0" Grid.Row="1" Orientation="Horizontal">
<TextBlock Text="Name:" VerticalAlignment="Center" Width="130" />
<TextBox VerticalAlignment="Center" HorizontalAlignment="Stretch" />
</StackPanel>
This not works.. Any ideas?
The problem is the stack panel will only stretch to the size of the child elements so in your example you will only see one Textblock of 130 pixels and you will not see the TextBox.
To get the functionality you desire you should use a grid with two columns one 130 pixels and the other being * to fill up the entire column space that is available.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="130"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="25"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="Name:" VerticalAlignment="Center" Width="130" />
<TextBox Grid.Row="0" Grid.Column="1"/>
</Grid>
I usually wrap a TextBlock and TextBox pair inside a DockPanel
<DockPanel Grid.Column="0" Grid.Row="1" >
<TextBlock Text="Name:"
VerticalAlignment="Center"
Margin="5"
/>
<TextBox VerticalAlignment="Center"/>
</DockPanel>
Edit
For UWP which doesn't have DockPanel:
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Grid Grid.Column="0" Grid.Row="1" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="Name:"
VerticalAlignment="Center"
Margin="5"
/>
<TextBox Grid.Column="1"
VerticalAlignment="Center" HorizontalAlignment="Stretch" />
</Grid>
</Grid>
I worked out a similar problem in UWP
<StackPanel Margin="{StaticResource SmallTopBottomMargin}" Orientation="Vertical">
<TextBlock Text="Project Name:" />
<TextBox /> <--full width
<TextBlock Text="Exported Template:" /> <--full width
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<TextBox /> <--max width - button width
<Button Grid.Column="1">...</Button>
</Grid>
I'm trying to create a listview that has column headers and the lists fields mimics the width of its corresponding header. No bindings fail but the textblocks width in the data template don't match up with their headers width. I'm guessing because the data template can't find the element. Any ideas to get this to work?
<Grid Grid.Column="1" Grid.Row="1" x:Name="listViewHeaders" Height="50" VerticalAlignment="Top" Margin="10,0" >
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<!--<controls:CustomGridSplitter/>-->
<TextBlock x:Name="nameHeader" Grid.Column="0" Text="Name" />
<TextBlock x:Name="typeHeader" Grid.Column="1" Text="Type" />
<TextBlock x:Name="colorHeader" Grid.Column="2" Text="Color" />
</Grid>
<ListView x:Name="ListView" Grid.Row="1" Grid.Column="1" Background="#FF494949" Margin="10,50,10,0" ItemsSource="{Binding CurrentCardList}">
<ListView.ItemTemplate>
<DataTemplate>
<Grid Width="{Binding ActualWidth, ElementName=ListView}">
<!--<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>-->
<StackPanel Orientation="Horizontal">
<TextBlock Grid.Column="0" Width="{Binding ActualWidth, ElementName=nameHeader}" Text="{Binding Name}" />
<TextBlock Grid.Column="1" Width="{Binding ActualWidth, ElementName=typeHeader}" Text="{Binding Type}" />
<TextBlock Grid.Column="2" Width="{Binding ActualWidth, ElementName=colorHeader}" Text="{Binding Color}" />
</StackPanel>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
</ListView>
The bindings work fine. But you're assuming that TextBlock elements in the header row will fill out the entire table cell, which they won't. They only fill as much space as much text they contain. In your case that's about 30px. You can find this information by using the Live Visual Tree feature of VS 2015.
You can solve the problem by wrapping the header TextBlock elements in another element that will fill out all available space, such as Border. Here's the solution:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid x:Name="listViewHeaders" Height="50" VerticalAlignment="Top" Margin="10,0" >
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<!--<controls:CustomGridSplitter/>-->
<Border Background="Blue" HorizontalAlignment="Stretch" Grid.Column="0" x:Name="nameHeader">
<TextBlock Text="Name" />
</Border>
<Border Background="Red" x:Name="typeHeader" Grid.Column="1">
<TextBlock Text="Type" HorizontalAlignment="Stretch" />
</Border>
<Border Background="Yellow" x:Name="colorHeader" Grid.Column="2">
<TextBlock Text="Color" HorizontalAlignment="Stretch" />
</Border>
</Grid>
<ListView x:Name="ListView" Background="#FF494949" Margin="10,50,10,0" ItemsSource="{Binding CurrentCardList}">
<ListView.ItemTemplate>
<DataTemplate>
<Grid Width="{Binding ActualWidth, ElementName=ListView}">
<!--<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>-->
<StackPanel Orientation="Horizontal">
<TextBlock Grid.Column="0" Width="{Binding ActualWidth, ElementName=nameHeader}" Text="{Binding Name}" />
<TextBlock Grid.Column="1" Width="{Binding ActualWidth, ElementName=typeHeader}" Text="{Binding Type}" />
<TextBlock Grid.Column="2" Width="{Binding ActualWidth, ElementName=colorHeader}" Text="{Binding Color}" />
</StackPanel>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
</ListView>
</Grid>
This will create the following effect, which I believe is what you're after.

I know how the columndefinition works in XAML but there is something I want to do and don't know how.
I want 4 columns like that:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="110" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="80" />
<ColumnDefinition Width="80" />
</Grid.ColumnDefinitions>
column has fixed width
column must take all the available space (yes it is between columns and this is exactly the problem)
column has fixed width
column has fixed width
The 2nd column contains text and the problem is that when that text is too short the 2nd column does not take all the available space. it get's smaller automatically and this for each row. I can make it work with this code in the textblock:
MinWidth="2000"
But it's not the good way since this number could be too low when the screen is big.
Here the whole listview containing the 4 columns:
<ListView Grid.Row="1" Grid.ColumnSpan="4" ItemsSource="{Binding blabla}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="110" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="80" />
<ColumnDefinition Width="80" />
</Grid.ColumnDefinitions>
<Image Height="110" Width="110" Grid.Column="0" Source="{Binding blabla}" HorizontalAlignment="Stretch" />
<TextBlock Text="{Binding blabla}" TextWrapping="Wrap" Margin="5,0,0,0" Grid.Column="1" FontSize="16" HorizontalAlignment="Stretch" TextAlignment="Left" FlowDirection="LeftToRight" MinWidth="2000" VerticalAlignment="Center" ScrollViewer.HorizontalScrollBarVisibility="Disabled" FontStretch="UltraCondensed"/>
<TextBlock Grid.Column="2" TextWrapping="Wrap" Foreground="Black" Margin="5,0,0,0" HorizontalAlignment="Stretch" VerticalAlignment="Center"/>
<Image Source="{Binding blabla, Converter={StaticResource ImgConverter}}" Grid.Column="3" Width="76" Height="76" HorizontalAlignment="Center" Stretch="None" VerticalAlignment="Center" Margin="0"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Your layout is well-defined but missed a small thing that is causing that the content of the Listviewitem is margined to the left because that is defined in the default ListViewItemStyle which is named "ItemContainerStyle" for the ListView Control .
All what you need to do is add this ListViewItemStyle that I've modified to stretch the content Horizontally and Vertically across all the available space for the item to your Resources
<Style x:Key="StretchedListViewItemStyle"
TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment"
Value="Stretch" />
<Setter Property="VerticalContentAlignment"
Value="Stretch" />
</Style>
Then set it as the ItemContainerStyle for the ListView as follows:
<ListView Grid.Row="1" Grid.ColumnSpan="4" ItemsSource="{Binding blabla}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" ItemContainerStyle="{StaticResource StretchedListViewItemStyle}"/>
Inside the same StackPanel I'd like to put a control aligned on the left and another one on the right side. I made an attempt using a Grid and defining ColumnDefinitions but with no luck.
<StackPanel Orientation="Horizontal">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="72" />
</Grid.ColumnDefinitions>
<StackPanel HorizontalAlignment="Left" Grid.Column="0" Orientation="Horizontal">
<Button />
</StackPanel>
<StackPanel HorizontalAlignment="Right" Grid.Column="1">
<Button Height="72" Width="72" />
</StackPanel>
</Grid>
</StackPanel>
The first column usually will take from 50% to 80% of the total width (depending on the content), while the second column will always take 72px. How can I set the first column so that it fills the total Grid width minus 72px?
Set the Width property of the first column to Star:
<ColumnDefinition Width="*" />
Making the change in your code should work:
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="72" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Horizontal">
<Button />
</StackPanel>
<StackPanel HorizontalAlignment="Right" Grid.Column="1">
<Button Height="72" Width="72" />
</StackPanel>
</Grid>
</StackPanel>
