XAML Grid Column Widths not matching - xaml

I am making a table in UWP (I am very new to UWP so go easy on me! Maybe even suggest a way that it is ten times better to implement this) that dynamically loads the data. This is the XAML code for it:
<ListView x:Name="ShiftListView" Grid.Column="0">
<ListView.HeaderTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" x:Name="HeaderColumn"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Location" Grid.Column="0"/>
<TextBlock Text="Role" Grid.Column="1"/>
<TextBlock Text="Date" Grid.Column="2"/>
<TextBlock Text="Start" Grid.Column="3"/>
<TextBlock Text="Finish" Grid.Column="4"/>
</Grid>
</DataTemplate>
</ListView.HeaderTemplate>
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Location}" Grid.Column="0"></TextBlock>
<TextBlock Text="{Binding Role}" Grid.Column="1"></TextBlock>
<TextBlock Text="{Binding Date}" Grid.Column="2"></TextBlock>
<TextBlock Text="{Binding Start}" Grid.Column="3"></TextBlock>
<TextBlock Text="{Binding Finish}" Grid.Column="4"></TextBlock>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The column definitions are done in the exact same way for both grids however the first one is the only one that stretches out to fill the entire available space but the other works as if I have inputted auto and only scaling to the size of the content. I have tried to bind the widths of the second set of columns to the first set but it doesn't change anything.
<ColumnDefinition Width="{Binding ElementName=HeaderColoumn, Path=ActualWidth"/>
But alas this did not work.
Here is a screenshot of the problem

Appending ItemContainerStyle to the ListView, specify HorizontalContentAlignment=Stretch.
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="Padding" Value="0"/>
</Style>
</ListView.ItemContainerStyle>

UWP - Can I bind a textblock in a datatemplate to a grid column's width outside of it?

Relatively new to UWP, is it possible to bind a TextBlock of a DataTemplate (used for ItemTemplate in a listview) to a column outside of it, or is there any way to set the DataTemplate's grid columns' widths to the size of the "MainGrid"'s column definition widths? Code below to show what I'm trying to achieve.
<Grid x:Name="MainGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="Column1" Width="*"/>
<ColumnDefinition x:Name="Column2" Width="8*"/>
<ColumnDefinition x:Name="Column3" Width="*"/>
</Grid.ColumnDefinitions>
<ListView Name="recordList" ItemsSource="{x:Bind _recordingList, TargetNullValue=0}">
<ListView.ItemTemplate>
<DataTemplate x:DataType="local:Recording">
<Grid>
<TextBlock Grid.Column="{Binding Column1}" Name="TextBlock_Time" Text="{x:Bind Time}"/>
<TextBlock Grid.Column="{Binding Column2}" Name="TextBlock_Message" Text="{x:Bind Message}"/>
<TextBlock Grid.Column="{Binding Column3}" Name="TextBlock_Type" Text="{x:Bind Type}"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
With the image below, I suppose imagine the red lines are the window. Essentially trying to get the columns to adapt to the window size changing.

I think you want listviewitem to be streched to the size of window. To achieve that you need to set HorizontalContentAlignment of listviewitem has to set to stretch in ItemContainerStyle
<ListView x:Name="MessagesList" BorderThickness="1" ItemsSource="{x:Bind _recordingList, TargetNullValue=0}" BorderBrush="Black">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter>
<Setter Property="Padding" Value="0"></Setter>
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate x:DataType="local:Recording">
<Grid BorderThickness="0,1,0,0" Padding="20" BorderBrush="{ThemeResource SystemControlForegroundBaseMediumBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="8*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{x:Bind Time,Mode=OneWay}"></TextBlock>
<TextBlock Grid.Column="1" Text="{x:Bind Message,Mode=OneWay}"></TextBlock>
<TextBlock Grid.Column="2" Text="{x:Bind Type,Mode=OneWay}"></TextBlock>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
You just need to move your columns to the template itself.
DataTemplate is a scheme that describes what and where. Because it's in ItemTemplate , then it means it's for every item.
<ListView Name="recordList" ItemsSource="{x:Bind _recordingList, TargetNullValue=0}">
<ListView.ItemTemplate>
<DataTemplate x:DataType="local:Recording">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="Column1" Width="*" />
<ColumnDefinition x:Name="Column2" Width="8*" />
<ColumnDefinition x:Name="Column3" Width="*" />
</Grid.ColumnDefinitions>
<TextBlock
Name="TextBlock_Time"
Grid.Column="0"
Margin="20"
Foreground="Red"
Text="{x:Bind Time}" />
<TextBlock
Name="TextBlock_Message"
Grid.Column="1"
Margin="20"
Foreground="Green"
Text="{x:Bind Message}" />
<TextBlock
Name="TextBlock_Type"
Grid.Column="2"
Margin="20"
Foreground="LightBlue"
Text="{x:Bind Type}" />
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
That should make your items look like this.
Check out documentation, as it's explaining it nicely. There are templates in templates. So you can template a Container (how it should display items), and Items (how every item should look like).
Templates
Remember about HorizontalAlignment="Stretch" etc. as this means that the textblock (or Grid) will occupy all of it's space available (horizontally). Tinker with it and you'll get a grasp on how it works.

Define listview in resource file with only ItemSource changing

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}"/>

How to align images to the right and text to the left?

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.

Grid alignment inside ComboBox selection

I'm trying to customize the content I display inside a combobox. The source that I have is the following for the combobox definition:
<ComboBox
x:Name="ServicesComboBox"
Margin="36,220,36,0"
VerticalAlignment="Top"
SelectionChanged="ComboBox_SelectionChanged"
ItemTemplate="{StaticResource MetricService}"
BorderBrush="#CC000000">
The itemtemplate I'm using is the following:
<UserControl.Resources>
<DataTemplate x:Key="MetricService">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding MetricsName}" FontSize="16"/>
<TextBlock Text="{Binding MetricsProvider}" Foreground="#FF878787"
FontSize="16" Grid.Column="2" HorizontalAlignment="Right"/>
</Grid>
</DataTemplate>
</UserControl.Resources>
The result is this image:
The problem happens when I click the combobox, and what I see is this:
Is there any way to solve this?
You need to set the HorizontalContentAlignment of items to Stretch like this:
<ComboBox x:Name="ServicesComboBox"
Margin="36,220,36,0"
VerticalAlignment="Top"
BorderBrush="#CC000000"
SelectionChanged="ComboBox_SelectionChanged"
ItemTemplate="{StaticResource MetricService}">
<ComboBox.ItemContainerStyle>
<Style TargetType="ComboBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ComboBox.ItemContainerStyle>
</ComboBox>

XAML - Can't resize elements to 0 width in this case

Given the following XAML my goal is to keep the columns AAA, BBB, CCC always visible. The columns with the listboxes can resize all the way to zero though.
If I remove the ListBoxes then the application works exactly the way I want it to. That is, it doesn't have the weird behavior where the min widths are not respected.
With the listboxes (or DataGrids) the following XAML has this behavior:
After starting the application, if I drag the splitterA all the way close to BBB (BBB will keep the desired width of 25), then drag the splitterB all the way to the right then AAA will have the desired width of 25.
On the other hand, after starting the application, if I drag splitterA all the way to the right (AAA will keep the desired width of 25), then drag the splitterB all the way to the right then AAA will go off the screen. Surprisingly if I then drag the splitterA just a pixel to the left then both columns will "snap" into the correct place.
<Grid Background="CadetBlue" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition />
<ColumnDefinition MinWidth="60"/>
</Grid.ColumnDefinitions>
<TextBlock Text="CCC" Width="25" />
<ListBox Grid.Column="1" />
<GridSplitter Width="5" Grid.Column="2" Name="splitterB" HorizontalAlignment="Left" />
<Grid Background="Aqua" Grid.Column="2" Margin="5,0,0,0" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition />
<ColumnDefinition MinWidth="30"/>
</Grid.ColumnDefinitions>
<TextBlock Text="BBB" Width="25" />
<ListBox Grid.Column="1" />
<GridSplitter Width="5" Grid.Column="2" Name="splitterA" HorizontalAlignment="Left" />
<Grid Background="BurlyWood" Grid.Column="2" Margin="5,0,0,0" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="AAA" Width="25" />
<ListBox Grid.Column="1" />
</Grid>
</Grid>
</Grid>
Why does it work when I remove the listboxes?
Note: I modified the question and XAML code slightly to clarify things and also to show what I just found about the listboxes.
I've been playing around with the code for a little bit and it looks like your main problem lies in the fact that your GridSplitters don't have their own columns.
The way GridSplitter works is it adjusts the column immediately to the left and immediately to the right of it. So simply adding an additional column for a GridSplitter won't quite cut it, since you will then have 4 columns in your Grid, and you need both columns to the left of the splitter to be affected. So I would recommend putting those in an additional Grid.
The other problem is the MinWidth of 50 you have on the outer grid does not account for the width of the GridSplitter, so it should be 55.
It seems like this whole thing could be done more cleanly, but since I'm not sure exactly what you're trying to accomplish, I kept the "spirit" of your code intact and updated some things:
<Grid Background="CadetBlue">
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="50" Width="Auto"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition MinWidth="55" Width="5*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="CCC" />
<ListBox Grid.Column="0"/>
<GridSplitter Width="5" Grid.Column="1" />
<Grid Background="Aqua" Grid.Column="2">
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="25"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition MinWidth="25" Width="5*" />
</Grid.ColumnDefinitions>
<TextBlock Text="BBB"/>
<ListBox Margin="0,20,10,20"/>
<GridSplitter Width="5" Grid.Column="1" />
<Grid Background="BurlyWood" Grid.Column="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="AAA" Width="25" />
<ListBox Margin="0,20,10,20" Grid.Column="1" />
</Grid>
</Grid>
</Grid>
Hope this helps!
