How do I make my middle column take up the full width available while allowing space for the comment section so that all those comment boxes are nicely aligned to the right:
<DataTemplate x:Key="ActivityStreamItemTemplate">
<StackPanel VerticalAlignment="Top" Margin="5,0,0,0">
<Button Command="{Binding Path=DataContext.LoadSpacesCommand, ElementName=OrganisationList}" CommandParameter="{Binding}" Padding="-5,0,-5,-5" Margin="-7,-12,-7,-7" Height="auto" BorderThickness="0" HorizontalAlignment="Left" VerticalAlignment="Stretch" HorizontalContentAlignment="Left" UseLayoutRounding="True" FontSize="0.01">
<Grid Height="auto">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="67" />
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="60" />
</Grid.ColumnDefinitions>
<StackPanel Height="auto" Grid.Column="0" Background="Transparent">
<Border Background="Transparent" BorderThickness="0" Width="62" Height="62" HorizontalAlignment="Left" Margin="0,0,0,5">
<Image Source="{Binding created_by.image.link}" Width="62" Height="62"></Image>
</Border>
</StackPanel>
<StackPanel Height="auto" Grid.Column="1">
<TextBlock Text="{Binding type}" HorizontalAlignment="Left" FontSize="30" VerticalAlignment="Center" Margin="0,0,0,5" Foreground="White" />
<TextBlock Text="{Binding ttitle}" HorizontalAlignment="Left" FontSize="15" VerticalAlignment="Center" Margin="0,0,0,5" Foreground="White" TextWrapping="Wrap"/>
<TextBlock Text="{Binding created_by.name}" HorizontalAlignment="Left" FontSize="11" VerticalAlignment="Center" Margin="0,0,0,5" Foreground="White" />
</StackPanel>
<StackPanel Height="60" Grid.Column="2" Margin="10,0,0,0">
<StackPanel.Background>
<ImageBrush Stretch="Fill" ImageSource="/Assets/Icons/CommentsIcon.png"/>
</StackPanel.Background>
<TextBlock Text="{Binding comments.Count}" HorizontalAlignment="Center" FontSize="20" Foreground="Black" TextAlignment="Center" Padding="0,8,0,0"/>
</StackPanel>
</Grid>
</Button>
</StackPanel>
</DataTemplate>
I tried placing horizontal align on the third stackpanel but that actually didn't work.
EDIT: Thanks for the tries but no cigar:
You need to alter the style of the ListBoxItem
itself to ensure that the content is stretched across the available width.
Define this style:
<Style x:Key="ListBoxItemStyle" TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="HorizontalAlignment" Value="Stretch" />
</Style>
Then the Right alignment of the "Comments" image will work and the central text box will stretch to fill the available space.
You might find that just using a StackPanel
with an horizontal orientation works better than a Grid
for the item template, especially if the data in columns 0 and 2 are a constant width.
Play around with the space given for the columns, for example:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="67" />
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
This gives the center column 3 times more space than the right column
It's hard to tell exactly what you want because of how you've blurred your image. But I think the key is to make the container of the grid take up all available space, HorizontalAlignment="Stretch"
.
<DataTemplate>
<StackPanel HorizontalAlignment="Stretch">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="67" />
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="60" />
</Grid.ColumnDefinitions>
<!-- items here -->
</Grid>
</StackPanel>
The item you set to have Grid.Column="0"
will have width 67dip, the one with Grid.Column="2"
will be width 60dip, and the one with Grid.Column="1"
will fill up the rest of the space.
dip = device independent pixels - all Windows Phone apps are measured as if the screen is 480x800 and then rendered at the actual resolution of the screen.
Inside a StackPanel you can't do HorizontalAlignment to right while its orientation is LeftToRight, as far as I know. Avoid using it.
The problem stems from using a StackPanel as the top-most UIElement. Use a Grid instead and follow the rest of this advice: Right align content in ListBox
Which leads to this answer as well: C# windows phone -Alignment in xaml ListBox.ItemTemplate
Your problem is the Button, if it's not mandatory try deleting it and add a "Tap" Event to the StackPanel, i've tried it and it works.
<DataTemplate x:Key="ActivityStreamItemTemplate">
<StackPanel Tap="...">
// no <Button> here
<Grid>
---
</Grid>
// no </Button> here
</StackPanel>
</DataTemplate>
better option
<DataTemplate x:Key="ActivityStreamItemTemplate">
<Grid Tap="...">
...
</Grid>
</DataTemplate>
