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>

I have a DataTemplate for an ItemsControl that outputs a Grid with some binded controls, and this works as expected.
However, I want the first column of the Grid to output a counter of each Grid made.
For example...
<DataTemplate x:Key="myDataTemplate">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="75" />
<ColumnDefinition Width="150" />
</Grid.ColumnDefinitions>
<TextBlock Text="X" /> <!-- I want a counter to go here -->
<TextBox Grid.Column="1" Text="{Binding Path=Name}" />
</Grid>
</DataTemplate>
I want that first TextBlock to display 1, 2, 3, 4, etc... as the DataTemplate outputs new Grids.
Any ideas on the best way to do that?
Thanks!
You can achieve this using AlternationCount and AlternationIndex of ItemsControl. Like,
<ItemsControl ItemsSource="{Binding Items}" AlternationCount="{Binding Items.Count}">
<ItemsControl.ItemTemplate>
<DataTemplate x:Key="myDataTemplate">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="75" />
<ColumnDefinition Width="150" />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=(ItemsControl.AlternationIndex), RelativeSource={RelativeSource TemplatedParent}}" />
<TextBox Grid.Column="1" Text="{Binding Path=Name}" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
This will give you 0 based index; you can use IValueConverter if any changes needed.
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 have 3 controls in a Grid.Row but how can I make them use the full width of the page?
This is my xaml:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="140" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Grid.Column="0"
Grid.Row="1"
Source="/Assets/image1.png"
Height="25"
Width="25" />
<TextBox Grid.Column="1"
Margin="10,0,0,0"
Text="{Binding InputText, Mode=TwoWay}"
BorderBrush="Black"
BorderThickness="2"
VerticalAlignment="Center">
</TextBox>
<Button Grid.Column="2"
BorderThickness="2"
HorizontalAlignment="Right"
Command="{Binding AddTextCommand}"
Margin="10,0,0,0">
<TextBlock x:Uid="ButtonText" />
</Button>
</Grid>
This is now the result:
As you can see it is aligned left, how can I make it use the full width?
You're code only shows 3 controls (Image, TextBox, Button), while your screenshot gives 4 controls. I suppose the full width control on top is missing, but that's no problem to answer the question.
If we break down your XAML, you have:
First column width Auto, filled with an image.
Second column width 140, filled with a TextBox
Third column width * (or the rest of the space), filled with a Button
On the button you have placed HorizontalAlignment="Right" (default is Left), in which you're saying: only use the space necessary and put the control on the right side. If you want to use the full width available, you have to use HorizontalAlignment="Stretch".
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="140" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Grid.Column="0"
Source="/Assets/image1.png"
Height="25"
Width="25" />
<TextBox Grid.Column="1"
Margin="10,0,0,0"
Text="{Binding InputText, Mode=TwoWay}"
BorderBrush="Black"
BorderThickness="2"
VerticalAlignment="Center">
</TextBox>
<Button Grid.Column="2" x:Uid="ButtonText"
BorderThickness="2"
HorizontalAlignment="Stretch"
Command="{Binding AddTextCommand}"
Margin="10,0,0,0" />
</Grid>
Note that I have also removed the TextBlock from the Button and move the x:Uid tag to the button. Simply use ButtonText.Content in your resources to have your button localized, there's no need to place a TextBlock in there.
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.
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!
