I am developing a WPF application.
have a list of user controls
<Grid >
<ListView ItemsSource="{Binding MyList}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" >
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Vertical" ItemWidth="{Binding (ListView.View).ItemWidth, RelativeSource={RelativeSource AncestorType=ListView}}"
MinWidth="{Binding ItemWidth, RelativeSource={RelativeSource Self}}"
ItemHeight="{Binding (ListView.View).ItemHeight, RelativeSource={RelativeSource AncestorType=ListView}}"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate >
<DataTemplate >
<Views:MyUserControl Height="auto" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" SnapsToDevicePixels="True"/>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
And MyUserControl has another list of user controls "DetailUserControl":
<UserControl x:Class="MyUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300" >
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="45" />
<RowDefinition />
</Grid.RowDefinitions>
<Border Grid.RowSpan="2" >
<StackPanel VerticalAlignment="Top" Orientation="Horizontal" HorizontalAlignment="Center" >
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Margin="10" Text="{Binding Title}" />
</StackPanel>
</Border>
<Border Grid.Row="1" Style="{StaticResource SummaryInnerFill}" >
<ItemsControl ItemsSource="{Binding DetailUserControls}" >
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</Border>
</Grid>
I used wrap panel to make all the usercontrols to be orderd from left to right one after the other.
I want the layout to be optimized and use as much as it can from the first line, and only then it will move to the second line.
here is an example (sorry for my drawing skills :) )
I have the following layout:
if I change the order inside the tiles I can have the following layout (that contains the same tiles but don't waste space an is much more organized):
Is there a panel I can use that will take care of it?
You can make use of Uniform Control Grid. You can specify Rows and Columns Properties. Controls are added to the grid in the order that they are declared.Its child controls are organised into a tabular structure of rows and columns. Unlike the Grid control, you don't have fine-grained control of the layout.
Example,
<UniformGrid Name="uniformGrid1"
Rows="2"
Columns="3">
<Button Content="blah"
Margin="2" />
<Button Content="blah1"
Margin="2" />
<Button Content="blah2"
Margin="2" />
</UniformGrid>

I have a Page that allow the user to load multiple images thumbnails from his folders.
The number of rows update nicely when the width of the window is changed
The only thing that I could not figure out how to make it work is having the vertical scroll bars, I pretty much tried every settings possible.
At first my root was a stackPanel so I switched to a Grid to see if there would be any difference.
here is my xaml
<Page
x:Class="IMG.Pages.UploadPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:local="using:IMG.Pages"
xmlns:Models="using:IMG.Models"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid x:Name="root">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0"
Padding="2"
BorderBrush="Black"
BorderThickness="1"
Orientation="Horizontal">
<Button Click="GetPhoto" Content="get images" />
</StackPanel>
<GridView x:Name="ImageGrid" Width="Auto" Background="LightBlue" Grid.Row="1" Margin="5" Height="Auto"
SizeChanged="ImageGridSizeChanged"
ScrollViewer.HorizontalScrollBarVisibility="Auto"
ScrollViewer.HorizontalScrollMode="Auto"
ScrollViewer.VerticalScrollBarVisibility="Disabled"
ScrollViewer.VerticalScrollMode="Disabled">
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid Orientation="Horizontal"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.ItemTemplate>
<DataTemplate x:Name="ImgThumbnail" x:DataType="Models:ImageData">
<StackPanel
Width="100"
Height="120"
Margin="5"
AutomationProperties.Name="{x:Bind Hash}">
<StackPanel Margin="1">
<TextBlock Text="{x:Bind File}" />
</StackPanel>
<Image x:Name="thumbIMG" Width="80" Height="100" Stretch="UniformToFill" />
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
At first the gridview is empty, the user click on the button and then in the FileOpenPicker he can choose multiple images and they are added as thumbnail binded to an ObservableList of ImageData
The binding work nicely, I am simply stuck on the scrollbar
I have experienced the same issue and I fixed it by setting the height of the gidview on the fix size instead of auto. And than you can set
ScrollViewer.VerticalScrollBarVisibility = "Visible"
ScrollViewer.VerticalScrollMode = "Enable"
I'm sorry if I didn't find any relative post/questions regarding my small annoying issue.
I have a WPF window with a DockPanel (LastChildFill = True) that hosts three controls :
One Button (OK)
One label (Title)
One Border with a listbox in it
What I do is when the test in process is "pass" it has no data to push in the listbox so I make it collapsed and then I would like the Title label to be centered in the available space that is not used by the listbox and its border.
When I have a "fail" or an "error", I have data to put in the listbox and then it is visible and everything is just as expected.
I tried many things before coming here and I lost enough time on this as I need to get other stuff done by the time I'm writing here.
Can anyone point me out how to solve my issue (centering label when listbox+border is collapsed) ?
Here is my xaml code for this window :
<Window x:Class="NI.TestStand.WPFControls.Views.DisplayBannerView"

</ListBox>
</Border>
</DockPanel>
</Border>
</Grid>
</Window>
Here are the images that shows a PASS and an ERROR to show the difference.
The PASSED title message in the green lime window should go in the middle of the window as the listbox is collapsed..
Thanks for all your help and time
I would design the whole thing like this:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Border BorderBrush="Black" BorderThickness="2"
Grid.RowSpan="{Binding PassErrorBooleanProperty, Converter={StaticResource BoolToRowSpanConverter}}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Label
x:Name="main_message"
Padding="15"
FontSize="50"
Content="MAIN_MSG"
DockPanel.Dock="Top"
HorizontalAlignment="Center"
VerticalContentAlignment="Center" />
<Border Grid.Row="1" BorderBrush="Chocolate" BorderThickness="2" Margin="10" Name="messages_border"
Visibility="{Binding PassErrorBooleanProperty, Converter={StaticResource BoolToVisibilityConverter}}">
<ListBox
Background="{Binding ElementName=DisplayBannerMessage, Path=Background}"
Foreground="Black"
ScrollViewer.HorizontalScrollBarVisibility="Auto"
ScrollViewer.VerticalScrollBarVisibility="Auto"
ScrollViewer.CanContentScroll="True"
VerticalContentAlignment="Top"
VerticalAlignment="Stretch"
x:Name="detail_message">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" ToolTip="{Binding}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Border>
<Button Grid.Row="2"
x:Name="butOK"
DockPanel.Dock="Bottom"
Margin="10" Content="OK"
HorizontalAlignment="Center"
VerticalAlignment="Top"
Padding="10" Width="150"
Click="butOK_Click" />
</Grid>
</Border>
</Grid>
There are two bindings to PassErrorBooleanProperty (which I've made up as something you'd use to indicate the result, you might have something else in place for this already), and you'd need two different converters, one for converting to a Visibility, and one for converting to an int (Grid.RowSpan).
When the value is true (Pass), you'd return Visibility.Collapsed and 2 from the converters. When the value is false, you'd return Visibility.Visible and 1.
Let me know if you need more info on the converters, though there is lots of information out there on using IValueConverter to create Boolean to Visibility converters, etc.
I read here some posts on that issue and still didn't found a solution to my problem, also I have used this guide.
My ListBox still showing as a long list with a ScrollViewer, and not Horizontally as I refer to.
XAML: EDITED!
<DockPanel LastChildFill="False" IsEnabled="{Binding IsWindowEnabled}" MinWidth="724" Background="Red">
<!-- save notifictaion popup -->
<Label DockPanel.Dock="Top" Margin="10" FontSize="15" Foreground="Green" Content="{x:Static ml:MultiLang._123}" x:Name="ML_0003" />
<StackPanel DockPanel.Dock="Top" Orientation="Horizontal" Margin="10 0">
<Label Content="Select Constant Type" Margin="0 0 10 0" />
<ComboBox Width="150" ItemsSource="{Binding ComboNames}" DisplayMemberPath="Value" SelectedValuePath="Key" SelectedValue="{Binding SelectedComboType}" />
</StackPanel>
<ListBox DockPanel.Dock="Top" BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Stretch" Margin="10" ItemsSource="{Binding Combos}" SelectedItem="{Binding SelecetedCombo}" ScrollViewer.CanContentScroll="False" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0 0 0 5">
<Label Content="{Binding Index}" Margin="10 0" Width="20" />
<TextBox Width="150" Margin="0" IsEnabled="{Binding IsEditable}" Text="{Binding Path=Value, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</DockPanel>
But Still my List Looks like that:
IMAGE: EDITED No.2
What I'm doing wrong?
Thank you very much!
Please try to change the ItemPanel from
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
To
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
Ignore the above suggestion.
EDIT
Could you please try to give a background color to internal stack panel you have used in DataTemplate? like
<DataTemplate>
<StackPanel Background="Blue" Orientation="Horizontal" Margin="0 0 0 5">
<Label Content="{Binding Index}" Margin="10 0" Width="20" />
<TextBox Width="150" Margin="0" IsEnabled="{Binding IsEditable}" Text="{Binding Path=Value, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" />
</StackPanel>
</DataTemplate>
It will give you an idea that how stackpanel is taking the space in ListBox items. Then we can try to adjust the width of each ListBoxItem

This is what I see on my side
and XAML is

The problem is that you set a width of 220 in your listbox, and since the items are in wrap panel, they will show vertically, try to increase the width
<ListBox Width="220" [OTHER PROPERTIES]>
Increase the width
<ListBox Width="520" [OTHER PROPERTIES]>
Or if your design allows it, delete the width property and let the listbox fill it's parent
By default, ListBox uses a panel called VirtualizingStackPanel to arrange its items
vertically.
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
I have a ItemsControl that displays a bunch of UserControl's inside of a WrapPanel. This works perfectly, unless I have a bunch of UserControls, and then the overflow is rendered off screen, and I can't access it. My goal is to have the WrapPanel wrap horizontally, but once the controls are off the screen, to present a scroll bar, and this seems to not work for me.
<ItemsControl ItemsSource="{Binding Servers, Mode=OneWay}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="1" Margin="5,5,5,5">
<local:ServerControl DataContext="{Binding }" /> <!-- The actual UserControl -->
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
When the application first starts, this is what it looks like. What you can't see if that there should be 14 boxes viewed. The WrapPanel is doing its job, but it's rendered outside of the bounds of the window.
This shows all the UserControls, but I had to expand the window to be able to see them all.
Any help would be greatly appreciated.

Change you second row height to *
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" /> <-- This is what you want -->
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
Setting a RowDefinition to Auto means it will calculate the cumulative DesiredHeight of all child elements in that row and assign it to the Height property of RowDefinition. So, as your WrapPanel grows, it will apply the height to that row and stretch out your parent Grid.
Hello I need a multicolumn control with variable heights and with expand/collapse capability. My approach so far is this-
<ListView Grid.Row="1" ItemsSource="{Binding MyCollection}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" Grid.IsSharedSizeScope="True" VerticalContentAlignment="Center">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel></WrapPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
<DataTemplate>
<control:UCNewsFeed Margin="6" DataContext="{Binding Post}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
please notice that UCNewsFeed is a usercontrol which is given below-
<Grid x:Name="MainGrid">
<Grid.RowDefinitions>
<RowDefinition Height="57"/>
<RowDefinition Height="auto"/>
</Grid.RowDefinitions>
<Grid x:Name="namePanel">
<StackPanel x:Name="nameContainer">
<TextBlock>Lamia Mehreen</TextBlock>
<TextBlock>Monday at 12:02pm</TextBlock>
<Button/>
</StackPanel>
</Grid>
<Border x:Name="hiddenPanel" Visibility="Collapsed" Grid.Row="1">
<StackPanel x:Name="editPanel" Orientation="Horizontal">
<RichTextBox/>
<Button Margin="0" Foreground="{x:Null}" Style="{DynamicResource ButtonStyle1}" BorderThickness="0" Background="{x:Null}" BorderBrush="{x:Null}" Focusable="False" HorizontalAlignment="Center" VerticalAlignment="Center" Padding="0" Width="37" Height="37"/>
</StackPanel>
</Border>
</Grid>
The layout is so far okay. The problem arises when "hiddenPanel"'s visibility is switched to visible from code behind. The entire row of the listview gets the height of the selected row.
I need to expand one cell only, NOT an entire row. Please suggest any approach that might come in handy. (I have simplified the XAML for easy reading, they might not look like the attached images)
