I have a list box in expander:
<ListBox ItemsSource="{Binding MySource">
<ListBox.ItemTemplate>
<DataTemplate>
<RadioButton Content="{Binding MyContent}" />
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
I wrap the radio button with horizontal orientation stackpanel. I want the overflow radio buttons move down like right image shown below (no horizontal scrollbar). Now, mine is like the left one.

You need to use a WrapPanel, not a StackPanel. In WPF it's built into the main assemblies but in Silverlight you'll need to get the Silverlight Toolkit.
<ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled" ItemsSource="{Binding MySource">
<ListBox.ItemTemplate>
<DataTemplate>
<RadioButton Content="{Binding MyContent}" />
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<t:WrapPanel />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>

I want to display several images in a vertical scrolling list, but these images are subdivided into several groups that must be distiguishable by the user. To achive this, I use a ListView which items contain a WrapPanel, which contains the single images:
<ListView Name="ListGroups" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Label Content="{Binding Groupname}" />
<ListBox ItemsSource="{Binding Images}" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Image Source="{Binding Thumb}" />
<Label Content="{Binding Res}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
What I get is:
Current result - wrong
but what I want to achive is:
Thats what I want
That is to say I dont want any horizontal Scollbars at all, and the groups clearly must be separated. On the other hand, when sizing the window, the images within one group must wrap to fill all available space.
Just also disable the horizontal ScrollBar of the inner ListBox, and set Stretch="None" on the Image element.
<ListView ... ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<Label Content="{Binding Groupname}"/>
<ListBox ItemsSource="{Binding Images}"
ScrollViewer.HorizontalScrollBarVisibility="Disabled" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<Image Source="{Binding Thumb}" Stretch="None"/>
<Label Content="{Binding Res}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I would like to have GridSplitter-like functionality in a WPF ListBox (or ItemsControl). The following code doesn't work but demonstrates what I want to achieve:
<ListBox ItemsSource="{Binding MyCollection}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<TextBlock Text="{Binding MyTextProperty}" Margin="0,0,10,0"/>
<GridSplitter
Width="5"
Background="Red"
HorizontalAlignment="Right"
ResizeBehavior="CurrentAndNext"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Does anyone have an idea on how to implement this?
Why not use ListView GridView? GridView supports resizing columns.
I want to show in WrapPanel a list of images. How can I do that or maybe I shall use other control ?
You can absolutely use the WrapPanel to show a list of images, scrolling vertically or horizontally. To get the kind of panoramic tile effect like in People hub with your images, you could do something like this:
<controls:PanoramaItem Header="something" Orientation="Horizontal" Margin="0,-15,0,0" >
<ListBox Name="SomeList" Margin="0,0,-12,0" ItemsSource="{Binding SomeItemsList}" >
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel x:Name="wrapPanel" Width="700" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<Image Height="200" Width="200" Margin="12,0,9,0" Source="{Binding ImageURL}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</controls:PanoramaItem>
Please note that a WrapPanel inside a ListBox does pick up the DataTemplate you define .. so you have complete liberty to bind any list to your WrapPanel.
Hope this helps!
Search for the same thing and came across this: Displaying a Collection of Items in a WrapPanel.
<ItemsControl ItemsSource="{Binding ActorList}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Image Source="{Binding Image}" Height="100"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
or you can use Xceed's SwitchPanel.
Yes definetly not the WrapPanel, it has not ItemsSource, it can't take a list.
Use the ListBox, and you can set the ItemsSource.
Edit
I have WrapPanel where I want the control inside of it to go horizontally and centered, but when I have a listbox or a ItemsControl those elements just go downwards.
<toolkit:WrapPanel>
<ItemsControl x:Name="AnswerListBox" ItemsSource="{Binding Answers}" ScrollViewer.VerticalScrollBarVisibility="Disabled" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- those don't wrap horizontally and go downwards -->
<local:spriteToggleButton Text="{Binding text}" Selected="{Binding selected}" Sprites="{Binding Path=DataContext.UISprites, ElementName=questionField}" IsChecked="{Binding selected, Mode=TwoWay}" GroupName="{Binding Path=DataContext.QuestionTitle, ElementName=questionField}" ClickMode="Press" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</toolkit:WrapPanel>
I came across some similar issues and found out about ItemsPanel, so I tried that but it wrap but only to Content and didn't display the rest of the control inside of it.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
I take it that ItemsPanel is telling the ItemsControl which control to wrap it with but then it seems to ignore the rest of my datatemplate.
Joseph,
Slightly shooting in the dark here; but this is how I have used the WrapPanel (not through the ItemControl).
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Width="700" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
....
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Essentially the Listbox's ItemsPanel tells it to use the WrapPanel and then you could have anything you need in the DataTemplate. Note that the width is important as it tells the WrapPanel where to start wrapping.
Does this help?
I'm trying to write a WPF application for displaying images from a selection.
I want to display all of the available images in a banner along the top of the window, and display the main selected image in the main window for further processing.
If I wanted the list on the Left of the window, displaying the images vertically, I can do this quite elegantly using databinding.
<ListBox
Name="m_listBox"
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<Image Source="{Binding}" Width="60" Stretch="Uniform" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Is there a straightforward way I can make this horizontal instead of vertical?
The main requirements of a solution is:
The items are populated using databinding
The selected item is changed simply by the user clicking it.
WrapPanel
<ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBoxItem>listbox item 1</ListBoxItem>
<ListBoxItem>listbox item 2</ListBoxItem>
<ListBoxItem>listbox item 3</ListBoxItem>
<ListBoxItem>listbox item 4</ListBoxItem>
<ListBoxItem>listbox item 5</ListBoxItem>
</ListBox>
WPF Tutorial
The default ItemsPanel for the ListBox control is a VirtualizingStackPanel, so if you want the normal, default experience for the control but just have it laid out horizontally, you should specify this (and change the orientation).
Example:
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<VirtualizingStackPanel IsItemsHost="True" Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
Here is example of StackPanel.
Horizontal Breadcrumb with Mvvm binding
<ItemsControl
x:Name="tStack"
Grid.Row="1"
Grid.Column="0"
Height="40"
Background="Red"
ItemsSource="{Binding BreadCrumbs}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button
Margin="5"
CommandParameter="{Binding .}"
Command="{Binding BreadcrumbClickCommand, RelativeSource={RelativeSource AncestorType=ItemsControl}, Path=DataContext.BreadcrumbClickCommand}"
Content="{Binding Name}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
