How to set WrapPanel itemsource to list?

问题:

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!

Yes definetly not the WrapPanel, it has not ItemsSource, it can't take a list. Use the ListBox, and you can set the ItemsSource.

Search for the same thing and came across this: Displaying a Collection of Items in a WrapPanel.

<ItemsControl ItemsSource="{Binding ActorList}" Margin="20">
<ItemsControl.ItemTemplate>
    <DataTemplate>
        <Image Source="{Binding Image}" Height="100"/>
    </DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
    <ItemsPanelTemplate>
        <WrapPanel/>
    </ItemsPanelTemplate>
</ItemsControl.ItemsPanel>

or you can use Xceed's SwitchPanel.
