The ItemContainerStyle is applied to the elements generated by the ItemsControl: ContentPresenter. The ContentPresenter will in turn contain whatever you put in your ItemTemplate. In the case of a ListBox, the ItemContainerStyle is applied to the generated ListBoxItem. The AlternationCount is, based on what you posted, only available on these generated items. You cannot use … Read more
You’re on the right track. You just need to create a Style and apply it to the ItemsControl.ItemContainerStyle. Then, in the style, specify a setter for the Grid.Row and Grid.Column. The ItemContainerStyle will get applied to the containers generated for each item.
A solution similar to Seb’s but probably with better performance : for(int i = 0; i < itemsControl.Items.Count; i++) { UIElement uiElement = (UIElement)itemsControl.ItemContainerGenerator.ContainerFromIndex(i); }
You might want to take a look at the ItemsPanel property: Gets or sets the template that defines the panel that controls the layout of items. Example: <ItemsControl> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> And you can set it in a Style as follows: <Style TargetType=”ItemsControl”> <Setter Property=”ItemsPanel”> <Setter.Value> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </Setter.Value> … Read more
Say I have an ItemsControl. I want to use a custom panel that swoops items in and out as you scroll; its called a SwoopPanel. Now, how do I tell the ItemsControl to use my SwoopPanel to contain the templates it creates? The quick way is to set the ItemsPanel on the ItemsControl: <ItemsControl.ItemsPanel> <ItemsPanelTemplate> … Read more
Check here http://www.codeproject.com/Articles/35886/WPF-ItemsControl-with-alternating-items-and-hover-.aspx You have to change your code like this to get it working <ItemsControl ItemsSource=”{Binding DataList}” AlternationCount=”2″> <ItemsControl.ItemTemplate> <DataTemplate> <Grid x:Name=”FooBar” Margin=”0,0,0,10″> —————————- —————————- </Grid> <DataTemplate.Triggers> <Trigger Property=”ItemsControl.AlternationIndex” Value=”0″> <Setter Property=”Background” Value=”Blue” TargetName=”FooBar”/> </Trigger> <Trigger Property=”ItemsControl.AlternationIndex” Value=”1″> <Setter Property=”Background” Value=”Red” TargetName=”FooBar”/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ItemsControl.ItemTemplate>
For those who are still looking for the right solution to this problem here is the one below.

<ItemsControl ItemsSource=”{Binding Numbers}”> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <!– could use a WrapPanel if more appropriate for your scenario –> <StackPanel Orientation=”Horizontal”/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation=”Horizontal”> <TextBlock x:Name=”commaTextBlock” Text=”, “/> <TextBlock Text=”{Binding .}”/> </StackPanel> <DataTemplate.Triggers> <DataTrigger Binding=”{Binding RelativeSource={RelativeSource PreviousData}}” Value=”{x:Null}”> <Setter Property=”Visibility” TargetName=”commaTextBlock” Value=”Collapsed”/> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I arrived at your question because I … Read more
You could have them semi-colon delimited in a single value, e.g. App.config <add key=”paths” value=”C:\test1;C:\test2;C:\test3″ /> C# var paths = new List<string>(ConfigurationManager.AppSettings[“paths”].Split(new char[] { ‘;’ }));
The attached properties only work on direct children of the Canvas. ItemsControl will place ContentPresenter controls as its direct children, so you might want to add a style for that as well: <ItemsControl ItemsSource=”{Binding Path=Nodes}”> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Canvas /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemContainerStyle> <Style TargetType=”ContentPresenter”> <Setter Property=”Canvas.Left” Value=”{Binding Path=XPos}” /> <Setter Property=”Canvas.Top” Value=”{Binding Path=YPos}” /> </Style> … Read more
