What exactly does Panel.IsItemsHost do?

由 偶尔善良 提交于 2019-12-03 18:51:48
问题 I cannot find any good documentation for the Panel.IstItemsHost attached property. I see plenty of examples of people setting it on the ItemsContainer template for an ItemsControl, but the un-documentation over at MSDN does not explain why or what advantages setting property confers. I have built plenty of containers that do NOT set this property, but have not yet noticed any ill effects. 回答1: Say I have an ItemsControl. I want to use a custom panel that swoops items in and out as you scroll;

Is there an ItemsControl equivalent for text content?

由 孤人 提交于 2019-12-03 14:31:46
I have some data that I want to present in a FlowDocument . This will basically be a view that explains the data in a friendly way, with section headers, paragraphs of text, etc., and which I will display in a FlowDocumentScrollViewer. To this end, I would like to create a bulleted list ( <List> ) out of the contents of an ObservableCollection . I know how to do that with ItemsControl , but how do I do it for ListItem elements in a FlowDocument , since they're part of the TextElement class hierarchy rather than the Control hierarchy? Is there an equivalent of ItemsControl for text content

“BindingExpression path error” using ItemsControl and VirtualizingStackPanel

由 守給你的承諾、 提交于 2019-12-03 14:12:43
问题 I'm using Silverlight on Windows Phone 7. Is it normal to get loads of "BindingExpression path error" debug messages when using a VirtualizingStackPanel? I think it is happening because the visual items are temporarily unbound from the data items collection as they are recycled ... I have an ItemsControl whose ItemsPanel's ItemsPanelTemplate is a VirtualizingStackPanel. It binds to a "Notes" ObservableCollection on my ViewModel. <ItemsControl x:Name="ListView" ItemsSource="{Binding Notes}"

ItemsControl missing vertical scrollbar

I have the below ItemsControl which wraps items perfectly but it does not have a vertical scrollbar so I can not see the wrapped items. How can I get the scrollbar to show? <ItemsControl x:Name="tStack" Grid.Column="0" Grid.Row="1" ItemsSource="{Binding Shows.View}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderThickness="0.5"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel Orientation="Horizontal" HorizontalAlignment="Left" VerticalAlignment="Top"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Viewbox

Multiple user controls share collection dependency property

由 牧云@^-^@ 提交于 2019-12-03 11:13:06
I have implemented my own usercontrol based on listboxes. It has a dependency property with type of a collection. It works fine when I have only one instance of the usercontrol in a window, but if I have multiple instances I get problem that they share the collection dependency property. Below is a sample illustrating this. My user control called SimpleList: <UserControl x:Class="ItemsTest.SimpleList" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="_simpleList"> <StackPanel> <TextBlock Text="{Binding Path=Title,

ItemsControl, ItemsPanel and ItemsPresenter (Silverlight, XAML)

由 随声附和 提交于 2019-12-03 11:06:47
问题 I'm utterly confused by these 3 terms, when to use which? What's the relationship and they are children of which controls? Is it correct to say this is the tree: ItemsControl > ItemsPresenter > ItemsPanel 回答1: ItemsControl is conceptually a control that houses items. Try to simply think of this control as a holder for zero or more objects. ItemsPresenter is a bit tougher to explain, but this is part of the ItemsControl template that will define where the items are placed within it. Your

Specify ControlTemplate for ItemsControl.ItemContainerStyle

问题 The following is similar to what I'm trying to accomplish. However, I get the error Invalid PropertyDescriptor value. on the Template Setter . I suspect it's because I didn't specify a TargetType for the Style ; however, I don't know the container type for ItemsControl . <ItemsControl> <ItemsControl.ItemContainerStyle> <Style> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <StackPanel> <TextBlock Text="Some Content Here" /> <ContentPresenter /> <Button Content="Edit" /> <

Scrolling to an element of a virtualising ItemsControl

由 99封情书 提交于 2019-12-02 23:57:58
I have a ItemsControl which displays its items in a ScrollViewer , and does virtualisation. I am trying to scroll that ScrollViewer to an (offscreen, hence virtualised) item it contains. However, since the item is virtualised, it doesn't really exist on the screen and has no position (IIUC). I have tried BringIntoView on the child element, but it doesn't scroll into view. I have also tried manually doing it with TransformToAncestor , TransformBounds and ScrollToVerticalOffset , but TransformToAncestor never returns (I guess also because of the virtualisation, because it has no position, but I
