datatemplate

问题 I have been trying to change the color of the first item of my list[0] and also when I tapped on an Item - the color I need to change is the frame and the labels inside it. I tried the following: BackgroundColor="{Binding IsActive, Converter={StaticResource colorConverter}}" This works at the list level only, but nothing inside the data template. What else could I do? <sync:SfListView x:Name="list" SelectionMode="Single" SelectionGesture="Tap" ItemTapped="Day_ItemTapped"> <sync:SfListView

问题 I have a view defined as a DataTemplate (for an "OrderEntryViewModel") with a Menu, ContentPresenter, and Expander inside of a 3-row grid. The content of the ContentPresenter is binded to another viewModel "OrderViewModel" (for which there's another DataTemplate-defined view). The expander has a ZIndex of 99, so that when it expands UP, it expands OVER any other controls (i.e. the ContentPresenter). This all works as expected EXCEPT when the ContentPresenter's content (the OrderViewModel) has

Edit: What i want is a ListBox that places the items like a WrapPanel. 回答1: If I understand you correctly, you can use the ItemsPanel property of your container. I used something similar to make my ItemsControl layout using a horizontal StackPanel: <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal" /> </ItemsPanelTemplate> <

问题 I'm creating a custom ItemsControl that contains a grid for display whatever. I'd like the user to be able to use datatemplates for displaying that whatever, but how do I go about doing that? I know how to create the templates, but I'm not sure how to go about applying a template such that the items are located properly within the grid (my code) and each item is displayed as the user wants (via the datatemplate). -- edit -- There appears to be a little confusion as to what I'm asking. Imagine

问题 I am trying to use the MVVM pattern for the first time. So I have an ItemsControl filled with my viewmodel objects, displayed using DataTemplate 's; the objects are "nodes" and "edges" represented in DataTemplate 's with Thumb and Polyline objects and I want to be able to detect clicks and drags on the ItemsControl in order to move the nodes and edges. Two questions: How do I attach mouse event handlers to the Polyline 's and Thumb 's to be handled by the little viewmodels? (I could attach a
