xaml

问题 I have what I'm sure is a ridiculously ignorant question, but I'm asking it anyways because I've searched and searched and either don't understand the solutions I'm seeing or not finding exactly the answer I seek. I have an MVVM application. My XAML is setup with the DataContext set to the VM where the data items on the screen are populated from the VM's properties. My CodeBehind doesn't fiddle with the data, only things relating to the screen. What I want to do now is bind certain UI

问题 I have a situation where I am animating part of my XAML application, and I need to wait for the animation AND rendering to complete before I can move on in my code. So far the tail end of my function looks like: ProcExpandCollapse.Begin(); while (ProcExpandCollapse.GetCurrentState() != ClockState.Stopped) { } } Which, in theory, will wait until the animation is finished. But it will not wait until the rendering is finished - the thread drawing the application might still not have re-drawn the

问题 I'm trying to use a collection that is a property of another collection to bind to a listbox.

Does anyone know how I can associate the index in my xaml with the property in my viewmodel? 回答1: where index is an integer in my viewmodel, does

问题 I'm trying to add a grid view at the bottom of the screen containing 'Current Playing' information about a media being played in a media player. The problem is that I want this view to be there no matter what is the page visible.

The detail page can be a content page, a navigation page (mostly) or a modal content page. However, if I might only choose one, I would choose it

问题 Is it possible to using XAML data binding to a model with Auto-Implemented properties? class ClassA { // pseudo code. int Width { get; set{ NotifyPropertyChange("Width");} } } //XAML <textBox width="{Binding Path=Width,Mode=OneWay}"/> 回答1: Auto-properties don't have a half auto mode. It needs to either be an auto-property with nothing extra: int Width { get; set; } or a fully expanded property with a backing store that can have additional code added to it, like change notification: int _width
