阅读更多关于 [UWP][XAML] ListView child item not using full width

问题 I'm trying to display a list of bound items. I've customized the datatemplate to be a grid and I want the right column (that has a fixed width) to stick to the right side of the screen, and the 1st column I want to fill the remaining space.

阅读更多关于 Keep ListView.HeaderTemplate visible/static/sticky in UWP

I need to keep the HeaderTemplate of a ListView visible at all times, but I don't know what to set, or what part of the ListView 's template to change to do that.

How can I keep the header "row" of the ListView visible even when scrolling through the ListView 's items??

Changing value of a ThemeResource at runtime does not reflect in other views

阅读更多关于 Changing value of a ThemeResource at runtime does not reflect in other views

I am using custom themedictionary in my UWP app. I change the value of a ThemeResource at runtime. This change is reflected only in the mainview and not the other views. Even if i create a new view after changing the resource's value the new view uses only the intial value of the resource. Is there anything I'm doing wrong? This is how I change my resource's value. (Application.Current.Resources["BackgroundBrush"] as SolidColorBrush).Color = Windows.UI.Colors.Black; My Secondary View's XAML: <Grid Background="{ThemeResource BackgroundBrush}"/> Even my main view has the same XAML. Here's the

问题 Although I know I can get all ControlTemplates from MSDN.,it's not convenient enough.

Use strings in .resw File directly in XAML

阅读更多关于 Use strings in .resw File directly in XAML

问题 I know the usual way to reference localized strings from a .resw file would be like this: XAML: <Button x:Uid="ButtonUid" /> Resources.resw: ButtonUid.Content = "Hello World" But is it also possible to kind of do it like this: XAML (pseudo code): <Button Content = "$buttonLabel" /> Resources.resw: buttonLabel = "Hello World" The reason why I want to do it like in the second exapmle is because this is an app that I'm porting from iOS and Android to WP. I'd like to convert the iOS or Android
