xaml

问题 I have just started working in Xamarin and am writing an App targeting iOS and Android. I'm trying to keep pretty much all of my UI design in the common library between them and am starting to find the lines a bit blurred. My current requirement is to disable the auto-capitalisation on the 'Entry' tag object in XAML. Is this something that can be done by markup? I cannot find any property that would support this behaviour. If not, what should I do instead? 回答1: If you plan to use this

问题 I have a WPF application in which I want to convert a TextBox into a RichTextBox. I have already written the following lines of code: <RichTextBox> <FlowDocument> <Paragraph> <Run Text="{Binding GeneralDescription}" /> </Paragraph> </FlowDocument> </RichTextBox> This has the effect that the string GeneralDescription is displayed and I can edit and format it. Now I have the problem that when I mark a part of the text, format it (e.g. make it bold), save the document and re-open the document,

问题 I have a button with transparent background.

问题 I'm trying to implement a kind of collapsable StackLayout. Every tine the user clicks the button, it expands or collapse the stacklayout to show/hide more details. I was able to achieve more/less this with the code below, but it doesn't look right and the effect isn't great, because it grows immediately and I'm applying the effect to other element. Do you have any suggestions to do this, I'm using xamarin Forms? XAML <?xml version="1.0" encoding="utf-8" ?> <StackLayout xmlns="http://xamarin

问题 I'm creating a WPF application using MVVM. I have a textbox, which is bound to a property in my ViewModel of type double with a default value of 0.0. If I now enter a text value (say, abc) in the textbox, upon losing focus, the textbox is highlighted indicating an incorrect value.

As the Text property of the textbox is bound to a property of type double in the ViewModel, the ViewModel property contains the

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 6 years ago . On the msdn site there is big article: XAML overview And there is the part describing what is: x:Key, x:Class, x:Name etc. but the problem is that all that said there about it is very abstractional with no examples. I know that when I create an element in xaml and set: x:Name = "abc" then in the cs

问题 I am trying to create a WPF application that presents a login view and after successful login, presents a first, second, and third page (like a wizard). Each "page" including the login view has its respective ViewModel . I have a MainWindow.xaml which holds four UserControls one of which will be visible at any given state. I am having trouble dealing with the orchestration of visibility. It makes the most sense to me that MainWindowViewModel is the one that is responsible for keeping track of

When assigning combo1.ItemsSource = Peoplelist; code-behinde, combobox items in ui are updating, but when I do a binding in xaml: ItemsSource="{Binding Path=Peoplelist}" it is not. What I am missing?

问题 I am new to C# WPF programming and working on a WPF-Application that has to include a legacy ActiveX component. I know ActiveX is kind of dead but I have to use it in this case unfortunately. I use MVVM Light with an IFrameNavigationService as shown in this post. Furthermore I used this example to bind the ActiveX component into the view to follow the guidlines of MVVM which is probalby not the best way in my opinion. On each navigation I have to wait until page is loaded to connect with the
