问题 I want to check whether font is bold or not and also its color in codedui testing. I am using wpftext control . Please help me. 回答1: Saran, Unfortunately, this is not as straightforward as it probably should be, but it can be done by creating a CodedUI Test Framework Extension which sets an AutomationProperties.ItemStatusProperty to the current Font. One benefit of doing it this way is that it works with the test recorder and allows you to generate assertions and/or hand-code validations.

问题 I'm trying to convert XAML control to XPS document, but i'd like to do this in batch mode - render control in memory and print it to XPS without rendering it on the screen. This project should work even without GUI. I've read Related topic on stackoverflow, but it's not working properly. I can create control, set DataContext, but output xps is empty. If i render control on the screen and then print it, everything is ok, but if i'd like to do this in batch mode, i got empty document (there was

问题 I have a ListBox control with a vertical scrollbar. I would like to increase the Repeat Buttons' Height to something bigger because our UI is touch-compatible. Is there a simple way to do it ? Thank you and best regards, Romanin 回答1: Easiest is to modify the ControlTemplate for a vertical scrollbar and change it to what you want: ScrollBar ControlTemplate Example 回答2: It's not so easy to just change the button sizes, because they are hardcoded in the default template. But you can scale the

问题 I need a control to allow users to add/delete/edit rows of key/value pairs. What's the best control to use for this? Does anyone have an example? I'm quite new to WPF. 回答1: I'd use a simple dialogue with two labelled text boxes, the new pair would be added to the original data which should be bound to the DataGrid so that rows are generated automatically. Edit: A DataGrid example solution. XAML: <Window ... DataContext="{Binding RelativeSource={RelativeSource Mode=Self}}"> <StackPanel

问题 In an application of mine, I'm using the WPF autocomplete box from the wpf toolkit. I'm implementing it via the MVVM pattern. The binding works fine, but I have a small problem when trying to clear the content of the autocompletebox. Setting the bound property in the viewmodel to null, clears the text only partially (all text entered via the keyboard is not cleared - i.e. if I enter CH when fetching all the cities and select Chicago and the set the bound property to null, the CH is not being

问题 I've done a lot of searching on SO and google around this problem, but can't seem to find anything else to try. I have a MainView (window) that contains a tab control. The tab control binds to an ObservableCollection of ChildViews (user controls). The MainView's ViewModel has a method that allows adding to the collection of ChildViews, which then creates a new tab.
