阅读更多关于 WPF InputBinding Ctrl+MWheelUp/Down Possible?

问题 Is there a way I can bind a Command to Ctrl+MWheelUp/Down ? U know in a browser, you can do the same to increase/decrease font size? I want to replicate that effect in WPF. Possible? I was looking at InputBinding > MouseBindings and MouseAction does not seem to support Mouse Scrolls. * I seem to have posted a similar question, but can't find it anymore 回答1: It can be done using very simple custom MouseGesture: public enum MouseWheelDirection { Up, Down} class MouseWheelGesture:MouseGesture {

How to specify multiple file types for Azure Function Blob Trigger input binding?

阅读更多关于 How to specify multiple file types for Azure Function Blob Trigger input binding?

问题 I'm looking to only allow the upload of specific filetypes to Azure Storage to trigger an Azure Function. Current function.json file: { "scriptFile": "__init__.py", "bindings": [{ "name": "myblob", "type": "blobTrigger", "direction": "in", "path": "{name}.json", "connection": "storage-dev" }] } Would I just add another path value like this... "path": "{name}.json", "path": "{name}.csv" ...or an array of values like this... "path": [ "{name}.csv", "{name}.json" ] Can't seem to find an example

KeyBinding on a TreeViewItem

问题 I have a typical treeview and a viewmodel. The viewmodel has an observable collection of other viewmodels that serves as a data source for the tree. public class TreeViewVM { public ObservableCollection<ItemVM> Items { get; private set; } public ItemVM SelectedItem { get; set; } } and the ItemVM : public class ItemVM { public string Name { get; set; } public ImageSource Image { get; private set; } public ObservableCollection<ItemVM> Children { get; private set; } public ICommand Rename { get;

WPF Keyboard Modifier on MouseBinding

问题 I'm working with the MVVM pattern in WPF (a bit new to both). I'd like to set up an InputBinding on a CheckBox that corresponds to a Control + Click event, but do not see a Modifiers property on the MouseBinding element. This is what I'd like to achieve (fictitious code, obviously- Modifiers doesn't exist): <CheckBox> <CheckBox.InputBindings> <MouseBinding MouseAction="LeftClick" Command="{Binding CheckboxControlClickCommand}" Modifiers="Control" /> </CheckBox.InputBindings> </CheckBox> Any

问题 I want to detect when a user clicks on an item on a listview, without using events as I do command binding and I don't like all the nonsense of the behaviours. I have tried this: <ListView x:Name="MainList" Margin="2,8,6,8" Background="Black" ItemsSource="{Binding Path=AssetsVM.Data, Mode=OneWay}" BorderBrush="{x:Null}" > <ListView.InputBindings> <MouseBinding Command="{Binding Path=AssetsVM.SelectActivo}" CommandParameter="{Binding ElementName=MainList, Path=SelectedItem}" MouseAction=

If we can't bind a MouseBinding's Command, what are we supposed to do?

阅读更多关于 If we can't bind a MouseBinding's Command, what are we supposed to do?

I would love to be able to use a regular MouseBinding to capture a CTRL-Click event on my TextBlock . Unfortunately the Command property is not a dependency property and I'm using MVVM, so I can't bind it to my viewmodel. How could Microsoft have left out this basic functionality? Are there no easy ways to detect CTRL-Clicks and bind them to a command in my viewmodel? You could always take a look at using Attached Command Behaviours . Originally I believe I was referring to the use of TextBlock 's InputBindings member. In .NET 4 InputsBinding s now inherit from Freezable , so now the Command

Defining InputBindings within a Style

阅读更多关于 Defining InputBindings within a Style

I'm creating a WPF app using the MVVM design pattern, and I'm trying to extend the TabItem control so that it closes the tab when the user clicks the middle mouse button. I'm trying to achieve this using InputBindings, and it works very well until I try to define it within a style. I've learned that you cannot add InputBindings to a style unless you attach it using a DependencyProperty. So I followed this similar post here... and it works... almost. I can close one tab using the middle mouse button, but it won't work on any of the other tabs (all of the tabs are added at runtime and inherit
