Analogue ProcessCmdKey in WPF

Question

I am new to WPF and WinForms to add hotkeys to the form that I usually used ProcessCmdKey , which made it easy to redefine (add) key functions (similar to the one described below). Is there an easy way to assign hotkeys in WPF? I use commands with keys, but sometimes it doesn’t work (I think that some other controls in the window respond to these gestures and perform their tasks, so my command cannot respond to a predefined key gesture).

Answer 1

InputBindings have the control area to which they are assigned, if you assigned KeyBinding to Window.InputBindings , they will be triggered throughout the window if the same gesture is not locally redefined if it is defined somewhere down the tree.

For example:

 <UserControl.InputBindings> <KeyBinding Gesture="CTRL+SHIFT+N" Command="{Binding BtnNewChild_Command}" CommandParameter="{Binding ElementName=view}" /> </UserControl.InputBindings> 

does not work, it cannot pass a view element as a parameter, since this UserControl has a control named "view". Does wpf have some “common” hotkey assignment scenario?

The problem here will be just a scope, child controls have access to things declared above in the tree, but not vice versa. You could reorganize this to create your view as a resource in UserControl.Resources , then you can refer to it both in CommandParameter and if you use it in UserControl .
