The key bindings of the viewer can be retrieved using the KeyBindings property. After that, you can proceed to modify the collection using the public API of the class:
{{region radpdfviewer-keyboard-support_1}} public void Clear() //Clears the collection public void SetInputBindings(InputBindingCollection inputBindings) //Clears the current KeyBindings and sets the new ones.
public void Add(InputBinding inputBinding)
public void AddRange(IEnumerable<InputBinding> inputBindings)
public void RegisterCommand(ICommand command, Key key, ModifierKeys modifierKeys = ModifierKeys.None, object commandParameter = null)
{{endregion}}
Here is an example that shows how the default input bindings can be cleared and two ways of registering new key bindings:
{{region radpdfviewer-keyboard-support_0}} this.pdfViewer.Clear(); this.pdfViewer.KeyBindings.Add(new KeyBinding(this.pdfViewer.Commands.PageUpCommand, new KeyGesture(Key.PageUp))); this.pdfViewer.KeyBindings.RegisterCommandDescriptor(this.pdfViewer.CommandDescriptors.PageDownCommandDescriptor, Key.PageDown); {{endregion}}
