How to Pass parameter to a Command in MVVM

Question

View: <Button Command="{Binding GetChangeLogCommand}"

ViewModel: GetChangeLogCommand = new DelegateCommand(GetChangeLog);

Method:

public ICommand GetChangeLogCommand { get; set; } private async void GetChangeLog(bool isLatest) { // code goes here . . . }

I'm going to useGetChangeLogCommand multiple time and pass boolean parameter is it possible with MVVM sorry I'm new with this.

At your Button you can also bind a property called CommandParameter. This value will be passed to your command-handler — Tomtom

If you are that particular to pass the button element to viewmodel You can use below code :

 CommandParameter="{Binding ElementName=YourButtonName}"

You could even pass the entire window, user control, or a particular list or list item to the view model

 CommandParameter="{Binding ElementName=YourWindow}" CommandParameter="{Binding ElementName=Control}"
