Passing two command parameters using WPF binding

I need to send two parameters to my RelayCommand, for example:

public RelayCommand<String,Int> MyCommand {get;set;} Or public RelayCommand<EventArgument,String> MyCommand {get;set;} 

Answer 1

Wrap them in an object:

 public RelayCommand<MyModel> MyCommand { get; set; } 

where MyModel will contain two properties:

 public class MyModel { public int Id { get; set; } public string Name { get; set; } } 

Answer 2

You can use a separate model class to pass in several parameters. And to initialize them, you can use xaml elements like this:

 <Button Command="{Binding YourCommand}"> <Button.CommandParameter> <YourNS:YourModel Id="{Binding PathForId}" Name="{Binding PathForName}"/> </Button.CommandParameter> </Button> 

This will create a new MyModel object to pass the command to, and then initialize its properties using bindings.
