Example

This example shows how to create a custom command with a parameter and execute it when a user taps the start icon.

1. In a view model, create a command that implements the ICommand interface:

   C#

   using System.ComponentModel;
   using System.Windows.Input;
   
   namespace TestICommand.ViewModels {
       public class CopyCommand : ICommand {
           public event EventHandler CanExecuteChanged;
   
           MainViewModel viewModel;
           public CopyCommand(MainViewModel viewModel) {
               this.viewModel = viewModel;
           }
   
           public bool CanExecute(object Login) {
               return true;            
           }
   
           public void Execute(object Login) {
               viewModel.LoginText = viewModel.NameText;
           }
       }
   
       public class MainViewModel : INotifyPropertyChanged {
           public MainViewModel() {
               iconCommand = new CopyCommand(this);
           }
   
           ICommand iconCommand = null;
           public ICommand IconCommand {
               get { return iconCommand; }
               set { 
                   if (iconCommand != value) {
                       iconCommand = value;
                       OnPropertyChanged("IconCommand");
                   }
               }
           }
   
           public event PropertyChangedEventHandler PropertyChanged;
           protected void OnPropertyChanged(string name) {
               PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
           }
   
           string loginText = "";
           public string LoginText {
               get { return loginText; }
               set {
                   loginText = value;
                   OnPropertyChanged("LoginText");
               }
           }
   
           string nameText = "";
           public string NameText {
               get { return nameText; }
               set {
                   nameText = value;
                   OnPropertyChanged("NameText");
               }
           }
       }
   }
   

2. Bind the specified command to the StartIconCommand property and define the StartIconCommandParameter value:

           <dxe:TextEdit x:Name="NameEditor" 
                         Text="{Binding NameText}"
                         LabelText="First Name"/>
   
           <dxe:TextEdit x:Name="LoginEditor" 
                         Text="{Binding LoginText}" 
                         LabelText="Login" 
                         StartIcon="icon" 
                         StartIconCommand="{Binding IconCommand}" 
                         StartIconCommandParameter="{Binding Source={x:Reference NameEditor}, Path=Text}"
                         HelpText="Tap the icon to use your first name as login"/>
       </StackLayout>
