Collection of Xamarin CheckBox with Command event via c#

[Yas]

Hi guys,

Would like to have a help to render checkboxlist with command and command parameter via c# code.

I need the equivalent of XAML code "{Binding .}"

See my attached file for the sample control generator i used.

Sample code:

public async Task<StackLayout> CreateCheckboxList(ControlModel model, ICommand command = null)

        {

            try

            {

                var inputHelper = new ControlDto()

                {

                    Name = model.ID,

                    ID = model.ID,

                    Label = model.Label,

                    ControlType = model.ControlType,

                };

                var source = new ObservableCollection<DataSourceDto>

                {

                    new DataSourceDto(){DisplayText = "Option 1", ID = 1, IsChecked = false },

                    new DataSourceDto(){DisplayText = "Option 2", ID = 2, IsChecked = false },

                    new DataSourceDto(){DisplayText = "Option 3", ID = 3, IsChecked = false },

                    new DataSourceDto(){DisplayText = "Option 4", ID = 4, IsChecked = false },

                    new DataSourceDto(){DisplayText = "Option 5", ID = 5, IsChecked = false },

                };

                var layout = new StackLayout();

                var template = new DataTemplate(() =>

                {

                    var control = new SfCheckBox();

                    var grid = new Grid();

                    control.SetBinding(SfCheckBox.TextProperty, "DisplayText");

                    control.SetBinding(SfCheckBox.IsCheckedProperty, "IsChecked");

                    //==NEED THE EQUIVALENT OF XAML CODE "{Binding .}"

                    //var evnt = new EventToCommandBehavior()

                    //{

                    // EventName = EventName.StateChanged,

                    // Command = command,

                    // CommandParameter = "{Binding .}",

                    //};

                    //control.Behaviors.Add(evnt);

                    grid.Children.Add(control);

                    return grid;

                });

                BindableLayout.SetItemsSource(layout, source);

                BindableLayout.SetItemTemplate(layout, template);

                return await Task.FromResult(layout);

            }

            catch (Exception ex)

            {

                Debug.WriteLine($"{ex.GetType().Name + " : " + ex.Message}");

                throw ex;

            }

        }

Hi Abdiel, 

 

We analyzed your query “Equivalent c# code for “{Binding.}” “, and we would like to let you know that "{Binding .}" simply equals to new Binding(".") in c#. Please see below code snippet for you reference. 

 

var evnt = new EventToCommandBehavior() 

  { 

         EventName = StateChanged, 

         Command = command, 

  }; 

 evnt.SetBinding(EventToCommandBehavior.CommandParameterProperty, "."); 

 control.Behaviors.Add(evnt); 

 

Please let us know if you need further assistance on this. 

 

Thanks,  

Gayathri M.
