# Bertuzzi.MAUI.MultiSelectListView

 Select multiple rows in a listview with .net MAUI.

 

 By default the listview control lets you only select one row at a time. The MultiSelectListView control uses a modified ObservableCollection to mark which rows have been selected.

 

 You can use any image to mark the selected row.

 

 ###### This is the component, works on iOS and Android.

**Platform Support**

MultiSelectListView is a .NET MAUI library.

## Setup / Usage

Basically the key is to use the MultiSelectObservableCollection instead of the conventional ObservableCollection.

```csharp

public MultiSelectObservableCollection Users { get; }

```

The "IsSelected" property notifies when an object has been selected.

in the Xaml file we must declare our control xmlns:lv="clr-namespace:Bertuzzi.MAUI.MultiSelectListView;assembly=Bertuzzi.MAUI.MultiSelectListView" , for example . 

Then use the new MultiSelect.Enable property to enable the multiple selection in the listview.

we must use the SelectableCell that contains the property to inform the icon of the selection

```csharp

    

        

            

                

                    

                        

                            

                        

                        

                            

                                

                            

                        

                    

                

            

        

    

```

## SelectedItemBehavior

SelectedItemBehavior to execute the command when the SelectedItem event occurs in ListView. Pass the item selected in ListView to Command. 

Based on SelectedItemBehavior by [Atsushi Nakamura](https://github.com/nuitsjp) (https://github.com/nuitsjp/Xamarin.Forms.BehaviorsPack).

If ClearSelected property is true, SelectedItem property of ListView is cleared after command execution. Default ClearSelected property value is true.

You can use the object of the selected line

```csharp

  

        

  

```

Or specify the property you want to pass as a parameter

```csharp

  

       

```
