How to focus and select text in ListView

BitSmithy 2,141

Hello,

I have such ListView:

        <ListView x:Name="lvFileList" Grid.Row="1" Margin="0,0,0,0"
                  HorizontalOptions="FillAndExpand" VerticalOptions="Start"
                  ItemsSource="{Binding FileList, Mode=TwoWay}"                   SelectionMode="Single"                  
                  ItemSelected="lvFileList_ItemSelected"                
                  >
            <ListView.ItemTemplate>
                <DataTemplate>
                    <ViewCell>
                        <Frame BorderColor="Blue" Padding="0,1,0,0" Margin="0,1,0,1">
                            <StackLayout x:Name="spListItems" Orientation="Horizontal">

                                <Button x:Name="btnSelectList" Width="30" Height="30"
                                Clicked="btnSelectList_Click"></Button>
                                <Entry x:Name="aaa" 
                                HorizontalOptions="FillAndExpand"                 
                                VerticalOptions="FillAndExpand"
                                Text="{Binding Name}"                                     
                                Focused="Entry_Focused"
                             />
                            </StackLayout>
                        </Frame>
                    </ViewCell>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>

Now I populate ListView with data.

When ListView has generated rows I want to focus first Entry in first ListViewItem and next select text in this ENtry.

How to do such task?

Do you want entry to get focus when new item added to the listview?

Will the Entry of latest item get the focus in the Listview?

I want to set focus on the first Entry inside first item. No matters when, It can be set after first item is added to the list or after loading all items.

Will the Entry of latest item get the focus in the Listview?

No, I dont know how to code such behavior in Maui, so I dont started to code it. None of entries in the ListView has focus after loading.

You can invoke the entry.focus when viewcell item appearing and make the keyboard showing. Then your entry will get the focus.

private async void ViewCell_Appearing(object sender, EventArgs e)

        {

            ViewCell viewCell= sender as ViewCell;

            if (sender != null)

            {            // Retrieve the Entry inside the ViewCellvar

                         var entry = viewCell.View.FindByName<Entry>("MyEntry");  

                if (entry != null) {
 
                   await Task.Delay(1000).ContinueWith(t =>{

                        MainThread.InvokeOnMainThreadAsync(() =>

                        {
 
                            entry.Focus();

#if ANDROID

                            Android.Views.InputMethods.InputMethodManager inputManager = (Android.Views.InputMethods.InputMethodManager)Android.App.Application.Context.ApplicationContext.GetSystemService(Android.Content.Context.InputMethodService);

                            inputManager.ToggleSoftInput(Android.Views.InputMethods.InputMethodManager.ShowForced, Android.Views.InputMethods.HideSoftInputFlags.ImplicitOnly);

#endif

                        });

                    });

                    // or manipulate it as needed

                 }

            }

        }
