Question

I have read this topic:
how to delete a specific text / message showed in a ListView ?

It works fine in winform (I have test it!) but in WPF it does not work.

I want to find a text of the firstnametxt in listview1 and compare it to Firstname Column items and if its true then delete the item (the row that contains the item)

But I do not know how to handle this in WPF.

Part of my code is like this:

XAML:

<ListView Name="listView1 HorizontalAlignment="Left" VerticalAlignment="Top" />
    <ListView.View>
        <GridView>
            <GridViewColumn Header="FirstName" DisplayMemberBinding="{Binding Path=FirstName}"  />
            <GridViewColumn Header="LastName" DisplayMemberBinding="{Binding Path=LastName}" />
        </GridView>
    </ListView.View>
</ListView>
<TextBox Name="firstnametxt" Height="27" HorizontalAlignment="Left" Margin="271,20,0,0"  VerticalAlignment="Top" Width="181" />
<Button Content="Add" Height="38" HorizontalAlignment="Left" Margin="310,242,0,0" Name="button1" VerticalAlignment="Top" Width="74" Click="button1_Click" />
<Button Content="Find" Height="38" HorizontalAlignment="Left" Name="button2" VerticalAlignment="Top" Width="74" Click="button2_Click" />

Code behind (C#):

public class Familiy
{
    public Familiy(string firstname, string lastname)
    {
        this.FirstName = firstname;
        this.LastName = lastname;
    }
    private string firstname;

    public string FirstName
    {
        get { return firstname; }
        set { firstname = value; }
    }
    private string lastname;
    public string LastName
    {
        get { return lastname; }
        set { lastname = value; }
    }
}


private void button1_Click(object sender, RoutedEventArgs e)
{

}

Answer 1

You will need to alter the ListBox’s ItemSource wether it be a ItemList, List or another collection Type this example uses a List of Familily.

public partial class MainWindow : Window
{
    List<Familiy> familiys = new List<Familiy>();
    public MainWindow()
    {
        InitializeComponent();


        familiys.Add( new Familiy("FirstName1", "LastName1"));
        familiys.Add(new Familiy("FirstName2", "LastName2"));
        familiys.Add(new Familiy("FirstName3", "LastName3"));
        familiys.Add(new Familiy("FirstName4", "LastName4"));
        listView1.ItemsSource = familiys;

    }
    private void button1_Click(object sender, RoutedEventArgs e)
    {
        familiys.Remove(familiys.Find(delegate(Familiy f) { return f.FirstName == firstnametxt.Text; }));
        listView1.ItemsSource = "";
        listView1.ItemsSource = familiys;
    }
}
