Delete items of ListView wpf application (Vb.NEt)

Question

Hi everybody,

I need to delete some items in my ListView (wpf application vb).  

For i As Integer = ListView1.SelectedItems.Count - 1 To 0 Step -1
ListView1.SelectedItems(i).Remove()
Next 

When i write this code: the system give me this error: 

An unhandled exception of type 'System.MissingMemberException' occurred in PresentationFramework.dll

Additional information: Le membre public 'Remove' du type 'ListAcquis' est introuvable.

What is the problem there?

by the way, my listview is :

   Private Sub ButtonAdd_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles ButtonAdd.Click


        ListView1.Items.Add(New ListAcquis With
                                {
                                 .TextBoxPasEnri = TextBoxPasEnri.Text,
                                 .TextBoxModem = TextBoxModem.Text,
                                 .TextBoxTypSate = TextBoxTypSate.Text,
                                 .TextBoxAdresse = TextBoxAdresse.Text,
                                 .TextBoxVoie = TextBoxVoie.Text})
        'Effacer text dans les textbox
        TextBoxVoie.Clear()

Hi icor,

This exception represents that you are trying to remove the item which does not exist. Please refer to:http://msdn.microsoft.com/en-us/library/system.missingmemberexception.aspx.

From the code you provided, I think you add the listview item one by one, so you can give the following code a try:

Dim selectedItems = New System.Collections.ArrayList(ListView1.SelectedItems)
'get all the selected items
For Each eachitem As var In selectedItems
	ListView1.Items.Remove(eachitem)
Next

What about var?

I have a problem with var, the system says that is not declarated.

Thanks

Hi icor,

I am sorry for the mistake, var is the keyword in C# language. Please modify the code to:

  Dim selectedItems = New System.Collections.ArrayList(ListView1.SelectedItems)
        'get all the selected items
        For Each eachitem In selectedItems
            ListView1.Items.Remove(eachitem)
        Next

It works well for me.

Regards,
