ListView: Change text for selected item

[Discorez]

I use ListView with SingleLine items, and I want modify text for selected item
Problem - item contains old value of text, but by another long click I see, what InputDialog gets the text with new value from item... How I can update item text?

Type ListViewData (Text As String) ' "dimed" in Sub Globals

Sub lvNames_ItemLongClick (Position As Int, Value As Object)
   Dim TD As InputDialog
   Dim lvd As ListViewData

   lvd = Value
   TD.Input = lvd.Text
        If TD.Show("Edit text", "", "OK", "Cancel", "", Null) = DialogResponse.POSITIVE Then
             lvd.Text = TD.Input
        lvNames.Invalidate
   End If
End Sub

Since I don't see a setItem method, probably you should reconstruct the listView after your changes. For example, you can have all items stored in a list (not listview) and then repopulate your listview with it, after a clear. If not having a very large list, you could also try using a scrollview, which would make replacements more straight forward.

I made this, but this decision is very inelegant...

setItem method

it would be very useful

Post #7 - suggests using the scroll view instead

Button Modify

Updates SelectedItems scrollView - which is NOT a listView

Sub btnModif_Click
    Dim row(NumberOfColumns) As String
    
    row(0)=edtCode.Text
    row(1)=edtFirstName.Text
    row(2)=edtLastName.Text

    SQL1.ExecNonQuery("UPDATE table1 Set Code = '"&row(0)&"', First = '"&row(1)&"', Name = '"&row(2)&"' WHERE Code = '" & GetView(SelectedItems.Get(0),0).Text & "'")
    
    For i=0 To NumberOfColumns-1
        SetCell(SelectedItems.Get(0),i,row(i))
    Next
    
End Sub

Use CustomListView instead: [Class] CustomListView - A flexible list based on ScrollView
