ListBox.Selected - Xojo Documentation

See Getting the list of selected rows

Var selectedRows() As Integer // Will hold the index of each selected row

For row As Integer = 0 To ListBox1.LastRowIndex
  If ListBox1.Selected(row) Then
    selectedRows.AddRow(row) // This row is selected
  End If
Next

Hi,

Will it work in older version of xojo ?
I am still using 2018r4.

thanks

If you use the in built language reference (edit>options>use built-in documentation) then you can search your local documentation for the same page(listbox.selected) which will include the correct edition of the code for the version of xojo you’re using, so you’ll need:

Dim selectedRows() As Integer // Will hold the index of each selected row

For row As Integer = 0 To ListBox1.ListCount - 1 // Rows are zero-based
  If ListBox1.Selected(row) Then
    selectedRows.Append(row) // This row is selected
  End If
Next

I want to explain my goals,

I have a listbox with some rows, I want to change the value of the listbox while the user is selecting more than a row.
here is the code,

    dim o as integer
    for o = 0 to listbox1.liscount-1

    if listbox1.selected(o) then 'select more rows by pressing Ctrl button
    label1.text="user select multi rows"
    'replace the value of listbox
    else
    label1.text="user select 1 row only"
    'do nothing
    end if

thanks

You want to change the values of multiple rows all at the same time, the multiple rows that are currently selected?

7

Do you want to compute the values found in the selected Rows and put the result into another Cell ?

8

Listbox.selcount will tell you how many rows are selected.
