Multiselect ListView Without ctrl

[daveonion]

Hi,

I am creating an app which will be touch screen, I have a listview and i want the user to be able to select, deselect items by clicking once on each item. The problem is currently you have to hold ctrl down to select multiple does anybody know how to do it without ctrl.
Thanks in advance

Why don't you forgo the .SelectedItems collection and just go with .CheckedItems? CheckedItems is more inline with what you are doing. I understand you are using a touchscreen, and it would be difficult to force the user to touch on the checkbox, but you could use the following code to check the item once touched.

Public Class Form2
    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.ListView1.HideSelection = True
        Me.ListView1.MultiSelect = False
    End Sub

    Private Sub ListView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDown
        Dim lvi As ListViewItem = Me.ListView1.GetItemAt(e.X, e.Y)
        If Not lvi Is Nothing Then
            lvi.Checked = Not lvi.Checked
            If lvi.Checked Then lvi.BackColor = Color.Blue : lvi.ForeColor = Color.White Else lvi.BackColor = Color.White : lvi.ForeColor = Color.Black
        End If
    End Sub
End Class
