Listview - Select (and stay selected) on click?

[Static]

I think im being stupid about this.. or maybe its too early.... lol

I am trying to make my Listview a select/deselect by click (like checked) so you can select multiple rows without having to hold shift.

click selects it, click again on that row and it deselects it?

I once needed to implement this using drag. Maybe you could modifies it to suit your needs

Public Class Form1
 
    Private m_mouseDown As Boolean
 
    Private Sub ListView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDown
        Me.m_mouseDown = True
    End Sub
 
    Private Sub ListView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDown
        If Me.m_mouseDown Then
            Dim i = ListView1.HitTest(e.Location).Item.Index
            ListView1.Items(i).Selected = True
        End If
    End Sub
 
    Private Sub ListView1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseUp
        Me.m_mouseDown = False
    End Sub
 
End Class

ooo! Hittest! forgot about that.. brb thanks!

EDIT: it wont "stick" unless i move the mouse off the line...

I guess creating a List(Of Integer) would be sloppy hmm

bah.. thought this would work

Private Sub LV1_MouseClick(sender As Object, e As MouseEventArgs) Handles LV1.MouseClick
        Dim ITM As ListViewItem = LV1.Items(LV1.HitTest(e.Location).Item.Index)
        For Each LI As ListViewItem In LV1.SelectedItems
            If LI Is ITM Then LI.Selected = Not LI.Selected
            If LI.SubItems(2).Text = WeekOf.ToString Then LI.Selected = False 'This is making sure you dont pick the current week row...

        Next
    End Sub

but its deselecting the one i just selected...


also sloppy...

Private Sub LV1_MouseClick(sender As Object, e As MouseEventArgs) Handles LV1.MouseClick

        Dim ITM As ListViewItem = LV1.Items(LV1.HitTest(e.Location).Item.Index)
        If ITM.SubItems(10).Text = "0" Then ITM.SubItems(10).Text = "1" Else ITM.SubItems(10).Text = "0"
        For Each LI As ListViewItem In LV1.Items
            If LI.SubItems(10).Text = "1" Then LI.Selected = True Else LI.Selected = False
            If LI.SubItems(2).Text = WeekOf.ToString Then LI.Selected = False : LI.SubItems(10).Text = "0" 'This is making sure you dont pick the current week row...

        Next
    End Sub

but it works... it just seems wrong lol


EDIT: i didnt even think of using a list! lol thats better than a "flag"

so creating a boolean list works also...
Dim ListItemSelected As New List(Of Boolean)

Private Sub LV1_MouseClick(sender As Object, e As MouseEventArgs) Handles LV1.MouseClick
        Dim I As Integer = LV1.HitTest(e.Location).Item.Index
        ListItemSelected(I) = Not ListItemSelected(I)
        For Each LI As ListViewItem In LV1.Items
            LI.Selected = ListItemSelected(LI.Index)
            If LI.SubItems(2).Text = WeekOf.ToString Then LI.Selected = False 'This is making sure you dont pick the current week row...

        Next
    End Sub

but again... seems a bit sloppy lol - better than my idea though!

Because you deselect it.

If LI Is ITM Then LI.Selected = Not LI.Selected

yeah... i was thinking the "selection" occurred after the click. nope! lol

you list idea is the best so far though.
