Find the last item selected in a MultiSimple listbox...

Find the last item selected in a MultiSimple listbox...

• SARay

  Works very well. The only thing I would add would be a "Last Clicked Item" property, since the last selected item is not always the last clicked item.

  Code Snippet

  Private _LastSelectedItem As New Object

  Public ReadOnly Property LastSelectedItem() As Object
  Get
  If IsNothing(_LastSelectedItem) Then
  Return Nothing
  Else
  Return _LastSelectedItem
  End If
  End Get
  End Property

  Private _LastClickedItem As New Object

  Public ReadOnly Property LastClickedItem() As Object
  Get
  If IsNothing(_LastClickedItem) Then
  Return Nothing
  Else
  Return _LastClickedItem
  End If
  End Get
  End Property

  Protected Overrides Sub OnClick(ByVal e As System.EventArgs)
  Dim posX As Integer = mylistbox.MousePosition.X
  Dim posY As Integer = mylistbox.MousePosition.Y
  Dim lastitem As Object = Me.Items(Me.IndexFromPoint(Me.PointToClient(New Drawing.Point(posX, posY))))

  _LastClickedItem = lastitem

  If Me.SelectedItems.Contains(lastitem) Then
  _LastSelectedItem = lastitem
  End If
  MyBase.OnClick(e)
  End Sub

  To find the last Item selected in a multi select

  Dim s as string = Me.ListBox1.SelectedItems(Me.ListBox1.SelectedItems.Count - 1).ToString

  which is the last item added to the collection

  latestIndex always comes back as the last item in the selecteditems collection. I'm trying to find out which item in the selecteditems collection was clicked. For examle if they click "ALL", I want to get an index of 0. If they click "555", I want to get an index of 5, etc.

  In this example, latestIndex is always the highest integer index of all the selected items. So, if you click "ALL", it is 0. Then you click "555", it is 5. Then, you click "333" it is 5 again. and so on until you click an item that has a higher index than the current highest index.

  Hi,

  Did you try this (code is in C#-sorry)

  private void ListBox1_MouseDown(object sender, MouseEventArgs e)

  {

  System.Windows.Forms.ListBox.SelectedIndexCollection coll= this.ListBox1.SelectedIndices;

  int latestIndex = coll[coll.Count - 1];//Get latest selected index

  which may replace

  index = CType(sender, ListBox).IndexFromPoint(pt)

  }

  Maybe I confused the question. I'm not looking for the last item added to the selecteditems collection. I'm looking for the last (or current) item (text in this case) that was clicked on.

  This custom list box adds a property that shows the last item that was selected.....

  Code Snippet

  Public Class mylistbox

  Inherits ListBox

  Private _LastSelectedItem As New Object

  Public ReadOnly Property LastSelectedItem() As Object

  Get

  If IsNothing(_LastSelectedItem) Then

  Return nothing

  Else

  Return _LastSelectedItem

  End If

  End Get

  End Property

  Protected Overrides Sub OnClick(ByVal e As System.EventArgs)

  Dim posX As Integer = mylistbox.MousePosition.X

  Dim posY As Integer = mylistbox.MousePosition.Y

  Dim lastitem As Object = Me.Items(Me.IndexFromPoint(Me.PointToClient(New Drawing.Point(posX, posY))))

  If Me.SelectedItems.Contains(lastitem) Then

  _LastSelectedItem = lastitem

  End If

  MyBase.OnClick(e)

  End Sub

  End Class
