Handling ListView Check Changes

Hello,

I have a ListView control in Details view. When an item is un-checked, I
want to change the ForeColor.

The only way I have found to do this is to loop through all the items of the
ListView in its Click, DoubleClick, and KeyPress events using the sub below
. However, the ListView can potentially hold hundreds of items, so this
would be quite slow.

Is there a better way to handle when an item is checked/un-checked?

Thank you,

Eric

\\\
Private Sub HandleCheckChange()
Dim item As ListViewItem
For Each item In lvwDirectories.Items
If item.Checked Then
item.ForeColor = SystemColors.WindowText
Else
item.ForeColor = SystemColors.GrayText
End If
Next
End Sub

What about ListView.ItemCheck event. Didn't it do the trick for you?

Oh, brother. I didn't even see the ItemCheck event. Thank you for your
help, Stoitcho.

Please accept my apologies for my ignorance. ;-)
