Handling ListView Check Changes

[Guest]

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. ;-)
