You'd have to handle the ItemChecked event of the ListView, which will give you the item that was clicked on. You'd then have to set a static flag in the event handler that will signal that you are changing check marks. Iterate over the items in the list, changing each check mark, then reset the flag. Since changing the check mark will fire the same event again, the handler code has to start by check that flag. If it's set, then the handler code can exit without making any changes. But, wouldn't this be a job for RadioButtons?? After all, this is exactly what they do.

Hello, Please try this code. I believe this should assist you.
Private Sub ListView1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck For i As Integer = 0 To Me.ListView1.Items.Count - 1 If i <> e.Index Then Me.ListView1.Items(i).Checked = False End If Next End SubRegards, AllenAllen Smith Software Engineer ComponentOne LLC www.componentone.com
