Context Menu question

[J L]

I have a form with a listview on it and a context menu. I handle the
right click event on the listview but after handling the event, the
context menu then appears. I would like to disable it if the user
right clicks on an item in the listview. I do like it to appear if the
user right clicks on an empty part of the listview.

Can this be done? If so how?

TIA
John

Hi J L,

In mousedown event of the listview:

Dim blnState As Boolean = (e.Button = MouseButtons.Right) AndAlso
(ListView1.SelectedItems.Count > 0)

mnuAdd.Visible = blnstate

mnuRemove.Visible = blnstate
