Примеры

In this example, the Opening event of a ContextMenuStrip is used to enable or disable the Paste command on the menu. If the Clipboard contains data that can be pasted into the ink in the InkOverlay object, the Paste command on the menu is enabled.

Private Sub menuStrip_Opening(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles menuStrip.Opening
    Me.miPaste.Enabled = mInkOverlay.Ink.CanPaste()
End Sub

private void menuStrip_Opening(object sender, CancelEventArgs e)
{
    this.miPaste.Enabled = mInkOverlay.Ink.CanPaste();
}
