Hide all buttons in listview

I was looking for how I can hide all buttons in listview, by calling a function, without needing to populate data to the listview again (not using the ItemDataBound event).

Here's the solution I've found, it's so simple!


private void ShowButtons(bool show)
{
        foreach (ListViewItem item in lvwQuotations.Items)
        {
            ((Button)item.FindControl("btnView")).Visible = show;
        }
}
