C# WPF ListView Column Header Tooltip.

C# WPF에서 ListView를 동적으로 만드는 경우 Column Header에 Tooltip을 추가하는 방법입니다.

        private void GridViewColumnHeader_Loaded(object sender, RoutedEventArgs e)
        {
            GridViewColumnHeader columnHeader = sender as GridViewColumnHeader;
            if (columnHeader.Content == null)
                return;
            string strHeader = columnHeader.Content as string;

            ColumnItem item = Array.Find(cColumnItems, x => x.strHeader.Equals(strHeader));
            columnHeader.ToolTip = item.strTooltip;
        }
    

ListView 동적으로 만드는 소스도 첨부합니다.

샘플은 DataTemplate도 동적으로 만들어 본 예제입니다.
