ListView Final Column Autosize creates scrollbar

Question

I am implementing a custom control which derives from ListView.

I would like for the final column to fill the remaining space (Quite a common task), I have gone abou

Answer 1

When a form containing a listview is restored to FormWindowState.Normal from a maximized state, horizontal scroll bar is displayed even though column widths have been correctly adjusted. This happens when the resized column width shrinks but not when it grows. Here's a hack that can correct this without resorting to win32 calls. (magic number [-2] is just a simple shortcut)

        // Member variable.
        private ListView myListView;

        // Method to resize last column.
        private void ResizeColumn(int width) {
              myListView.Columns[myListView.Columns.Count - 1].Width = width;
        }                  

        // ListView ClientSizeChanged event handler.
        private void Process_ListViewClientSizeChanged(object sender, EventArgs e)
        {
              // Get the width to resize the last column.
              int width = myListView.ClientSize.Width;
              for (int i = 0; i < myListView.Columns.Count - 1; i++)
                    width -= myListView.Columns[i].Width;

              // Last column width is growing. Use magic number to resize.
              if (width >= myListView.Columns[myListView.Columns.Count - 1].Width)
                    myListView.Columns[myListView.Columns.Count - 1].Width = -2;

              // Last column width is shrinking. 
              // Asynchronously invoke a method to resize the last column.
              else
                    myListView.BeginInvoke
                          ((MethodInvoker)delegate { ResizeColumn(width); });
        }
