How to: Change the Order of Columns in the Windows Forms DataGridView Control Using the Designer
When you bind a Windows Forms DataGridView control to a data source, the display order of the automatically generated columns is dictated by the data source. If this order is not what you prefer, you can change the order of the columns using the designer. You may also want to add unbound columns to the control and change their display order. For information about how to change the column order programmatically, see How to: Change the Order of Columns in the Windows Forms DataGridView Control.
The following procedure requires a Windows Application project with a form containing a DataGridView control. For information about setting up such a project, see How to: Create a Windows Forms application project and How to: Add Controls to Windows Forms.
