How to: Add and Remove Columns in the Windows Forms DataGridView Control Using the Designer
The Windows Forms DataGridView control must contain columns in order to display data. If you plan to populate the control manually, you must add the columns yourself. Alternately, you can bind the control to a data source, which generates and populates the columns automatically. If the data source contains more columns than you want to display, you can remove the unwanted columns.
The following procedures require a Windows Application project with a form containing a DataGridView control. For information about setting up such a project, see How to: Create a New Windows Forms Application Project and How to: Add Controls to Windows Forms.
Note
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Working with Settings.
