To configure the sizing mode for headers and rows and for columns that do not override the control value, set one or more of the following Data Grid View properties: To override the control's column sizing mode for an individual column, set its Auto Size Mode property to a value other than Not Set. Note: If you maintain cell values in a custom data cache using virtual mode, automatic sizing occurs when the user edits a cell value but does not occur when you alter a cached value outside of a Cell Value Pushed event handler. In this case, size adjustment occurs whenever cell contents change. Programmatic resizing is useful to avoid performance penalties with continuous resizing. When you programmatically resize columns that have Inherited Auto Size Mode property values of Fill, however, the calculated content-based widths are used to proportionally adjust the column Fill Weight property values, and the actually column widths are then calculated according to these new proportions so that all columns fill the available display area of the control.

Column fill mode causes the visible columns in the control to fill the width of the control's display area.
